Question

I am having a problem adjusting this part of my SQL statement:

HAVING dbo.BOOKINGS.BOOKED = CONVERT(int, CONVERT(datetime, 
                                                  FLOOR(CONVERT(float, GETDATE()))) + 2)

Normally, the page that uses this statement just lists the amount of sales for today, I want to switch the GETDATE() to a date that I declare. I tried all different formats and none have worked

Answer 1

Use the DATEADD/DATEDIFF method of setting the time portion to midnight of the current date – it’s the fastest means, and casting to FLOAT can be unreliable:

HAVING BOOKINGS.dbo.BOOKED = CONVERT(INT, DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0))+2

Then, you can set your own date easily if you use a variable (@var in this example, within a stored procedure or function):

DECLARE @var DATETIME

SELECT ...
HAVING BOOKINGS.dbo.BOOKED = CONVERT(INT, DATEADD(dd, DATEDIFF(dd, 0, @var), 0))+2

This assumes @var is a DATETIME data type. Otherwise, you’ll need to use a date format SQL Server will implicitly convert to a DATETIME — or use CAST/CONVERT to explicitly convert the value.
