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.

Q: Step 1: For each row in employees table, find the corresponding rows in job_history table.
Step 2: find employees's EMPLOYEE_ID, END_DATE of the results of step 1 whose SALARY equals 24000

A: SELECT T1.EMPLOYEE_ID , T2.END_DATE FROM employees AS T1 JOIN job_history AS T2 ON T1.EMPLOYEE_ID = T2.EMPLOYEE_ID WHERE T1.SALARY = 24000

Q: Step 1: find the number of rows of each value of student_id in Student_Course_Attendance table.
Step 2: find student_id in Student_Course_Attendance table whose corresponding value in step 1 is greater than or equals 1

A: SELECT student_id FROM Student_Course_Attendance GROUP BY student_id HAVING Count ( * ) > = 1

Q: Step 1: For each row in Member_of_club table, find corresponding rows in Student table and in Club table.
Step 2: find Fname, LName of the results of step 1 whose ClubName equals Hopkins Student Enterprises

A:
SELECT T1.Fname , T1.LName FROM Student AS T1 JOIN Club AS T2 JOIN Member_of_club AS T3 ON T1.StuID = T3.StuID AND T3.ClubID = T2.ClubID WHERE T2.ClubName = "Hopkins Student Enterprises"
