…predicate
```
SELECT *
FROM
(SELECT cs_order_number,
cs_warehouse_sk
FROM catalog_sales
WHERE cs_order_number = 125005
AND cs_warehouse_sk = 4) cs1
LEFT SEMI JOIN
(SELECT cs_order_number,
cs_warehouse_sk
FROM catalog_sales
WHERE cs_order_number = 125005) cs2
ON cs1.cs_order_number = cs2.cs_order_number
AND cs1.cs_warehouse_sk <> cs2.cs_warehouse_sk;
```
The above query has an equal predicate and a not equal predicate.
If there exists not equal preidcate, the build table should be remained
as it is. So the deduplication should be removed.
