您可以使用delete命令-
delete from yourTableName where yourColumnName='\\\\';
让我们首先创建一个表-
mysql> create table DemoTable ( FolderName varchar(100) );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values("????"); mysql> insert into DemoTable values("\\\\");
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
输出结果
+------------+ | FolderName | +------------+ | ???? | | \\ | +------------+ 2 rows in set (0.00 sec)
这是在MySQL中删除'\\'条目的查询-
mysql> delete from DemoTable where FolderName='\\\\';
让我们从表中检查记录-
mysql> select *from DemoTable;
输出结果
+------------+ | FolderName | +------------+ | ???? | +------------+ 1 row in set (0.00 sec)
