And Helen Borrie's Firebird Book is a great manual which also includes
chapter(s) on SP's, triggers and PSQL. It's not free though! You'll find
it here:

My fault! If forgot the trigger name. It should be:
create trigger MyTrigger before update on Table_Name ...
Instead of MyTrigger, you choose a more meaningful name of course.

If col3 is non-nullable you can simply use "new.col3 <> old.col3" in the

Mind you, an explicit update that re-enters the existing value in col3
won't cause col5 to be updated!

If in any doubt, use gbak. But as you can tell from Sean's post, there are

If you want to propose changes to a manual, the preferred way is to
submit them to the firebird-docs list (to subscribe, mail to
firebird-docs-requ...@lists.sourceforge.net)
People who write or update documentation regularly can get CVS access.

Then you can also do
Var2 = 1 - Var1
The outcome is the same, but perhaps this is more obvious than bitwise XORing
with 1. And it might execute a wee little faster.

In a pure SQL script, I wouldn't know.
But your application could check if the UDF name exists in RDB$FUNCTIONS and if
so, execute DROP EXTERNAL FUNCTION.

equal privileges now without finding out the grantors first, it has to be done
with a searched delete statement on RDB$USER_PRIVILEGES. Which is a hack of

It would be better if this were possible in SQL, e.g. by implementing CASCADE
for REVOKE statements (like PostgreSQL has done).

merge

using temp
on emp.fruits = temp.fruits
when not matched then insert (fruits) values (temp.fruits)
