    - UpdateCommand doesn't work fine. Hello, I've implemented a control that works with a database oracle, with dataset and dataadapter. It works fine, inserts, delete, and update works fine when the sentence is like "update table set a=:1,b:1", but when the update is "update table set a=:1,b=:2 where c=:1", it says "Concurrency Infraction: Update Command affected 0 register" or "ORA-01722: Incorrect number". It makes the sentence dynamically the code is: If txt.isPrimaryKey Or txt.ConcurrencyField Then If Not primerw Then where &= " AND " Else primerw = False End If where &= txt.FieldName & " =:" & txt.FieldName Else If Not primerc Then strupdate &= "," Else primerc = False End If strupdate &= txt.FieldName & "=:" & txt.FieldName End If If param Is Nothing Then ReDim param(0) Else ReDim Preserve param(param.Length) End If param(nparams) = New OracleParameter param(nparams).ParameterName = ":" & txt.FieldName param(nparams).OracleDbType = txt.FieldType param(nparams).SourceColumn = txt.FieldName If txt.isPrimaryKey Or txt.ConcurrencyField Then param(nparams).SourceVersion = DataRowVersion.Original Else param(nparams).SourceVersion = DataRowVersion.Current End If nparams += 1 Thanks in advance Silvia.

    - DataTable.Select method in .NET 2.0 Hi, I have a problem with DataTable.Select method in Microsoft .NET 2.0. I have a ListBox control, with DataSource pointing to a DataTable "RolePermissions". ListBox has SelectionMode property set to "Multiple". I would like to enable User to Delete Multiple items with just one click. I am almost sure, that this worked in .NET 1.1. I have a DataTable with column "permissionID" of type uniqueidentifier Here is my Code: // We will concatenate selected Guid's into one string StringBuilder sbItemsSelected = new StringBuilder(); // for every Item .... foreach (ListItem item in lbRolePermissions.Items) { // ... which is selected... if (item.Selected == true) { // ...we add selected ID, and space after it sbItemsSelected.Append("'"); sbItemsSelected.Append(item.Value); sbItemsSelected.Append("' "); } } /// We now have list of ID's, separated with spaces (with space at he end) string selectedItems = sbItemsSelected.ToString(); // remove last space selectedItems = selectedItems.Trim(); // insert commas instead of spaces selectedItems = selectedItems.Replace(" ", ","); // get the table, to handle data DataTable dtRolePermissions = Session["RolePermissions"] as DataTable; /// select rows, which are of interest to us ******************************************************************** DataRow[] drsRolePermissions = dtRolePermissions.Select("permissionID IN (" + selectedItems + ")"); ********************************************************************* /// delete them foreach (DataRow drRolePer in drsRolePermissions) { drRolePer.Delete(); } /// save new Table in Session variable Session["RolePermissions"] = dtRolePermissions; // bind the Table again lbRolePermissions.DataSource = dtRolePermissions; lbRolePermissions.DataBind(); The line inside "stars" is line, in which an exception occurs, the exception Message is: "Cannot perform '=' operation on System.Guid and System.String." I thought, that exception can occur because the Items in listBox are filtered with an expression, but that would be stupid of Microsoft not to let such operations. I am confused.... this really worked in .NET 1.1 I used it a lot in previous applications.... Is there some explanation to this fact ? ( apart from saying, that this is a bug ;-) ) Thank You in advance for help, maciu Tag: no value given for one or more required parameters - error Tag: 120024

    - Writing back data (Update) Hello, I have created a connection of a Siebel Database (or to be more specific Sybase SQL Anyware), and I am able to retrieve data and view it contents (Tables, Views Stored Procs) using odbc from ADO.NET. The problem I am having is trying to Update a table. It does not appear that I have permission or there is some other type of commands I should be using besides SQL statements. I really need information on writing data back to this database. Any information would be greatly appreciated. If necessary you will be able to VPN onto the computer to accomplish this. I would also be interested in a referral or consultant. Siebel has been no help, especially since Oracle has agreed to purchase them. Thrid party drivers are ok to, providing they do not require individual lisences for each computer that is using it.

