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 T1.Address FROM Locations AS T1 JOIN Tourist_Attractions AS T2 ON T1.Location_ID = T2.Location_ID JOIN Shops AS T3 ON T2.Tourist_Attraction_ID = T3.Shop_ID WHERE T3.Shop_Details = "Vincent"
Feedback: Exchange locations with visits , shops with visitors , address with name , shop details with tourist details .

Ex Output:
SELECT T1.Name FROM Tourist_Attractions AS T1 JOIN VISITS AS T2 ON T1.Tourist_Attraction_ID  =  T2.Tourist_Attraction_ID JOIN VISITORS AS T3 ON T2.Tourist_ID  =  T3.Tourist_ID WHERE T3.Tourist_Details  =  "Vincent"


Ex Input:
SQL: SELECT T1.Name , T2.born_state , T1.Num_Employees FROM department AS T1 JOIN head AS T2 JOIN management AS T3 ON T1.Department_ID = T3.department_ID AND T3.head_ID = T2.head_ID ORDER BY T2.age Asc
Feedback: Replace name with name , num employees with age .

Ex Output:
SELECT name ,  born_state ,  age FROM head ORDER BY age


Ex Input:
SQL: SELECT DISTINCT cust_name FROM customer ORDER BY acc_bal Asc
Feedback: account balance is wrong . It should be replaced with amount and confirm that customer took a loan .

Ex Output:

SELECT T1.cust_name FROM customer AS T1 JOIN loan AS T2 ON T1.cust_id  =  T2.cust_id GROUP BY T1.cust_name ORDER BY sum(T2.amount)
