MySQL 如何删除\条目

您可以使用delete命令 –

delete from yourTableName where yourColumnName='\\';

让我们先创建一个表 –

mysql> create table DemoTable
   (
   FolderName varchar(100)
   );
Query OK, 0 rows affected (0.67 sec)

使用插入命令在表中插入一些记录 –

mysql> insert into DemoTable values("????");
Query OK, 1 row affected (0.44 sec)
mysql> insert into DemoTable values("\\");
Query OK, 1 row affected (0.13 sec)

使用select语句显示表中的所有记录-

mysql> select *from DemoTable;