    - Odd Behavior Copying VarBinary Data I'm copying the content from one DataTable to another. Both tables have a SQL column of type VarBinary. The data is actually copied this way. DataRow[Column] = DataRow[Column]; Would this method cause a problem with VarBinary data types? The problem I'm seeing is that the data seems to be duplicated. So, if the both rows contained the value "1 2 3" after the copy I'm seeing a value of "1 1 2 2 3 3" in the row where the data was copied to. Any thoughts ideas are appreciated.

Any ideas on how I can do this? I only know how to pull data from different tables using ONE connection. I have data in a completely different connection that I need to pull from. This is what I currently have: Connection.Open(); myDataAdapter = new OracleDataAdapter(); myDataAdapter.SelectCommand = new OracleCommand( query, base.Connection ); myDataSet = new DataSet(); myDataAdapter.Fill( myDataSet ); return myDataSet; This fills my dataset using the query and only one connection. I don't want to have to pass connection strings to the method that does this. Any ideas would be greatly appreciated!

    - Filtering question with related tables Hi guys, I've been struggling with this one for a while. I have a typed dataset. It has two tables inside of it; Resources and EmployeeMaster. Both EmployeeMaster and Resources have a column called "EmpID", an int, which is also both of their primary keys. This is the relationship between the two, and is present in the dataset. EmployeeMaster has detailed data about employees such as full name, address, email, etc. Resources is a table that I created that is used to determine which employees are using a program I am writing right now, and what their security level is. That column is of type int called "UserType". So this is all set up, my dataset is populating nicely with every row from both tables, everything seems to be set. Now, what I want to do is populate a listbox on a C# Windows.Forms app with employee names (stored only in EmployeeMaster) of only those employees who have a UserType (stored only in Resources) of 5. The equivalent SQL for this is simple. "SELECT emp.LastName FROM EmployeeMaster emp, Resources r WHERE r.UserType = 5" I can't figure out how to get the equivalent of this to work in my typed DataSet so I can databind it to my listbox. I looked at DataViews, but couldn't find any decent examples of the RowFilter that was filtering on a child table. I did find one page that said there's a "[child]" keyword that should be put in there, but I couldn't figure that out. I also looked at DataViewManagers, but hit a dead end on that one as well. Can one of you gurus give me a little guidance, please? I feel silly asking what's probably a really simple question, but I've scoured the net for hours and haven't found anything.

    - creating an xsd through xsd designer - xml format Hi all, I need some help: I have a DataSet object created by the .NET "xsd designer".

I put "Table1" into "Table" when I did that, but nothing happened. Is there a way to force a selected format on the XML I generate from the data in such a DataSet, or do I have to create the whole thing by code? Thanks!

    - Is there an XMLDataAdapter? I have two, dynamic XML files that contain data. My customer insists on using XML for a number of quite valid reasons. Being new (read naive) to XML, I thought there might be some form of SELECT statement that could be used with XML files. A number of books have referred me to the .NET SDK. However, I can't seem to find what I need. Is there a data adapter for XML? If so, where might it be documented? If not, must I program my own queries against the contents of various dataset tables (read by <data-set>.ReadXML)? I must stay within the Microsoft provided .NET framework and not purchase software from another vender. I also must assume that the user will have neither SQL nor Access available.

    - Update Multiple table using Dataset Hi, I have an issue in updating the Primary Key in the Parent table. I have set of three tables (Database SQL2000, VB.NET), where A is related to B and B is related to C. I have written a stored procedure which returns all the records in these tables and fill up a single DataSet. All these table have primary key which is an Identity Column. The dataset then populates the three grids in the client application. The users can add/update/delete the values in all the three tables and there is single save button to do the updates. I am code I have created DataRelation between table A,B and C. Also when I add a new add to the child table, I set the parent row as well. All these is working fine. I am using the example as described in the CodeProject article http://www.codeproject.com/cs/database/relationaladonet.asp?df=100&forumid=14883 But my problem here is when I add a row in the Parent table say A and then add new rows in the child table B. The new generated ID in the Parent table is not propagated to the rows in the child table. I am using RowUpdated event to capture get the latest ID returned from the stored procedure as output parameter. I use the latest ID to update the datatable. When I debug the application, I can retrieve the new ID in the RowUpdated event and set it back to the datarow: e.Row.Item("ColumnName") = newID. e.Row.AcceptChanges() But these changes are not seen in the dataset. It still has same old ID but in the DEBUG mode the e.row has the new value. Moreover, its an issue because the event arguments are passed as Byval and not as ByRef. i.e. I am not getting the actual reference to the DataRow. Has anybody faced this problems before?

