我有 3 个表(出于某种原因我需要将它们分成 3 个表，我只是使用 LEFT JOIN 连接它们)
表1
refno
location
表2
refno
description
表3
refno
imagepath
要删除，我需要发出 3 条 DELETE 语句
DELETE FROM table1 WHERE refno = 'variablehere'
DELETE FROM table2 WHERE refno = 'variablehere'
DELETE FROM table3 WHERE refno = 'variablehere'
有没有办法使用单个 DELETE 语句从 3 个表中删除，我的意思是我可以在 DELETE 语句中使用类似 LEFT JOIN 的东西吗？
最佳答案
SQL Fiddle显示以下查询的示例:
DELETE a.*, b.*, c.*
FROM table1 AS a, table2 AS b, table3 AS c
WHERE a.refno = b.refno
AND b.refno = c.refno
AND a.refno = 'variablehere'
关于mysql - 使用单个 Delete 语句删除多个表，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24015366/
