Cursor and subfile

bogeybetsy — Tue, 25 Aug 2009 16:32:46 +0000

I am using a cursor to get records for display through a per-page-loading subfile. I am using a host structure to get the records. My problem is how to “position to” a specific record. Cursors do not support functionality similar to what a SetLL and ReadE can do. When I close, prepare a new query, and re-open the cursor, the time to retrieve the new set of records with the record I am searching for on top of the subfile take more than a minute to display. Is there a better way to do this without going back to RLA (SetLL and ReadE)? Also, the maximum number of records that fit on the screen is 19. So I retrieve only 19 records per close-&-then-open of the cursor. When I do not fetch for 19 records only but load all file records in the cursor and then just fetch for PAGE UP and PAGE DN, wouldn’t I be eating up a lot of memory – I mean what happens if I have multiple users?

Alternatives to cursors in SQL Server

What are the alternatives to cursors? I can’t find any other method to move through record sets one at a time.

Bulk Collect loop and Cursor Loop

Nikhildhar — Mon, 29 Dec 2008 09:58:26 +0000

Why there is such a huge performace difference between Collection loop and a cursor Loop? Why collection populated using Bulk collect is way faster?
Detailed explaination will be helpful.

What causes ora-00904 error on valid fields when querying across dblink in a cursor

Tom msu — Thu, 12 Jun 2008 23:18:17 +0000

I have a procedure that contains a cursor that runs in a cursor for loop. The select query runs fine over the dblink all by itself, but when I try to compile the procedure, I get the PL/SQL: ORA-00904: invalid identifier on the column names. I can do a describe on the table over the link and all of the columns are there.
