Solution
The problem statement is asking to create a SQL view that displays pairs of cities where customers and salesmen are located. The view should be created from two tables: salesman and customer.
Here is a step-by-step guide on how to create the view:
-
Identify the relevant columns in the tables: From the problem statement, we can see that we need the city information from both the salesman and customer tables.
-
Write the SQL query to join the tables: We need to join the salesman and customer tables on the city column. This can be done using an INNER JOIN clause in SQL.
-
Create the view: Once we have the SQL query, we can create the view using the CREATE VIEW statement in SQL.
Here is the SQL query to create the view:
CREATE VIEW city_pairs AS
SELECT customer.custcity, salesman.salescity
FROM customer
INNER JOIN salesman ON customer.custcity = salesman.salescity;
This query creates a view named 'city_pairs' that displays pairs of cities where customers and salesmen are located. The SELECT statement selects the 'custcity' column from the 'customer' table and the 'salescity' column from the 'salesman' table. The INNER JOIN clause joins the 'customer' and 'salesman' tables on the 'custcity' and 'salescity' columns.
Please note that the actual SQL query might vary depending on the exact structure and content of your 'salesman' and 'customer' tables.
