I have an iboquery, and I am trying to do something like:

select rdb$db_key from products;

If I put this sql into the query and execute it, if I try

fieldbyname('rdb$db_key').AsString I get an exception saying the
fieldname does nto exist

Can I reference the rdb$db_key field in the IBOquery components? If
so, could anybody give me an example of how I can do this?

Thanks,
