Zafar, You need to test for the null after you have retrived the parameter from the query, via jdbc ResultSet.wasNull()
Code might look like CallableStatement cs; // setup the callable statement stuff prior to here ResultSet rs = cs.executeQuery(); while (rs.next()) { String param = rs.getString(pos); if (rs.wasNull() == true) { // set preferred param value param = "0"; // or "" } } Hope this helps Bill -----Original Message----- From: zafar Ahsan [mailto:[EMAIL PROTECTED] Sent: Monday, 10 March 2003 6:16 PM To: [EMAIL PROTECTED] Subject: Pls help me !!
