What percentage of games won, games lost and games drawn does Cittadella have as a home team in total?
Percentage of games won = DIVIDE(COUNT(FTR = 'H' where HomeTeam = 'Cittadella'), COUNT(Div where HomeTeam = 'Cittadella')) as percentage; Percentage of games lost = DIVIDE(COUNT(FTR = 'A' where HomeTeam = 'Cittadella')), COUNT(Div where HomeTeam = 'Cittadella') as percentage; percentage of games drawn = DIVIDE(SUM(FTR = 'D'where HomeTeam = 'Cittadella'), COUNT(Div where HomeTeam = 'Cittadella')) as percentage;

SELECT CAST(COUNT(CASE WHEN FTR = 'H' THEN 1 ELSE NULL END) / COUNT(HomeTeam) AS REAL) * 100, CAST(COUNT(CASE WHEN FTR = 'A' THEN 1 ELSE NULL END) AS REAL) / COUNT(HomeTeam), CAST(COUNT(CASE WHEN FTR = 'D' THEN 1 ELSE NULL END) AS REAL) / COUNT(HomeTeam) FROM matchs WHERE HomeTeam = 'Cittadella'
