Question

I am creating a view for a database for an assignment,

i keep getting this error in my code though.

CREATE VIEW Rental_View

SELECT Mo.Movie_ID, copy_id, mo.Movie_Name, format_name
FROM Movies AS mo JOIN copies AS co
ON mo.Movie_ID = co.movie_id  
JOIN format AS fo
ON co.Format_id = fo.format_id

SELECT c.customer_id, rental_ID, DATEDIFF (day, rental_date, return_date) AS  rental_duration' , c.first_name + ' ' + c.last_name AS customer_name
FROM Customers AS c INNER JOIN rentals AS r
ON c.customer_ID = r.customer_ID

In the first SELECT statement it is underlined red and i get the error

“Incorrect syntax near the keyword ‘SELECT’.”

i literally have no idea how to correct this as i am fairly new to SQL, any help would be much appreciated.

thanks in advance.

You need the AS keyword:

CREATE VIEW Rental_View   AS            --- <------ AS needed here

SELECT mo.Movie_ID                     --- mo, not Mo
     , co.copy_id                      --- play safe and declare which table 
     , mo.Movie_Name
     , fo.format_name                  --- are these two columns from
FROM Movies AS mo JOIN copies AS co
ON mo.Movie_ID = co.movie_id  
JOIN format AS fo
ON co.Format_id = fo.format_id  
;                                     --- add a ; if you want to
                                      --- run multiple statements

---

If you want to combine the two SELECT in one, you need to JOIN the tables from both, with something like this:

CREATE VIEW Rental_View   AS           

SELECT mo.Movie_ID                     
     , co.copy_id                      
     , mo.Movie_Name
     , fo.format_name                  
     , c.customer_id
     , rental_ID
     , DATEDIFF (day, rental_date, return_date) AS rental_duration 
     , c.first_name + ' ' + c.last_name AS customer_name
FROM Movies AS mo 
  JOIN copies AS co
    ON mo.Movie_ID = co.movie_id  
  JOIN format AS fo
    ON co.Format_id = fo.format_id  

  JOIN rentals AS r
    ON r.movie_id = mo.Movie_id        --- just a guess, you have to write this
  JOIN Customers AS c 
    ON c.customer_ID = r.customer_ID
