How to create an INSERT IGNORE query in Hibernate?

Question

Hibernate has to make inserts in a table which has an unique field. I want to ignore duplicate entries so that my program keeps running. In MySQL I would simply say INSERT IGNORE , but I can't figure out how to do that in Hibernate. Any suggestions? Thanks!

Answer 1

Have you tried using the @SQLInsert annotation ? This way, you can overwrite the Hibernate statement with your own custom SQL and use INSERT IGNORE :

@SQLInsert(sql="INSERT IGNORE INTO CUSTOMER(id,name) VALUES(?,?)")
class Customer{
   ...
}

Answer 2

if you are using a simple SQL query, use following code.

               Query query = session.createSQLQuery("INSERT IGNORE INTO user (name,username) VALUES (:name,:username)");
               query.setParameter("name", name);
               query.setParameter("username", username);
               int i= query.executeUpdate();
