'  How to Generate your stored procedures:
' 
'  SQL      = SQL_DAAB_StoredProcs.vbgen
'  
'  This object is 'abstract' which means you need to inherit from it to be able
'  to instantiate it.  This is very easily done. You can override properties and
'  methods in your derived class, this allows you to regenerate this class at any
'  time and not worry about overwriting custom code. 
'
'  NEVER EDIT THIS FILE.
