    - Setting a datacolumns value to NULL? How do I set the value of a specific datarow's column to be null? Ex. Private sub savedata(byval sOID as string, byval sComment as SqlString) Dim ods as dataset Dim odt as datatable Dim odr as datarow Dim odrarray() as datarow try ods = me.getdataset(xxx...) odt = ods.tables(0) odrarray = odt.select("myoid = '" + sOID + "'") for each odr in odrarray If sComment.isNull then ??????? How do I set this particular row/column to be null???

    - DataReader with a return parameter and an OUTPUT parameter. I have a stored procedure and I set up the command type to be StoredProcedure with the return value and the output parameter set to InputOutput. This StoredProcedure also returns a set of rows. From the best that I can tell if I use ExecuteReader() the first time it returns the OUTPUT parameter and it takes a second time to actually get the data. Is this the default behavior or is there some special setup to get this to return the data AND the OUTPUT parameter in one call to ExecuteReader()? Thank you for your suggestions.

    - formatting a label control with a date Probably a simple question: I have a combobox where the user will select a member number. I have two labels that are bound to the member's name (FirstName, LastName). I then have another label that is bound to the member's date of birth. Everything works fine in that when a member is selected from the combobox the name changes and the birthdate changes; however the label for the birthdate is in mm/dd/yyyy format but it also displays the time of 12:00 am. I want to delete the time. Is there a way to do this? Thanks for the information. Brad PS This is an oledb data adapter connecting to an access database. The date field in the database is formatted as short and the date-time picker in VB is a custom format of MMMM dd, yyyy. Tag: Returning Multiple Resultsets with Jet Tag: 72157

    - Inserting identity columns with CommandBuilder generated commands? Hi, I need to commit the changes to the database of a dataset containing many (MANY) datatables. A few of them have an auto-increment column, but I need to insert a specific value in the database (which is MS-SQL, by the way). My code is fine and I send a "SET IDENTITY_INSERT ON" to the database when needed. Since all the operations I need to perform are very basic and that I have many different tables, I am using the CommandBuilder object. The problem is that the Insert command does NOT include the auto-increment field. Is there a way to make the extra parameter is added to my InsertCommand? MSDN and the books I have were not of any help. Thank you very much! Carl PS: Here's the code... Public Sub CommitTable(ByVal table As DataTable, ByVal transaction As SqlTransaction, Optional ByVal allowIdentityInsert As Boolean = False) Dim da As New SqlDataAdapter("SELECT * FROM " + table.TableName, transaction.Connection) da.SelectCommand.Transaction = transaction Dim cmdBuilder As New SqlCommandBuilder(da) Dim cmd As SqlCommand cmdBuilder.QuotePrefix = "[" cmdBuilder.QuoteSuffix = "]" da.InsertCommand = cmdBuilder.GetInsertCommand da.UpdateCommand = cmdBuilder.GetUpdateCommand da.DeleteCommand = cmdBuilder.GetDeleteCommand cmd = New SqlCommand("DELETE FROM " + table.TableName, transaction.Connection, transaction) cmd.ExecuteNonQuery() If allowIdentityInsert Then cmd.CommandText = "SET IDENTITY_INSERT " + table.TableName + " ON" cmd.ExecuteNonQuery() End If da.Update(table) table.AcceptChanges() If allowIdentityInsert Then cmd.CommandText = "SET IDENTITY_INSERT " + table.TableName + " OFF" cmd.ExecuteNonQuery() End If End Sub Tag: Returning Multiple Resultsets with Jet Tag: 72149

    - Using Oracle Packages in Visual Studio.NET 2003 designer Hi Group, we've noticed that Visual Studio.NET 2003 does not seem to be capable of reading the parameter data for commands on oracle stored procedures that are collected in packages. We can create a command, change the command type to StoredProcedure and enter a stored procedure or function name and it works fine (same functionality as simply drag'n'dropping the stored procedure or function from the server explorer to the designer). That works smoothly. However, when we enter a function name from a package, the name cannot be resolved. It works fine during runtime, when we have manually added the parameters (so there is no spelling problem with the names) - but the designer simply doesn't find the stored procedure or function. Is this a known problem? Are there any workarounds? What we're considering is creating temporary stored procedures (not in a package) to automatically get the parameters, and then manually changing the name so that it referes to the original function stored in a package. This is still easier than manually entering the parameters - but still it's rather cumbersome and time consuming... regards, david -- Auch das geht vorüber.

