It’s not uncommon to reference the current user as
USER in your PL/SQL code. A simple use case may be to determine the client or environment that you’re running in (ex: dev, test, prod).
USER will have some slight side effects when running the code in APEX as the current
USER is actually
APEX_PUBLIC_USER (or what ever user you configured). This can cause issues in your application. To resolve it, simply reference
-- Via SQL*Plus
If you run the same query in APEX the output is shown below. You’ll notice that referencing
USER it does not display my current schema (
GIFFY in this case).
This can be really tough to detect in automated tests as when testing via SQL*Plus,
USER will return the current schema name.
