WHERE (matches.winning_country = winning_country.country_id)

AND (matches.losing_country = losing_country.country_id)

AND (totalpoints>50)

 

When I run this query, I get an error saying column totalpoints does not exist. Why is that?

Good question,

 

try:

 

SELECT day, month, year,

winning_country.country_name winning_country,

losing_country.country_name losing_country,

matches.winning_score, matches.losing_score, location, crowd, worldcup, ((matches.winning_score + matches.losing_score) as totalpoints)

FROM matches,

countries winning_country,

countries losing_country

WHERE (matches.winning_country = winning_country.country_id)

AND (matches.losing_country = losing_country.country_id)

AND (totalpoints>50) 

 

If that doesn\'t work, then try putting

 

(matches.winning_score + matches.losing_score) > 50

 

in the WHERE clause instead...
