Sample Solution:
-- This SQL query selects the TerritoryID from the salesterritory table and the SalesOrderID from the salesorderheader table. It performs a CROSS JOIN between the two tables, generating a Cartesian product of all rows from both tables. It orders the results by SalesOrderID.
-- Selecting TerritoryID from the salesterritory table and SalesOrderID from the salesorderheader table.
SELECT dst.Territoryid, fis.SalesOrderid
-- Performing a CROSS JOIN between the salesterritory table (aliased as 'dst') and the salesorderheader table (aliased as 'fis').
FROM sales.salesterritory AS dst
CROSS JOIN sales.salesorderheader AS fis
-- Ordering the results by SalesOrderID.
ORDER BY fis.SalesOrderid;
Explanation:
- The query retrieves the TerritoryID from the salesterritory table (aliased as 'dst') and the SalesOrderID from the salesorderheader table (aliased as 'fis').
- A CROSS JOIN is used to combine each row from the salesterritory table with every row from the salesorderheader table, resulting in a Cartesian product.
- Unlike other join types, CROSS JOIN does not use any condition to match rows from the two tables; it simply combines all possible combinations of rows.
- The result set contains all combinations of TerritoryID and SalesOrderID from the two tables.
- The results are ordered by SalesOrderID.
Sample Output:
