Question

ALTER PROC [dbo].[Usp_SelectQuestion]
   @NoOfQuestion int
AS
BEGIN
  Declare @CNT int
  Declare @test int
  Declare @x int
  Declare @y int

  set @x = 1;
  set @y = 1; 
  set @CNT=(Select Count(*) from (select Distinct(setno)from onlin) AS A)
  set @test=@NoOfQuestion/@CNT

  while (@x <= @CNT)  
  begin
    select top (@test) * from onlin where setno = @x order by NEWID()
      set @x = @x + 1
  end
END

In this stored procedure I am getting output as single table for every loop so I am getting multiple tables as output but I want all rows in a single table I think through union we can achieve but I do not know how to use.

Answer 1

declare @temptable as table(col1 int, col2 varchar(50),... etc)

  while (@x <= @CNT)  
  begin
     insert into @temptable   'temptable columns need to match columns in the SELECT statement
        select top (@test) * from onlin where setno = @x order by NEWID()

     set @x = @x + 1
  end

  select * from @temptable
