The MySQL developers have released milestone 2 of MySQL 5.5, on the path to a general release in mid-2010. The new milestone release incorporates semi-synchronous replication in MySQL 5.5 based on patches to InnoDB developed by Google.

MySQL now has a new "database" named INFORMATION_SCHEMA. It is a virtual database only; there will never be a need to create a file by that name, and the MySQL server itself creates and populates the tables therein.

Many of us do not realize that MySQL's Timestamp is not the timestamp which PHP date() understands. In fact if you try to use MySQL timestamp directly in php date() function then you will get totally wrong dates. There is a simple way to use MySQL timestamp data in php.

MySQL user who wants to know "what's new" in version 5. The short answer is "stored procedures, triggers, views, and information schema". The long answer is the MySQL 5.0 New Features series, and this book is the third in that series.

To delete duplicates from a MySQL database table I normally copy the duplicate data first to a temporary table and then use the copied id's to delete from the original table.

MySQL 5.0 introduced Stored Procedures which allow us to automate or program our way out of many tasks on directly on the server rather than having to write external scripts to do complex manipulation of data.

Whenever I want to show actual code, such as something that comes directly from the screen of my mysql client program, I switch to a Courier font, which looks different from the regular text font.

Here is a simple command to auto repair, check and optimize all the tables in all databases running on a MySQL server:

To delete duplicates from a MySQL database table I normally copy the duplicate data first to a temporary table and then use the copied id's to delete from the original table.

mysqlcheck uses the SQL statements CHECK TABLE, REPAIR TABLE, ANALYZE TABLE, and OPTIMIZE TABLE in a convenient way for the user.

This will kill the mysqld process. However the best way to stop (because it stops properly) is obviously

The process of sending and receiving asynchronous messages by different processes in SQL Server 2005 is enabled by the Service Broker.

This will kill the mysqld process. However the best way to stop (because it stops properly) is obviously:

The following examples make use of PostgreSQL's implementation of PL/Perl, but the examples should be relevant and similar to other procedural language extensions in most databases that support such additions.