    - Fill table in dataset with query and then add columns? I'm filling up a dataset table with a database query. Then I'm binding the dataset to an ASP.Net asp:DataGrid. However, some derived columns have values that are too complicated to fill out in the SELECT statement in the query. Can one add additional columns to a dataset after initially creating a dataset with a database query? What I want to do is to fill up the dataset with a query, create additional columns (unless I can/should do that in the SELECT list?), loop thru the dataset and on each row do some logic to decide how to fill out the derived columns. The derived columns can all be text. I do not need to do updates on this table back into the database. Is this a reasonable approach?

    - Fill related tables in dataset with one query? Thought this would be simple, but apparently its not. I have a strongly-typed dataset with tables that have relations set in the DataSet designer. I've been stymied when attempting to fill this dataset using a join query. Without TableMappings, nothing is filled in the dataset. I can't use table mappings, however, because it won't allow me to split one result set among four different tables. I can create a tablemapping for each table in the dataset, but the "source table" is the same in each one--the result set. No two table mappings can have the same source table, so it fails. If I was grabbing all data, it wouldn't be such a problem, as I could fill each table in turn. However, I'm performing a search at the same time, which means only relevant data is returned. Pulling it all down and then sorting through everything is not feasable, since the database could hypothetically contain millions of rows. What should I do? Use a DataReader and fill the dataset manually? TIA. Tag: no value given for one or more required parameters - error Tag: 119916

    - Copy a table using ADO.Net OK, I think the answer is no, but I need to ask. I have a table structure defined in my Access database (SQL Server is not available), I would like to take that table and create a new table with a unique name. Can I do this using ADO.NET?

    - Adding deleted rows back to a DataTable I'm trying to add rows marked as deleted back into their parent DataRowCollection by using DataRowCollection.Add. The behavior I was expecting was having the DataRowState switch back to it's last value before the delete, i.e. Unchanged->Deleted->Unchanged, Modified->Deleted->Modified, etc. Instead I get an ArgumentException with the message "This row already belongs to this table." Obviously the row does belong to the table, however it is not currently part of it's row collection. How would I go about implementing this? I know I can use RejectChanges but that will revert the state back to the last Original, which will undo any field changes as well. All I want to do is undo the last Delete action. I was considering adding a duplicate new row and loading the deleted row's values into it, but that might result in constraint violations when running the related stored procedures against the data source. Thanks in advance. Tag: no value given for one or more required parameters - error Tag: 119893

    - Hierarchical search of tree flattened to dataset--advise pls I have a search problem that I'm seeking some advice in. I'm dealing with the need to search node names in a tree structure that is flattened into a database table (I have no say over the design, just over how to search). The tree consists of nodes that represent rooms, cabinets in each room, drawers in each cabinet, etc. The flattened representation is as what you would expect--each data row has a column representing the room, cabinet, drawer, etc. When I search this data, I need to do it in a hierarchical fashion--I look at the first room, then the first cabinet in that room, then the first drawer in that cabinet, etc. If I search the dataset linearly, I end up showing the same hit multiple times (if I hit on the room name, once I finish showing hits on that row, I encounter the room again the next row). I could, once a hit is found, move vertically down the column in the dataset, erasing all names that match, but that isn't easily done without performing multiple checks to make sure I'm still in the same branch of the tree. Any hints on a better way to perform this search would be appreciated. I could convert the data to xml and use xpath, or create a normalized dataset and fill it appropriately, but I'm not sure this will ease the search later. Thanks.

