Sample Solution:
-- Selecting all columns from the person table with an alias 'e'
SELECT e.*
-- Ordering the result set by the LastName column in ascending order
FROM person.person AS e
ORDER BY LastName;
Explanation:
- The SELECT e.* statement retrieves all columns from the person table using the alias 'e'.
- FROM person.person AS e specifies the table from which the data will be retrieved, with "person" being the schema name and "person" being the table name. The alias 'e' is assigned to the table for easier reference.
- The ORDER BY LastName clause sorts the result set based on the LastName column in ascending order.
Sample Output:
