使用DATEADD函数:可以使用DATEADD函数将毫秒部分设置为0,从而删除datetime中的毫秒。示例代码如下: 代码语言:sql 复制 SELECTDATEADD(ms,-DATEPART(ms,your_datetime_column),your_datetime_column)ASdatetime_without_millisecondsFROMyour_table; 使用CONVERT函数:可以使用CONVERT函数将datetime转换为字符类型,然后再转换回date...
在SQL Server中,DATETIME2数据类型可以精确表示日期和时间,包括毫秒。如果我们只关心秒的信息,可以使用CAST函数将DATETIME2类型转换为DATETIME类型。 DECLARE@datetime2DATETIME2=GETDATE()DECLARE@datetimeDATETIMESET@datetime=CAST(@datetime2ASDATETIME)SELECT@datetimeASDateTimeWithoutMilliseconds 1. 2. 3. 4. 5. 6....
有一个有两列的表- DateWithoutMilliseconds和毫秒。这两列一起定义了以毫秒为单位的精确时间戳。 是否有可能编写一条SQL语句(不使用存储过程)来获取具有毫秒精度的最小时间戳的行?实际上,仅仅时间戳就足够了,但是它必须是毫秒,因为几行可能具有相同的DateWithoutMilliseconds值,但以毫秒为单位。现在,我已经完成了在...
