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:

Hope this helps!

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.

begin
if (new.col3 is distinct from old.col3)
then new.col5 = current_timestamp;
end#
set term ;#
If col3 is non-nullable you can simply use "new.col3 <> old.col3" in the
test.
Mind you, an explicit update that re-enters the existing value in col3
won't cause col5 to be updated!

o when it's strictly about German, AI collations seem
useless, except for catching certain foreign words and names likes
Gérard/Gerard, or misspellings of Kekulé.
Cheers,
Paul Vinkenoog
ae sind gleich
ö und oe sind gleich
ü und ue sind gleich
ß und ss sind gleich
If you do want to treat them as different letters, you need a German
collation that does just that. However, this collation will not work
correctly with words in some other languages containing ä, ö and ü.

(levels 0-N, each one being the most recent file of that level before

You mean the FishBowl docs? Or the Firebird docs? BTW, this nbackup scheme you
used: did it come with Fishbowl or did you set it up yourself?
Paul Vinkenoog
would be to
always use gbak?
If in any doubt, use gbak. But as you can tell from Sean's post, there are
situations where a straight file copy/move is just as safe. Just make sure you
know what you are doing.

to propose changes to a manual, the preferred way is to

Yes - but where is this global lock table? It doesn't tell me if it's a file
somewhere or in the memory of the first server loaded?
Iirc, it's a lock file in ProgramData\Firebird.

absolutely no other option.
In the situation you described, the logical thing to do would have been ALTER
DATABASE END BACKUP (or nbackup -N) on the original machine (once you found out
the right credentials, which I believe you did).

? After
all, *someone* should know the SYSDBA password, shouldn't they? And how
about the scripts that executed nbackup until they went broken last May?
Do you have read access to them? What authentication method did they
use? And if you can't access those scripts, who can?
Kind regards,

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.

Firebird 2.5.2 - this is not the case. I get an exception
unsuccessful metadata update SYSDBA is not grantor of Role on MANAGER to
0S0ASDFASDF.
You have to use GRANTED BY here:
revoke manager from 0S0ASDFASDF granted by rdb$admin

with a searched delete statement on RDB$USER_PRIVILEGES. Which is a hack of
course, like any direct manipulation of metadata.
It would be better if this were possible in SQL, e.g. by implementing CASCADE
for REVOKE statements (like PostgreSQL has done).

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.

Hi Ed,
merge

Nice trick! That seems to work.
Just realized you can make it even easier:

Frankly, I never noticed that the optional [AS] for table aliases was missing
from the IB6 docs. Now that I know, I'll mention it in the next revision of the
LangRef Update.
