Query Output Formatting Help

Question

Hello All,
I'm having problems trying to format the output of one of my queries. I'm new to SQL and I consider my writing the query a HUGE win.... but I can't seem to get the correct output format.
Per the code below, it is outputting the Last Name (lname) of the employee, a count of what I want, and the overall rank.  I would like to concatenate the employee number (emp#) the first (fname) and last name (lname) together into the same column in the output.
The concatenation code would be something like the below.
Desired concatenation:
emp# || ' - ' || lname || ', ' || fname AS EMPLOYEE
I'm using Oracle 11g Express. Please let me know if you need any supporting information to assist you.
I appreciate all your help!!! Thank you.
Query
SELECT EMPLOYEE, PREPARED,
RANK() OVER (ORDER BY Prepared DESC) AS rank
FROM (SELECT lname EMPLOYEE , COUNT(DISTINCT reportnum) PREPARED
      FROM employee
      LEFT OUTER JOIN faultreport USING (empno)
      GROUP BY lname
      ORDER BY Prepared DESC)
WHERE rownum < 15;

Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

It looks like you've found the right way to concatenate the columns.  How to use that in your query depends on your data, and what you want the query to do with that data.
If you GROUP BY lname, what do you want the concatenated value to be when different rows having the same lname have different fnames and/or emp#s?
Do you want to GROUP BY the new concatenated employee instead of lname?
