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. 

Example Input: SQL: SELECT title , credits , dept_name FROM course GROUP BY dept_name HAVING Count ( * ) > 1
Feedback: Find number of rows of each value of course id in prerequisite table in step 1.
Example Output: SELECT T1.title ,  T1.credits , T1.dept_name FROM course AS T1 JOIN prereq AS T2 ON T1.course_id  =  T2.course_id GROUP BY T2.course_id HAVING count(*)  >  1

Example Input: SQL: SELECT address_line_2 , email_address FROM Customers WHERE email_address = "hsteuber@example.org" INTERSECT SELECT address_line_2 , email_address FROM Customers WHERE email_address = "vbogisich@example.org"
Feedback: Catch only address line 1 in step1 and address line 2 in step2 , email address must be vbogisich@example . org .
Example Output: SELECT address_line_1 ,  address_line_2 FROM customers WHERE email_address  =  "vbogisich@example.org"

Example Input: SQL: SELECT T1.formats FROM files AS T1 JOIN song AS T2 ON T1.f_id = T2.f_id WHERE T2.resolution < 1000
Feedback: song name of song should be used , not formats and format should be of mp 3.
Example Output:
SELECT T2.song_name FROM files AS T1 JOIN song AS T2 ON T1.f_id  =  T2.f_id WHERE T1.formats  =  "mp3" INTERSECT SELECT song_name FROM song WHERE resolution  <  1000