    - unclosed connections problem We have recently migrated a classic asp/sql server web site from windows server 2000 without the .net framework installed to windows server 2003. We seem to be finding that sql server is using up excessive amounts of RAM, much more than the old machine, even with the same amount of traffic. I suspect there may be a number of unclosed database connections in the legacy asp code and that windows 2003 is not shutting them down as quickly as with windows 2000. Does this sound plausible and if so is their any temporary work around to solve the problem. (It may take some time to correct all the code problems) Scott Tag: Returning Multiple Resultsets with Jet Tag: 72140

    - OUT NUMBER Parameters with Microsoft OLE DB Provider for Oracle => Hi Group, we're experiencing a very weird problem with the Microsoft OLE DB Provider for Oracle. We're using the version shipped with Visual Studio.NEt 2003. When we have any OUT parameter of type NUMBER, we get OCI-22060 (Argument [2] ist eine ungültige oder nicht initialisierte Zahl). This also happens when calling a function, where RETURN_VALUE is declared as NUMBER. OUT parameters as VARCHAR2 work fine, whenever we switch to NUMBER, the problem occurs. We're simply drag'n'dropping the command (stored procedure) from the server explorer. Could it be we're doing anything wrong? Or is this a bug in the provider? If so, are there any workaround or fixes available? regards, david -- Auch das geht vorüber.

    - Using IN keyword in data adapter. Hello all - I've searched high and low to an answer to my question so I'm posting here as my last option I'm trying to use the IN keyword in my WHERE clause of the data adapter to gather all IDs, separating them with commas, but I get an error that states that it could not convert a varchar value (due to the potential comma being there I needed to) to an int (which is what the ID field is defined as). Does anybody know what I can do to get around this issue or is there something I'm doing wrong?

    - DataSets, DataAdapters and bad design Does anyone else think the whole design of ADO.NET is a piece of ****? The DataSet is basically a mini, in-memory database. Heavy, tough to move data in and out of the database (@@Identity issues?). I've been developing desktop, web and n-tier applications for over 10 years and have never had a need for anything like it. Or do I just not get it? What am I missing? It seems to me all you need is a DataReader, a Command object, and a well designed data access layer. What do you need a DataSet/DataAdapter for?

    - SqlDataAdapter and finalization Hello all, I had some code that forgot (or should I say I forgot) to call Dispose on a SqlDataAdapter, so I thought it will be okay since SqlDataAdapter inherits via Component so the inherited Dispose/Finalize pattern would be picked up. However, after poking around with a decompiler I notice that within the constructor of SqlDataAdapter the call to GC.SuppressFinalize() is made so because my code forgot to call Dispose, the cleanup code will never be called via the overriden Finalizer in Component. Does anyone haveany thoughts on the rationale behind the SqlDataAdpater choosing to call GC.SuppressFinalize() in its constructor. Colin Tag: Returning Multiple Resultsets with Jet Tag: 72084

    - newbie, converting from ado to ado.net --> datareader help needed. Hi, I am converted an existing vb6 web app to vb.net and have run into a bit of a problem with data access via ADO.NET. I am doing a full text search against a SQL Server 2000 DB, the SP that I call to do this returns multiple resultsets, therefore from the documentation I found that I would have to use the SqlDataReader in order to move from one resultset to another. However here lies the problem. After the SP is called in the vb6 version I used the recordsets "RecordCount" method to create a large enough array to do some additional processing (don't ask). But I can no longer do this with the datareader because you read one row at a time. So my problem is how do I find out how many records are in the current resultset when using a datareader? As you can imagine the search SP is not trivial and repeating the query twice just so I can find out the recordcounts is not acceptable. My first guess at a solution would be to use an ArrayList and then just call it's .Add method then I wouldn't need to worry about array size. Any other suggestions welcome.

