Support for ORDER BY Support for ORDER BY The EJB 2.0 Specification supports three SQL clauses in EJB-QL: SELECT, FROM, and WHERE. The <strong>Borland</strong> CMP engine also supports the SQL clause ORDER BY in the same EJB-QL statement, provided it is placed after the WHERE clause. This is done in the standard ejbjar.xml deployment descriptor in the entity. For example, the following EJB- QL statement selects distinct objects from a Customer Bean and orders them by the LNAME field: findCustomerByNumber SELECT Distinct Object(c) from CustomerBean c WHERE c.no > 1000 ORDER BY c.LNAME You can specify either ASC (ascending) or (DESC) descending in your EJB-QL as well. If you do not specify either, the results will be ordered ascending by default. For example, consider the following table: The query: Support for GROUP BY NAME DEPARTMENT SALARY HIRE DATE Timmy Twitfuller Mail Room 1000 1/1/01 Sam Mackey The Closet with the Light Out 800 1/2/02 Ralph Ossum Coffee Room 900 1/4/01 SELECT OBJECT(e) FROM EMPLOYEE e ORDER BY e.HIRE_DATE will produce the following result: NAME DEPARTMENT SALARY HIRE DATE Timmy Twitfuller Mail Room 1000 1/1/01 Ralph Ossum Coffee Room 900 1/4/01 Sam Mackey The Closet with the Light Out 800 1/2/02 The GROUP BY clause is used to group rows in the result table prior to the SELECT operation being performed. Consider the following table: NAME DEPARTMENT SALARY HIRE DATE Mike Miller Mail Room 1200 11/18/99 Timmy Twitfuller Mail Room 1000 1/1/01 Buddy Coffee Room 1000 4/13/97 Sam Mackey The Closet with the Light Out 800 1/2/02 Todd Whitmore The Closet with the Light Out 900 4/12/01 Ralph Ossum Coffee Room 900 1/4/01 156 BES Developer’s Guide
