Tijden veranderen
max, min & highest in één query
1) de grootste overwinning
2) het grootste verlies
3) de wedstrijd met de meeste doelpunten
Met dit script krijg ik alle wedstrijdn maar hoe filter ik de 1) 2) & 3) records eruit?

met deze code bepaal ik de het doelsaldo en highests core

Verschil_won is het grootst bij de grootste overwinning, verschil_lose is het grootst bij het grootste verlies. Je kunt het beste deze drie dingen gebruiken in de WHERE-clauses om de juiste wedstrijden (en dus de juiste uitslagen) te krijgen.
EDIT: Ik gok dat je JOINs moet gaan gebruiken...

Maar ik zit er nu mee dat ik twijfel hoe en wara ik de juiste records kan selecteren.
a) in de Query
b) in PHP script
