something like: SELECT CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(GETDATE())-1),GETDATE()),101) AS FirstDay

(the first day is always the first :)  )

so add (1 - today's day number) to today's date.

select dateadd(day, 1-day(getdate()), getdate()) as date

Open in new window


And for a date, cast it to one:

select cast(dateadd(day, 1-day(getdate()), getdate()) as date)

Open in new window

I have tried all of your suggestions and I error on the dateadd function.  I have tried this:
(add_months(getdate(),-1)) and it returns 10/31/2013.

what is your database engine? all these queries should work on Microsoft SQL Server.

Then you're not running SQL Server.

If (add_months(getdate(),-1)) gives the end of last month then what about

add_days(    getdate(),    1 - day(getdate()    )
