Mixing
min and max by different conditions in one select
I have a list of offers and requests of goods in 1 table, and i need to find the max priced requests and min priced offers grouped by goods
There is not a big problem to get all requests with max price and all offers with min price, but i need to get offers min price for each request.
My table looks like
ItemName | Type | ItemPrice
-----------------------
item1 | offer | 100
item1 | offer | 80
item1 | request | 120
item2 | offer | 50
item2 | request | 30
item2 | request | 60
And as result i need
ItemName | OfferMinPrice | RequestMaxPrice
-----------------------
item1 | 80 | 120
item2 | 50 | 60

You can just use conditional aggregation:
select itemname,
min(case when type = 'offer' then itemprice end) as min_offerprice,
max(case when type = 'request' then itemprice end) as max_requestprice,
from t
group by itemname;
