Hi,
is there, performance wise, any difference whether I create one index
for multiple fields or each field with its own index? I'm running 4.0.16.
thx,

If you upgrade to mysql 5.0.x there are also the
The INFORMATION_SCHEMA tables that return meta information
about tables.
AFAIK they may not be available in pre 5.0 versions.

In theory, theory and practice are the same;
in practice they are not.

What you are looking for is the INFORMATION_SCHEMA views, but they are not
available before 5.0. Until then you have to parse the show create table
or DESCRIBE tablename may be easier to parse
mysql describe organizations;

As I said -- take a look at the SHOW commands in the documentation :-)

Is there a recommended GUI that will administer multiple MySQL 4.x

We use that to monitor dozens of servers, over 1000 individual items
(disk space, web server up/down, etc). We also do some heavy monitoring
of oracle databases and some moderate mysql monitoring. It can be
easily adapted to do what you want. And it's free!
