Format SQL Server 2012 Time(7) to “HH:mm”

问题

I have Time(7) columns for each day in the week and I want to format it as HH:mm

I tried to use SQL Server 2012 new FORMAT function, but it only shows the NULL value.

How can I format a time(7) datatype to display as HH:mm?

回答1:

You should always format your data in the presentation layer. If there are circumstance where the TIME datatype cannot be formatted by your UI, you can cast the value to a DATETIME which will more than likely be supported.

SELECT CAST(TimeColumn AS DATETIME)
FROM MyTable

回答2:

You can use Format in Ms-sql To Get Format of Time as you Need

Example :

SELECT Format(GETDATE(), 'hh:mm')

Output :

07:52

For You Columns You can Replace GETDATE() with your column name as below -

Example :

SELECT Format(HourMonday, 'hh:mm')

回答3:

DECLARE @mytime Time(7)
set  @mytime=GETDATE()
select SUBSTRING(CONVERT(CHAR(50),CAST(@mytime as time)),1,5)

回答4:

Just to add a bit to the already chosen answer.

Since you are using Reporting Services you can do the formatting with Format():

=Format(Now(), "hh:mm")

回答5:

SELECT left(TimeColumn,5) as Time
FROM MyTable

回答6:

Format does work on time(7), but you have to escape the colon and hh mm are lower case.

Declare @HourMonday as  time(7) = '13:45:00'

Select FORMAT(@HourMonday, N'hh\:mm')
