TASK DEFINITION: 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. 
PROBLEM: SQL: SELECT Name FROM artwork WHERE Type = "Program Talent Show"
Feedback: Find festival detail 's festival name whose corresponding festival id is present in nomination table along with artwork id for type equals Program Talent Show and result equals Nominated .

SOLUTION: SELECT T3.Festival_Name FROM nomination AS T1 JOIN artwork AS T2 ON T1.Artwork_ID  =  T2.Artwork_ID JOIN festival_detail AS T3 ON T1.Festival_ID  =  T3.Festival_ID WHERE T2.Type  =  "Program Talent Show"

PROBLEM: SQL: SELECT train_number , time FROM train WHERE destination = "Chennai"
Feedback: Check that destination should be Guruvayur and origin should be Chennai .

SOLUTION: SELECT train_number ,  TIME FROM train WHERE origin  =  'Chennai' AND destination  =  'Guruvayur'

PROBLEM: SQL: SELECT T1.name , T2.network_name FROM train AS T1 JOIN station AS T2 JOIN route AS T3 ON T1.id = T3.train_id AND T3.station_id = T2.id WHERE T2.network_name = "Chiltern"
Feedback: Change network name with time and Use local authority equals Chiltern instead of network name equals Chiltern .

SOLUTION:
SELECT t3.name ,  t3.time FROM station AS t1 JOIN route AS t2 ON t1.id  =  t2.station_id JOIN train AS t3 ON t2.train_id  =  t3.id WHERE t1.local_authority  =  "Chiltern"
