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

MySQL's autocommit

by: jy2003 | last post by:

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.

AUTOCOMMIT didn't work...

by: Lynn.Tilby | last post by:

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.

autocommit off

by: Carmen Gloria Sepulveda Dedes | last post by:

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.

disabling autocommit

by: Matt Van Mater | last post by:

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...

psql + autocommit

by: John Sidney-Woollett | last post by:

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...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

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,...
