mysql自增长id归零

清空具有外键约束的表时报ERROR 1701(42000)的解决

ERROR 1701 (42000): Cannot truncate a table referenced in a foreign key constraint (‘furion’.’tbl_frn_alert’, CONSTRAINT ‘FK353A3CBEB139CC08’
FOREIGN KEY (‘endpt_id’) REFERENCES ‘furion’.’tbl_frn_endpt’(‘id’))

解决方法：

mysql> SET foreign_key_checks=0;

执行

truncate table table_name;

删除后

mysql> SET foreign_key_checks=1;
