的SQL Server CTE查詢語法錯誤

Question

我得到這個錯誤

消息102，級別15，狀態1，行1個
附近有語法錯誤 '='。

從該查詢：

seq = row_number() over 
(
    partition by t.CustID 
    order by t.InvoiceID, 
      t.Date, 
      CASE WHEN t.S_Type = 'Receipt Voucher' THEN 1 ELSE 2 END 
) 

; 

WITH cte 
AS (
    SELECT CustID, 
     [InvoiceID], 
     S_Type, 
     DATE, 
     Debit, 
     Credit, 
     seq = row_number() OVER (
      PARTITION BY CustID 
      ORDER BY InvoiceID, 
       DATE, 
       CASE 
        WHEN S_Type = 'Receipt Voucher' 
         THEN 1 
        ELSE 2 
        END 
      ) 
    FROM Statement 
    ) 
SELECT c.[InvoiceID], 
    c.S_Type AS Type, 
    c.DATE, 
    c.Debit, 
    c.Credit, 
    b.Balance 
FROM cte c 
CROSS APPLY (
    SELECT Balance = SUM(Debit) - SUM(Credit) 
    FROM cte AS x 
    WHERE x.CustID = c.CustID 
     AND x.seq <= c.seq 
    ) b 
WHERE c.CustID = '48' 
    AND DATE BETWEEN '2015-01-01' 
     AND '2016-01-01' 
ORDER BY seq 

我已嘗試添加選擇在前期序列的我得到這些錯誤：

消息4104，級別16，狀態1，3號線
無法綁定多部分標識符「t.CustID」。

Msg 4104，Level 16，State 1，Line 4

您在請求開始時有一段代碼seq=...，這是無效的。您的查詢可以使用在cte中計算的seq。

WITH cte 
AS (
    SELECT CustID, 
     [InvoiceID], 
     S_Type, 
     DATE, 
     Debit, 
     Credit, 
     seq = row_number() OVER (
      PARTITION BY CustID 
      ORDER BY InvoiceID, 
      DATE, 
      CASE 
       WHEN S_Type = 'Receipt Voucher' 
        THEN 1 
       ELSE 2 
       END 
      ) 
    FROM Statement 
    ) 
SELECT c.[InvoiceID], 
    c.S_Type AS Type, 
    c.DATE, 
    c.Debit, 
    c.Credit, 
    b.Balance 
FROM cte c 
CROSS APPLY (
    SELECT Balance = SUM(Debit) - SUM(Credit) 
    FROM cte AS x 
    WHERE x.CustID = c.CustID 
     AND x.seq <= c.seq 
    ) b 
WHERE c.CustID = '48' 
    AND DATE BETWEEN '2015-01-01' 
    AND '2016-01-01' 

ORDER BY c.seq; 

還有借記之前缺少Ç。
