Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-597
    Summary: Criteria API - NOT IN not working on MySQL
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.1.1

   Assignee: 
   Reporter: Michael Gloegl

    Created: Fri, 2 Jan 2004 5:42 PM
    Updated: Fri, 2 Jan 2004 5:43 PM
Environment: Hibernate 2.1.1, MySQL

Description:
On MySQL the SQL generated by a Criteria query like

Object o =
	session
		.createCriteria(Event.class)
		.add(Expression.not(Expression.in("id", id_values)))
		.uniqueResult();

does not work. Hibernate generates a SQL like 

SELECT * FROM Event WHERE NOT id IN ( 1, 2, 3, 4, 5  ) 

This should work, but MySQL does not get the operator precedences right. This works by using explicit brackets, or by placing the NOT after the column name.

I attatch some possible patches to fix this.
