PARALLEL hint ignored in PL/SQL block?
Date: Thu, 31 Jul 2008 10:28:37 +0300
When following DML is executed standalone
Insert into tableA select /*+ parallel(B) parallel(C) */ * from tableB_at_link B, tableC_at_link C where <some conditions>;
tableB and tableC are accessed in parallel and everything is fine.
However, if this is executed within PL/SQL block (or within stored procedure), tableB and tableC are not accessed in parallel. What may be the reason for this behavior? My goal is to improve performance of datamart batch load jobs.
