Hi Dario,
I've been working on this code recently and fixed a couple of bugs that
cause this problem. I hope to package a build this week if you can wait for
that to test...
Historically, the code that does this is about the only code that was lifted
almost verbatim from the old pgAdmin code. It relies on Microsoft ADO & ODBC
to provide information such as pkeys about the resultset which unfortunately
is not reliable. In order to overcome this, I had 2 choices:
1) Try to match all columns in the SQL (which I opted for). This gives the
advantage that multiple rows can be updated or deleted if required (ADO just
throws an error if this would happen).
2) Parse the SQL query and try to figure out what the result set will look
like. This is *horrendously* complex to do and is best left to the
PostgreSQL backend.
HTH, Regards, Dave.
