JSP Strings, Ints converting

Question

I'm sure this sort of thing has been asked but i cant find it in the forums.... I'm trying to read in a string from a form and then convert it to an int so that i can use it in a select statement so i can compare it to a field declared as "Number" in the Access Database.
String sess = request.getParameter("num"); //num comes from form
int eventNum = Integer.parseInt(sess);
//connected ot the database
String query = "SELECT * FROM EVENT WHERE event_id = 'eventNum' ";
ResultSet result = stmt.executeQuery(query);
//event_id is a number in the database
Its saying "Data type mismatch in criteria expression"
Thanking you in advance,
Brian

Answer 1

Since you are building a string as query, you don't need to convert it
String sess = request.getParameter("num"); //num
String query = "SELECT * FROM EVENT WHERE event_id ='eventNum' ";
ResultSet result = stmt.executeQuery(query);This error "Data type mismatch in criteria" comes from event_id = 'num'
event_id is numeric, so it should not contain quotes in the sql statement
this will do it:
String query = "SELECT * FROM EVENT WHERE event_id =" + sess
