The short answer is probably merge the two databases manually and
rebuild the index. I don't think there's any real answer otherwise.
Given the old version of MySQL you aren't going to be able to do
anything fancy like federating the two

In more recent version you can do a simple...

Hi Philip,
Thank you very much for your help.
Can you please tell me the differemce between COUNT(*) and COUNT(id) ?
Thanks again.
Actually sorry I was a bit misleading there. MySQL is optimized to

First off, what version of MySQL are you running and on what platform?
Now when i use --skip-grant-tables i can see my databases.
Please help me...
When you use MySQL via a shell I would assume you're logging in as root?
You also say you can only see a test database, can you not see

Just make a backup of the database to a file using mysqldump and then

Without getting into the specific problem the general debug path I'd
