    - using go in a sql batch Hello, in SQL scripts I can use GO to force query analyzer to finalize the batch above. Before continuing with execution of code. This is needed i.e. when i add a new column before i can fill it. Is there an equivalent statement that can be used when hte script is loaded from file and executed with adonet (sqlclient) or do I have to split the script file?

    - System.Data.OracleClient Bug Hi all, There is a fix about System.Data.Oracleclient.OracleConnection object about not removing invalid connections from the pool in the following adress. http://support.microsoft.com/default.aspx?scid=kb;en-us;830173 I am facing the same problem. But i am confused about versions of oracleclient.dll. On the fix page, the version mentioned after the fix for framework 1.1 is 1.1.4322.2038 On the production machine that the application runs, version of the this dll is 1.1.4322.2312. so is it possible that same problem may appear on the future versions of the oracleclient.dll ? thanks.

    - Bad Uri Format In the docs this is used all over the place: new Uri("somefile.txt") but that throws an exception "Bad Uri Format". It works if you specify: new Uri("somefile.txt", UriKind.Relative) Is this a bug or how it is supposed to work? I thought Uri's were relative by default (though I have 'reflected' it yet).

    - SqlConnection.ClearPool as best practice on command timeout? If a timeout occurs on a SqlCommand while it is in the middle of executing a transaction contained withing a stored procedure (transaction is started in the stored procedure with BEGIN TRANS, as opposed to being started in the .Net application), database resources can stay locked even after the connection is closed when connection pooling is enabled. However, if SqlConnection.ClearPool is called prior to closing the connection, then the connection is discarded (not returned to the pool) when it is closed. This results in the transaction being rolled back, freeing the database resources. So it would seem that a 'best practice' would be to always call SqlConnection.ClearPool whenver a command timeout occurs. I haven't seen any discussion of this anywhere. Was wondering what other people might think about doing an unconditional ClearPool under these circumstances. (It would be nice if there was some way to detect if there was an open transaction on a connection, in the case where the transaction was started from within a stored procedure, but don't believe this is the case. That way, the ClearPool could be called only when there was actually an open transaction that needed to be rolled back.) Tag: Enum redefinition when upgrading to VS2008 Tag: 144487

    - retrieving individual row counts from a stored procedure (this is related to my previous post yesterday but I think i'm asking a distinct question so it's a new post) say I have a stored procedure that does 3 updates: update table1 set .... where ... update table2 set .... where ... update table3 set .... where ... if I execute this using management studio, the output window shows (for instance): (1 row(s) affected) (5 row(s) affected) (10 row(s) affected) however, if I execute it in ado.net using ExecuteReader, I just get a single resultset with 16 rows affected. RxecuteNonQuery and ExecuteScalar don't help either. is there any way at all to get the individual row counts from ado.net? Thanks Andy Tag: Enum redefinition when upgrading to VS2008 Tag: 144465

    - How Do I setup a RowChangedEvent in a Typed DataSet Greetings, I have a strongly typed dataset and when I write the identity column to the database, I set it and retrieve it. This works fine. Now I want an event to trigger for each record that is set and retrieved from the DataSet to update the children of the DataSet with the new identity column. The DataSet Created two Classes for the Products Class called ProductsRowChangeEvent - and - ProductsRowChangeEventHandler which will probably do the trick if I knew how to use them, or could find some documentation on these two Classes.

    - returned row count when a trigger is invoked Hi, in my .net application, I am using IDbCommand.ExecuteNonQuery() to update a single row. as a matter of good programming practice, I check the "rows affected" return value to verify that only 1 row was updated. the problem comes if there is a database trigger on the table which does further updates. it seems to add the number of rows updated by the trigger to the rows affected by the original SQL and return me the total. I would like to ignore the count of rows updated by the trigger. is there any way I can either (a) code the trigger so that it doesn't affect the value returned to my program; or (b) get more information about how the "rows updated" count is comprised (to distinguish between rows affected by the original SQL and those affected by the trigger) Many thanks in advance for any clues Andy Tag: Enum redefinition when upgrading to VS2008 Tag: 144445

