insert query with varchar as data type for primary key

Question

The program is not accepting the query given below-

 public class loginDaos {

       public void create(loginBean bean) {
           ConnectionPool c = Connecti         


        

Answer 1

When you are using a PreparedStatement, then you should use the executeQuery(), executeUpdate() or execute() method that does not take a String parameter.

So to fix the problem use:

// ....
pstmt.setString(3, bean.getPassword());
pstmt.setString(4, bean.getPosition());
pstmt.executeUpdate();

The MySQL driver implementation has a bug, because the JDBC specification states that the methods accepting a string should throw an SQLException when called on a PreparedStatement or CallableStatement implementation. In this case it only throws the exception because it tries to execute the parametrized query directly.
