I'm new to Oracle and PL/SQL and have the following question:
If I have a web application in either Java using JDBC or Cold Fusion and I code a SQL SELECT statement, can I use a PL/SQL function that I have stored on that server and granted access to. If for instance I create a hash function so that social security numbers won't be stored in clear text, can I code
SELECT * FROM EMPLOYEES WHERE SSN=hash(ssn);
An online tutorial said that I can't issue that sort of SELECT statement from the SQLPlus prompt -- is that kind of select statement invalid from any place SQL might be used?

Do you happen to know, was the tutorial I saw that said you can't use a PL/SQL function in a SQL statement issued from the SQLPlus prompt, accurate? If it is accurate, I was wondering why a PL/SQL function being used in a SQL statement would be valid in some environments, but not from the SQLPlus prompt.
