Letters and underscore detected in a LIKE string

  Explanation:  The converter converts MATCHING  string  constants
  to  use  the  LIKE wildcard characters.  There is no way to have
  both letters and an underscore in a LIKE target string that will
  still  have the same semantics as the original, because SQL only
  permits either IGNORE CASE or an ESCAPE character, but not both.
  The  converter  will generate IGNORE CASE andthe underscore will
  act as a wild card, matching ANY single character (as  '%'  does
  in MATCHING.

  User Action:  Change the target pattern.
