I think this is enough code to make sense of what I'm doing, but if more is needed just let me know and I can post it up as well.in the inner loop after a match is found - but reverting the order of the 2 loops) - but leaving the complexity order to O(n^2). For more information, see Merging Data Set Contents and Handling Data Adapter Events. The following examples demonstrate how to perform updates to modified rows by explicitly setting the Private Sub Adapter Update(By Val connection String As String) Using connection As Sql Connection = New Sql Connection( _ connection String) Dim adapter As Sql Data Adapter = New Sql Data Adapter( _ "SELECT Category ID, Category Name FROM dbo. Update Command = New Sql Command( _ "UPDATE Categories SET Category Name = @Category Name " & _ "WHERE Category ID = @Category ID", connection) adapter. For example, Update might execute a DELETE statement, followed by an INSERT statement, and then another DELETE statement, due to the ordering of the rows in the Data Table.It should be noted that these statements are not performed as a batch process; each row is updated individually.An application can call the Get Changes method in situations where you must control the sequence of statement types (for example, INSERTs before UPDATEs).

When using Update, the order of execution is as follows: Each command associated with the Db Data Adapter usually has a parameters collection associated with it.Does the error message get stuck because it cannot find the boolean value 'false' ?the above compiled and executed without any errors, but absolutely nothing changed - although the SELECT statement returned the row belonging to the int Foo primary key value, it did not update the is Active column.NET application by specifying command syntax at design time and, where possible, through the use of stored procedures. For example, the following code ensures that the deleted rows of the table are processed first, then the updated rows, and then the inserted rows. You must explicitly set the commands before calling event and setting the Status to Skip Current Row. NVar Char, 15, "Category Name") Dim parameter As Sql Parameter = _ adapter.
