Question 18Suppose you have a table called D with the schema/header (c1 TEXT, c2 TEXT, dist REAL).c1 andc2 represent the names of cities and dist represents the distance between them in miles. Beloware several attempts to write a SQL query to get the distances of all three-city trips. (That meansthey start in one city, travel to second city, and then end in a third city.)Which of the following queries will work to retrieve this information?(Select all correct answers; there may be more than one.)SELECT D.c1,D.c2,E.c2,D.dist FROM D , D as E WHERE D.c2=E.c1SELECT c1,c2,c2,dist+dist FROM D,D WHERE c1=c2SELECT D.c1,D.c2,E.c2,D.dist+E.dist FROM D, D as E WHERE D.c2=E.c1SELECT D.c1,D.c2,E.c2,x FROM D, D as E WHERE x=D.dist+E.distSELECT D.c1,D.c2%3DE.c1,E.c2 FROM D, D as E WHERE D.dist+E.distO This is not a task that can be solved with a SQL query. You have to use Python code.This can be done with a SQL query, but none of the above queries will work.

The query that will work are given below:

Imagine that you are a database manager at a company that makes custom shirts. One column in the database lists the wholesale price of the shirts. A second column lists the labor charge, which is currently set to 11 percent of the wholesale price of the shirt. A third column lists the retail price of the shirt, which is the combination of the wholesale price and the labor charge. Write the statements that calculate the values that belongs in the second and third columns. How could you use a query to format these columns?

The given SQL creates a Song table and inserts some songs. The first SELECT statement selects songs released after 1992. The second SELECT statement selects the release year for song with ID 800. Create a third query that combines the two existing queries. The first SELECT should be the outer query, and the second SELECT should be the subquery. The ORDER BY clause should appear after the subquery. Run your solution and verify the new query returns a result table with five rows, all with release years after 1992. CREATE TABLE Song (ID INT,Title VARCHAR(60),Artist VARCHAR(60),ReleaseYear INT,Genre VARCHAR(20),PRIMARY KEY (ID)); INSERT INTO Song VALUES(100, 'Hey Jude', 'Beatles', 1968, 'pop rock'),(200, 'You Belong With Me', 'Taylor Swift', 2008, 'country pop'),(300, 'You\'re Still the One', 'Shania Twain', 1998, 'country pop'),(400, 'Need You Now', 'Lady Antebellum', 2011, 'country pop'),(500, 'You\'ve Lost That Lovin\' Feeling', 'The Righteous Brothers', 1964, 'R&B'),(600, 'That\'s…
