MySQLIntegrityConstraintViolationException: Duplicate entry

Zulfi KhanFeb 18 2017 — edited Feb 26 2017

Hi,

I have created a table with id as a primary key.

When I am entering same id again & I am getting following errors:

MySQLIntegrityConstraintViolationException: Duplicate entry

I am catching SQLException:

catch(SQLException se){

      //Handle errors for JDBC

      JOptionPane.showMessageDialog(null, "Testing");

      se.printStackTrace();

   }

The control enters into catch block &

Its printing "Testing". So exception is caught. So why i am getting this error. Some body please guide me how to handle this error.

Zulfi.