    - MDAC required Hi, I have an application (that I wrote) that use ADO.NET to access an JET (Access) database. My application was working fine, until I installed and uninstalled a trial version of Microsoft Office 2007. I don't know if it was working between the installation and uninstallation of office, because I didn't tried it. Now, it does not work anymore. I get this error (translated from french) : The .Net Framework Date Providers requires Microsoft Data Access Components(MDAC). Install Microsoft Data Access Components (MDAC)2.6 or later. Of course I tried to install MDAC 2.8 SP1, but it says I don't need it since my OS already have. So I looked on the web and found a way to install it anyway. The installation seemed to work, but it did not resolve the problem. I uninstalled en re-installed the .Net Framework. It did not helped either. So the situation is I _seem_ to have a valid installation of MDAC 2.8, but my dotnet 2.0 application keep complaining that it need me to install MDAC 2.6 or higher. What should I try next? In advance, thanks for your help. Mathieu Pagé Tag: Enum redefinition when upgrading to VS2008 Tag: 144442

    - Getting Byte[] data with MySQL -Cast(... AS BINARY) Hi, I am trying to get (and transfer over ASP.NET) some encrypted data from some MySQL fields. Since the data contains many unicode characters, I tried to get the data as a series of ASCII values, transfer those numeric values over ASP.NET. I had no problem doing this on my local computer, by getting the field with "cast(field as BINARY)" so that on ASP.NET I have a byte[] array.Then send every field of array over ASP.Net. However when I upload application to remote server, "cast(field as BINARY)" returns field data as String type. I have tried many ways to convert this string data to byte array, however data always become corrupted. So I have to get data as a byte array directly from MySQL. As I've said, I had no problem doing this on my local computer, however, on my local computer I was connecting to same computer using same driver (MySQL Odbc 3.51), so when I upload the ASP.NET page to remote server, ONLY thing that is changing is location and -maybe- ASP.NET version (I am sure both are ASP.NET 2 , maybe different builds) So, the bottom line is: I am trying to get MySQL data as byte[] type, on local web server I have no problem, on remote web server (connecting to SAME MySQL Server) I get data as String, instead of Byte[]. How can I achieve same result on remote server? Tag: Enum redefinition when upgrading to VS2008 Tag: 144438

    - SQLHelper & DataGridView I am trying to populate a MS DataGridView with Stored Procedure using SQLHelper. I am connecting to a FireBird database. I'm also using SQLHelper for FireBird. For all intents and purposes the code is the same for SQL Server. The DataSource property is set to use the SP and I have changed the ObjectType to int to reflect the ParameterType. When I supply the parameter and PreviewData, the SP executes as expected. However, when I run the program the DataGridView displays with the correct column header text but the data is missing. Sample code follows: FbParameter[] rsParms = new FbParameter[3]; // @ID Input Parameter rsParms[0] = new FbParameter("@ID", FbDbType.Integer, 0); rsParms[0].Direction = ParameterDirection.Input; rsParms[0].Value = inComingID; //int value supplied by the user via the form // @NAME Output Parameter rsParms[1] = new FbParameter("@NAME", FbDbType.Integer); rsParms[1].Direction = ParameterDirection.Output; // @ADDRESS Output Parameter rsParms[2] = new FbParameter("@ADDRESS", FbDbType.Integer); rsParms[2].Direction = ParameterDirection.Output; SqlHelper.ExecuteReader(Properties.Settings.Default.dbConnection, CommandType.StoredProcedure, "SP_CONTACTS",rsParms); I am clueless.

