Question

Trying this to cast time away

   select CONVERT(char(10), [Reg Date1], 103) [Reg Date], Regs
    from (
          select cast(SetupDateTime as DATE) [Reg Date1]
               , COUNT(distinct ID) [Regs]
          from dbo.tbl_User
          where cast(SetupDateTime as DATE) 
                between cast((DATEADD (dd , -7 , GETDATE())) AS DATE) 
                    and cast((DATEADD (dd , -1 , GETDATE())) AS DATE)
          group by cast(SetupDateTime as DATE)
        ) a
    order by a.[Reg Date1]

but I get this error

You are using SQL Server 2005 or earlier. Data type date was introduced in SQL Server 2008. Try to cast to datetime instead.
