Konwertuj typ danych czasu do formatu AM PM:

W SQL 2012 można użyć funkcji Format ().

Pomiń odlewanie, jeśli typem kolumny jest (datetime).

Przykład:

SELECT FORMAT(StartTime,'hh:mm tt') AS StartTime
FROM TableA

Oto różne sposoby, w jakie możesz to wyciągnąć (w zależności od potrzeb).

Using the Time DataType:

DECLARE @Time Time = '15:04:46.217'
SELECT --'3:04PM'
       CONVERT(VarChar(7), @Time, 0),

       --' 3:04PM' --Leading Space.
       RIGHT(' ' + CONVERT(VarChar(7), @Time, 0), 7),

       --' 3:04 PM' --Space before AM/PM.
       STUFF(RIGHT(' ' + CONVERT(VarChar(7), @Time, 0), 7), 6, 0, ' '),

       --'03:04 PM' --Leading Zero.  This answers the question above.
       STUFF(RIGHT('0' + CONVERT(VarChar(7), @Time, 0), 7), 6, 0, ' ')

       --'03:04 PM' --This only works in SQL Server 2012 and above.  :)
       ,FORMAT(CAST(@Time as DateTime), 'hh:mm tt')--Comment out for SS08 or less.

Using the DateTime DataType:

DECLARE @Date DateTime = '2016-03-17 15:04:46.217'
SELECT --' 3:04PM' --No space before AM/PM.
       RIGHT(CONVERT(VarChar(19), @Date, 0), 7),

       --' 3:04 PM' --Space before AM/PM.
       STUFF(RIGHT(CONVERT(VarChar(19), @Date, 0), 7), 6, 0, ' '),

       --'3:04 PM' --No Leading Space.
       LTRIM(STUFF(RIGHT(CONVERT(VarChar(19), @Date, 0), 7), 6, 0, ' ')),

       --'03:04 PM' --Leading Zero.
       STUFF(REPLACE(RIGHT(CONVERT(VarChar(19), @Date, 0), 7), ' ', '0'), 6, 0, ' ')

       --'03:04 PM' --This only works in SQL Server 2012 and above.  :)
       ,FORMAT(@Date, 'hh:mm tt')--Comment line out for SS08 or less.

SELECT CONVERT(varchar, StartTime, 100) AS ST,
       CONVERT(varchar, EndTime, 100) AS ET
FROM some_table

Lub

SELECT RIGHT('0'+ LTRIM(RIGHT(CONVERT(varchar, StartTime, 100),8)),8) AS ST,
       RIGHT('0'+ LTRIM(RIGHT(CONVERT(varchar, EndTime, 100),8)),8) AS ET
FROM some_table

select case 
      when DATEPART(hour,'17:30:00.0000000') > 12 
      then cast((DATEPART(hour,'17:30:00.0000000') - 12) as varCHAR(2)) + ':' + cast(DATEPART(minute,'17:30:00.0000000') as varCHAR(2)) + ' PM'
      else cast(DATEPART(hour,'17:30:00.0000000') as varCHAR(2)) + ':' + cast(DATEPART(minute,'17:30:00.0000000') as varCHAR(2)) + ' PM'
   end

Wiele funkcji, ale to da ci to ,czego potrzebujesz (testowane na SQL Server 2008)

Edit: poniższe działanie działa nie tylko dla typu time, ale również dla typu datetime.

SELECT SUBSTRING(CONVERT(varchar(20),StartTime,22), 10, 11) AS Start, SUBSTRING(CONVERT(varchar(20),EndTime,22), 10, 11) AS End FROM [TableA];

This returns like 11:30 am

select CONVERT(VARCHAR(5), FromTime, 108) + ' ' + RIGHT(CONVERT(VARCHAR(30), FromTime, 9),2)
from tablename

Spróbuj tego:

select CONVERT(VARCHAR(5), ' 4:07PM', 108) + ' ' + RIGHT(CONVERT(VARCHAR(30), ' 4:07PM', 9),2) as ConvertedTime

> SELECT CONVERT(VARCHAR(30), GETDATE(), 100) as date_n_time
> SELECT CONVERT(VARCHAR(20),convert(time,GETDATE()),100) as req_time
> select convert(varchar(20),GETDATE(),103)+' '+convert(varchar(20),convert(time,getdate()),100)

> Result (1):- Jun  9 2018 11:36AM
> result(2):-  11:35AM
> Result (3):-  06/10/2018 11:22AM

Spróbuj tego:

select CONVERT(varchar(15),CAST('2014-05-28 16:07:54.647' AS TIME),100) as CreatedTime

    select right(convert(varchar(20),getdate(),100),7)
