SQLException: This ResultSet is closed

Question

I am trying to compare values from three Resultset, but there seems to exception wen I try to run it. Could someone help me on where am going wrong. I will app

Answer 1

java.sql.ResultSet rset = pstmt.executeQuery("SELECT DISTINCT payment_mode, transaction_type, credit FROM ac_cash_collection WHERE shift_no = '" + shiftNumber + "'");
java.sql.ResultSet rset2 = pstmt.executeQuery("select debit from ac_cash_book where shift_no='"+shiftNumber+"'");

Your second call releases the resources generated by the first one, that's why the ResultSet is closed.
