各位先進好 ...
小弟有份資料,依下列語法寫出來資料格式SN會連續序號顯示(如:原資料顯示格式)...
但希望是可以依"品號"分別產生SN序號(如:希望資料顯示格式)

原SQL語法
SELECT ROW_NUMBER() OVER (ORDER BY (TD004)DESC)SN, TD004, ONE
FROM(
SELECT (TC001 '-' TC002 '-' TD003)ONE, TD004
FROM bueno002..PURTC B1
INNER JOIN bueno002..PURTD B2
ON TC001=TD001 AND TC002=TD002 AND TD038='2'
WHERE TC014=N'Y' AND TC003 BETWEEN '20170101'AND'20171231' AND (B2.TD200 <> '0' AND B2.TD201 <> '') AND B2.TD004 LIKE '2A%'
)TW
GROUP BY TD004, ONE --TD005,TD006,TD008,TD009,TD010,TD011
ORDER BY TD004 DESC

原資料顯示格式

15 2A340100008 A330-20171130006-0001

希望資料顯示格式

擠成一堆.
發問也不把資料整理好. 你的TDXXX ,亂七八糟的,也捨不得顯示一下.
Table 結構,你的測試資料的 insert 語法也不顯示出來. 是要我們還要幫你生喔.
當然啦,這種毛病也不只你啦.這幾年大概只有一兩個會問的比較好.
看發問的嚴謹程度,就能看出寫程式的用心程度了.

SELECT ROW_NUMBER() OVER (PARTITION BY TD004 ORDER BY (TD004)DESC)SN, TD004, ONE
FROM(
SELECT (TC001 '-' TC002 '-' TD003)ONE, TD004
FROM bueno002..PURTC B1
INNER JOIN bueno002..PURTD B2
ON TC001=TD001 AND TC002=TD002 AND TD038='2'
WHERE TC014=N'Y' AND TC003 BETWEEN '20170101'AND'20171231' AND (B2.TD200 <> '0' AND B2.TD201 <> '') AND B2.TD004 LIKE '2A%'
)TW
GROUP BY TD004, ONE --TD005,TD006,TD008,TD009,TD010,TD011
ORDER BY TD004 DESC

會是這種方式嗎?
可以參考一下我之前記錄的筆記
