截断表以重置 AUTO_INCREMENT −
truncate table yourTableName;
首先我们创建一个表 −
mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.52 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable values(); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.09 sec)
使用 select 语句显示表中的所有记录 −
mysql> select *from DemoTable;
输出
+----+ | Id | +----+ | 1 | | 2 | | 3 | | 4 | +----+ 4 rows in set (0.00 sec)
以下是重置 AUTO_INCREMENT 的查询 −
mysql> truncate table DemoTable; Query OK, 0 rows affected (0.80 sec) Let us insert some records once again. It will by default begin from 1 for AUTO_INCREMENT: mysql> insert into DemoTable values(); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.09 sec)
显示表中的所有记录 −
mysql> select *from DemoTable;
输出
+----+ | Id | +----+ | 1 | | 2 | +----+ 2 rows in set (0.00 sec)
