I have two columns (Please check the image) based on which I want to create a third column stating that they are a 'match'
col 1 | col 2 | Match column |
---|---|---|
MA;NY | NY | Match |
MA;NY | FL | Un-match |
KS | AR;KY;LA;MS | Un-Match |
KY | AR;KY;LA;MS | Match |
However, both the columns are off a 'picklist' data type and I am not sure how to perform that in mysql.
P.S Both the columns have multiple entries with a delimiter as ';', so the logic go true in both cases. col 1 to col 2 and col 2 to col 1
I tried using
SELECT col 2 IN (SELECT col 1 from table 1) FROM table 2
however, it only works on some records (strange)
If you have a list of values in either (but not both) col1 or col2 then you can do:
select
col1,
col2,
find_in_set(col1, replace(col2, ';', ',')) or
find_in_set(col2, replace(col1, ';', ','))
from t;
