"FROM keyword not found where expected" (Oracle SQL) - sql

Question

So I have the following query which gives me the error in the title. I have no idea why it's giving me the error.
CREATE OR REPLACE VIEW AUSTRALIANMEDALTALLY
AS
SELECT concat(SG_HOSTCITY, SG_YEAR) as 'ioc_game',
SUM(p.part_gold) as 'gold_medals',
SUM(p.part_silver) as 'silver_medals',
SUM(p.part_bronze) as 'bronze_medals'
FROM GAMES.SUMMERGAMES, GAMES.PARTICIPATION
WHERE COUNTRY_ISOCODE = AUS
GROUP BY COUNTRY_ISOCODE;
Any idea why I'm getting the error?

Answer 1

As well as AUS needing to to be quoted as 'AUS', your aliases either need to be double-quoted:
SELECT concat(SG_HOSTCITY, SG_YEAR) as "ioc_game",
which makes them case-sensitive, or not quoted at all:
SELECT concat(SG_HOSTCITY, SG_YEAR) as ioc_game,
And the same for the other aliases.
You also refer to a p as a table alias but you don't define that - presumably that's for participants - and you aren't defining how the tables are related, so you're doing a cross-join. Seems like you probably have the country in both tables, too, so you need to prefix the references with the table alias.
And you're grouping by a column that isn't in the select-list, which will cause its own error; you need to group by any columns you aren't aggregating.
CREATE OR REPLACE VIEW AUSTRALIANMEDALTALLY
AS
SELECT concat(s.SG_HOSTCITY, s.SG_YEAR) as ioc_game,
SUM(p.part_gold) as gold_medals,
SUM(p.part_silver) as silver_medals,
SUM(p.part_bronze) as bronze_medals
FROM GAMES.SUMMERGAMES s
JOIN GAMES.PARTICIPATION p
ON p.gamesno = s.gamesno
WHERE p.COUNTRY_ISOCODE = 'AUS'
GROUP BY s.SG_HOSTCITY, s.SG_YEAR;

Answer 2

WHERE COUNTRY_ISOCODE = AUS
change to
WHERE COUNTRY_ISOCODE = 'AUS'
