将数字格式化为货币金额

Question

我想为我的 SQL 比萨餐厅数据库创建一个 "sales report"。当我尝试使用 sum(order_amount) 运行 SELECT 查询时，该列未格式化。我正在使用 Oracle SQL。这是代码：

column order_amount heading "Order Amount" format ',999,999.00';
select order_id, count(order_id) as "Number of Orders", sum(pizza_quantity) as "Pizzas Sold", 
sum(order_amount) as "Total Profit"
from order_details group by order_id;

这是输出：

SQL> select order_id, count(order_id) as "Number of Orders",sum(pizza_quantity) as "Pizzas Sold",
  2  sum(order_amount) as "Total Profit"
  3  from order_details group by order_id;

  Order ID Number of Orders Pizzas Sold Total Profit
---------- ---------------- ----------- ------------
         1                2           5          105
         6                1           2           20
         2                2           6          165
         4                2          12          130
         5                2           6           80
         8                1           7          140
         3                2           4           80
         7                1           6          120
         9                1           8          120
        10                1           9          270

10 rows selected.

有什么方法可以将总利润列显示为货币格式？

Answer 1

您可以尝试使用 to_char()。

...
to_char(sum(order_amount), ',999,999.00')
...

Answer 2

您可以使用 数字格式建模元素 作为 FML9,999.99 或 G990D00 作为 to_char 函数的第二个参数，如下例所示:

SQL> alter session set nls_currency='$';
SQL> alter session set NLS_NUMERIC_CHARACTERS = '.,';
SQL> with tab(order_ID,order_amount) as
  (
    select 1,255.51 from dual union all
    select 1,750.33 from dual union all    
    select 6,420.39 from dual union all
    select 2,790.00 from dual union all
    select 2,375.05 from dual    
  )
  select to_char(sum(order_amount),'FML9,999.99') as "Total Profit" 
    from tab
   group by order_ID  
  union all
  select to_char(sum(order_amount),'G990D00') as "Total Profit" 
    from tab
   group by order_ID

Total Profit
,005.84
0.39
,065.05
 ,005.84
   0.39
   ,065.05

如果您的问题具体是关于 SQL*Plus 列格式，问题是您为名为 order_amount 的列定义了格式，但在查询中它被称为 "Total Profit":

column order_amount heading "Order Amount" format ',999,999.00'

如果您更改查询以便将所需的列命名为 order_amount，则将使用定义的格式：

select order_id, count(order_id) as "Number of Orders", sum(pizza_quantity) as "Pizzas Sold"
     , sum(order_amount) as order_amount
from   order_details
group by order_id;

（顺便说一句，除非您的成本为零，否则我怀疑总订单金额是否全是利润，在这种情况下我想投资您的披萨业务。）
