In this task you are expected to fix an SQL query based on feedback. You will be given an SQL statement and an English description with what is wrong about that SQL statement. You must correct the SQL statement based off of the feedback. An SQL query works by selecting data from a table where certain conditions apply. A table contains columns where every row in that table must have a value for each column. Every table has a primary key that uniquely identifies each row, usually an id. To choose which columns are returned you specify that after the "SELECT" statement. Next, you use a "FROM" statement to specify what tables you want to select the data from. When you specify a table you can rename it with the "AS" statement. You can reference that table by whatever name follows the "AS" statement. If you want to select data from multiple tables you need to use the "JOIN" statement. This will join the tables together by pairing a row in one table with every row in the other table (Cartesian Product). To limit the number of rows returned you should use the "ON" statement. This will only return rows where the condition specified after the statement is true, this is usually an equals operator with primary keys. You can also use the "WHERE" statement to specify that only rows with column values statisfying a certain condition, should be returned. The "GROUP BY" statement will group rows together that have equal column values for whatever columns follows the statement. The "HAVING" statement will return groups that statisfy whatever condition follows the statement. Any column(s) being returned from grouped rows must either be an aggregate function, (AVG, MAX, COUNT, SUM, ...) of a column, or the column(s) that the data was grouped by. To sort the returned data you can use the "ORDER BY" command which will order the data by whatever aggregate function or column follows the statement. The "DESC" statement will sort in descending order and the "ASC" statement will sort in ascending order. Finally, you can use the "LIMIT" statement to return a certain number of rows. When "*" is used in an SQL statement every column is returned. For example, SELECT * FROM table WHERE attribute = 1, will select every column from rows with the attribute column equal to 1. 

[EX Q]: SQL: SELECT T2.Location , T2.Representative_Name FROM company AS T1 JOIN gas_station AS T2 JOIN station_company AS T3 ON T1.Company_ID = T3.Company_ID AND T3.Station_ID = T2.Station_ID ORDER BY T1.Market_Value Desc LIMIT 3
Feedback: Replace market value by assets billion .
[EX A]: SELECT T3.location ,  T3.Representative_Name FROM station_company AS T1 JOIN company AS T2 ON T1.company_id  =  T2.company_id JOIN gas_station AS T3 ON T1.station_id  =  T3.station_id ORDER BY T2.Assets_billion DESC LIMIT 3

[EX Q]: SQL: SELECT T1.semester FROM section AS T1 JOIN takes AS T2 ON T1.year = T2.year WHERE T2.year ! = 2010
Feedback: Substitute semester with course id , Ensure it equals semester fall and year 2009 , not equals semester Spring .
[EX A]: SELECT course_id FROM SECTION WHERE semester  =  'Fall' AND YEAR  =  2009 EXCEPT SELECT course_id FROM SECTION WHERE semester  =  'Spring' AND YEAR  =  2010

[EX Q]: SQL: SELECT name FROM station WHERE long < -121.90178200000001 AND city = "San Jose" UNION SELECT name FROM station WHERE long > 10 AND city = "San Jose"
Feedback: Need to find bikes available instead of longitude and city does not equals San Jose .
[EX A]:
SELECT T1.name FROM station AS T1 JOIN status AS T2 ON T1.id  =  T2.station_id GROUP BY T2.station_id HAVING avg(bikes_available)  >  10 EXCEPT SELECT name FROM station WHERE city  =  "San Jose"
