My table has a parent/child relationship, along the lines of parent.id,id. There is also a column that contains a quantity, and another ID representing a grand-parent, like so:
id parent.id qty Org 1 1 1 100 2 1 0 100 3 1 4 100 4 4 1 101 5 4 2 101 6 6 1 102 7 6 0 102 8 6 1 102
What this is supposed to show is ID 1 is the parent, and ID 2 and 3 are children which belongs to ID 1, and ID 1, 2, and 3 all belong to the grandparent 100.
I would like to know if any child or parent has QTY = 0, what are all the other id's associated to that parent, and what are all the other parents associated with that grandparent?
For example, I would want to see a report that shows me this:
Org id parent.id qty 100 1 1 1 100 2 1 0 100 3 1 4 102 6 6 1 102 7 6 0 102 8 6 1
Much appreciate any help you can offer to build a MS SQL 2000 (yeah, I know) query to handle this.
Try this
select * from tablename a
where exists (select 1 from tablename x
where x.parent_id = a.parent_id and qty = 0)
Example:
;with cte as
( select 1 id,1 parent_id, 1 qty, 100 org
union all select 2,1,0,100
union all select 3,1,4,100
union all select 4,4,1,101
union all select 5,4,2,101
union all select 6,6,1,102
union all select 7,6,0,102
union all select 8,6,1,102
)
select * from cte a
where exists (select 1 from cte x
where x.parent_id = a.parent_id and qty = 0)
