    *                      SQL does not properly alias all         *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When WebSphere Application Server's implementation of
    VersionStrategy is used on an entity, and a 'find' is executed
    to find the entity, Application Server generates the wrong SQL
    statement where one of the parameters in the SQL is not
    properly aliased.  For example, if there is an entity name
    MY_ENTITY which has persistable fields ID, LAST_UPDATE, and
    COMMENTS, a proper SQL statement to find this entity might
    look something like this:
    
    SELECT t0.LAST_UPDATE, t0.COMMENTS FROM MY_ENTITY t0, WHERE
    t0.ID = ?
    
    Whoever, an SQL is generated like this:
    
    SELECT LAST_UPDATE, t0.COMMENTS FROM MY_ENTITY t0, WHERE t0.ID
    = ?
    
    As can be seen, the 'LAST_UPDATE' parameter is not properly
    aliased with 't0'.
    

Problem conclusion

  • With this fix, code has been added to ensure parameters are
    properly aliased when VersionStrategy is used.
    
    The fix for this APAR is currently targeted for
    inclusion in Service Level (Fix Pack) 7.0.0.15 of WebSphere
    Application Server version 7.0.0.
