MySQL 5.0 Release Candidate Available

Key new features of MySQL 5.0 come in three groups:

a) ANSI SQL standard features formerly unknown to MySQL
b) ANSI SQL standard compliance of existing MySQL features
c) New MySQL Storage Engines, Tools and Extensions

The new ANSI SQL features include:

* Views (both read-only and updatable views)
* Stored Procedures and Stored Functions, using the SQL:2003 syntax, which is also used by IBM’s DB2
* Triggers (row-level)
* Server-side cursors (read-only, non-scrolling)

Strict Mode: MySQL 5.0 adds a mode that complies with standard SQL in a number of areas in which earlier versions did not; we now do strict data type checking and issue errors for all invalid dates, numbers and strings as expected

New MySQL Storage Engines, Tools and Extensions are:

* XA Distributed Transactions
* ARCHIVE Storage Engine for storing large amounts of data without indexes in a very small footprint, intended for historical data that may be needed for future audit compliance (Sarbanes Oxley or otherwise)
* FEDERATED Storage Engine for accessing data ín tables of remote databases rather than in local tables (only in MAX version)
