带有OR的mysql SELECT IF语句

Question

以下工作 - 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

但是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

大概这可行:

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

将会像Buttle Butkus所做的那样完成工作.
