SQL：服務器動態PIVOT查詢

應該從下面的查詢中檢索動態客戶的列表。

客戶列表查詢

SELECT 
    Cust_Name 
FROM dbo.Customer 
INNER JOIN dbo.Service 
    ON dbo.Customer.Cust_ID = dbo.Service.Cust_ID 
WHERE [Next_Service] BETWEEN '2017-09-01' AND '2015-09-10'

樞軸查詢

Select * 
from 
(
    select Customer.Cust_Name,Agreementlist.ProductQty,Store.Product_Name as Refill 
    from dbo.Agreement INNER JOIN dbo.Agreementlist ON dbo.Agreement.Agreement_ID = dbo.Agreementlist.Agreement_ID INNER JOIN dbo.Customer 
    ON dbo.Customer.Cust_ID = dbo.Agreement.Cust_ID INNER JOIN Store on Store.Pro_ID = dbo.Agreementlist.ProID where CatID='2' and Agreement.Status='Approved' 

) x 
pivot 
(
    sum(ProductQty) 
    for Cust_Name in ("list of customers resulted from the first query") 
) p

您可以添加一個光標循環你的習慣並將它們添加到變量中。這裏工作。

declare @gruppe nvarchar(max) 
    declare @gruppeSql nvarchar(max) 
    declare @SQL nvarchar(max) 

    DECLARE myCustomers CURSOR FOR 

    SELECT Cust_Name FROM dbo.Customer INNER JOIN dbo.Service 
    ON dbo.Customer.Cust_ID = dbo.Service.Cust_ID 
    WHERE [Next_Service] BETWEEN '2017-09-01' AND '2015-09-10' 

    set @gruppeSql = '' 

    OPEN myCustomers 
    FETCH NEXT FROM myCustomers INTO @gruppe 
    IF (@@FETCH_STATUS>=0) 
    BEGIN 
    SET @gruppeSql = @gruppeSql +'[' [email protected]+']' 
    FETCH NEXT FROM myCustomers INTO @gruppe 
    END 
    WHILE (@@FETCH_STATUS<>-1) 
    BEGIN 
    IF (@@FETCH_STATUS<>-2) 
    SET @gruppeSql = @gruppeSql + ',[' [email protected]+']' 
    FETCH NEXT FROM myCustomers INTO @gruppe 
    END 
    CLOSE myCustomers 
    DEALLOCATE myCustomers 

    SET @gruppeSql = replace(@gruppesql,'''','') 

    --select @gruppeSql 
    SET @SQL = ' 
    Select * 
    from 
    (
    select Customer.Cust_Name,Agreementlist.ProductQty,Store.Product_Name as 
    Refill 
    from dbo.Agreement INNER JOIN dbo.Agreementlist ON 
    dbo.Agreement.Agreement_ID = dbo.Agreementlist.Agreement_ID INNER JOIN 
    dbo.Customer 
    ON dbo.Customer.Cust_ID = dbo.Agreement.Cust_ID INNER JOIN Store on 
    Store.Pro_ID = dbo.Agreementlist.ProID where CatID=''2'' and 
    Agreement.Status=''Approved'' 

) x 
    pivot 
    (
    sum(ProductQty) 
    for Cust_Name in ('[email protected]+') 
) p' 

    print @sql 
    exec(@sql)

錯誤：消息207，級別16，狀態1，行14 無效的列名稱GRUPPE「。 – Ayman

抱歉刪除gruppe - 它來自我的舊SQL - 我只是編輯了行。 – plaidDK

剛剛編輯我的SQL，所以如果您的客戶名稱中有空格，請設置括號。然後我將SQL從SQL中移除到循環中。 – plaidDK

我已經使用這個SQL腳本來創建動態數據透視
