Hi all,

I am trying to execute the bellow code,

private boolean isUserNameExist(){
Users users = getInstance();
String qry = "from Users where userName=:userName AND tenantId =:tenantId";
Query query = entityManager.createQuery(qry);
query.setParameter("userName",users.getUserName()).
setParameter("tenantId", users.getTenantId());
List lst =query.getResultList();

return lst.size() > 0 ? true : false;
}


but i am getting an entirely different exception like bellow.The exception is throwing at "List lst =query.getResultList(); " .

11:22:54,328 ERROR [JDBCExceptionReporter] ERROR: duplicate key violates unique constraint "ad_users_u2"
11:22:54,328 ERROR [AbstractFlushingEventListener] Could not synchronize database state with session

at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:71)
at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43)


Can anybody can help me to fix it.
