Question

How to increment a value of local variable in the loop inside a stored procedure

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; 
Select @CNT=(Select Count(*) from (select Distinct(setno)from onlin) AS A)
select @test=@NoOfQuestion/@CNT
while @x <= @CNT do 
    while @y <= @test
        select  * from onlin where setno = @x
        set @y = @y +1
    set @x =@x + 1 
END

the values like @x and @y is not incrementing and I am stuck in an infinite loop.

Answer 1

you have to enclose the while-body in a begin-end block.

while @x <= @CNT do begin
  while @y <= @test begin
    select  * from onlin where setno = @x
    set @y = @y + 1
  end
set @x =@x + 1
end

I do not understand what you are trying to achive (besides the fact that you want to increase some variables)
