Solved ETL - Replace Null Values
Hi,
I have a dataset with null values and text and I am trying to replace them with 0 and 1 respectively. But, when I try to write a formula using the conditions 'If Null' or 'If not null' I keep getting errors.
Does anyone have any ideas?
Thanks!
Edit: I figured out what I was doing wrong.

There are really a few ways you could do this:
Option 1 - check for nulls
CASE WHEN fieldname IS NULL THEN 0 ELSE 1 END
Option 2 - change nulls to 0 then check for 0
CASE WHEN IFNULL(fieldname,0) = 0 THEN 0 ELSE 1 END
Option 3 - check for text using the length function
CASE WHEN LENGTH(TRIM(fieldname)) >= 1 THEN 1 ELSE 0 END
There are probably more options, but there are a few for you.
