MySQL的多张删除错误

Question

我MySQL查询

DELETE data 
    FROM table 
     WHERE DATE_SUB(NOW(), INTERVAL 1 DAY) 
      AND status <> 0; 

，我得到这个错误：

ERROR 1109 (42S02) at line 2: Unknown table 'date' in MULTI DELETE

如何解决这一问题？

Answer 1

data未定义。您可以使用别名或完全删除：

DELETE t 
    FROM table t 
    WHERE DATE_SUB(NOW(), INTERVAL 1 DAY) AND status <> 0; 

或者只是尝试：

DELETE FROM data 
    WHERE DATE_SUB(NOW(), INTERVAL 1 DAY) AND status <> 0;
