Hello everyone, How can I prevent group by clause from reducing the number of rows without affecting accuracy of what aggregate functions provide?
Scenario: My club has-many coaches. Each coach trains a team of players. Of course, a player has-many matches and a match has-many players. Given the schema: https://pastebin.com/raw/C77mXsHJ and sample data: https://pastebin.com/raw/GhsYktRS I want a result like: https://pastebin.com/raw/stikDvYS NOTE: for a match X, profit/match is `sum(salary of all players playing in X) - X.bets` To get the result, here's what I came up with: https://pastebin.com/ckgicBWS If I un-comment those lines, I get the profit column but rows are reduced, how can I prevent that? Thanks, Rocky. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
