Question

我想编写查询以按当前日期和每月计算金额。

我的费用表中有 TransactionID，Date，Amount 列。

我想要这种格式：

currentDayAmount              TotalMonthlyAmount
$12305                        $236589                  --suppose on 31 Aug 2011
$62598                        $365489                  --suppose on 30 Sep 2011

此处CurrentDayAmount是我输入以执行查询的日期，TotalMonthlyAmount是我输入日期的月份。这意味着我想要执行三个日期。首先是我要运行查询的那一天，最后两个是日期范围，需要每月总金额。我执行以下查询但显示正确的数据但显示在行中。

select sum(c.amount) 
from charge c 
where c.eDate between '09/16/2011' and '09/17/2011'
union all 
select sum(c1.amount) 
from charge c1
where c1.eDate between '09/01/2011' and '09/20/2011'

结果

$33256.25
$705826.36

我希望这些数据在列中

current            Monthly
$33256.25          $705826.36

我希望这些信息足以让我了解我想做的事情请提出任何建议或疑问以解决我的问题。

提前致谢

Answer 1

略有不同的方法：

SELECT SUM(CASE 
             WHEN c.edate BETWEEN '09/16/2011' AND '09/17/2011' THEN c.amount 
             ELSE 0 
           END), 
       SUM(CASE 
             WHEN c.edate BETWEEN '09/01/2011' AND '09/20/2011' THEN c.amount 
             ELSE 0 
           END), 
FROM   charge c

试试这个：

SELECT
    currentDayAmount = (
                         SELECT
                            SUM(c.amount)
                         FROM
                            charge c
                         WHERE
                            c.eDate BETWEEN '09/16/2011' AND '09/17/2011'
                       )
  , TotalMonthlyAmount = (
                           SELECT
                            SUM(c1.amount)
                           FROM
                            charge c1
                           WHERE
                            c1.eDate BETWEEN '09/01/2011' AND '09/20/2011'
                         )
