如何重置 MySQL 表格的自动递增列
原标题:How to reset auto increment column of a table in MySQL

我有一个表格, 它第一列 < code> sl < /code > 是自动递增。 在填充我的表格后, 我删除了前两行, 第一个条目是 < code> sl 1。 是否可以将它重置为 1 个维护 AI? 我使用 PHP MyAdmin 。

最佳回答

我不知道我是否得到了您的问题, 但如果您想要重新编号您的列 sl , 请重新编号您的列 > ALTER Table your_table DROP sl , 然后 > ALTER Table your_table ADDs sl your_ 定义

问题回答
ALTER TABLE tablename AUTO_INCREMENT = 1;

如果您只想将自动编号重置回 1 , 您可以同时使用 :

DBCC CHECKIDENT (tablename, RESEED, 0)

TRUNCATE TABLE tablename

第一个选项将简单重置您的 auto-number count , 而第二个选项将清除您的表格中的所有数据并重置计数器 。

这就是你问的吗?

尝试使用 ALTER 表格Name AUTO_INCROONT=0; 。 下一个记录将输入索引 1 。
