Sql Query to get an item that contains multiple ids from another table

I have three tables. Container, Inventory and SKU

Container table

ContainerId
C1
C2
C3

Inventory Table

InventoryId	Sku	Container
I1	S1	C1
I2	S1	C2
I3	S2	C1

SKU Table

SkuId
S1
S2
S3

I need to create a sql query that will return the container(s) that contains all of the given SKU ids. So if I want the containers that have SKU S1, my results should be C1 and C2 but if I want to get the containers that have SKU ids S1 and S2 my only result should be C1. C2 should not be a result because it does not have S2.

So far the query I have tried is

SELECT distinct containerId FROM Container c 
   JOIN Inventory i ON i.Container = c.ContainerId
   JOIN SKU s ON s.SkuId = i.Sku
   WHERE s.SkuId IN (S1, S2)

But the WHERE IN statement is a shorthanded OR so it will return C2 as a result too because it contains S1.

I know there is no way to shorthand an AND condition but is there a similar way or a possible way to do this?

Answer

Instead of distinct, you use group by and use count to verify that all required skus were present:

SELECT c.ContainerId
FROM Container c 
JOIN Inventory i ON i.Container = c.ContainerId
JOIN SKU s ON s.SkuId = i.Sku AND s.SkuId in (S1, S2)
GROUP BY c.ContainerId
HAVING COUNT(DISTINCT s.SkuId)=2

But, as commented by others, there’s no need to use any table but Inventory:

SELECT i.Container
FROM Inventory i
WHERE i.Sku in (S1, S2)
GROUP BY i.Container
HAVING COUNT(DISTINCT i.Sku)=2
