There are several versions of MySQL web hosting. However, if you are using MySQL web hosting for the first time, it is better to opt for version 4.1 as it is default on most web hosting for MySQL systems. The following are the MySQL versions that are commonly used at this time.

* MySQL 4.0: This version is the old stable release and hardly any MySQL web hosting provider uses them. Though new releases are issued, they only help to fix extremely critical bugs.
* MySQL 4.1: This stable release has been followed by several new releases so as to fix the critical bugs and other security problems.
* MySQL 5.0: This is the current stable release that follows the SQL: 2003 syntax. This MySQL web hosting can even return multiple result sets in a single invocation.
