This section describes how MySQL relates to the ANSI SQL standards.
MySQL has many extensions to the ANSI SQL standards, and here you
will find out what they are, and how to use them. You will also find
information about functionality missing from MySQL, and how to work
around some differences.
Our goal is to not, without a very good reason, restrict MySQL usability
for any usage. Even if we don't have the resources to do development
for every possible use, we are always willing to help and offer
suggestions to people that is trying to use MySQL in new territories.
One of our main goals with the product is to continue to work against
getting to be ANSI 99 compliant, but without sacrificing speed or
reliability. We are not afraid to add extensions to SQL or support for
non-SQL features if this greatly increase the usability of MySQL for a
big part of our users. (The new @code{HANDLER} interface in MySQL 4.0
is an example of this strategy. @xref{HANDLER}.)
We will continue to support transactional and not transactional
databases to satisfy both heavy web/logging usage and mission critical
24/7 usage.
MySQL was from the start designed to work with medium large databases
(10-100 million rows / about 100 MB per table) on small computer
systems. We will continue to extend MySQL to both work even better
with terrabyte size data but we are also doing work to make it possible
to compile a reduced MySQL version that is more suitable for hand held
devices and embedded usage. The compact design of MySQL makes both of
these directions possible without any conflicts in the source tree.
We are currently not targeting real time support or clustered databases
(even if you can already do a lot of things with our replication
services).
We don't believe that one should have native XML support in the
database, but will instead add the XML support our users request from
us on the client side. We think its better to keep the main server
code as 'lean and clean' possible and instead develop libraries to
solve the complexity on the client side. This is part of the above
mentioned strategy of not sacrificing speed or reliability in the
server.
