Re: Dynamic PL/SQL - Get values from one cursor from another or alternatives?

In my experience, with 10g (don't know if they fixed any of this in 11):

Not in my experience (and I have tried).

No. You can get the names of all of the columns of your table by querying USER_TAB_COLS (or ALL_TAB_COLS, depending on what you're working with), though. Unfortunately, as far as I know, as of 10g at least, you have to hard-code the column names.

... and, no on this one too.

However, assuming your table structure is not in flux, you can make gratuitous use of USER_TAB_COLS and some java on your oracle db to convert some cursor data into a useable array type that includes both col names and data (depending on how you want to do it). I have done this before on a previous project, and it can work, it's just a little more work and a lot less intuitive; pl/sql is limited in some ways that I find very unfortunate. At least, as of and including 10g.
