instruction:
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.
question:
Step 1: For each row in Tourist_Attractions table, find corresponding rows in Locations table and in Street_Markets table.
Step 2: find Market_Details of the results of step 1 whose Market_Details equals walk or Location_Name equals bus
answer:
SELECT T3.Market_Details FROM Locations AS T1 JOIN Tourist_Attractions AS T2 ON T1.Location_ID = T2.Location_ID JOIN Street_Markets AS T3 ON T2.Tourist_Attraction_ID = T3.Market_ID WHERE T3.Market_Details = "walk" OR T1.Location_Name = "bus"


question:
Step 1: For each row in Manufacturers table, find the corresponding rows in Products table.
Step 2: find Manufacturers's Name of the results of step 1 whose Price greater than 200 or Price less than 240
answer:
SELECT T1.Name FROM Manufacturers AS T1 JOIN Products AS T2 ON T1.Code = T2.Manufacturer WHERE T2.Price > 240 OR T2.Price < 200


question:
Step 1: For each row in department table, find corresponding rows in course table and in instructor table.
Step 2: find name of the results of step 1 whose title equals C Programming
answer:

SELECT T3.name FROM department AS T1 JOIN course AS T2 ON T2.dept_name = T1.dept_name JOIN instructor AS T3 ON T1.dept_name = T3.dept_name WHERE T2.title = "C Programming"
