mysql SELECT IF statement with OR

Question

The following works - returns Y when chargeback equal to 1 else it defaults to N

IF(fd.charge_back = 1, 'Y', 'N') AS charge_back

however I cannot seem to get this one working? Is the syntax valid

IF(compliment = ('set' OR 'Y' OR 1), 'Y', 'N') AS customer_compliment

Solution 1

Presumably this would work:

IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment

Solution 2

IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment

Will do the job as Buttle Butkus suggested.
