Inserting Data with the SQL INSERT Command

The INSERT command in SQL is used to add records to an existing table. Imagine that our HR department needs to add a new employee to their database. They could use a command similar to the one shown below:

INSERT INTO personal_info
values('bart','simpson',12345,$45000)

Note that there are four values specified for the record. These correspond to the table attributes in the order they were defined: first_name, last_name, employee_id, and salary.
