MySQL Case in Select Statement with LIKE operator

Question

Is it possible to combine the CASE statement and the LIKE operator in a MySQL SELECT statement?

For Example, I am trying to query

Answer 1

Using the second form of CASE should work:

SELECT
  CASE
    WHEN digits LIKE '6901%' THEN substr(digits,4)
    WHEN digits LIKE '91%' THEN substr(digits,2)
  END as digits
FROM raw

Furthermore, you have a stray comma at the end of your SELECT.
