Insert or update value on table where values can be repeated multiple times
Previously I was using the following table:
CREATE TABLE Users(user BIGINT PRIMARY KEY,
item_count INT);
which allowed me to do a simple upsert:
INSERT INTO Users(user, item_count)
VALUES($1, $2)
ON CONFLICT(user) DO
UPDATE SET item_cout = user.item_count + 1;
However I want to switch my table to have more columns so each user have a different item_count per server so I did:
CREATE TABLE Users(id SERIAL PRIMARY KEY,
server BIGINT NOT NULL,
user BIGINT NOT NULL,
item_count INT);
However I'm not allowed to do an ON CONFLICT anymore in this case because neither server nor user are unique, and they can be repeated throughout the table for example:
id server user item_count
1 1 1 95
2 2 1 345
3 1 2 594
4 3 1 0
Is there any way to do an upsert with the second table instead of separating the query into two statements? (one for insert if not exists and one for updating)
