Invoke SQL Loader

Question

Hi,
I have an application where I use a SQL Loader to load data onto the table. When i log in as a regular user i try to invoke the SQL Loader on the server. For the credentials to connect to the server like username/Password@database to invoke the sqlldr it looks into a table. We had hard coded the admin username and password while passing these credentials to the server. So irrespective of which user logged in it would load data into the admin.tablename. But right now we want to change that and we want to load data into each users individual table.
For example if its user1 logged in .. when he does the data load it should load data into user1.tablename. So I assume i have to pass his credentials which connecting to the SQL loader instead of the admin. But we dont store any information of the user and their passwords in the application and there is no way we could retrieve password for each user. So if I dont have the password information of the user how would i connect to the server to run the SQL Loader. Could I pass the table name explicitly to the sqlldr instead of the .ctl file? Is there any work around to this as to how I could load data onto individual users tables.
Thanks and Regards

Well, since you hard coded the admin username, that admin username has INSERT ANY TABLE, yes? So all you need to do is create SQL*Loader control file specifying OWNER.TABLENAME as load table. For example, control file is:
load data
into table u1.example
fields terminated by ',' optionally enclosed by '"'
(col1 char(5),
col2 char(7))
{code}
Data file is:
{code}
hello,world,|
james,bond,|
{code}
Now:
{code}
SQL> show user
USER is "SCOTT"
SQL> create table u1.example(col1 varchar2(10),col2 varchar2(10))
  2  /
Table created.
SQL> host sqlldr scott/tiger data=c:\temp\example.txt control=c:\temp\example.ctl
SQL> select * from u1.example
  2  /
COL1       COL2
hello      world
james      bond
SQL>
{code}
