I reformat the data here. Basically, I tried to output the data from table1 into table2 but not sure how to write it in oracle 8i. I am running Aqua Studio but the database backend is oracle.

If your intent is to transfer data from one table to another, use the insert..select command:

insert into table2 (col1, col2) select col1, col2 from table1;

Beyond that, it's just a matter of morphing the data to the desired format. SO has a plethora of questions on turning rows into columns.

In my opinion, this is usually a bad idea. I'm all for presenting data like this since your users may desire it but that's something that should be done in the presentation layer, not in the database.

Creating a table of this style (non third normal form) is usually enough for our DBAs to either reject the change outright or, at a minimum, bring you in for a stern taking to, which may include some ridicule and questioning of your parentage depending on how much sleep they had the night before :-)
