SELECT   ProductNumber, Category =
      CASE ProductLine
         WHEN 'R' or 'r' THEN 'Road'
         WHEN 'M' or 'm' THEN 'Mountain'
         WHEN 'T' or 't' THEN 'Touring'
         WHEN 'S' or 's' THEN 'Other sale items'
         ELSE 'Not for sale'

My basic requirement is to use ‘OR’ with CASE (if possible) , Please suggest if i am doing anything wrong.

    A different way to write case comes close, but then you have to repeat the variable:

    CASE
  WHEN ProductLine in ('R', 'r') THEN 'Road'
  WHEN ProductLine in ('M', 'm') THEN 'Mountain'

    Or a like character class:

    CASE
  WHEN ProductLine like '[Rr]' THEN 'Road'
  WHEN ProductLine like '[Mm]' THEN 'Mountain'

    Note that in SQL, string comparison is case-insensitive by default. You can alter the default by setting a case-sensitive database collation, but that’s fairly unusual.
