问题描述
为什么会出现语法错误
DELETE FROM `print_mailing_request` pmr
INNER JOIN `person` p
ON p.id = pmr.person AND p.email LIKE '%@TEST.COM'
WHERE
pmr.sent_to_fulfiller != 'y'
什么时候可以正常工作而没有错误?
when this works correctly without error?
SELECT * FROM `print_mailing_request` pmr
INNER JOIN `person` p
ON p.id = pmr.person AND p.email LIKE '%@TEST.COM'
WHERE
pmr.sent_to_fulfiller != 'y'
推荐答案
在不使用表别名的情况下，正确的语法如下所示.您缺少要从中删除的表名.
Correct syntax would look like below without using table alias. You are missing the table name to delete from.
DELETE `print_mailing_request`
FROM `print_mailing_request`
INNER JOIN `person`
ON `person`.id = `print_mailing_request`.person
AND `person`.email LIKE '%@TEST.COM'
WHERE `print_mailing_request`.sent_to_fulfiller != 'y'
