<str> inserted before error symbol

  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
  inserted the specified token before the token that generated the
  error, and generated this message to help you understand any
  additional messages that follow.
