List of Value (LOV) Embedded Comma, Semicolon, Colon

Question

I have an LOV that is to return an Employee Name in the format "Last_Name, First_Name Middle_Name" with a comma after the last name and a space between the First_Name and Middle_Name. Basically, my LOV is Employee_Name and Employee_Id.
However, I cannot get the "comma" to appear after the Last_Name. I can get an asteric (as in the following code) but cannot get a comma, semicolon or colon. Is there something special I have to do to get the comma?RETURN  'SELECT  DECODE((FIRST_NAME_TX
             ||  MIDDLE_NAME_TX
             ||  LAST_NAME_TX),NULL,''Not Available''
              ,  LAST_NAME_TX||''* ''
             ||  FIRST_NAME_TX||'' ''
             ||  MIDDLE_NAME_TX) EMPLOYEE_NAME
              ,  EMPLOYEE_ID
           FROM  EMPLOYEE
          WHERE  LOGICAL_DELETE_IND = ''N''
          ORDER  BY EMPLOYEE_NAME ' ;

Answer 1

In my case using REPLACE function solved the problem:
Let's assume that the +<full_name>+ has the comma that the tabular form fails to dispaly.
Instead of using in LOV:
select <full_name> d, <id> r
from <your_table>
I used:
select REPLACE(<full_name>, ',', '<my_string>') d, <id> r
from <your_table>
The +<my_string>+ conists of *& # 44* with no spaces in between. I have to explain it this way because even on this site +<my_string>+ gets replaced with a comma and you can't see how I did it.
Hope this helps.
