Stored Procedure using Date/Time Comparison

Question

I’m running SQL Server 2012. I need to write a procedure that will send out emails based on a date/time comparison.
In my table, ‘tickets’, I have a smalldatetime column ‘ticket_date’ and another column ‘responded’ which is a bit field. I need to check the current date to see if 24 hours has passed from the ticket_date. If 24 hours has passed and responded is 0, then
I need to email a manager ( I already have the code for  emailing with SMTP).
The next step is to see if 48 hours has passed from the ticket_date and if responded is 0.
 If this is true, then I need to email someone else.
I don’t want to include weekends in my time comparison. My procedure will only run Mon – Fri. 
Thanks in advance!

Check the below sample and hope this will help you:
DECLARE @Tickets TABLE (TicketID INT, TicketDate SMALLDATETIME, Responded BIT)
INSERT INTO @Tickets
SELECT 1, '01/10/2015 10:00AM', 0 UNION ALL
SELECT 2, '01/13/2015 12:00PM', 1 UNION ALL
SELECT 3, '01/12/2015 05:30PM', 0 UNION ALL
SELECT 4, '01/09/2015 08:00AM', 1
SELECT *, '24 Hour' AS TicketCase
FROM
@Tickets
WHERE
Responded = 0
AND DATEDIFF(HOUR, TicketDate, CURRENT_TIMESTAMP) <= (CASE DATEPART(WEEKDAY, TicketDate) WHEN 7 THEN 48 WHEN 1 THEN 24 ELSE 0 END) + 24
UNION ALL
SELECT *, '48 Hour' AS TicketCase
FROM
@Tickets
WHERE
Responded = 0
AND DATEDIFF(HOUR, TicketDate, CURRENT_TIMESTAMP) >= 24
AND DATEDIFF(HOUR, TicketDate, CURRENT_TIMESTAMP) <= (CASE DATEPART(WEEKDAY, TicketDate) WHEN 7 THEN 48 WHEN 1 THEN 24 ELSE 0 END) + 48
Output
TicketID | TicketDate | Responded | TicketCase
3 | 2015-01-12 17:30:00 | 0 | 24 Hour
1 | 2015-01-10 10:00:00 | 0 | 48 Hour
You can make the separate SQL statements and email to proper people based on 24 hour or 48 hour case.
