Invalid Cursor State Odbc
it only takes a minute: Sign up JDBC - 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 = invalid cursor state sql k.nextLine().trim(); String sql = "SELECT * FROM Students WHERE StudentID = '"+data+"'"; try{ 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

Join freetds invalid cursor state them; it only takes a minute: Sign up Java SQL Exception Invalid Cursor State - no current row up vote 4 down vote favorite 1 I've been having a hard time trying to figure this out. First I have http://stackoverflow.com/questions/18558661/jdbc-invalid-cursor-state an insertProduct(Product p) method that is supposed to check if a product with the specified code exists in the database. If so, this method will display an error message. Otherwise, it should add the product to the database and print it to the console. I'm not sure if I'm doing that correctly. Second, the deleteProduct(Product p) method is supposed to delete the product that was added by the insertProduct method. Now the thing is that I keep getting http://stackoverflow.com/questions/16576331/java-sql-exception-invalid-cursor-state-no-current-row a SQL Exception when I try to add the product and then the deleteProduct method just keeps deleting the products that are in the database one by one each time the program is run until non are left. I'm not sure what's wrong with both of these methods. Console Output: Derby has been started.

The current error is javax.servlet.ServletException: java.sql.SQLException: [Microsoft][ODBC Driver Manager] Invalid cursor state and this is the piece of work thats causing the error String query3 = "SELECT Last(threadID) AS thread2 FROM msthread"; ResultSet invalid cursor state rs = stmt.executeQuery(query3); rs.getString("thread2"); The result of that query is only to return 1 column and 1 row, ran it through MSAccess and it showed exactly what I wanted to see. This is exactly what it looks like: thread2 43 But now I kept getting the Invalid Cursor State error. I have no idea why.

So use: if (rs.next()) { rs.getString("thread2"); } (or a while loop) share|improve this answer answered Jan 15 '14 at 11:29 Mark Rotteveel 36.3k84677 Correct answer.
