missing parameters in Report before SQL Events

Some issues found with phpr 5.2

1. only $strWhereClause is available and $strSQL, $strOrderBy are missing.
   
2. $strWhereClause is not working as it append to the end. When
   
   your query string consist of ORDER BY or Group, it append the
   $strWhereClasue after it.
   => .... WHERE field_a = "b" Order by field_a AND field_d = "e"
   (In phpr 5.1, the whole before SQL event are totally missing,
   
   which cause unwanted data to be shown to user in the report)
   Thanks
