Oracle DataSet with multiple tables

I have to do some major changes to an Oracle database; adding rows that require constraints to other tables.  Therefore I need the other tables in my dataset.

I can't get multiple resultsets to work.

Here's the code:


Dim otblPerson As New DataTable
Dim oDataRow As DataRow
Dim oDataSet As New DataSet("Pathlore")
Dim otblLUT_PERSON_XSELFHID As New DataTable
Dim daLUT_PERSON_XSELFHID As New OracleDataAdapter

daLUT_PERSON_XSELFHID.SelectCommand = New OracleCommand
daLUT_PERSON_XSELFHID.SelectCommand.Connection = oConn
daLUT_PERSON_XSELFHID.MissingSchemaAction = MissingSchemaAction.AddWithKey

Dim otblLUT_PERSON_YINACTIVE As New DataTable
Dim daLUT_PERSON_YINACTIVE As New OracleDataAdapter
daLUT_PERSON_YINACTIVE.SelectCommand = New OracleCommand
daLUT_PERSON_YINACTIVE.SelectCommand.Connection = oConn
daLUT_PERSON_YINACTIVE.MissingSchemaAction = MissingSchemaAction.AddWithKey

otblLUT_PERSON_YINACTIVE.TableName = "LUT_PERSON_YINACTIVE"
oDataSet.Tables.Add(otblLUT_PERSON_YINACTIVE)
otblLUT_PERSON_XSELFHID.TableName = "LUT_PERSON_XSELFHID"
oDataSet.Tables.Add(otblLUT_PERSON_XSELFHID)

daLUT_PERSON_YINACTIVE.SelectCommand.CommandText = "select * from UT_PERSON_YINACTIVE" & vbCrLf & "select * from LUT_PERSON_XSELFHID"

Try
daLUT_PERSON_YINACTIVE.Fill(oDataSet)
Catch ex As Exception
Me.Log.Write(3, ex.ToString)
End Try

The following error happens on the 'Fill':
System.Data.OracleClient.OracleException: ORA-00933: SQL command not properly ended

If I put a semicolon at the end of the first select, I get this:
System.Data.OracleClient.OracleException: ORA-00911: invalid character

If I separate them into two DataAdapters with two separate 'Fill's into the same DataSet, it tells me I tried to create duplicate data.  I think it is trying to fill the first table twice.

I'm programming in VB.NET with an Oracle connection.  I cannot use stored procedures.

Thanks in advance for any guidance you can give me.

Can you try

daLUT_PERSON_YINACTIVE.SelectCommand.CommandText = "select * from UT_PERSON_YINACTIVE"

daLUT_PERSON_XSELFHID.SelectCommand.CommandText = "select * from LUT_PERSON_XSELFHID"

Hope it helps

As far as I am aware, multiple resultsets are only supported in SQL Server, not Oracle, which is why the Command Not Properly Ended errors are being generated.

If you separate the DataAdapters, it is best to use the Fill command with the Tables in the Dataset specified, so:

Try
     daLUT_PERSON_YINACTIVE.Fill(oDataset.tables("LUT_PERSON_YINACTIVE"))
     daLUT_PERSON_XSELFHID.Fill(oDataset.tables("LUT_PERSON_XSELFHID"))
catch ex as exception
End try

Maybe the vbCrLF is the problem, you do however need the semicolon

r u guys facing below problem?
Dear,
I'm using Microsoft Visual Studio .Net Pro 2003.

I'm using VB.net do develop an simple database application.

The database that I'm using currently is Oracle 8i.

The application having 2 Buttons, hereby call Button A and Button B.

The application start and when I press Button A, it loads the data from the oracle database using "Microsoft .NET Framework Data Provider for Oracle"

but it shows lacking and I want to stress more about it is I only having 10 records in my database!!!

when the data is loaded. I press the Button A again and everything seems goes fine, the data loading speed turns fine.

same thing applies for the button B.

So I'm wondering, last time when I'm using VB6.0, there is no such problem(lacking problem), but why it is lacking for VB.NET and it is always the first time I load the data?

I had try the same thing again on VB6.0 on the same machine same connection to DB, and it works fine.

my Boss is unhappy with this situition and I'm here looking for reply URGENTLY.

thanks for the help and sorry about my poor english.
