Showing dates by day wise, and having default date based on condition - sql

Question

am attaching a query to bring dates to a field,
if system time is before 01:00 pm then it should bring today date+1 else if system date is after or equal 01:00 pm it should bring today date +2
further , user can see the query result that will show him a date range along side with day names , and select one of them manually if the above cases wasn't what the user is looking for .
queries are avilable and working fine but separately,
one query bring date range , and one query set the date based on a condition , i need to make them one query , that bring the date ranges and set default date to be based on the conditions;
here are the queries :
Note : Q No 2 , I tried to make both queries as one query but its not bring the correct result , it keep bring today date +1 no matter what system time is.
1)
If DATEPART(Hour,Getdate())<12
SELECT GetDate()+1
If DATEPART(Hour,Getdate())>=12
SELECT GetDate()+2
2)
If DATEPART(Hour,Getdate())<12
DECLARE #Date1 DATE, #Date2 DATE
SET #Date1 = GetDate()+0
SET #Date2 = GetDate()+365
SELECT DATEADD(DAY,number+1,#Date1) [Date], DateName(Weekday,DATEADD(DAY,number+1,#Date1)) as dayname
FROM master..spt_values
WHERE type = 'P'
AND DATEADD(DAY,number+1,#Date1) < #Date2
If DATEPART(Hour,Getdate())>=12
DECLARE #Date3 DATE, #Date4 DATE
SET #Date3 = GetDate()+2
SET #Date4 = GetDate()+365
SELECT DATEADD(DAY,number+1,#Date3) [Date], DateName(Weekday,DATEADD(DAY,number+1,#Date3)) as dayname
FROM master..spt_values
WHERE type = 'P'
AND DATEADD(DAY,number+1,#Date3) < #Date4

I've used a CTE to calculate the start date. The CTE uses a CASE statement to tell if it is being run before or after 12.
WITH Base AS
(
/* Returns the start date based on the current time.
* Before midday the start date is today.
* After midday it is the day after tomorrow.
*/
SELECT
CASE
-- Use current time to calculate start date.
WHEN DATEPART(HOUR, GETDATE()) < 12 THEN DATEADD(DAY, 0, GETDATE())
ELSE DATEADD(DAY, 2, GETDATE())
END AS StartDate
)
SELECT
DATEADD(DAY, sv.Number + 1, b.StartDate) AS [Date],
DATENAME(WEEKDAY, DATEADD(DAY, sv.Number + 1, b.StartDate)) AS [DateName]
FROM
master..spt_values AS sv
CROSS JOIN Base AS b
WHERE
sv.[type] = 'P'
AND DATEADD(DAY, Number + 1, b.StartDate) < DATEADD(YEAR, 1, b.StartDate)
;
