It is important to call all of the MySQL functions in the right order. It is
very easy to skip one if you are just learning. I'm not going to give you the
exact function calls, because there are several sets. Pick a set (PDO works
with different databases, so it is most portable) and then keep
There is no difference.
It's just a marketing thing.
Enterprise is mainly Support + Enterprise monitor,
the source code is exactly the same, the binaries are just (as they say)
with more optimized compilation,
more often patches are released if you are an Enterprise subscriber.
The only extra
I should have mentioned that there is an example for mysql in the
documentation: http://www.php.net/manual/en/mysql.examples-basic.php. It is
the simplest interface, but it is not object-oriented. Mysqli can be used
either as procedures or as objects.
The differences between mysql, mysqli, and

Ah ha! Thanks Derek. I thought INTO was used strictly for inserting the
selected records into another table.
Much appreciated.

I want to create a US geography database. So far I have categories such as
state nick names (some states have more than one), state mottos (text 25 to
150 characters), state name origins (100-300 characters), state trivial
facts, entry into union.
you don't need enterprise for the development environment, you can develop
in community version and deploy in enterprise version. but make sure release
version should be same for both.

Partitioning is available in the community edition and has been for a

According to everything I've read, using LOCK TABLES...WRITE for updates,
inserts and deletes should improve performance of mysql server, but I think
I've been seeing the opposite effect.
I've been doing quite a bit of testing on a 64bit install of CentOS 5.5
installed as a guest OS on a VMWare
LOCK TABLES...WRITE is very likely to reduce performance if you are
using a transactional storage engine, such as InnoDB/XtraDB or PBXT.
The reason is that only one connection is holding the write lock and
no other concurrent operation may occur on the table.
LOCK TABLES is only really
