min and max by different conditions in one select












1















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;
