MySQL 5.0 achieved General Availability (GA) status with MySQL 5.0.15, which was released for
production use on 19 October 2005. Note that active development for MySQL 5.0 has ended.
B.1.2: What is the state of development (non-GA) versions?
MySQL follows a milestone release model that introduces pre-production-quality features and stabilizes
them to release quality (see http://dev.mysql.com/doc/mysql-development-cycle/en/index.html). This
process then repeats, so releases cycle between pre-production and release quality status. Please
check the change logs to identify the status of a given release.
MySQL 5.4 was a development series. Work on this series has ceased.
MySQL 5.7 is being actively developed using the milestone release methodology described above.
MySQL 6.0 was a development series. Work on this series has ceased.
B.1.3: Can MySQL 5.0 do subqueries?
Yes. See Section 13.2.9, "Subquery
B.1.4: Can MySQL 5.0 perform multiple-table inserts, updates, and deletes?
Yes. For the syntax required to perform multiple-table updates, see
for that required to perform multiple-table deletes, see
A multiple-table insert can be accomplished using a trigger whose
multiple statements within a
INSERT
B.1.5: Does MySQL 5.0 have a Query Cache? Does it work on Server, Instance or Database?
Yes. The query cache operates on the server level, caching complete result sets matched with the
original query string. If an exactly identical query is made (which often happens, particularly in web
applications), no parsing or execution is necessary; the result is sent directly from the cache. Various
tuning options are available. See
B.1.6: Does MySQL 5.0 have Sequences?
No. However, MySQL has an
inserts in a multi-master replication setup. With the
auto_increment_offset
increment values that don't conflict with other servers. The
value should be greater than the number of servers, and each server should have a unique offset.
B.1.7: Does MySQL 5.0 have a
No. This is on the MySQL roadmap as a "rolling feature". This means that it is not a flagship feature,
but will be implemented, development time permitting. Specific customer demand may change this
scheduling.
However, MySQL does parse time strings with a fractional component. See

TIME
B.1.8: Does MySQL 5.0 work with multi-core processors?
Yes. MySQL is fully multi-threaded, and will make use of multiple CPUs, provided that the operating
system supports them.
B.1.9: Why do I see multiple processes for mysqld?
When using LinuxThreads, you should see a minimum of three
in fact threads. There is one thread for the LinuxThreads manager, one thread to handle connections,
and one thread to handle alarms and signals.