    - datacolumn datetime from UTC to Localtime Hi, VB.net 2005 CLR 2.0 I have a dataset with a datatable...there is one datetime field, and about 30 double fields. The datetime field is in UTC Time, but my client application needs to see this in localtime. The datetime field is accurate to the millisecond... The data source is a flatfile (not a db) [tabbed delimited], thus, I can't easily use the functionality of a server to return the gernerated column I need (utc to local time) I'm using the ms text driver, and Schema.ini to get the data into my datatable, and this works fine. Is there a way to add a datacolumn to my datatable (type datetime) that uses an expression and convert the utc time in the orig field to localtime in a new field? thanks, george jetson On the side, against sqlserver 2000 in ado.net, I can't seem to write a query against a view to return some rows when the timestamp has millisecond resolution (When I don't use this resolution, it works) i.e.: SELECT myField from myTable where myTime = '3/6/2008 9:30:00' WORKS i.e.: SELECT myField from myTable where myTime = '3/6/2008 9:30:00.723' DOES NOT WORK -- thanks in advance, georgejetson Tag: Enum redefinition when upgrading to VS2008 Tag: 144410

    - Get Different values in gridview for Edit Btn (wrong CommandArgume I am at wits end trying to figure this out!! Basically i have a GridView in a UserControl. I assign the pk of the item bound to it via a LinkButton in a template. All works fine until i raise an event from the usercontrol, change the data from the calling aspx page and rebind it. By doing so, the LinkButton has the WRONG CommandArgument - to confuse things even further i tested by adding a button field that is bound to the same value -- the text output of this is correct, however the CommandArgument in the linkbutton is not - how is that even possible? Here is the buttonField and the LinkButton, both of which get diffrent values for pkContentPage <asp:ButtonField CommandName="Edit" DataTextField="pkContentPage" /> <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "pkContentPage") %>' CommandName="Edit" Text="Edit" </asp:LinkButton> Any help would be greatly appreciated Tag: Enum redefinition when upgrading to VS2008 Tag: 144406

    - Batch of Stored Procedures In our .Net 2.0 web service we need to insert/update data records into SQL Server 2005 that have been uploaded to us in XML documents. There could be anywhere from one to literally thousands of records in each uploaded transaction, and there are several dozen destination tables. Since performance is critical for this particular app, we were thinking of combining the stored procedure calls into configurable- sized batches using CommandType.Text and multiple concatenated EXEC statements, so we minimize database roundtrips as opposed to calling each SP individually in its own SqlCommand. Is this a good approach? One concern is that SQL Server would have to compile each and every batch since they will all be different, and the overhead involved in this could become significant. Is this really something to worry about, or not? Wouldn't a few batch compiles per transaction still be better than potentially thousands of roundtrips? Are there other problems with this approach? Of course we are planning to stress test to see how it actually responds, but I just wanted to get some opinions first in case someone has done this before and can give advice/recommendations/suggestions before we get too far into it.

    - ODBCCommandBuilder produces different UpdateCommand with Oracle using If I use a command that contains field name aliases, I get a different result for _cmdBldr.GetUpdateCommand().CommandText, depending on whether I am connected to SQL Server 2005 or Oracle 10g.

WHERE ((ID = ?) AND ((? = 1 AND PLANGROUP IS NULL) OR (PLANGROUP = ?)) AND ((? = 1 AND DESC_R IS NULL) OR (DESC_R = ?)))" When I run this for an Oracle connection the _da.Update(_dt); command generates an exception: "ERROR [42S22] [Oracle][ODBC][Ora]ORA-00904: "PG": invalid identifier" and _cmdBldr.GetUpdateCommand().CommandText returns: "UPDATE TABLEA SET ID = ?, PG = ?, DESC_R = ? WHERE ((ID = ?) AND ((? = 1 AND PG IS NULL) OR (PG = ?)) AND ((? = 1 AND DESC_R IS NULL) OR (DESC_R = ?)))" Note that in SQL Server, the original field name "PLANGROUP" is used in the UpdateCommand. In Oracle, the field name alias "PG" is used. Is there a way to force the command builder to create an update command with the orginal field name when using Oracle? Is there another approach I should be using, other than always creating my own update command from scratch for Oracle? Thanks. Tag: Enum redefinition when upgrading to VS2008 Tag: 144403

As I am filling both the master and details using vs 2005 generated dataset and data adapters, there are multiple connection open/close during the whole operation (one connection open/close per adapter fill). Is there a way to override the vs generated connection management code to open the connection only once at start, do all fills and then close the connection at the end, to speed up the whole fill process?

