inserting values in database....

[Mahajan Bhupendra]

hi ,
i got stucked with sql-servlet combination...
i have worked comfortably with select statements..
i tried one insert statement and i got the problem
rs=st.executeQuery("insert into Result (Name,Roll_no) values('"+req.getParameter("name")+"','"+req.getParameter("roll_no")+"');");

this is the actual statement and it inserts values in database
also but throws an exception..
java.sql.SQLException: No ResultSet was produced
what do i do so that i won't get the exception?
also if i just want to check that if some value is there in
database or not e.g. user name and poassword, which sql
statement should i use?
Thanx for ur helping hand...

The insert statement does not create a result set, unlike a select statement. I think you may want to use the executeUpdate() methoed rather than the executeQuery() method. executeUpdate() will return an int representing the number of rows affected.
