上週Damir Sudarevic在此社區幫助查詢此查詢以生成seq編號。 我有一個與這個問題的幾個問題。由於某些原因,OrderDetailsID不會顯示記錄,儘管按順序指定它。如下圖所示SQL Server序列號問題
Seq SeqNO
1A 1
2A 2
2B 2A
2C 2B
3A 3
3B 3A
3C 3B
相反,我怎麼得到它
在下面序列和SEQNO顯示記錄的查詢中的兩列如下圖所示
SeqNo
1
2A
2B
2C
3A
3B
3C
WITH OrderDetails
AS (SELECT prodcode
,prodDesc
,orderID
,OrderDetailID
,DENSE_RANK() OVER (ORDER BY prodCode) AS [RnkSeq]
,ROW_NUMBER() OVER (PARTITION BY prodCode ORDER BY OrderDetailID) AS [NumSeq]
FROM OrderDetails where orderID=65303
)
SELECT OrderDetailID
,prodcode
,CAST(RnkSeq AS varchar(10)) + CHAR(64 + NumSeq) as Seq
,Replace(CAST(RnkSeq AS varchar(10)) + CHAR(63 + NumSeq),'@','') AS SeqNo
,orderID
FROM OrderDetails
Lucero,它不存在於我發佈的查詢中,但是,即使我添加它也不顯示OrderDetailsID的順序 – acadia 2010-01-28 15:21:16