    - Wierd error on data set Occassionaly (and its rare, but i think there are repo steps to this, i just cant completely determin them, but here is what I figured out so far) I have a data set (say its called DS) I have three tables... call them people, peoplejunitem and item... peoplejunitem is a many to many junction table between people and items... well say I load one set of information about a person into the data set's tables... ok this person has items in the junction... say I alter the information in the junction but dont commit it to the database... now I go and load another person... but while loading the next person it clears the information in the junction table and the person table and replaces it with the 2nd person... ok I make changes and push the data back to the database... and boom error... zero rows updated when 1 was expected to be... well that one row updates was from the FIRST! person... even though I did a ds.table("PersonJunItems").rows.clear somehow it still thinks it has rows to push! why?! this happens randomly to me! I tested out the T-SQL statements like crazy and they are not at fault, they are return the correct response, but while watching the SQL Server profiler I saw the commands to update the pervious person going through on person 2 to the database... any ideas how to stop this or fix the problem? or anyone ever see anything similar to this? thanks!

    - Open file suddenly stops existing?! A file is successfully opened, partly read, and not closed, but suddenly it stops existing? How does Ado.Net accomplish this result? This seems to be a 100% repro on one file but 100% no problem on a different file. Again how does Ado.Net do this? // Sample dirName is C:\myDir and tableName is myFile1.csv or myFile2.csv. OleDbConnection connection = new OleDbConnection( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dirName + ";Extended Properties='Text;Extensions=asc,csv,tab,txt;" + "HDR=Yes;FMT=Delimited'"); connection.Open(); OleDbDataAdapter dataAdapter = new OleDbDataAdapter( "SELECT * FROM [" + tableName + "]", connection); DataTable dataTable = new DataTable(tableName); dataAdapter.FillSchema(dataTable, SchemaType.Source); DataColumnCollection dataColumns = dataTable.Columns; int fileColumnCount = dataColumns.Count; foreach (DataColumn dataColumn in dataColumns) { dataColumn.DataType = typeof(string); } // This works up to here. FillSchema worked. // The next call works on myFile1.csv but fails on myFile2.csv. dataAdapter.Fill(dataTable); // Exception: file does not exist. Wtf?

    - Returning the id of an inserted record I am writing an ASP.NET application, and am forced to use Access as my database. I need a way to return the id (which is an AutoNumber field in the table I am inserting into) of a record when I insert it. In SQL Server, I am able to use a statement like the following: INSERT INTO tablename (fieldnames) OUTPUT inserted.id VALUES(valuestoinsert) Take note of the OUTPUT inserted.id part of this statement. This returns the value of the field named 'id' for the record that was just inserted. Unfortunately, this technique does not work in Access. Is there any way to retrieve the id of the record that was just inserted when using Access? Any help would be appreciated.

    - How to solve DataSet Designer SQL errors? Hi there, I have writing easy to moderate SQL in the DataSet Designer and Query Builder, using a Jet 4.0 connection to an Access 2003 DB. I am running VB.NET 2005 sp1. As soon as I try to do anything more than the most trivial SQL (e.g. simple JOINs, more than 1 parameter other than in the WHERE clause, etc.), the Designer/Query Builder balks giving SQL parsing error messages. This means that the Fill, GetData() is not set up properly and compiler errors prevent me from running my app. This is despite the fact that the SQL is perfectly fine (it runs in Access) and in some situations it is possible to 'trick' the Designer (ref. link below). Aside from the critical issue of my app not running, I am not able to leverage strongly typed DataSets, and all the useful commensurate objects (e.g. DataTable, data row). I have been promoting this approach within our development teams, but all these problems make significantly reduce confidence in using these objects and the Designer. Nor it is sensible to use a blend of approaches in my app (e.g. trivial SQL through strongly-typed DataSets and the rest explicitly written in code) from a software design/maintenance perspective. If this can't be solved, I'll look at dropping use of the Designer and going back to hand-coded SQL. Any and all feedback that provides solutions to this problem (e.g. is there an update/patch to the Designer?) would be appreciated. Thanks in advance, David Newsgroup posting "Dataset designer and complex Stored procedure" on microsoft.public.dotnet.framework.adonet http://groups.google.ca/group/microsoft.public.dotnet.framework.adonet/browse_thread/thread/9c0a1938b49329ea/68917fe53b75058c?lnk=st&q=%22dataset+designer%22+sql+error#68917fe53b75058c Tag: Enum redefinition when upgrading to VS2008 Tag: 144304

