Split Row and Paste to Different Tables Based on Column - sql

Question

I have a table like this. Table is populated each time an order is complete. One order can have one or many compartments.
+---------+-------+-------------+------+
| OrderID | Plant | Compartment | Qty |
+---------+-------+-------------+------+
| 91 | 12 | 1 | 2000 |
| 91 | 12 | 2 | 2000 |
| 91 | 12 | 3 | 2000 |
| 90 | 12 | 1 | 3000 |
| 89 | 12 | 1 | 5000 |
+---------+-------+-------------+------+
Please help write an SQL script that takes the above and splits it into two new tables like so:
Table 1
+---------+-------+
| OrderID | Plant |
+---------+-------+
| 91 | 12 |
| 90 | 12 |
| 89 | 12 |
+---------+-------+
Table 2
+---------+-------------+------+
| OrderID | Compartment | Qty |
+---------+-------------+------+
| 91 | 1 | 2000 |
| 91 | 2 | 2000 |
| 91 | 3 | 2000 |
| 90 | 1 | 3000 |
| 89 | 1 | 5000 |
+---------+-------------+------+
I've tried using the DISTINCT command as suggested;
SELECT * FROM table
WHERE [OrderID] = (SELECT DISTINCT OrderID from table where (COMPARTMENT = '1'))
Which returns the error;
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
If the script can keep track of already processed rows so as to avoid duplication each time it runs, that would be the icing on the cake.

This is how I'd do:
-- just for debugging, your table is my #table variable table
set nocount on
declare #table table (OrderId int, Plant int, Compartment int, Qty int)
insert into #table values (89, 12, 1, 5000)
insert into #table values (90, 12, 1, 3000)
insert into #table values (91, 12, 3, 2000)
insert into #table values (91, 12, 2, 2000)
insert into #table values (91, 12, 1, 2000)
insert into #table values (91, 12, 2, 3000)
set nocount off
--select * from #table
-- now here it comes selections:
if (exists (select *
from INFORMATION_SCHEMA.TABLES
where TABLE_SCHEMA = 'dbo' -- or your schema
and TABLE_NAME = 'THeader' -- or your header's table))
insert into THeader
select distinct t1.OrderId, t1.Plant
from #table t1
left join THeader t2 on t1.OrderId = t2.OrderId and t1.Plant = t2.Plant
where t2.OrderId is null
else
select distinct t1.OrderId, t1.Plant
into THeader
from #table t1
left join THeader t2 on t1.OrderId = t2.OrderId and t1.Plant = t2.Plant
where t2.OrderId is null
if (exists (select *
from INFORMATION_SCHEMA.TABLES
where TABLE_SCHEMA = 'dbo' -- or your schema
and TABLE_NAME = 'TChilds' -- or your childs's table))
insert into TChilds
select distinct t1.OrderId, t1.Compartment, t1.Qty
from #table t1
left join TChilds t2 on t1.OrderId = t2.OrderId and t1.Compartment = t2.Compartment and t1.Qty = t2.Qty
where t2.OrderId is null
else
select distinct t1.OrderId, t1.Compartment, t1.Qty
into TChilds
from #table t1
left join TChilds t2 on t1.OrderId = t2.OrderId and t1.Compartment = t2.Compartment and t1.Qty = t2.Qty
where t2.OrderId is null
-- just for debugging
select * from THeader
select * from TChilds
Edit: Even so, I see your master table as a child table, from where you must create Header's table. It's enough. I mean your Table can be my TChilds table, and key can be OrderId + Plant. (I don't know what means plant in this table)
