2 个解决方案

#1

Try changing

试着改变

AND DATE_FORMAT('item.purchase_date', '%m %d') LIKE '%09-18%'

来

HAVING DATE_FORMAT(`item`.`purchase_date`, '%m %d') LIKE '%09-18%'

#2

Do not use ' when you are passing column name to the DATE_FORMAT function.

当您向DATE_FORMAT函数传递列名时，不要使用'。

Try with:

试一试:

... AND DATE_FORMAT(item.purchase_date, '%m %d') LIKE '%09-18%'