    - OleDbCommandBuilder insert query will not work? dataset to Access I am trying to take a very strangely delimited text file and put it into access. So far I was able to get the text file into a dataset and figured from there I could get it into access. I am trying to use the code below but the insert query(oledbcommandbuilder) just will not work. I am working with a blank access database and I am able to get the table and the field names in the database(with a primary key just set ot the first row). I just cannot get the rest of the data. I get an error that there is incorrect syntax in the insert query. Can someone please help! I've been all over the site reading a buch of different things and tried to just write inserts for each row but cannot get that to work either. Thank you! DataSet result = new DataSet(); ...get delimited file into dataset... OleDbConnection DB = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\\Conversions\\" + agencyid + "\\" + agencyid + ".mdb"); OleDbDataAdapter DataAdapter = new OleDbDataAdapter(); DataAdapter.SelectCommand = new OleDbCommand("SELECT * FROM " + TableName, DB); OleDbCommandBuilder CmdBuilder = new OleDbCommandBuilder(DataAdapter); DB.Open(); DataAdapter.FillSchema(result, SchemaType.Source, TableName); DataAdapter.InsertCommand = CmdBuilder.GetInsertCommand(); //I added the line above because the insert query did not show in the data adapter. //It now has: insert into tablename(fieldname1,fieldname2...) Values (?,?,?...) DataAdapter.Fill(result, TableName); DataAdapter.Update(result, TableName);//Fails here on the insert query syntax DB.Close(); Tag: Enum redefinition when upgrading to VS2008 Tag: 144295

    - ORA-01406: fetched column value was truncated Using data reader against one of my Oracle tables is crashing with following error: System.Data.OracleClient.OracleException: ORA-01406: fetched column value was truncated. This happens with Microsoft ADO driver to Oracle. Oracle ADO driver works just fine. Error happens only with some records (there are some pretty large columns in a table), but not other. I wonder if anyone has any insights to this issue â?? we donâ??t want to compile Oracle drivers into our base applications, because most of our customers are using SQL Server. Thanks in advance.

    - Need some advice on my Deployment Pkg Hello. Using XP Pro w/SP4 and VS 2003. I wrote my program with the connection string and the path for loading the Maps as follows: C:\MVB.NDbProJim\Ch7\ROE6AllRecords2\Maps. The Maps sub-directory containes all 116 Maps of the Lots and also the ROE6.mdb database. But when I deplay this app to my other PC it gets an error that this path is invalid so it cannot even load the database. Since the MSI installs this package to C:\Program Files\Microsoft\ROE6 I decided to have the Maps subdirectory relocated to this Path. I had to change (in my program) the Connection String and all the 116 paths for it to load the Maps but it now works just fine on the other PC. I must have missed something because it is unreasonable to have to keep the support files at the same location on my PC as the installer is going to use on the target PC. Any words of wisdom to get me straightened out? TIA, Jim Tag: Enum redefinition when upgrading to VS2008 Tag: 144279

I just finished upgrading to Visual Studio 2008. When I compiled for
the first time I got this error message which I didn't get in Visual
Studio 2002. As the error indicates the redefinition conflict is
between two ADO include files.

What is the recomended way to correct this???

Thanks, Neil
