MySQL delete 删除
以下是 delete 命令修改 MySQL 数据表数据的通用 SQL 语法:
DELETE FROM table_name [WHERE Clause]
mysql如何要删除一个一行或者多行,用sql语句delete关键词,固定用法 delete from 表名。
1,delete删除一行
delete from student where id=1
2,delete删除多行
delete from student where in (1,2,3)
3,删除表的所有数据
delete from student
注意:在执行delete语句时要带where条件,否则会将表中所有的行都进行删除,非常危险!!
