OK, so shoot me but I'm confused by the TDS error handling/catching. I
can see all these directives:

#define TDS_SUCCESS, TDS_FAIL, TDS_CMD_FAIL etc. but where do I use
them? Some even have the same number.

For example, if I send a query to the server with tds_query_submit and
that query fails (incorrect table name say) what would the return code
be? Or is this caught from within tds_process_results or whatever? What
about if the SQL command succeeds but returns no rows what then? I
realise that the err_handler of the TDSCONTEXT structure can print error
messages but what if I actually want to handle the error by using some
code?

Can someone clear this up for me please!

Cheers

James Vanns
