我使用此方案进行多次删除
DELETE Table1, Table2, Table3
FROM Table1
JOIN Table2 ON (Table2.ConditionID = Table1.ConditionID)
JOIN Table3 ON (Table3.ConditionID = Table2.ConditionID)
WHERE Table1.ConditionID = ?;
为什么我不能使用这样的别名
DELETE Table1, Table2, Table3
FROM Table1 t1
JOIN Table2 t2 ON (t2.ConditionID = t1.ConditionID)
JOIN Table3 t3 ON (t3.ConditionID = t2.ConditionID)
WHERE t1.ConditionID = ?;
我只得到一个正常的语法错误。
最佳答案
实际上可以,只需使用 DELETE
关键字后面给出的 ALIAS
名称即可。
DELETE t1, t2, t3
FROM Table1 t1
JOIN Table2 t2 ON (t2.ConditionID = t1.ConditionID)
JOIN Table3 t3 ON (t3.ConditionID = t2.ConditionID)
WHERE t1.ConditionID = ?;
关于mysql - mysql 中的多个 DELETE 不适用于别名,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/15971337/
