I'm trying to update my data source using the Update method in
OleDbDataAdapte r with automatic command generation and I got error "Dynamic
SQL generation for the UpdateCommand is not supported against a
SelectCommand that does not return any key column information.". Does any
one know what I am missing? My codes look like this:
' Where the connection string is "Provider=Micro soft.Jet.OLEDB. 4.0;Data
Source="C:\myDa taFile.mdb;Mode =ReadWrite|Shar e Deny None"
mDBAdapter = new OleDbDataAdapte r ()
mDBAdapter.Sele ctCommand = New OleDbCommand ("Select Id, Pacakge from
_mPackage Where Obsolete=0 Order By Package", mDBConn)
mDBCmdBuilder = new OleDbCommandBui lder (mDBAdapter)
mDBDataSet = new DataSet()
mDBConn.Open
mDBAdapter.Fill (mDBDataSet, "_mPackage" )
Try
Din nRow as Integer = mDBAdapter.Upda te (mDBDataSet, "_mPackage" )
Catch oEx as System.Exceptio n

Hi,
I need to update tables in access 97. The table names have spaces (not my
choice). My update fails even though I use the OleDbCommandBuilder.
Here is a code I am using

I create 2 data OleDbDataAdapters, one with the wizard, and one in

fill a data table.
However, when I try to use the same SQL insert statement in the two

adapter created in code gives me an error "Object reference not set to

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
