这是我的SQL查询
SELECT
T0.DocDate, T0.DocNum, T0.TrnspCode, T0.[LicTradNum] as 'Cust Type',
T0.CardName as 'Customer Name', T2.ItemName as 'Item Description',
T1.Quantity , T1.LineTotal as 'Total Sales S$',
(T1.GrssProfit-ISNULL(T1.U_Add_Cost_SGD,0)) as 'Net GP S$',
CASE when T0.TrnspCode =5 then '0' else 80 end as Delivery
FROM
[dbo].[OINV] T0
INNER JOIN
[dbo].[INV1] T1 ON T0.DocEntry = T1.DocEntry
INNER JOIN
[dbo].[OITM] T2 ON T1.ItemCode = T2.ItemCode
INNER JOIN
OITB T3 ON T2.ItmsGrpCod = T3.ItmsGrpCod
INNER JOIN
OSLP T4 ON T0.SlpCode = T4.SlpCode
LEFT OUTER JOIN
OIDC T5 ON T0.Indicator=T5.Code
LEFT OUTER JOIN
OSHP T6 ON T0.TrnspCode = T6.TrnspCode
WHERE
T0.DocType <> 'S'
AND T4.SlpName <> '-No Sales Employee-'
AND T2.ItemName LIKE '%compressed wood%'
AND T0.[LicTradNum] LIKE '%Enno%'
AND year(T0.DocDate) = YEAR(getdate())
AND month(T0.DocDate) = MONTH(getdate())
运行上述查询时的输出：

最后一列，传递，还应该依赖于DocNum行第一次出现在查询中。当DocNum出现在前一行时，我们将返回0，否则我们将根据TrnspCode计算返回值，如查询已经做的那样。
你可以在这个例子中看到DocNum 30072379，第一次出现它必须返回80，而在第二个幻象它应该返回0：
DocDate DocNum TrnspCode Cust Type Customer Name Item Description Quantity Total Sales S$ Net GP S$ Delivery

我尽我所能，可能有效：

这是您的查询，其子查询检查是否已出现DocNum：
SELECT T0.DocDate, T0.DocNum, T0.TrnspCode, T0.[LicTradNum] as 'Cust Type',
T0.CardName as 'Customer Name', T2.ItemName as 'Item Description',
T1.Quantity , T1.LineTotal as 'Total Sales S$',
(T1.GrssProfit-ISNULL(T1.U_Add_Cost_SGD,0)) as 'Net GP S$',
CASE when T0.TrnspCode =5 or exists (select * from OINV T7 where T7.DocNum = T0.DocNum and T7.DocDate < T0.DocDate) then '0'
else 80 end as Delivery
FROM [dbo].[OINV] T0
INNER JOIN [dbo].[INV1] T1 ON T0.DocEntry = T1.DocEntry
INNER JOIN [dbo].[OITM] T2 ON T1.ItemCode = T2.ItemCode
INNER JOIN OITB T3 ON T2.ItmsGrpCod = T3.ItmsGrpCod
INNER JOIN OSLP T4 ON T0.SlpCode = T4.SlpCode
LEFT OUTER JOIN OIDC T5 ON T0.Indicator=T5.Code
LEFT OUTER JOIN OSHP T6 ON T0.TrnspCode = T6.TrnspCode
WHERE T0.DocType <> 'S'
AND T4.SlpName <> '-No Sales Employee-'
