sql分类汇总及Select的自增长脚本

如图:

其中Num是自增长列,Operation是分类标签,count是汇总数据

脚本如下:

select Num=row_number() OVER(order BY HT_Resv.OperationStatus),HT_Resv.OperationStatus ,
CASE HT_Resv.OperationStatus
WHEN '3' THEN '成功'
WHEN '4' THEN '失败'
end as 'Status',count(HT_Resv.Id) as 'Count'
FROM ht_resv group BY HT_Resv.OperationStatus
