Is it possible to combine the CASE
statement and the LIKE
operator in a MySQL SELECT
statement?
For Example, I am trying to query a database that stores data in a single column in either one of two formats (this is awful and hurts my head, but I cant change the data so it is what it is.). So sometimes the column numbers
would have data like "6901xxxxxxxx" and sometimes it would have data like "91xxxxxxxxxxx".
What I would like to do is query the data like so -
SELECT
CASE digits
WHEN LIKE "6901%" THEN substr(digits,4)
WHEN LIKE "91%" THEN substr(digits,2)
END as "digits",
FROM raw
This obviously doesn't work but Im hoping its possible.
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
.
