Question

I have a table called Timezone and the data looks like:

Call_ID        Start_Time
93856          2011-08-04 09:59:47.000
58796          2011-08-05 14:54:37.000
25489          2011-08-09 15:32:13.000

I want the output as :

Call_ID        Start_Time                    Interval
93856          2011-08-04 09:59:47.000       0930
58796          2011-08-05 14:54:37.000       1430
25489          2011-08-09 15:32:13.000       1530

I did something like this:

Select  Call_ID , Start_Time,
CASE WHEN DATEPART(minute,Start_Time)>30 THEN 
RIGHT('0' + CAST(DATEPART(HOUR,Start_Time) AS VARCHAR),2) + '30'          
ELSE 
RIGHT('0' + CAST(DATEPART(HOUR,Start_Time) AS VARCHAR),2) + '00'        
END
From Timezone
Group By Call_ID , Start_Time,
CASE WHEN DATEPART(minute,Start_Time)>30 THEN 
RIGHT('0' + CAST(DATEPART(HOUR,Start_Time) AS VARCHAR),2) + '30'          
ELSE 
RIGHT('0' + CAST(DATEPART(HOUR,Start_Time) AS VARCHAR),2) + '00'        
END

Is there a better way of doing it?

Answer 1

select Call_ID,
       Start_Time,
       right(100+datepart(hour, Start_Time), 2)+
       right(100+30*(datepart(minute, Start_Time)/30), 2) as Interval
from TimeZone
