declare @min int,@max int,@datarow varchar(2000),@id int
create table #table ( id int, datarow varchar(2000))

set @id=  ''
set @datarow=''
insert into #table(id,datarow)
select 1,'hetejajla'
union all
select 4,'hetejajla'

Select * from #table

Select @min=MIN(id) ,@max =MAX(id) from #table
--- Select @min, @max
while (@min<=@max)
begin

Select @id=id,@datarow=datarow from #table where id =@min
Select @id as id ,@datarow as datarow
set @min=@min+1

--select 
end 

you can see that in my table #table has only two records with ids 1 and 4.
When I run above code which gives me result .

id	datarow
1	hetejajla

id	datarow
1	hetejajla

id	datarow
1	hetejajla


id	datarow
4	hetejajla

because of this 2  records converted on 4 records ...This loop shold only display two entries


id	datarow
1	hetejajla

id	datarow
4	hetejajla


Why this is showing extra records...Pleas suggest me on this tried every possible stuff but can't get rid of the this behaviour.

Hi All

I am finding very strange behaviour inside while ...I have big stored procedure which do the calculation on business requirement . In my sp aim using while loop and its resulting duplicates.. I can't paste that proc here because it doing number of things that i will not be able to explain.. but i created same scenario to explain that issue.

declare @min int,@max int,@datarow varchar(2000),@id int
create table #table ( id int, datarow varchar(2000))

set @id=  ''
set @datarow=''
insert into #table(id,datarow)
select 1,'hetejajla'
union all
select 4,'hetejajla'

Select * from #table

Select @min=MIN(id) ,@max =MAX(id) from #table
--- Select @min, @max
while (@min<=@max)
begin
if exists(select * from #table where id = @min)
begin
Select @id=id,@datarow=datarow from #table where id =@min
Select @id as id ,@datarow as datarow
end
set @min=@min+1

--select 
end
