My database version 5.6.34
I am using case statement like
SELECT
customerName, state, country
FROM
customers
ORDER BY (CASE
WHEN state IS NULL THEN country
ELSE state
END);
table name is customers
I am writting this query in mysql database under SQL, i also attached my table you can see there,
The issue is
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'state IS NULL THEN country     ELSE state END) LIMIT 0, 25' at line 6
it will be really grateful for me if anybody help me please
