Hi,

In one of my JPA 2.0 entities I have this query:

@NamedNativeQueries({@NamedNativeQuery(name = "CustomItem.count", query = "SELECT IFNULL( (SELECT MAX(customItemId) FROM CUSTOMITEM) ,1)")})

and the Java code that uses it is:

int noOfCustomItems = (Integer)entityManager.createNativeQuery("CustomItem.count").getSingleResult();

The sql code of the NamedNativeQuery :

SELECT IFNULL( (SELECT MAX(customItemId) FROM CUSTOMITEM) ,1)

executes just fine from the mysql command line prompt, but exactly the same code executed by JPA 2.0, throws this exception :

Local Exception Stack:

Your are calling the wrong method,

createNativeQuery(String sql)

this creates a "new" query using the "sql"

You want,

createNamedQuery(String name)

You are executing "CustomItem.count" as the MySQL error is telling you.
