我目前有一个SQL视图,该视图使用以下代码显示自2017年4月以来每天每个团队中有多少人制定了解决方案。我将如何修改它,以便我可以按月而不是每天进行?
SELECT CAST(stat_datetimeresolved as date) as DateResolved, ResolvedByTeam, COUNT(DISTINCT resolvedby) as ResolvedByCnt
FROM [dbo].[Incident]
WHERE Stat_DateTimeResolved >= '20170401'
GROUP BY CAST(Stat_DateTimeResolved as DATE), ResolvedByTeam
ORDER BY CAST(stat_datetimeresolved as DATE) asc, ResolvedByTeam
答案 0 :(得分:0)
您可以设置日期格式,使其仅显示为年份和月份:
select format(getdate(), 'yyyyMM')
然后按此值分组。因此,您的查询应如下所示:
SELECT FORMAT(stat_datetimeresolved, 'yyyyMM') as MonthResolved, ResolvedByTeam, COUNT(DISTINCT resolvedby) as ResolvedByCnt
FROM [dbo].[Incident]
WHERE Stat_DateTimeResolved >= '20170401'
GROUP BY FORMAT(stat_datetimeresolved, 'yyyyMM'), ResolvedByTeam
ORDER BY MonthResolved asc, ResolvedByTeam
更新:对于2012之前的版本,可以使用DATEPART函数构造年份-月份部分。在这种情况下,查询可能如下所示:
SELECT CAST(DATEPART(year, stat_datetimeresolved) as varchar(4)) + '-' + RIGHT('0' + CAST(DATEPART(month, stat_datetimeresolved) as varchar(2)), 2) as MonthResolved, ResolvedByTeam, COUNT(DISTINCT resolvedby) as ResolvedByCnt
FROM [dbo].[Incident]
WHERE stat_datetimeresolved >= '20170401'
GROUP BY CAST(DATEPART(year, stat_datetimeresolved) as varchar(4)) + '-' + RIGHT('0' + CAST(DATEPART(month, stat_datetimeresolved) as varchar(2)), 2), ResolvedByTeam
ORDER BY MonthResolved asc, ResolvedByTeam
或
SELECT convert(char(6), Stat_DateTimeResolved , 112) as MonthResolved, ResolvedByTeam, COUNT(DISTINCT resolvedby) as ResolvedByCnt
FROM [dbo].[Incident]
WHERE Stat_DateTimeResolved >= '20170401'
GROUP BY convert(char(6), Stat_DateTimeResolved , 112), ResolvedByTeam
ORDER BY MonthResolved asc, ResolvedByTeam
