    wardk,

    I think it is different when running over freeTDS on linux, because when I tried to do it as two seperate commands, @@IDENTITY was empty. I think it has something to do with the concept of "current session", but I don't really know.

    Nice work in Identity nabber for MSSQL, by the way.

    Thanks,
    Scott

      If the value for @@identity is empty when doing this as two requests it means that the select @@identity is done on a different physical connection from the insert. This usually happens when you don't completely flush all the results after the initial insert.

      I'm thinking of adding an attribute to DBD::Sybase that would inhibit the automatic secondary connections to handle multiple concurrent $sth on a single database handle as that causes quite a lot of confusion for people...

        Since you are using two commands off one prepare, you may need to
        use the:

        while ( $someVar = $sth->fetch ) { do ( something... ) while ( $sth->{syb_more_results} );

        syntax.

        This is explained in the "Programming the Perl DBI" book
        PG: 326 Don't know if it helps - but it's worth a try.
