Hello,
I have 2 questions regarding InnoDB tables:
1. In the MySQL manual, it states that
"MySQL begins each client connection with autocommit mode enabled by
default. When autocommit is enabled, MySQL does a commit after each SQL
statement if that statement did not return an error."
Does using BEGIN override this behavior? In other words, with

Below is what I got by using MySQL's --log startup option. The original
Java(with JDBC driver) program that creates the queries at runtime was coded
by other people, and unfortunately, they are not available to answer any
question.
My question is: Do we need so many "SET autocommit=1" at all? Bu default,
MySQL always starts a new connection with autocommit
enabled.(?dev.mysql.com/doc/mysql/en/InnoDB_and_.., do we need to do "SET...

Hi all,
I've got MySQL 4.1.3 installed on RH 7.3... everything's fine so far
except for getting the init_connect string to work.
I followed the instructions on
http://dev.mysql.com/doc/mysql/en/Server_system_variables.html
and added the below line to my '/etc/my.cnf' file under :

Hi,
Please see the history below...
Does AUTOCOMMIT as used here functionally replace VACUUM ANALYZE?
If I turn on AUTOCOMMIT is every transaction commited as it is
executed? If this is the case the query will take about twice as
long... I have actually tested this scenario.

Hola.
He instalado postgres 7.4, y vi que ya no es posible hacer un "alter
database ... set autocommit = off"
Leyendo la documentacion de 7.4, encontre lo siguiente:
Note: The autocommit-on mode is PostgreSQL's traditional behavior, but
autocommit-off is closer to the SQL spec. If you prefer autocommit-off,
you may wish to set it in your .psqlrc file.

Hi,
We've been using the perl DBD::DB2 driver on Perl version 5.8.0
(aix_thread_multi) for a project we're working on without any problems
until now.
We've been using DBD::DB2 version 0.78 on DB2 Version 8.1 (the db2 cli
reports 8.1.0) and we've recently updated DB2 using FixPack 7. The
project we're working on uses the DB2 driver for some webpages and a
couple of daemon scripts. On the DB2 version without the FixPack the

I'm looking to get a little more performance out of my database, and saw in
the docs a section about disabling autocommit by using the BEGIN and COMMIT
keywords.
My problem is this: I enforce unique rows for all data, and occasionally
there is an error where I try to insert a duplicate entry. I expect to see
these duplicate entries and depend on the DB to enforce the row uniqueness.
When I just run the insert statements without the...

With the advent of postgres v8, would it be possible to change the
default behaviour of psql from AUTOCOMMIT=ON to AUTOCOMMIT=OFF ?
Although this might break backward compatibility, it might be acceptable
on the basis that v8 is such a major release.
Also adding a new command line parameter to control the AUTOCOMMIT
setting for those users that will experience broken scripts executed
(especially using the -c command) might help ease...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
