Did not see the strict. In any case I thought cleanSessionTable was
cleaning out app_security.app_sessions not app_security.app_val_session_vw.

Assuming something else is going you have two options(sense a theme?):

1) Remove the strict and do as I suggested in the previous post.

2) Move the count and IF before the select * into .. and then do what
you want.
