You cannot write DDL in a stored procedure.

If you really really want to do this, you can do it via
EXECUTE STATEMENT in Firebird 1.5 -- but
deactivating triggers inside a stored procedure sounds
like a very bad idea and a hack to me.

This idea isn't multi-user safe anyway.

What are these actions?
