要格式化记录,请使用FORMAT()
。让我们首先创建一个表-
mysql> create table DemoTable -> ( -> Price decimal(10,4), -> Rate decimal(10,4) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(1000,10.2); mysql> insert into DemoTable values(2000,20.4); mysql> insert into DemoTable values(100,5);
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+-----------+---------+ | Price | Rate | +-----------+---------+ | 1000.0000 | 10.2000 | | 2000.0000 | 20.4000 | | 100.0000 | 5.0000 | +-----------+---------+ 3 rows in set (0.00 sec)
以下是格式化记录的查询-
mysql> select format((Price * Rate),2) from DemoTable;
这将产生以下输出-
+--------------------------+ | format((Price * Rate),2) | +--------------------------+ | 10,200.00 | | 40,800.00 | | 500.00 | +--------------------------+ 3 rows in set (0.00 sec)
