Question

我收到此错误

Msg 102，Level 15，State 1，Line 1
＆＃39; =＆＃39;附近的语法不正确。

来自此查询：

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

我试图在seq前面添加select我得到这些错误：

Msg 4104，Level 16，State 1，Line 3
  多部分标识符＆＃34; t.CustID＆＃34;无法受约束。

Msg 4104，Level 16，State 1，Line 4
  多部分标识符＆＃34; t.InvoiceID＆＃34;无法受约束。

Msg 4104，Level 16，State 1，Line 5
  多部分标识符＆＃34; t.Date＆＃34;无法受约束。

Msg 4104，Level 16，State 1，Line 6
  多部分标识符＆＃34; t.S_Type＆＃34;无法受约束。

Msg 4104，Level 16，State 1，Line 34
  多部分标识符＆＃34; .Debit＆＃34;无法受约束。

您的请求seq=...开头的代码片段无效。您的查询可以使用cte。

中计算的 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;

在借记之前还有一个 c 缺失。
