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.course_name FROM Courses AS T1 WHERE T1.course_name NOT IN ( SELECT T2.semester_name FROM Semesters AS T2 )
Feedback: Find those semester name whose semester id not present in student enrolment table .
SELECT semester_name FROM Semesters WHERE semester_id NOT IN( SELECT semester_id FROM Student_Enrolment )

SQL: SELECT property_name FROM Properties WHERE room_count > 1
Feedback: Be assured to look for code of property type which are  equivalent to houses or apartments alone.
SELECT property_name FROM Properties WHERE property_type_code  =  "House" UNION SELECT property_name FROM Properties WHERE property_type_code  =  "Apartment" AND room_count  >  1

SQL: SELECT DISTINCT T2.positionText FROM races AS T1 JOIN constructorStandings AS T2 ON T2.raceId = T1.raceId JOIN constructorResults AS T3 ON T1.raceId = T3.raceId WHERE T3.raceId = 1
Feedback: Replace constructor results with driver standings , position text with forename , race id with wins , also make sure position equals standing .

SELECT DISTINCT T1.forename FROM drivers AS T1 JOIN driverstandings AS T2 ON T1.driverid = T2.driverid WHERE T2.position = 1 AND T2.wins = 1
