Hi Guys and Girls,
I have the following:
SELECT CAST(CONVERT(VARCHAR(8), GETDATE(), 112) AS INT)
SELECT DATEADD(m, DATEDIFF(m, 0, GETDATE()), 0)
The first sets getdate() to an int.
The second set the date to the first of the month.
Does anyone have an idea how I can combine the two to set the date to the beginning of the month but still as an integer?
Kind regards
Fred

SELECT YEAR(GETDATE()) * 10000 + MONTH(GETDATE()) * 100 + 1;

Thanks Koen.

For consistency, I'd stick with just explicitly CASTing the second value to an int:

SELECT CAST(DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0) AS int)

I agree with you, but you missed the intermediate convert.

SELECT CAST(CONVERT( char(8), DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0), 112) AS int)

Hmm, but no intermediate conversion is needed. Dates already are ints, and ints are de facto dates.
