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.

Step 1: For each row in Individuals table, find the corresponding rows in Organization_Contact_Individuals table.
Step 2: find individual_last_name of the results of step 1 with largest value of date_contact_to
SELECT T1.individual_last_name FROM Individuals AS T1 JOIN Organization_Contact_Individuals AS T2 ON T1.individual_id = T2.individual_id ORDER BY T2.date_contact_to Desc LIMIT 1

find the catalog_entry_name, height of Catalog_Contents table for which price_in_dollars greater than 700
SELECT catalog_entry_name , height FROM Catalog_Contents WHERE price_in_dollars > 700

Step 1: For each row in Campuses table, find corresponding rows in discipline_enrollments table and in faculty table.
Step 2: find the summation of Graduate in the results of step 1 whose faculty's Year equals 2000 and faculty's Year equals San Jose State University

SELECT Sum ( T2.Graduate ) FROM Campuses AS T1 JOIN discipline_enrollments AS T2 ON T2.Campus = T1.Id JOIN faculty AS T3 ON T1.Id = T3.Campus WHERE T3.Year = "San Jose State University" AND T3.Year = 2000
