Hi,
In the following statement, does the custom function get executed twice?
SELECT
MY_FUNCTION(...),
CASE WHEN MY_FUNCTION(...) = '...' THEN '...' ELSE '...' END
...
...
If so, is there a way I can make it execute once? I tried this but it gave me a "Column my_function does not exist" error.
SELECT
MY_FUNCTION(...) AS my_function,
CASE WHEN my_function = '...' THEN '...' ELSE '...' END
...
...
Thank you in advance.
