[microsoft][odbc Driver Manager] Invalid Cursor State
Invalid Cursor State up vote 0 down vote favorite I am a beginner in writing programs, I have created a search record function for my assignment. public void searchRecord(){ for(int ct = 0; ct< 1; ct++){ System.out.println("Please insert student ID"); System.out.print("Student ID: ");//prompt for student ID to search String data = k.nextLine().trim(); String sql = "SELECT * FROM Students WHERE StudentID = '"+data+"'"; try{ invalid cursor state sql rs = st.executeQuery(sql); if(rs.next()){ displayRecord(); rs.next(); showMenu(); } else{ System.out.print("No record found. "); ct--; } }catch (Exception ex){ System.out.println("Problem searching."); } } However, after I try to get data from the result, it shows Invalid Cursor State. If I want to retrieve data, I'll have to execute the Display next record method which is: try{ if(rs.next()){ displayRecord(); } else{ rs.previous(); System.out.println("No more records!"); } }catch (Exception ex){ System.out.println("There is problem showing next data."); } I tried adding "rs.next" at the search record method after "displayRecord" but it wouldn't solve the problem. Is there anyway to solve this? By the way my display record method: public void displayRecord(){//get and display data from current row of record try{ String ID = rs.getString(1); String fname = rs.getString(2); String lname = rs.getString(3); String conNo = rs.getString(4); String mail = rs.getString(5); String plate = rs.getString(6); Date date = rs.getDate(7); System.out.print("Student ID: "+ID+"\nName: "+fname+" "+lname+"\nCar Number: "+plate+"\nContact Number: 0"+conNo+"\nE-Mail Address: "+mail+"\nDate Registered: "+date); }catch (Exception ex){ System.out.println(ex); } } Any helps or advices are appreciated. java jdbc share|improve this question edited Sep 1 '13 at 13:06 Haedrian 3,34912049 asked Sep 1 '13 at 12:59 Ryan
