    Description

      Oracle specific OPTIMIZER hints that have the following block structure should be ignored when SQL_MODE=ORACLE is used

      Hints are given using "/*+ <Hint Identifier> */" block.

      Example: "INSERT /*+ APPEND */ INTO ... VALUES ..."

      Here "/*+ APPEND */" is the hint to the Oracle's optimizer.
