mysql SELECT IF 语句与 OR

Question

以下工作 - 当退款等于 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

大概这会起作用:

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