Error symbol replaced by <str>

  Explanation:  When parsing an SQL statement, the parser
  encountered an error.  The message for that error appeared prior
  to this message.  In an attempt to recover from that error, SQL
  replaced the token it found with the specified token, and
  generated this message to help you understand any additional
  messages that follow.
