Detecting "raiserror" from stored procedure (3 replies)
microsoft.public.dotnet.framework.odbcnet
I have an application that runs a stored procedure in Sybase. I originally used the OleDb classes, but because of flakiness in the Sybase OLE DB driver, I'm looking at switching to ODBC.

With OleDb, this would throw an OleDbException with the text passed to raiserror in the Message property...
