   • SQL UNION, UNION ALL

     UNION

     Example

     SELECT City FROM CustomersUNIONSELECT City FROM SuppliersORDER BY City;

     UNION ALL

     The UNION ALL command combines the result set of two or more SELECT statements (allows duplicate values).

   • SQL JOIN

     INNER JOIN

     The INNER JOIN command returns rows that have matching values in both tables.

     The following SQL selects all orders with customer information:

     Example

     SELECT Orders.OrderID, Customers.CustomerNameFROM OrdersINNER JOIN Customers ON Orders.CustomerID = Customers.CustomerID;

     Note: The INNER JOIN keyword selects all rows from both tables as long as there is a match between the columns. If there are records in the "Orders" table that do not have matches in "Customers", these orders will not be shown!

     The following SQL statement selects all orders with customer and shipper information:

     Example

     SELECT Orders.OrderID, Customers.CustomerName, Shippers.ShipperNameFROM Orders...
