[Mediawiki-l] backup SQL database

[Frames Project]

Hello,

Before upgrading from mediawiki 1.3.9 to the lastest version, I need to 
backup the SQL  database.

I did it with phpmyadmin : I got an SQL text  file  of 30M.
I tried to read it back ... too big says some php script, without saying 
how to cure this problem.

I suppose some of you have already  have this problem.
(I tried to read MySql and PhpMyadmin docs ... I had quickly been lost)

Thanks
François Colonna
