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 problem_id FROM Problems
Feedback: Ensure corresponding date problem reported is beyond largest value of date problem reported by Rylan Homenick of staff table .

Ex Output:
SELECT T1.problem_id FROM problems AS T1 JOIN staff AS T2 ON T1.reported_by_staff_id = T2.staff_id WHERE date_problem_reported  >  ( SELECT max(date_problem_reported) FROM problems AS T3 JOIN staff AS T4 ON T3.reported_by_staff_id = T4.staff_id WHERE T4.staff_first_name = "Rylan" AND T4.staff_last_name = "Homenick" )


Ex Input:
SQL: SELECT Sex , Count ( * ) FROM Student WHERE Sex = "F" GROUP BY Sex
Feedback: In step 1 , find average age for both sex , in step 2 , find number of student whose age greater than step1 result .

Ex Output:
SELECT count(*) ,  sex FROM student WHERE age  >  (SELECT avg(age) FROM student) GROUP BY sex


Ex Input:
SQL: SELECT T2.date_incident_start FROM Students AS T1 JOIN Behavior_Incident AS T2 ON T1.student_id = T2.student_id WHERE T1.first_name = "Fanny"
Feedback: In step 1 you need to replace behavior incident with notes of assessment , alter date incident start with date of notes in step 2.

Ex Output:

SELECT T1.date_of_notes FROM Assessment_Notes AS T1 JOIN Students AS T2 ON T1.student_id  =  T2.student_id WHERE T2.first_name  =  "Fanny"
