    Description

      The following filters for a number are always true

      x > 0 or x <= 0 or x is null
      x < 0 or x >= 0 or x is null
      x < 1 or x > 0 or x is null

      where the 1/0 can be replaced by any number where the first is greater than the second

       

      The following filter for a varchar is always true:

      x LIKE '%' OR x is null

      It would be nice if RexSimplify.simplifyOrTerms handled these cases.
