Swap Salary - LeetCode

Given a table salary, such as the one below, that has m=male and f=female values. Swap all f and m values (i.e., change all f values to m and vice versa) with a single update statement and no intermediate temp table.

Note that you must write a single update statement, DO NOT write any select statement for this problem.

After running your update statement, the above salary table should have the following rows:

UPDATE salary
SET sex = CASE 
			WHEN sex = 'f' THEN 'm'
		ELSE 'f' 
	END
