Can you drop the stock card table instead? That would require that no
running connection have touched the table and introduce the need to backup
and restore the database periodically because there's a limit to the number
of tables you can create in a Firebird database, but it would avoid garbage
collection and be faster than deleting the contents row by row.

How many records are you talking about? Dozens? Hundreds? Millions?

No, and even if there were, using it would be a bad idea. Although garbage
collection takes time, it slows the database less than leaving lots of
unusable record versions in the database.

An alternative is to run SuperServer with the garbage collection option set
to use a separate thread.

Good luck,
