Correct query causes error with Zeos

This is a valid query in Firebird/Flame Robin (and some other databases/managers) but Zeos reports an error:

select id, '' as ERROR_WITH_ZEOS from some_table

SQL Error: Incorrect values within SQLDA structure; empty pointer to data; at SQLVAR index 1.

(Firebird 3, Zeos 7.3 latest, Delphi 2009)

I created a ticket to track this: https://sourceforge.net/p/zeoslib/tickets/426/

Best regards,

As far as I can see, the problem has already been solved in r6507.

Great job.
