Procedure with variable number of columns


Posted on 16th Feb 2014 07:03 pm by admin

Hi, I have a procedure that looks like this:

PROCEDURE PROC(p_cursor OUT sys_refcursor)

And in the procedure, I build up QUERY dynamically and the number of columns varies at runtime.

At the end I do

OPEN p_cursor for QUERY
Then to call this, I'm doing

call PROC(?)

My question is, how would I go about running the query from this procedure, then adding rows or modifying the existing results, then returning the modified data?

What I want to do is add a new row based on some condition, so I still need to return a variable number of columns, but I need to modify the results before I return them.

Is there any way of doing this? I need to do some calculations on the columns (the variable columns), create a new row, insert into result set, and return this new result set.
