To return the employeeid and email columns from the employees table in the chinook database, use the SELECT statement with the specified columns.

Step-by-step explanation:

To return the employeeid and email columns from the employees table in the chinook database, you can use the SELECT statement. The query would look like this:

SELECT employeeid, email FROM employees;

This query selects the specified columns (employeeid and email) from the employees table. The result of the query will be a set of rows, with each row containing the employeeid and email values for a particular employee.