    - object model - dataset, dataadapter, datatable Hello All, Could you guys help me understand the ado.net object model ? This is what I think, correct me if I am wrong * DatAdapater acts as a bridge to bring in/send out data to database * Dataset is in-memory cache, disconnected from db, doesnt talk to db directly * DataTable could be a part of dataset. could multiple table from a common datasource be a part of same dataset ? * How to add multiple tables to same dataset, using same datasource ? * A separate dataadapter is needed, for each SELECT/Stored proc, which will bring in data to dataset Can a single dataadapter be used for multiple tables added to the same dataset having common source ? I am somehow confused & thinking that there has to be 1 dataadapater for each SELECT querying diff tables Regards Kalpesh Tag: Returning Multiple Resultsets with Jet Tag: 72067

    - Handling exception inside SQL Server stored procedure & return custmised message Hi friends, I am observing a pretty strange behavior when i try executing stored procedure using C# code. This is explained below: I have a table in which I have some constraints defined like unique, foreign key, check, etc. I have created a stored procedure to insert a record in this table. In this procedure, i am doing explicit exception handling. Say if there is any constraint getting violated during insert operation then I am catching the @@Error value in my locally declared variable @ErrorCode and if it's not equal to zero, then I am returning a customised error message via a output parameter declared in the procedure body, plus I am returning the actual database error code to the calling program by direct return @ErrorCode statement. Now when I execute this procedure with some dummy test values using a SQL Query Analyzer, it gives me perfect result. Now when I try to execute the same procedure from C#- ADO.NET code, with fresh values (which is not violating any constraints), it gives me perfect result. But the moment I test it with any values which violates the database constraint, exception message is displayed directly on the screen. As such, as per the logic implemented in stored procedure, the constraint violation message shouldn't be thrown by the C# code directly on the screen. I am just surprised to see this strange behavior. I am sure you have a reason for this strange behavior, plus an alternative way to do the same.

    - stored procedure and crystal reports for VS .Net I'm trying to get the results from a stored procedure into a crystal report in VS .Net. The stored procedure has one input parameter (date). When ever I create a new crystal report and set the database datasource to the stored procedure and then try to add a chart, it gives me an error about 'Convert' native error: 156. This error I guess has to do with maybe the Date input parameter not being specified? I'm not sure. Is there any real step by step examples of how to create a crystal report in VS .Net from a stored procedure data source? On a another note, is it possible to execute and get the results of a stored procedure (that has one input parameter) and put it into a dataset? If so how?

