Q was incomplete. When i do a insert is there a way to know row already exists!!
what is the definition of "row already exists"? If you are concerned about a particular column, make that into a PK. If you are concerned about all the columns, make all the columns into a composite PK. Your program will croak accordingly. Else, just first do a SELECT before doing an INSERT. Use CONFLICT clause to handle conflicts. -- Puneet Kishor http://punkish.eidesis.org/ Nelson Inst. for Env.
