我有以下錯誤代碼如下選擇*:「FROM關鍵字未找到預期」 SELECT *, MAX(Salary)
OVER (PARTITION BY ID_DEPT ORDER BY Salary DESC) R
FROM SG_EMPLOYEES;
但是當我改變與星號每列的名稱一切正常。所以我只想了解背後的原因。
我調查移植含有這樣 count(distinct brand_id) over (partition by user_id order by order_placed_at range between 7 * 24 * 60 * 60 * 1000000 PRECEDING AND 1 PRECEDING) as last_7_day_buyer_brands 對標準SQL的窗口不同的計數一些遺留
我想從表中的3列計算體積並返回唯一的體積。我們有很多行與Width,Height和Length相同,因此我的體積計算自然會有Volume的重複返回值。我認爲,爲了做到這一點,我必須用OVER,PARTITION和CTE的別名不允許在OVER WITH
cteVolume (Id, Volume)
AS
(
SELECT Id, Width * Height * [Length] AS
我有以下數據集: id | date | state
-----------------------
1 | 01/01/17 | high
1 | 02/01/17 | high
1 | 03/01/17 | high
1 | 04/01/17 | miss
1 | 05/01/17 | high
2 | 01/01/17 | mis
