带有OR的mysql SELECT IF语句

Question

以下作品 - 当退单等于1时返回Y，否则默认为N

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

然而，我似乎无法让这个工作？语法是否有效

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

Answer 1

据推测这可行：

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

Answer 2

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

将按照Buttle Butkus的建议完成工作。
