In this task you are expected to provide an SQL statement from an english description of what that SQL statement does. The description may include multiple steps but you should only ouput one SQL statement that accomplishes every step. 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:
Step 1: For each row in Apartment_Buildings table, find the corresponding rows in Apartments table.
Step 2: find the number of rows in the results of step 1 whose apt_number equals Columbus Square and building_short_name equals Normandie Court

Ex Output:
SELECT Count ( * ) FROM Apartment_Buildings AS T1 JOIN Apartments AS T2 ON T1.building_id = T2.building_id WHERE T2.apt_number = "Columbus Square" AND T1.building_short_name = "Normandie Court"


Ex Input:
Step 1: find rows in employees table whose city equals IT Staff.
Step 2: find each value of city in the results of step 1 along with the  the corresponding rows to each value

Ex Output:
SELECT city , Count ( * ) FROM employees WHERE city = "IT Staff" GROUP BY city


Ex Input:
Step 1: For each row in Reviewer table, find the corresponding rows in Rating table.
Step 2: find name, stars of the results of step 1 whose stars equals 2.
Step 3: For each row in Movie table, find the corresponding rows in Rating table.
Step 4: find director of the results of step 3 whose stars equals 5.
Step 5: show the rows that are in both the results of step 2 and the results of step 4

Ex Output:

SELECT T1.name , T2.stars FROM Reviewer AS T1 JOIN Rating AS T2 ON T1.rID = T2.rID WHERE T2.stars = 2 INTERSECT SELECT T3.director FROM Movie AS T3 JOIN Rating AS T2 ON T3.mID = T2.mID WHERE T2.stars = 5
