type casting and condition checking while inserting into the DB.

Hi All,

I just have a query that if i use an integer

attribute to be stored inside the database,i get get a

comma seperating the thousand value.so instead i used it

as a string attribute and type casted it and stored

inside the DB.Now my problem is, if i want to check the

condition that the value i m passing inside the

inputfield should not be a string how could i do it?
