how to find a certain sentence in the database.

[phpnewbie non]

I use php with mysql and it works great. It seems that a particular sentence on the mainpage of the webpage shows text that comes from the database.

( i wanted to remove that from the php/html pages but that piece of text is not found in those files).

So now im wondering how to find out where that text is located in the database so i can remove it. In use phpmyadmin or can use the dos command.

Please advise and thanks for helping
