I am trying to write a formula in ETL to change a column the has for example
"Los Angeles, CA 90001" to preview as just "CA"
If the comma is consistent in your data, you can use the split_part function along with the left and trim functions to get this. It would look like this:
TRIM(LEFT(SPLIT_PART(`addressfield`,',',2),3))
Hope this helps
Alternatively if your field may not have a comma but still has spaces surrounding two uppercase letters you can use a regular expression to find and replace your string:
REGEXP_REPLACE(`addressfield`, '^.* ([A-Z]{2}) .*$', '$1')
use splitpart to split the text strong on the comma delimiter
split_part(`addressfield`, ',', 2)
wrap those results in a trim to remove any leading whitespaces.
then split_part on the space and keep the first result in the array
