A stored procedure is by definition a collection of SQL statement
stored and executed in the RDBMS, not an external script, etc.

Just curious, but is this a 8-bit (smalint maybe?) or approximate 8-byte integer?

Since I been working implementing some triggers in my system
recently this suggestion first came into my mind:
create a delete trigger for the user table. Every time a user it deleted,
the trigger fires and could for example moves this information to a history
table, with date of deletion, etc. T
Why do you want to restrict the names to be unique?

The answer is: Because the SQL query with COUNT(*) only returns one row...

An webserver uses mostly CPU resources while a DB uses I/O, or?
Separation between the webserver and the RDBMS also suggest increased
delays with IPC. I think one needs to find a balance somewhere in between,
and I guess the only way to tell is to actually measure the performance of
the system t

Well, usually my queries could look like this:
insert into #report (Line)
select isnull(a.Object, '') + char(9)
+ isnull(c.ClusterId, '
oes not generates a syntax error here, this might
be a source of introducing faults in the system. That's why it is important
to know exactly how the system behaves. No I know this, but is there other
surprises that I would like to know about?

uates to true.
Also it seams like this is not ISO SQL, so it could be a bit tricky
to predict the outcome without actually having some specification of
the behavior.

Is this a documented behavior of MySQL(?):
mysql> create table test (a int);
Query OK, 0 rows affected (0.03 sec)
mysql> insert into test values(0);
Query OK, 1 row affected (0.00 sec)
mysql> insert into test values(0);
Query OK, 1 row affected (0.00 sec)

Did I ask for optimization tips?
Nope. ;)
But I did ask for a release date of version 4.1.

Installed MySQL and about the first thing I tried to create was a stored
procedure - failed.
Found out fairly quickly with a text search in the manual that stored
procedures is not to be introduced until version 4.1.
Checked my own version and found it to be "Ver 11.16 Distrib 3.23.49".
