SUBSTRING與條件

Question

我想有這個+3申請時paymentterm如果小於45

我當前的代碼是：

SELECT 
    [course_title], 
    sblPOAmount, 
    SBLInvoiceDate, 
    paymentTerm, 
    DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) 
FROM 
    [A_Sys].[dbo].[Eventtbl] 
WHERE 
    DATENAME(MONTH, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) = 'June' 
    AND DATENAME(YEAR, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) = '2017' 

＃ 的額頭聲明（摘要）

SELECT 
SUM(sblPOAmount) AS totalPOAmt, 
case 
    when paymentTerm = '45 Days' 
    then DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) 
    else DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 0, SBLInvoiceDate)) 
end 
FROM 
[A_Sys].[dbo].[Eventtbl] 
WHERE DATENAME(MONTH, DATEADD(day,SUBSTRING(paymentTerm, 1, 2)+3,SBLInvoiceDate))='June' 
AND DATENAME(YEAR, DATEADD(day,SUBSTRING(paymentTerm, 1, 2)+3,SBLInvoiceDate))='2017' 
Group By paymentTerm,SBLInvoiceDate 

＃

目前，我不能夠通過

由於總結到組 ＃

當前輸出： + ----- + --- + | 10.60 | 23 | | 0.00 | 24 | | 10.50 | 14 | + --------- +

你正在尋找一個case語句...基礎上

SELECT 
    [course_title], 
    sblPOAmount, 
    SBLInvoiceDate, 
    paymentTerm, 
    case 
     when paymentTerm < 45 then DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) 
     else DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2), SBLInvoiceDate)) 
    end 
FROM 
    [A_Sys].[dbo].[Eventtbl] 
WHERE 
    DATENAME(MONTH, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) = 'June' 
    AND DATENAME(YEAR, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) = '2017' 

編輯

SELECT 
    [course_title], 
    sum(sblPOAmount), 
    SBLInvoiceDate, 
    paymentTerm, 
    case 
     when paymentTerm < 45 then DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) 
     else DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2), SBLInvoiceDate)) 
    end 
FROM 
    [A_Sys].[dbo].[Eventtbl] 
WHERE 
    DATENAME(MONTH, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) = 'June' 
    AND DATENAME(YEAR, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) = '2017' 
GROUP BY 
    [course_title], 
    SBLInvoiceDate, 
    paymentTerm, 
    case 
     when paymentTerm < 45 then DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2) + 3, SBLInvoiceDate)) 
     else DATENAME(Day, DATEADD(day, SUBSTRING(paymentTerm, 1, 2), SBLInvoiceDate)) 
    end