    - PLEASE READ CAREFULLY MAKE MONEY FAST AND EASY HURRY!!!! Make Money Fast A little while back, I was browsing these newsgroups, just like you are now, and came across an article similar to this that said you could make thousands of dollars within weeks with only an initial investment of $6.00! So I thought," Yeah, right, this must be a scam", but like most of us, but I was curious, so I kept reading. Anyway, it said that you send $1.00 to each of the 6 names and address stated in the article. You then place your own name and address in the bottom of the list at #6, and post the article in at least 200 newsgroups. (There are thousands) No catch, that was it. The main difference between this system and others is that you have a mailing list of 6 instead of 5... This means that your average gain will be app. 15 times higher!!! So after thinking it over, and talking to a few people first, I thought about trying it. I figured what have I got to lose except 6 stamps and $6.00, right? Like most of us I was a little skeptical and a little worried about the legal aspects of it all. So I checked it out with the U.S. Post Office (1-800-725-2161) and they confirmed that it is indeed legal! Then I invested the measly $6.00.............plus postage Well GUESS WHAT!!... Within 7 days, I started getting money in the mail! I was shocked! I still figured it would end soon, and didn't give it another thought. But the money just kept coming in. In my first week, I made about $20.00 to $30.00 dollars. By the end of the second week I had made a total of over $1,000.00!!!!!! In the third week I had over $10,000.00 and it's still growing. This is now my fourth week and I have made a total of just over $42,000.00 and it's still coming in rapidly....... It's certainly worth $6.00, and 6 stamps, I spent more than that on the lottery!! Let me tell you how this works and most importantly, why it works.... also, make sure you print a copy of this article NOW, so you can get the information off of it as you need it. The process is very simple and consists of 3 easy steps STEP 1 Get 6 separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 6 US$1.00 bills (or equivalent in your local currency) and place ONE inside EACH of the 6 pieces of paper so the bill will not be seen through the envelope to prevent thievery. Next, place one paper in each of the 6 envelopes and seal them. You should now have 6 sealed envelopes, each with a piece of paper stating the above phrase, your name and address, and a $1.00 bill. What you are doing is creating a service by this. THIS IS ABSOLUTELY LEGAL! Mail the 6 envelopes to the following Addresses: #1) J Alex Biley 69 Manningham St. Parkville, Vic 3052; Australi #2) Suranga Sampath 237/a Bell St. Coburg, Vic 3058; Australi #3) Greg Davidson 1370 South Madison Ave. Clearwater, Fl 3375 #4) J. Schlundt 190 Brookline St. Newton Ma 0245 #5) D. Hale Jr. 407 Edgewood Ave. Pittsburgh, Pa 1521 #6) Nimai Jaekley; 3311 Landon Dr. West Unit A; Bullhead City, A 8642 STEP 2 Now take the #1 name off the list that you see above, move the other names up (6 becomes 5, 5 becomes 4, etc...) and add YOUR Name as number 6 on the list. (Use your 'delete" key to remove name #1 and move all other names up. Then change numbers and add your name as #6) STEP 3 Change anything you need to, but try to keep this article as close to original as possible. Now, post your amended article to at least 200 newsgroups. (I think there is close to 24,000 groups) All you need is 200, but remember, the more you post, the more money you make! Don't know HOW to post in the newsgroups? Well do exactly the following: THAT'S IT! All you have to do is jump to different newsgroups and post away, after you get the hang of it, it will take about 30 seconds for each newsgroup! **REMEMBER, THE MORE NEWSGROUPS YOU POST IN, THE MORE MONEY YOU WILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF 200** That's it! You will begin receiving money from around the world within days! You may eventually want to rent a P.O. Box due to the large amount of mail you receive. If you wish to stay anonymous, you can invent a name to use, as long as the postman will deliver it. **JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT** Now the WHY part: Out of 200 postings, say I receive only 5 replies (a very low example). So then I made $5.00 with my name at #6 on the letter. Now, each of the 5 persons who just sent me $1.00 make the MINIMUM 200 postings, each with my name at #5 and only 5 persons respond to each of the original 5,that is another $25.00 for me, now those 25 each make 200 MINIMUM posts with my name at #4 and only 5 replies each, I will bring in an additional $125.00! Now, those 125 persons turn around and post the MINIMUM 200 with my name at #3 and only receive 5 replies each, I will make an additional $626.00! OK, now here is the fun part, each of those 625 persons post a MINIMUM 200 letters with my name at #2 and they each only receive 5 replies, that just made me $3,125.00!!! Those 3,125 persons will all deliver this message to 200 newsgroups with my name at #1 and if still 5 persons per 200 newsgroups react I will receive $15,625.00! With an original investment of only $6.00! AMAZING! And as I said 5 responses is actually VERY LOW! Average is probable 20 to 30! So lets put those figures at just 15 responses per person. Here is what you will make: at #6 $15.00 at #5 $225.00 at #4 $3,375.00 at #3 $50,625.00 at #2 $759,375.00 at #1 $11,390,625.00 When your name is no longer on the list, you just take the latest posting in the newsgroups, and send out another $6.00 to names on the list, putting your name at number 6 again. And start posting again. The thing to remember is, do you realize that thousands of people all over the world are joining the internet and reading these articles everyday, JUST LIKE YOU are now!! So can you afford $6.00 and see if it really works?? I think so... People have said, "what if the plan is played out and no one sends you the money? So what! What are the chances of that happening when there are tons of new honest users and new honest people who are joining the internet and newsgroups everyday and are willing to give it a try? Estimates are at 20,000 to 50,000 new users, everyday, with thousands of those joining the actual internet. Remember, play FAIRLY and HONESTLY and this will work. You just have to be honest. Make sure you print this article out RIGHT NOW, also. Try to keep a list of everyone that sends you money and always keep an eye on the newsgroups to make sure everyone is playing fairly. Remember, HONESTY IS THE BEST POLICY. You don't need to cheat the basic idea to make the money!! GOOD LUCK to all and please play fairly and reap the huge rewards from this, which is tons of extra CASH. TRUST ME IT DOES WORK! I am sure this will work out, try it and see.

