FORMAT()
在MySQL中使用以显示货币记录并以正确的形式显示它们。让我们首先创建一个表-
mysql> create table DemoTable -> ( -> Amount DECIMAL(15,4) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(90948484); mysql> insert into DemoTable values(1000000000); mysql> insert into DemoTable values(1535353536); mysql> insert into DemoTable values(773646463);
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-
+-----------------+ | Amount | +-----------------+ | 90948484.0000 | | 1000000000.0000 | | 1535353536.0000 | | 773646463.0000 | +-----------------+ 4 rows in set (0.00 sec)
这是在MySQL中设置货币的查询-
mysql> select concat('USD ',format(Amount,2)) as Currency from DemoTable;
这将产生以下输出。在这里,我们以正确的格式显示USD货币记录-
+----------------------+ | Currency | +----------------------+ | USD 90,948,484.00 | | USD 1,000,000,000.00 | | USD 1,535,353,536.00 | | USD 773,646,463.00 | +----------------------+ 4 rows in set (0.23 sec)
