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. 

SQL: SELECT T1.title FROM albums AS T1 JOIN tracks AS T2 ON T1.id = T2.album_id WHERE T2.name LIKE "Led"
Feedback: Need to make sure name is from artist table .
SELECT T2.title FROM artists AS T1 JOIN albums AS T2 ON T1.id  =  T2.artist_id WHERE T1.name LIKE '%Led%'

SQL: SELECT T2.Name , T1.Address FROM Locations AS T1 JOIN Tourist_Attractions AS T2 ON T1.Location_ID = T2.Location_ID GROUP BY T2.Location_ID HAVING Count ( * ) > = 2
Feedback: Change locations table with visits table , Tourist Attractions's location id with Visits's tourist attraction id and address with tourist attraction id .
SELECT T1.Name ,  T2.Tourist_Attraction_ID FROM Tourist_Attractions AS T1 JOIN VISITS AS T2 ON T1.Tourist_Attraction_ID  =  T2.Tourist_Attraction_ID GROUP BY T2.Tourist_Attraction_ID HAVING count(*)  >=  2

SQL: SELECT T2.student_id FROM Student_Course_Registrations AS T1 JOIN Student_Course_Attendance AS T2 ON T1.course_id = T2.course_id ORDER BY T1.registration_date Desc LIMIT 1
Feedback: Make sure course id equals 301 and in step 2 , there should be student course registrations instead of student course attendance .

SELECT student_id FROM student_course_attendance WHERE course_id = 301 ORDER BY date_of_attendance DESC LIMIT 1
