having an and condition on multiple rows - sql server - sql

Question

i have the following query where i'm trying to select one value based on a condition
select distinct tblItemTypePropValue.ItemType_Fkey, tblItemPrice.price, dbo.fnGetDiscountItemType(tblItemTypePropValue.ItemType_Fkey) as finalPrice
from tblItemTypePropValue
inner join tblItemPrice
on tblItemTypePropValue.ItemType_Fkey = tblItemPrice.itemType_fkey
where Value_Fkey in (2097,2131)
and tblitemtypepropvalue.ItemType_Fkey in (select id from tblItemType where Item_Fkey = 12241)
the problem is i n the where in value_fkey in (2097,2131)
is there a way to write an and condition on multiple rows where value_fkey = 2097 and = 2131.
and also, can it be done without a join since my parameters inside the in can vary in count.
sample result
itemtype_fkey price finalPrice
6191 100 93
so the query will only return the ItemType_Fkey that has both Value_Fkeys specified in the query
Value
thanks,

Answer 1

You can do two INNER JOINs and check for the existence of the 2097 and 2131 keys on them.
Being INNER JOINS, only the Prices having both of those keys will be returned.
select distinct P.ItemType_Fkey, P.price,
dbo.fnGetDiscountItemType(P.ItemType_Fkey) as finalPrice
from tblItemType T
inner join tblItemPrice P on P.ItemType_Fkey = T.id
inner join tblItemTypePropValue V1 on V1.ItemType_Fkey = P.ItemType_Fkey and V1.Value_Fkey = 2097
inner join tblItemTypePropValue V2 on V2.ItemType_Fkey = P.ItemType_Fkey and V2.Value_Fkey = 2104
where T.Item_Fkey = 12241

Answer 2

select distinct tblItemTypePropValue.Value_Fkey,tblItemTypePropValue.ItemType_Fkey, tblItemPrice.price, dbo.fnGetDiscountItemType(tblItemTypePropValue.ItemType_Fkey) as finalPrice
from tblItemTypePropValue
inner join tblItemPrice
on tblItemTypePropValue.ItemType_Fkey = tblItemPrice.itemType_fkey
where ((Value_Fkey = 2097) or (Value_Fkey = 2131))
and tblitemtypepropvalue.ItemType_Fkey in (select id from tblItemType where Item_Fkey = 12241)

Answer 3

You probably want those items where rows for both Value_Fkey exist like this
SELECT
v.ItemType_Fkey,
max(p.price), -- max/min/avg?
dbo.fnGetDiscountItemType(v.ItemType_Fkey) AS finalPrice
FROM tblItemTypePropValue AS v
INNER JOIN tblItemPrice AS p
ON v.ItemType_Fkey = p.itemType_fkey
WHERE Value_Fkey IN (2097,2131) --- list of values
AND v.ItemType_Fkey
IN ( SELECT id
FROM tblItemType
WHERE Item_Fkey = 12241
)
GROUP BY v.ItemType_Fkey
HAVING COUNT(DISTINCT Value_Fkey) = 2 -- number of values in list
