Hi,

Maybe, and maybe not. Have you look for at IT or Database forums in your
country?

> have know about it ?

Unfurtunatly I don't.


Well, if you really can't get help from someone at your country, then try to
be more precise on describing your problems. Tell your actions, detailed
error messages, your SQL code or DDL when asked. Try to be more
communicative!!!

Good luck,