    - calling a dataAdapter Update in DataTable.DataRowChanged Event At some part of my application I want to hide the idea of a cache (dataset) from my user, so went the user deletes a row using the data bound UI, which deletes the row from the corresponding data table, I want to make a call to commit the changes to database as well, so what I did is I registered an event handle for the DataRowChanged Event and tried to call DataSet.GetChanges. The problem is DataSet.GetChanges return null. Is is because the DataSet is still in edit mode when the DataRowChange event fires? So how can I commit data at the same time as it is deleted from the dataset apart from putting a separate 'commit' button? thx in adavance Tag: Returning Multiple Resultsets with Jet Tag: 72030

How is this typically implemented behind scenes. I want to build this functionality myself.

Given an XML file created from a DataSet using the WriteXML method, including the Schema, how would you then read that XML file into a dataset and then write the dataset to an Access Database table?

    - Windows Forms semi-connected data-access best practice I have looked around and have not found a best practice or pattern regarding the use of data in a semi-connected multi-user windows form application. What I have is this, a Windows Forms Client-Server application which ties in to Microsoft SQL Server 2000. Currently the application acquires data on clients from the database when it loads so that the end user can work on said data. When changes are made they are made to the dataset to track changes and properly manage new record creation. When the user exits, or clicks save, changes are submitted using a variety of DataAdapters to properly hierarchally update the data. I believe though that although this has worked for single-user systems, this is not the best practice for a multi-user system as data can become inconsistent as changes are made by each application. Would it be better to: * Transmit transacted changes immediately to the database once the DataSet can perform its constraint checks, rather than wait until the user clicks "Save" * Find or put together a means to constantly check for updates to actively changing and highly used tables (such as clients) and freshen the data as soon as is possible. I would rather this application be as connected as possible to the database server, and that updates be as real-time as possible. I have seen "some" examples of a semi-connected application using a web-service and performing some type of polling for connectivity however I do not wish to expose the business logic as a web service at this time. None of the examples explain how to manage a consistent state for real-time or pseudo-real-time data. -- Ron A.

