 SQL根据指定月份获取当前季度

declare @dt datetime
set @dt = cast('2007-05-01' as datetime)

select datename(yy,@dt) + '-' + right('0'+cast(3 * (datepart(qq,@dt)-1) + 1 as varchar),2) + '月'
union 
select datename(yy,@dt) + '年' + right('0'+cast(3 * (datepart(qq,@dt)-1) + 2 as varchar),2) + '月'
union
select datename(yy,@dt) + '年' + right('0'+cast(3 * (datepart(qq,@dt)-1) + 3 as varchar),2) + '月'

 sql format 格式化数字(前面补0)

以下是详细分析：
　　1、select power(10,3)得到1000
　　2、select cast(1000+33 as varchar） 将1000转换类型
　　3、select right(100033,3) 从右边取3个字符得到033
　　最后结果是:
　　select right(cast(power(10,3) as varchar)+33,3)
