I have a problem with JPQL... I'm trying to make a web app with Vaadin, Shiro, MySQL, JPA... I have made a desktop app a few years ago and use all libs for JPA from that project. I have a problem with mysql-connector-java-5.0.8-bin.jar. When I try to run the project I become a SQL exception com.mysql.jdbc.driver not found. Few people had the same problem and solved it with replacing mysql connector 5.0.8 with 5.1.17 or higher. I made this and I have now a new problem with queries.

This query works fine :

TypedQuery<Products> q = em.createQuery("SELECT e FROM Products e",Products.class);
List<Products> products = q.getResultList();

This query doesn't work fine :

TypedQuery<Products> q = em.createQuery("SELECT e FROM Products e WHERE e.name LIKE 'something'",Products.class);
Products products = q.getSingleResult();

I become this exception:

Thank you...

EDIT 1 I have tested another query and it wokrs fine too... 

TypedQuery<Products> query1 = em.createQuery("SELECT e FROM Products e WHERE e.name LIKE 'something' OR e.name LIKE 'somethingElse' ",Products.class);
List<Products> list = query1.getResultList();

Where statement is not the problem. The problem is getSingleResult, but I don't know how to solve it... Thank you...

  • you mean when you don't put a space in between LIKE and the expression? Surprising? – Neil Stockton Jun 27 '14 at 06:04
  • No, just when I use query.getSingleResult() method... I run the same query with query.getResultList() and it works fine... – xXxJAVAxXx Jun 27 '14 at 06:31
  • you have to have a SPACE between LIKE and the argument. If you really have a space between those in the failing JPQL then I strongly suggest you fix your post to show that – Neil Stockton Jun 27 '14 at 06:45

CAn you try like

TypedQuery<Products> q = em.createQuery("SELECT e FROM Products e WHERE e.name LIKE   :something ",Products.class);
q.setParameter("something ", something );
Products products = q.getSingleResult();

Products products = em.createQuery("SELECT e FROM Products e WHERE e.name = :name1 OR e.name = :name2", Products.class).setParameter("name1", "value1").setParameter("name2", "value2").getSingleResult();

OR

Products products = em.createQuery("SELECT e FROM Products e WHERE (e.name LIKE :name1) OR (e.name LIKE :name2)", Products.class).setParameter("name1", "value1").setParameter("name2", "value2").getSingleResult();

You must remember about syntax of JPQL. In WHERE clause if you pass parameters you can add two operators: = and :, where = sign is assign sign and : is information that next there will be name of passing parameter (:parameter_name)
