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.

Question: SQL: SELECT apt_number FROM Apartments GROUP BY apt_number ORDER BY Count ( * ) Desc LIMIT 1
Feedback: Replace apartment number with bedroom count in step 1.

Answer: SELECT apt_number FROM Apartments ORDER BY bedroom_count DESC LIMIT 1


Question: SQL: SELECT Continent FROM country GROUP BY Continent ORDER BY Count ( * ) Desc LIMIT 1
Feedback: Need to find country's name where maximum languages are used in that country .

Answer: SELECT T1.Name FROM country AS T1 JOIN countrylanguage AS T2 ON T1.Code  =  T2.CountryCode GROUP BY T1.Name ORDER BY COUNT(*) DESC LIMIT 1


Question: SQL: SELECT T2.Fname FROM Faculty_Participates_in AS T1 JOIN Faculty AS T2 ON T1.FacID = T2.FacID GROUP BY T1.FacID HAVING Count ( * ) > = "Canoeing"
Feedback: In step 2 it should find faculty participates in student id and in step 3 it should apply condition which says corresponding activity name equals to Canoeing or Kayaking .

Answer:
SELECT DISTINCT T1.lname FROM Faculty AS T1 JOIN Faculty_participates_in AS T2 ON T1.facID  =  T2.facID JOIN activity AS T3 ON T2.actid  =  T2.actid WHERE T3.activity_name  =  'Canoeing' OR T3.activity_name  =  'Kayaking'
