# Tune this complex WHERE clause

## How do we tune the following where clause?

How do we tune the following where clause:

``` (  shipper_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
OR consignee_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
OR freight_payer_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
OR beneficial_owner_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
OR care_of_party_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
OR notify_party_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
OR property_owner_id
IN (select organization_id from orgrelation
where act_as_to_org_id = 900009
union
select 900009 from dual)
)```

Let's look at this portion of the IN subquery --

```select organization_id from orgrelation
where act_as_to_org_id = 900009  ```

Notice that this is exactly the same query in every IN clause. Now, if this query returns exactly one row, then you can simplify your big complex WHERE condition like this --

``` (  (select organization_id from orgrelation
where act_as_to_org_id = 900009 )
IN ( shipper_id
, consignee_id
, freight_payer_id
, beneficial_owner_id
, care_of_party_id
, notify_party_id
, property_owner_id  )
OR 900009
IN ( shipper_id
, consignee_id
, freight_payer_id
, beneficial_owner_id
, care_of_party_id
, notify_party_id
, property_owner_id  )
)```

This isn't actually "tuning" but it does simplify things a little.
