Question

QQ：

我有一个如下代码可以正常工作，但我还要添加WITH ROLLUP＆amp; WITH CUBE选项（2种不同的情况。）。知道怎么样？在评论我的想法，不幸的是不起作用......

SELECT 
    --ISNULL(EventDate, 'Total'), DOES NOT WORK
    DATEPART(YEAR, EventDate) AS EventYear,
    DATEPART(MONTH, EventDate) AS EventMonth,
    COUNT (*) AS [Number of events]
FROM 
    tblEvent
GROUP BY
    DATEPART(YEAR, EventDate),
    DATEPART(MONTH, EventDate) -- WITH ROLLUP DOESN NOT WORK
ORDER BY
    DATEPART(YEAR, EventDate)DESC, 
    DATEPART(MONTH, EventDate)DESC

Answer 1

尝试：

SELECT 
    --ISNULL(EventDate, 'Total'), DOES NOT WORK
    DATEPART(YEAR, EventDate) AS EventYear,
    DATEPART(MONTH, EventDate) AS EventMonth,
    COUNT (*) AS [Number of events]
FROM 
    tblEvent
GROUP BY ROLLUP(
    DATEPART(YEAR, EventDate),
    DATEPART(MONTH, EventDate))
ORDER BY
    DATEPART(YEAR, EventDate)DESC, 
    DATEPART(MONTH, EventDate)DESC

MS SQL Server - WITH ROLLUP＆amp;通过...分组