    - SQL Server Raiserror and .NET SqlDataAdapter Running SQL Server 2000 SP4 and .NET Framework 1.1.43322 SP1 I have a trigger that does some work and then, when it decides there is a problem does: if @ErrMsg is not null BEGIN RAISERROR (50001,16,1, 'AssetConfig', 'AssetKey/Site', @ErrMsg) ROLLBACK transaction In my Windows Forms application I have try { SqlTransaction sqlTrans = â?¦.BeginTransaction(); Update several tables, including the one with the trigger sqlTrans.Commit(); } catch (SqlException e) { sqlTrans.Rollback(); } When the trigger raises the error, I do not get the @ErrMsg because the SqlDataAdapter does not trap the error. Instead, I get System.InvalidOperationException: This SqlTransaction has completed; it is no longer usable. at System.Data.SqlClient.SqlTransaction.Rollback() at the Rollback statement. This is because the Commit threw this SqlException Message # 3902 "The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION." What I WANT is to have the SqlDataAdapter.Update throw the error that I have specified, just as it would do if, for example, a primary or foreign key had been violated. Then the catch block would do the rollback and handle the error. I tried taking the Rollback out of the trigger, but then I got no message, no error, and the database was updated with bad data. What is the secret to making SQL Server Raiserror work with the Framework to return a meaningful error? Tag: no value given for one or more required parameters - error Tag: 119889

    - vs2k5 Beta2 'Code Analysis' returns warnings on generated code I built a simple Data Access Layer with the Visual Studio 2005 DataSet Designer using the wizard. All who I have talked to who use it, articles I haver read by those who use it speak very highly about the quality of code that vs2005 creates. Before adding any code of my own I ran "Code Analysis" (from debug menu) against the code and got (no errors but) 90 warnings! I know nothing about the "Code Analysis" and can find nothing in the help. Some of the warnings are just good suggestions that the user should consider based on best coding practice and the users intension for the code such as; Warning 4 CA2210 : Microsoft.Design : Sign 'NorthwindDataAccess' with a strong name key. 1 Other warnings point out things I think the Wizard should have handled; Warning 42 CA1804 : Microsoft.Performance : EmployeesTableAdapter.GetData(Nullable`1<System.Int32>):EmployeesDataTable declares a local, 'GetData', of type NorthwindDataAccess.EmployeeDataSet+EmployeesDataTable, which is never used or is only assigned to.

    - Concurrency management in XML Files Hi, I was wondering how it is possible to manage optimistic concurrency in XML files. Indeed, i store my data in xml files in an asp.net application. My data access layers accepts custom entities, and then uses dataset.WriteXml() to write the new data. The problem is that this way of doing erases all file content, and writes the content of the dataset. If a user wrote his changes just before we write ours his changes are lost. Is there a simple way to manage optimistic concurrency, like what we can do with a DataAdpter with SQL databases?

    - Some newbie questions Hi All Wondering if someone might have a few seconds to clear up some newbie queries I have with VB.NET and ADO.NET. I know their are limitless situations that require different approaches but would love to know some of the fundementals as a place to start. Have been through quite a few examples but are unsure about the following. 1. For a simple database with a couple of tables do you create a dataadapter for each table and then create a dataset that includes each of these tables? 2. Do you use the same adapters and datasets througout the application on different forms? If so how do you make them available to the other forms if you have used the wizard to create them? 3. Is it best to reference rows/records by ID number in the table or the row index? 4. Should you link tables in the database using views/queries in the database or by creating a separate datatable in the dataset that joins the tables from the database? 5. Any other advice on best practices for learing this stuff. Appreciate any assistance. ilr Tag: no value given for one or more required parameters - error Tag: 119858

    - Datagrid forecolor from dataview. Hi, How do I associate a column in the dataview with a color property of datagrid forecolor, more specifically a particular cells forecolor. I'm associating a dataview with the datagrid and the values are showing OK. But I want the fore color of a cell being set on specific condition. I'm thinking of adding a new column to the table which has an expression to determine the color. And if this is associated with the cell fore color, it should work great as I just need to keep on updating the data. I tried but couldn't find a way to do this. Any help would be of great use.

    - Modeless Form Lose Accelerator and Tabbing Keys All, I am using COM Interop with C# to display a modeless form via a COM call from an application written in Visual studio C++ 6.0. I can display the form as modeless however the accelerator and tab keys do not work. Interestingly, if the form is modal the accelerator and tab keys work properly. Also if the same form is launched from a C# appication (not using COM) the forms accelerator and tab keys work properly. The form is a Class library (DLL) that has a COM interface. There is a COM method that calls .Show() for the form. Does anyone know how to get the accelerator and tab keys to work when calling the form through COM?

