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 Input:
SQL: SELECT Avg ( Age ) , Max ( Age ) FROM artist WHERE Country = "United States"
Feedback: Need to replace maximum with minimum .

Ex Output:
SELECT avg(age) ,  min(age) FROM artist WHERE country  =  'United States'


Ex Input:
SQL: SELECT country , Count ( * ) FROM airports GROUP BY country
Feedback: find name , country from airlines table , ensure each rows correspond airline id of routes table .

Ex Output:
SELECT T1.country ,  T1.name ,  count(*) FROM airlines AS T1 JOIN routes AS T2 ON T1.alid  =  T2.alid GROUP BY T1.country ,  T1.name


Ex Input:
SQL: SELECT Count ( * ) FROM Tourist_Attractions AS T1 WHERE T1.Tourist_Attraction_ID NOT IN ( SELECT T2.Tourist_Attraction_ID FROM Visits AS T2 )
Feedback: In step 1 and 2 exchange tourist attraction id with tourist id , now in step 2 need to replace tourist attractions with visitors .

Ex Output:

SELECT count(*) FROM Visitors WHERE Tourist_ID NOT IN ( SELECT Tourist_ID FROM Visits )
