Error description

  • A query may return more rows than expected when the following
    conditions are satisfied:
    - the query has multiple inner joins between column-organized
    tables, using equality join predicates
    - the same columns from the same tables are repeatedly used in
    many of these equality join predicates
    - at least one such equality predicate involves a join between
    such a column and an expression
    The issue is access plan dependent.
