这意味着您需要首先将foreign_key_check设置为禁用，然后需要截断表。语法如下 -
set FOREIGN_KEY_CHECKS = 0;
TRUNCATE TABLE yourTableName1;
TRUNCATE TABLE yourTableName2;
TRUNCATE TABLE yourTableName3;
.
.
.
.
TRUNCATE TABLE yourTableNameN;
set FOREIGN_KEY_CHECKS = 1;现在，从我们的数据库测试中截断一些表。查询如下 −
mysql> set FOREIGN_KEY_CHECKS = 0;
Query OK, 0 rows affected (0.00 sec)
mysql> truncate table skiplasttenrecords;
Query OK, 0 rows affected (0.97 sec)
mysql> truncate table searchtextdemo;
Query OK, 0 rows affected (0.89 sec)
mysql> set FOREIGN_KEY_CHECKS = 1;
Query OK, 0 rows affected (0.00 sec)交叉检查数据是否存在于表中 -
mysql> select *from searchtextdemo;
Empty set (0.00 sec)
mysql> select *from skiplasttenrecords;
Empty set (0.00 sec)空集表示表中没有记录。
