SQL SELECT增量批號每X行

Question

我正在嘗試編寫一個SQL SELECT查詢，它有一個每5行增加一個批號的列，我試過在動態行號上使用hacky整數除法，但可以不會繞過第一批次的增量，總是4行而不是5（見圖）。

ROWNUMBER 1-5應該是1，6-10應該是2等。

任何想法如何，我可以做到這一點？

select * ROW_NUMBER() OVER (Order by (select 0)) AS RowNumber, 
1 + convert(int, (ROW_NUMBER() OVER (Order by (select 0))/5)) as BatchNumber, 
* from WorkQueue 

Answer 1

這應該工作：

select ROW_NUMBER() OVER (Order by (select 0)) AS RowNumber, 
(case when convert(int, (ROW_NUMBER() OVER (Order by (select 0)) % 5))=0 then 0 else 1 end) + convert(int, (ROW_NUMBER() OVER (Order by (select 0))/5)) as BatchNumber, 
* from WorkQueue 

Answer 2

試試這個：

SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS RowNumber, 
     CEILING(CAST(ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS DECIMAL(10,2))/5) AS BatchNo, * 
FROM WorkQueue
