I am learning SQL at school. I need to work with Oracle 8.0 or any other version before 9i. I have tried to do it, but just came to know that its antique. Hence I need your help to download it. Kindly give me the link.

Oracle is a commercial product, surely you aren't asking for a pirated version?

Is there any difference in the commands or functioning of SQL PLUS in 10g when compared to 9i or prior versions?
