Changes since version 5.0.22:
- Security fix: If a user has access to MyISAM table t, that user can
create a MERGE table m that accesses t. However, if the user's
privileges on t are subsequently revoked, the user can continue to
access t by doing so through m. If this behavior is undesirable, you
can start the server with the new --skip-merge option to disable the
MERGE storage engine. (Bug#15195)
- In the INFORMATION_SCHEMA.ROUTINES table the ROUTINE_DEFINITION
column now is defined as NULL rather than NOT NULL. Also, NULL rather
than the empty string is returned as the column value if the user does
not have sufficient privileges to see the routine
definition. (Bug#20230)
- Several other bug fixes
MySQL is a SQL (Structured Query Language) database server. SQL is the
most popular database language in the world. MySQL is a client-server
implementation that consists of a server daemon `mysqld' and many
different client programs/libraries.
The main goals of MySQL are speed and robustness.
The base upon which MySQL is built is a set of routines that have been
used in a highly demanding production environment for many years. While
MySQL is still in development it already offers a rich and highly useful
function set.
The official way to pronounce 'MySQL' is 'My Ess Que Ell' (Not MY-SEQUEL).
This package contains the MySQL server programs and libraries.
