select @Pipno

but in select @Pipno prints only one row (ie, max of V_3) i want to store all five or more rows in this @Pipno variable please reply me

Answer 1

You can use a table variable.

declare @Pipno table(V_3 varchar(500))

insert into @Pipno
select V_3 
from REPORTDATE

select V_3
from @Pipno

Or if you want the result as one string.

declare @Pipno varchar(500)
set @Pipno = ''

select @Pipno = @Pipno + V_3 + ' '
from REPORTDATE

select @Pipno
