Hi, I dont know what i am doing wrong here, if someone through some
suggestions on this it would be wonderful, give me a little detail as
to why it could happen. I seems to be from a string lib used by mysql
lib.

Thanks

Ankur

You're going to have to boil this down to a simpler example, and provide
