MYSQL中delete删除多表数据

我的mysql版本如下：【版本不是很低】
Server version: 5.0.45-log Source distribution

从数据表deltable中把那些值在数据表Statistic里有匹配的记录全删除掉

delete deltable from deltable a ,Statistic b where b.Date=a.Date and b.Server=a.Server and b.`Key`=a.`Key` and b.SubKey=a.SubKey;

看看这条语句没有任何问题吧，就是运行不出来结果

我看了一些官方文档，大多数说法如下：

1、从数据表t1中把那些id值在数据表t2里有匹配的记录全删除掉

DELETE t1 FROM t1,t2 WHERE t1.id=t2.id 或DELETE FROM t1 USING t1,t2 WHERE t1.id=t2.id

2、从数据表t1里在数据表t2里没有匹配的记录查找出来并删除掉

DELETE t1 FROM t1 LEFT JOIN T2 ON t1.id=t2.id WHERE t2.id IS NULL 或

DELETE FROM t1,USING t1 LEFT JOIN T2 ON t1.id=t2.id WHERE t2.id IS NULL

3、从两个表中找出相同记录的数据并把两个表中的数据都删除掉

DELETE t1,t2 from t1 LEFT JOIN t2 ON t1.id=t2.id WHERE t1.id=25

注意此处的delete t1,t2 from 中的t1,t2不能是别名

如：delete t1,t2 from table_name as t1 left join table2_name as t2 on t1.id=t2.id where table_name.id=25 在数据里面执行是错误的（MYSQL 版本不小于5.0在5.0中是可以的）

上述语句改写成

delete table_name,table2_name from table_name as t1 left jointable2_name as t2 on t1.id=t2.id where table_name.id=25在数据里面执行是错误的（MYSQL 版本小于5.0在5.0中是可以的）

附：上述语句运行的环境 MYSQL 4.0.2以上

最后取消别名以后：
mysql> delete from deltable using deltable ,s_tmp where deltable.Date=s_tmp.Date and deltable.Server=s_tmp.Server and deltable.`Key`=s_tmp.`Key` and deltable.SubKey=s_tmp.SubKey;
Query OK, 1630 rows affected (48.51 sec)

mysql> select count(*) from s_tmp;
+----------+
| count(*) |
+----------+
| 1642 |
+----------+
1 row in set (0.00 sec)

是不是涉及到的多表删除都不能使用别名呢
