I have a number of sqlldr scripts and I have put most of them in the batch files. However, I donot want to save the passwords on the file
ie userid=scott/tiger@orcl
If I Just save as userid=scott@orcl, I am getting
12203- TNS:unable to connect to destination.

How do I proceed to have username and sid in the file but only the password should be prompted
please advise.
