Totaling record items in a multi-record detail block

1.)  When Oracle Forms returns rows for a multi-record base table block, will looping through the records in the block read all rows in the originating cursor or only the rows fetched into the block.
ie: multi-record block, items displayed = 4
                        items buffered = 7
                        rows = 500 in database
So, if I want to total a column in all rows, would it be correct to loop through the block or query the database?

Hi,

Oracle form is crap at retrieving the number of record a query might fetch. But I wouldn't recommended looping thru the block to get a total. (more network traffic, slow down the client / server). What I would do is to total a column in a separate query in a procedure I would create in program units. That will improve radically the speed (well still depends how much records you have, and if there is a lot it might be a good idea to have a index on the where clause you are using to sum the column...)

Thanks for the help, it was greatly appreciated.  I was thinking about doing the totals in a program unit procedure, you have just  convinced me to do that.
