Hi,
I have a calculated field which subtracts two dates (See SQL statement below). Right now it returns a date such as 1901-02-15 00:00:00.000. I want it to simply return an interger such as 44. Can someone help me format this correctly?

dbo.vReadmit30Days2.AdmitDate2 - dbo.vReadmit30Days2.DischargeDate AS ReadmitDays

Thanks,
Chuck

[code]
DECLARE @d1 datetime; SET @d1 = '1/1/2010'
DECLARE @d2 datetime; SET @d2 = '2/14/2010'
SELECT DATEDIFF(dd,@d1,@d2)

[/code]

Brett, Thanks for your help. I am new to this forum and to SQL Server (this is my second post). I did research the question before hand but could not come up with an answer. Was there something lacking in my question? I could have posted the entire SQL Statement but it was pretty massive. Chuck