    - Help with using DataView to insert Record..Please! I'm new to ado.net/asp.net and have been on a crash course these last few days. I've been stuck on this current problem for over a day and it seems pretty simple, but I can't get it to work. I'd like to create a data view from a data table, insert a record into that data view and have it inserted back into the actual database (Access 2000). Following tutorials online, I've been able to use a dataadapter to connect to the database, then using a datatable, insert new rows and have them inserted in the actual database. But when it comes to doing that same functionality via a dataview, I've had no luck. Here is the code I've been using. It generates no errors, and a new row is added to the underlying datatable, but nothing is ever sent back to the database. I think it might have something to do with the myAdpater.InsertCommand code (are these used the same way in DataViews as in DataTables?). Thanks in advance for any advice. Public Sub editLevelProgressFromView() 'Objects used to connect/read from database Dim cs As ConnectionStringSettings Dim myConnection As OleDbConnection Dim myAdapter As OleDbDataAdapter Dim myTable As DataTable Dim myView As DataView Dim myRow As DataRowView Dim sqlStr As String cs = ConfigurationManager.ConnectionStrings("strConn") myConnection = New OleDbConnection(cs.ConnectionString) sqlStr = "Select * from tblTest" myAdapter = New OleDbDataAdapter(sqlStr, myConnection) 'Set up insert commands for use on myAdapter.Update method myAdapter.InsertCommand = New OleDbCommand("INSERT INTO tblTest (c_name, c_number) VALUES(?, ?)", myConnection) myAdapter.InsertCommand.Parameters.Add("@c_name", OleDbType.VarChar, 15, "c_name") myAdapter.InsertCommand.Parameters.Add("@c_number", OleDbType.VarChar, 30, "c_number") 'Fill Table and create View myTable = New DataTable() myAdapter.Fill(myTable) myView = myTable.DefaultView 'Add Row to myView, insert data via BeginEdit and EndEdit methods myRow = myView.AddNew() myRow.BeginEdit() myRow("c_name") = "testName" myRow("c_number") = "testNumber" myRow.EndEdit() 'Accept changes in table from view myTable.AcceptChanges() 'Commint changes to database (does not work, but no error thrown) myAdapter.Update(myTable) End Sub Tag: no value given for one or more required parameters - error Tag: 119827

    - Confused about the DataAdapter I'm trying to learn/use ADO.Net and am puzzled by the DataAdapter. It has a TableMappings property which is a collection of mappings from the source into the DataSet. This implies that the DataAdapter can retrieve many tables from a source and store each in a single DataSet. But it only has a single SelectCommand so Fill() will only return single result set. I want to read 4 tables out of an access db. Do I need to create 4 DataAdapters to do it? Confused Tag: no value given for one or more required parameters - error Tag: 119811

    - Optimistic Concurrency and TimeStamp Hi, I would like to implement optimistic concurrency where I retrieve the timestamp of a record in a table with a stored procedure and save the timestamp value into a vb.net variable. This represents the original timestamp for the record. When a user updates the record, I would like to pass the original timestamp to a stored procedure that performs the update to ensure the record has not been changed by another user. The problem is, how do I store the original timestamp value from SQL Server 2000 in vb.net? I have tried: Dim OrigTstamp() as Byte I can assign an incoming timestamp to a byte array but I'm not certain if anything is there. I then have great difficulty passing the OrigTstamp() to the update stored procedure. -- Thanks, Scott H. Tag: no value given for one or more required parameters - error Tag: 119806

Hi all,

Why am I getting a 'no value given for one or more required parameters' error
when I try to fill the dataset. Below is the code I'm using and I'm getting
the error on the DASOURCE.FILL(DSSOURCE, "FIELDS"); part of the code.
objSourceConn is fine. Can anyone help?
Thank you.

string selectFromSource;
selectFromSource = "SELECT * FROM Fields WHERE ['Label name'] = '" +
drDistinctSource["Label name"].ToString() + "'";
OleDbDataAdapter daSource = new OleDbDataAdapter(selectFromSource,
objSourceConn);
DataSet dsSource = new DataSet();
daSource.Fill(dsSource, "Fields");
