when you say it doesn't work - do you mean that it's unpredictable?
Please note that SELECT FIRST syntax is totally meaningless (at best) and
absolutely unpredictable (at worst) without an ORDER BY clause.
FIRST what? there is not such thing as natural order in Firebird.
So,... please try again with an order by clause and report back.
