exactly the same :

Like aneeshattingal said (points to him, not me please)

declare @countme int
declare @count1 int
declare @sql nvarchar(500)

SELECT @sql='select @countme=count(*), @count1=count(*) from '+ @tempval

EXEC sp_executeSQL @SQl, N'@countme int Output @count1 int output',@countme output, @count1 output

SELECT @countme, @count1

I suggest you also have a look at the documentation regarding sp_executsql to understand what's going on here... .
