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
MessageBox.Show (oEx.Message)
End Try

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

myDataAdapter.SelectCommand = New OleDbCommand("Select * from ", MyConnection)

I create 2 data OleDbDataAdapters, one with the wizard, and one in
code. I know the adapter created in code is OK because I use it to
fill a data table.
However, when I try to use the same SQL insert statement in the two
adapters, the adapter created with the wizard works fine, but the
adapter created in code gives me an error "Object reference not set to
an instance of an object". The code is below. What am I doing wrong?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
