(B)0containing-clause =

  qqq> value-expr qqqwqqqqq>qqqqwqq> CONTAINING qqq> value-expr qqq>
                     mqq> NOT qqj

    With CONTAINING, the condition is true if the second value
    expression is found within the first. In most cases, the value
    expressions in a CONTAINING clause evaluate to text strings, but
    CONTAINING also operates on numeric data types.

                                   NOTE

       CONTAINING is not case sensitive; it considers uppercase and
       lowercase forms of the same letter to be a match.

    If either of the value expressions in a CONTAINING clause is
    null, the result is null.
