The following walks through how you sign on to a STUDENT Workspace with Oracle’s APEX product and write and run free-form SQL statements. You can find instructions on how to create your own STUDENT Workspace.
While this blog introduces several concepts and features of Oracle APEX, it only focuses on how to write and run free-form SQL statements. Overall, Oracle APEX is a valuable tool to learn and master.
In a prior post, I showed you how to access Oracle Database 11g XE APEX. This post shows you how to create a basic workspace against a student database (or, what Oracle lables a schema, which is synonymous with a database).
