让我们首先创建一个表-

mysql> create table DemoTable828(
   CustomerName varchar(100),
   InterestRate varchar(100)
);

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable828 values('Chris','10%');
mysql> insert into DemoTable828 values('Robert','11.5%');
mysql> insert into DemoTable828 values('David','15.90%');
mysql> insert into DemoTable828 values('Bob','20%');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable828;

这将产生以下输出-

+--------------+--------------+
| CustomerName | InterestRate |
+--------------+--------------+
| Chris        | 10%          |
| Robert       | 11.5%        |
| David        | 15.90%       |
| Bob          | 20%          |
+--------------+--------------+
4 rows in set (0.00 sec)

以下是从MySQL表中的值中删除百分号的查询-

mysql> update DemoTable828 set InterestRate=replace(InterestRate,'%','');
Rows matched: 4 Changed: 4 Warnings: 0

让我们再次检查表记录-

mysql> select *from DemoTable828;

这将产生以下输出-

+--------------+--------------+
| CustomerName | InterestRate |
+--------------+--------------+
| Chris        | 10           |
| Robert       | 11.5         |
| David        | 15.90        |
| Bob          | 20           |
+--------------+--------------+
4 rows in set (0.00 sec)
