Error description

  • In DPF environment, when a SQL statement meets the following
    conditions, compiling it can take a long time or run out of
    memory (SQL0101N)
    
    1. Two tables are joined together using a lot of equality
       predicates.
    2. One (or both) of the tables is a derived table that is
       derived from a query that contains a group by clause, and
       such group by clause have a lot of group by columns.
    3. Some (or all) of the group by columns participate in the
    equality join predicates.
    
    For example
    
    select ...
    from (select ... from T group by <a lot of columns>) as T1, T2
    where <a lot of equality join predicates>
