How to get time part from SQL Server 2005 datetime in 'HH:mm tt' format

Question

How to get time part from SQL Server 2005 datetime in HH:mm tt format

E.g.

11:25 AM
14:36 PM

Answer 1

一种方法是:

SELECT LTRIM(RIGHT(CONVERT(VARCHAR(20), GETDATE(), 100), 7))

如果您在这里查看联机丛书,格式100是具有您想要的格式的时间元素的格式,它只是从前面剥离日期的情况.

Answer 2

你需要两个转换器,一个用于获得HH:mm时间,一个用于获得AM/PM.例如:

declare @date datetime
set @date = '20:01'
SELECT CONVERT(VARCHAR(5), @date, 108) + ' ' +
       SUBSTRING(CONVERT(VARCHAR(19), @date, 100),18,2)

这打印:

20:01 PM

在选择查询中,将@date替换为列的名称.

Answer 3

SQL Server 2008

SELECT
CONVERT(TIME,GETDATE()) AS HourMinuteSecond,
CONVERT(DATE,GETDATE(),101) AS DateOnly
GO

结果

HourMinuteSecond: 13:06:56.5770000
DateOnly:         2012-07-26

SQL Server 2000/2005

SELECT
CONVERT(VARCHAR(8),GETDATE(),108) AS HourMinuteSecond,
CONVERT(VARCHAR(8),GETDATE(),101) AS DateOnly
GO
