Question

我有一张桌子，我需要根据发票上的月份创建三个总和。

总和是使用＆＃39; invoice_number＆＃39;的前三个字母计算的。字段，然后添加所有＆＃39; Invoice_Amount＆＃39;对于该特定发票类型。

数据示例 Invoice_Number - MSP-1111 发票金额 - $ 2100.00

我想基于几个月来计算这个，所以它格式化为例子

Year | Month | Total MSP Invoices| Total PS Invoices | Total App Invoice

我能够获得这些月份，但是所有月份的总数是相同的，而不是特定于那个月。以下是我正在使用的查询。

我想显示最近12个月。

select year(date_invoice) as Year, 
    Case month(date_invoice)
        When 1 Then 'Jan'
        When 2 Then 'Feb'
        When 3 Then 'March'
        When 4 Then 'April'
        When 5 Then 'May'
        When 6 Then 'June'
        When 7 Then 'July'
        When 8 Then 'Aug'
        When 9 Then 'Sept'
        When 10 Then 'Oct'
        When 11 Then 'Nov'
        When 12 then 'Dec' 
    End 
as Month,
(Select sum(invoice_amount) from invoices where Invoice_number like 'MSP%') as 'MSP',
(Select sum(invoice_amount) from invoices where Invoice_number like 'PS%') as'PS',
(Select sum(invoice_amount) from invoices where Invoice_number like 'APP%') as 'App'
from invoices
Where convert(nvarchar(50), date_invoice,100) > DATEADD(month, -12,  getdate())
Group by year(date_invoice), month(date_invoice)
Order by year(date_invoice), month(date_invoice)

任何帮助都会很棒！

Answer 1

您应该能够使用组中的case语句将其组合正确

 select year(date_invoice) as Year, 
Case month(date_invoice)
    When 1 Then 'Jan'
    When 2 Then 'Feb'
    When 3 Then 'March'
    When 4 Then 'April'
    When 5 Then 'May'
    When 6 Then 'June'
    When 7 Then 'July'
    When 8 Then 'Aug'
    When 9 Then 'Sept'
    When 10 Then 'Oct'
    When 11 Then 'Nov'
    When 12 then 'Dec' 
End 
as Month,
 (Select sum(invoice_amount) from invoices where Invoice_number like 'MSP%') as 'MSP',
 (Select sum(invoice_amount) from invoices where Invoice_number like 'PS%') as'PS',
 (Select sum(invoice_amount) from invoices where Invoice_number like 'APP%') as 'App'
 from invoices
 Where convert(nvarchar(50), date_invoice,100) > DATEADD(month, -12,  getdate())
 Group by year(date_invoice),  Case month(date_invoice)
    When 1 Then 'Jan'
    When 2 Then 'Feb'
    When 3 Then 'March'
    When 4 Then 'April'
    When 5 Then 'May'
    When 6 Then 'June'
    When 7 Then 'July'
    When 8 Then 'Aug'
    When 9 Then 'Sept'
    When 10 Then 'Oct'
    When 11 Then 'Nov'
    When 12 then 'Dec' 
End 
Order by year(date_invoice), month(date_invoice)

Answer 2

有一个派生表，您可以在其中放置CASE表达式来获取月份名称。

使用CASE表达式执行条件SUM。

select year, month,
       sum(case when Invoice_number like 'MSP%' then invoice_amount end) as 'MSP',
       sum(case when Invoice_number like 'PS%' then invoice_amount end) as 'PS',
       sum(case when Invoice_number like 'APP%' then invoice_amount end) as 'APP'
from
(
select date_invoice,
       Invoice_number
       year(date_invoice) as Year, 
       case month(date_invoice)
         When 1 Then 'Jan'
         When 2 Then 'Feb'
         When 3 Then 'March'
         When 4 Then 'April'
         When 5 Then 'May'
         When 6 Then 'June'
         When 7 Then 'July'
         When 8 Then 'Aug'
         When 9 Then 'Sept'
         When 10 Then 'Oct'
         When 11 Then 'Nov'
         When 12 then 'Dec' 
       End as Month,
       invoice_amount
from invoices
where convert(nvarchar(50), date_invoice,100) > DATEADD(month, -12,  getdate())
) as dt
Group by year, month
Order by year, month

Answer 3

选择年，月， sum（Invoice_number喜欢＆＃39; MSP％＆＃39;然后invoice_amount结束）为＆＃39; MSP＆＃39;，总和（Invoice_number喜欢＆＃39; PS％＆＃39;然后invoice_amount结束时的情况）为＆＃39; PS＆＃39;，总和（Invoice_number喜欢＆＃39; APP％＆＃39;然后invoice_amount结束）的情况为＆＃39; APP＆＃39; 从（选择date_invoice，发票编号年（date_invoice）为年，案例月（date_invoice）当1然后＆＃39; Jan＆＃39; 当2然后＆＃39; 2月＆＃39; 当3然后＆＃39;三月＆＃39; 当4然后＆＃39;四月＆＃39; 当5然后＆＃39;五月＆＃39; 当6然后＆＃39;六月＆＃39; 当7然后＆＃39; 7月＆＃39; 当8然后＆＃39; 8月＆＃39; 当9然后＆＃39; 9月＆＃39; 当10然后＆＃39; 10月＆＃39; 什么时候11然后＆＃39; 11月＆＃39; 什么时候12，然后'12月＆＃39; 以月结束， INVOICE_AMOUNT 从发票其中convert（nvarchar（50），date_invoice，100）＆gt; DATEADD（月，-12，getdate（）））作为dt 按年，月分组按年，月排序
