MySQL, stored procedures and callable statements

The stable 3.x versions of MySQL don’t support stored procedures. Consequently the associated JDBC driver can’t support callable statements. The alpha 4.x versions don’t support stored procedures either, but support for stored procedures (and therefore callable statements) is announced for the development 5.x versions at this time of writing.

This info can be important when you consider e.g. to replace an Oracle DB of an application with a MySQL DB.
