Im sorry I made a major mistake...the module Im using is DBD::mysqlPP, the reason Im using the module is that my client's hosting service refuses to install the DBD::mysql module...

Anyway I wanted to say thanks for your answers and sorry for not been clear since the begining...

I tried to look for a new version of this module but it seems that I already have the newest one..I hope someone can help me sort this out...

Thank
