我需要从timestamp列舍入到NEAREST月初(以时间戳格式).
怎么做到这一点?
例子:
TimestampColumn A: Rounded to these values
2012-01-07 18:18:29.923 2012-01-01 00:00:00.000
2012-01-14 12:58:13.122 2012-01-01 00:00:00.000
2012-06-09 17:10:30.787 2012-06-01 00:00:00.000
2012-05-31 09:29:43.870 2012-06-01 00:00:00.000
2012-10-22 12:09:47.067 2012-11-01 00:00:00.000
2012-10-15 04:35:11.013 2012-10-01 00:00:00.000
最佳答案 考虑先转换为日期
DECLARE @d DATETIME
set @d = CONVERT(DATE, '2012-02-14 12:58:13.122')
SET @d = DATEADD(DAY, 1-datepart(day, @d), @d)
SELECT @d
