Closed as program error.
Error description
Data sources such as Oracle have a different character comparisons semantics than UDB. UDB has a blank pad comparison, while Oracle has a non-blank pad comparison. Therefore, comparison operations cannot be pushed down to Oracle. To improve performance (i.e. push down the predicates), compiler is generating another predicate with both sides blank padded. However, the predicate padding only takes place if the tables appear in a certain order in the FROM clause.
