I have this error. I am new to SQL and can’t figure what is wrong with my syntax. I changed my INTERSECT statement to inner join realizing SQL does not accept such syntax. However I continue to get an error.
ERROR:

INNER JOIN
(Select h.propertyId as id
From House h, has_weather hw, weather_ye' at line 8
The query is suppose to find the userIDs and the email of user who’s property has ratings equal to 5 and has AvgTemp over 55.
Select has_property.userId
From has_property
Where has_property.propertyId IN
(
(Select hRR.propertyId as id
From hasRatings_Rate hRR
Where hRR.ratingId = 5
) a
INNER JOIN
(Select h.propertyId as id
From House h, has_weather hw, weather_year wy
Where hw.weatherId = wy.weatherId AND hw.homeAddId = h.homeAddId AND wy.AvgTemp > 55
)b
ON (a.id = b.id)
);

Answer
Try this:
Select has_property.userId
From has_property hp
JOIN hasRatings_Rate hRR ON hp.propertyId = hRR.propertyId
JOIN House h ON h.id = hRR.id
JOIN has_weather hw ON hw.homeAddId = h.homeAddId
JOIN weather_year wy ON hw.weatherId = wy.weatherId
WHERE hRR.ratingId = 5
AND wy.avgTemp > 55
No need for any subqueries, just a succession of joins.
