You might have column names that you do not want to retain in the results of your SQL statement. For example, your database is set up with a column that uses a reserved word in ColdFusion, such as EQ. In this case, you can rename the column as part of the query, as follows:
SELECT EmpID, LastName, EQ as MyEQ FROM employees
The results returned by this query contains columns named EmpID, LastName, and MyEQ.
