Can't Access a Ref Cursor Column

Asked by dvcom in Oracle Database

Tags: ref

Hi,

I am generating a report in ASP.NET. For this purpose, i created a stored procedure that returns a reference cursor to ASP.NET page and then ASP.NET page assign that reference cursor to a data reader and this data reader is then assigned to a grid. Now the problem is that when the data amount is huge, the ASP.NET page returns the errors either "Object Reference is not set to an Instance" or "Invalid Operation: Data reader is closed". Now, i have thought a solution that i don't want to return a ref cursor to ASP.NET page, i want that when the cursor is populated with data at database end, then i want to create a text file via UTL file package on the server from that ref cursor and then my ASP.NET page will download that file.
The problem is that i can't access ref cursor columns. I want a generic function, that just gets a cursor (no matter how many columns the cursor has) and UTL file process starts and create a text file from the ref cursor.

I know how to access a row of cursor. i.e.

FETCH MyCursor INTO a, b;

but by this way, i am bound to ref cursor columns.
Is there any way like we do in a matrix.......i.e.

FOR i=0 to MaxRowsOfCursor-1
FOR j=0 to MaxColsOfCursor-1
UTL_FILE.PUT(pFile, MyCursor(i)(j));
NEXT j
NEXT i
