Error description

  • Queries containing OUTER JOIN operations and an OLAP function
    nested within one of the input operands may perform poorly under
    certain conditions.
    
    - The sub-select feeding the OLAP function shall contain either
    literal values in the select list or equality predicates between
    a column and a literal.
    - The ON clause of the OUTER JOIN shall reference the derived
    column produced by the literal value or the column in the
    equality predicate.
    
    UPDATE/DELETE/INSERT statements involving triggers or causing
    the update to a materialized query table may also be susceptible
    to this issue.