    - *very* basic question about design of ado.net Sorry in advance for my ignorance. Any help would sure be appreciated. I'm writing a fairly simple application with VB.Net and am obviously a bit of a newbie. This application will be used by 1, 2 or at most 3 people concurrently and I'm using Access 2003 for my data source. We are not dealing with a large amount of data (5 or 6 tables, for a total of maybe 3,000 records - one table having the majority of that). This application is using a fairly simple form, but upon leaving certain text boxes, I want to fill in some data. For instance, I might have one field that is for a competition number - when I leave it, I want to populate a description. The next field might be a competitor number and when I leave it, I want to populate a field with the competitor name. Enough of the background - I created a module to open my connection and a function within that to handle my DataReader. In that module I have: Imports System.Data Imports System.data.oledb Imports System.Data.sqlclient Module Main Public strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=f:\mydatabase.mdb" Public cn As New OleDbConnection(strConn) Function ExecuteReader(ByVal sSQLString As String) As OleDb.OleDbDataReader Dim dr As OleDbDataReader Dim cmd As OleDbCommand = New OleDbCommand(sSQLString, cn) Try If cn.State = ConnectionState.Closed Then cn.Open() dr = cmd.ExecuteReader() cmd.Dispose() Catch ex As OleDbException MsgBox(ex.Message, MsgBoxStyle.Exclamation) End Try Return dr End Function End Module And that's pretty much it so far. In my main code I have: Private Sub txtCompNum_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtCompNum.LostFocus Dim dr As OleDbDataReader dr = ExecuteReader("SELECT * FROM competition where compnum = " & "'" & txtCompNum.Text & "'") While dr.Read txtDance.Text = dr.GetString(2) End While dr.Close() End Sub Private Sub txtCompetitor_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtCompetitor.Leave Dim dr As OleDbDataReader dr = ExecuteReader("SELECT * FROM dancer where cardnum = " & txtCompetitor.Text) While dr.Read txtName.Text = dr.GetString(3) & ", " & dr.GetString(4) End While dr.Close() cn.Close() End Sub These seem to work well and fast. But there are a few questions: 1. Is there a "right" way to structure creating the different components necessary to populate my form and if so, is mine along the right lines so far? 2. Should I use "Leave" or "Lost_Focus" for my text boxes? I used to use "Lost_Focus" with VB6, but was wondering if there was a difference or if one was preferred. 3. If the two datareaders above only return one record, is there some other reader I should use to improve performance? Any other suggestions would sure be appreciated. I'm a bit wet-behind-the-ears so I'd love some help. Thanks! Steve Tag: Returning Multiple Resultsets with Jet Tag: 71970

    - ADO.NET Bug re: Autoincrement Columns "Value ... is already present" VS2003 v7.1.3088 .NET v 1.1.4322 SQL Server 2000 Hi, I am getting these "Value is already present" errors occasionally on my autoincrement columns. I am not doing anything special here, just using the code that is generated by the Visual Studio designer. I have tried autoincrement seeds on the table of both 1 and 100, but it doesn't make any difference. Most of the time, it works, but every once in a while, I get this problem... usually when the table is "young" but not necessarily on the first inserts. I am 99% certain that SQL Server is not the source of the fault. The fault, I believe, is with the SQL generated by Visual Studio and/or the manner in which ADO.NET handles the merging of the INSERT results into the original table. If you look at the SQL statement generated by Visual Studio, you will see that it SELECTS the results of the insert. I believe that Visual Studio is immediately attempting to merge the results into the source dataset, so if there are still rows in the dataset waiting to be inserted and the IDENTITY result of the first insert happens to coinicide with the "Fake" ADO.NET identity in one of the pending insert rows, then ADO.NET throws an exception. This would be a bug in ADO.NET, in my opinion. I do not want to have to customize the INSERT statements for all of my SQL commands. This would be a lot of work, and also essentially renders the Visual Studio designer useless. My question is: Is there a known workaround for this problem? I have seen this suggested: http://groups.google.ca/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&selm=KQ5HdGMFDHA.2580%40cpmsftngxa06.phx.gbl ...but you would have to remember to repeat this step every time you regenerated the dataset, not good. The only other idea is temporarily turning off constraints during the insert... would it work? See code examples below... names have been changed to protect the identities of the innocent. FYI, the dataset is being generated by a client app, the data updates are done by an EnterpriseServices component (COM+). Otherwise, this is 100% plain-jane Visual Studio generated code. >>>>> Visual Studio's generated SQL statement <<<<<<< Me.SqlInsertCommand2.CommandText = "INSERT INTO X(Y_Id, Z_Id) VALUES (@Y_Id, @Z_Id); SELECT X_Id, Y_Id, Z_Id, FROM X WHERE (X_Id = @@IDENTITY)" >>>>> ERROR MESSAGE <<<<<<<< Column 'X_Id' is constrained to be unique.

