Database Access Statements
In 4GL, you use these QUEL statements to query the database:
•
The Retrieve Statement
•
Using Append to Add Data to Database Tables

These statements enable you to retrieve data, append rows to tables, update rows in tables, and delete information that is no longer needed.