    - Handling of a ConstraintException Hi. I got so much help out of the dotnet Groups, so I thought I'd share a little wisdom I found out. Forgive me if the solution I present is already well known (honestly, it is stupid simple) - But I found only questions like mine asked in the header, and no answers. Brief description of the problem: You load your tables using a dataadapter into your dataset. Tables are master/child, the dataset enforces the relation. Somehow, one of the masters got deleted - and the children are stranded. When enforcing the constraint, you get the exception. You want to find out, which child rows cause the trouble. The exception does not deliver this data in one of it's properties. Brief description of my solution: The data has been loaded fine already, so you can do the following (in the catch ex as ConstraintException-block): For each dr as DataRow in ChildTable if dr.GetParent is Nothing then dr.delete Next DataAdapter.Update(ChildTable) Dataset.EnforceConstraint = True Now the rows causing the trouble are gone, and the changes are put back to the database. In my solution, deleting the rows was the best idea - you might need to do something else, but once you know the rows, you can handle them as you like! After Enforcing the constraint yourself, your Dataset is ready to go, as if nothing ever happened to it! Bye, Ralf Tag: Returning Multiple Resultsets with Jet Tag: 71956

    - Restating -- Conditional SubQuery in WHERE. Hi All, I wasn't very clear before. I am trying to see if there is a way to have conditional subqueries in the WHERE part of an SQL statement. Generally I am trying to return rows matched to the subquery when there are rows returned by the subquery. No problem using IN. What I want is,, If there are no rows in the subquery returned, I want to see all rows in the outer select. In other words I would like to turn off this portion of the WHERE statement (or trick it to have no impact in the WHERE. EX/ Alter Procedure PrefProv @UserID VarChar(50), @Flag BIT SELECT Name, Address1, HCity FROM table1 WHERE table1.ID IN (SELECT Table1ID FROM dbo.table2 WHERE UserID = @UserID) AND Flag = @Flag The subquery will return Table1ID 's that match the UserID = @UserID, Then table1 columns where ID is in the list of Table1ID 's returned by the subquery AND if Flag = @Flag. If the table2 subquery returns no records I would like the statement to act like. SELECT Name, Address1, HCity FROM table1 WHERE Flag = @Flag In other words disable the portion of the WHERE which is related to the subquery. I have tried CASE but CASE doesn't want to work with IN. CASE works fine with =,<,> or LIKE. I have also looked at EXISTS but the examples in Books Online show equivalent IN statements. I could (and may have to) use IF..ELSE and change or leave out various WHERE terms but I have many variations and would make for a very complex PROC. Also if someone could explain EXISTS to me and how it may differ from IN I would appreciate it. From Books Online: The EXISTS keyword is important because often there is no alternative, nonsubquery formulation. Although some queries formulated with EXISTS cannot be expressed any other way, all queries that use IN or a comparison operator modified by ANY or ALL can be expressed with EXISTS.

Hi,

I was wondering if you can return multiple Resultsets with
Jet 4.0. I keep getting an error on the ; .

Dim sSql As String = "SELECT Full_Name FROM States WHERE
Country_ID = " & CountryID & " ORDER BY Full_Name;" _
& "SELECT * FROM Countries ORDER BY Name;"

Does this work with Jet 4.0?

Nope. JET is incapable of returning multiple resultsets.
