RE: Creating a sorted table
Sure, and thanks. I appreciate the corrections, as one problem with doing this for a while is the aggregation of useless and no longer true "facts", which I'm finding I have more and more of. They feel like barnacles. :) I've finally decided to go get my OCP, which I hope will help scrape some of the buggers off. This list always helps, too.

it can dramatically improve your buffer

Re: Creating a sorted table
Well, it won't work in all cases, but I have on occasion used as a shortcut: INSERT INTO ...

Re: Creating a sorted table
Whyever would you want data inserted in order? There is no guarantee that Oracle will actually store the records "in order", there is no performance gain, and you can always retrieve the records in order by using an order by statement -- if you really need ordered data, you could use a index-organized table with all of your columns, with the date as the first column. But methinks this would be dangerous for a heavy transaction table. (Gurus, please correct me if I'm wrong here) However, if you are still keen, you could do this through a PL/SQL block, something like the following: declare cursor get_data is select col1, col2, col3, ... from unordered_table order by whatever; begin for dataRec in get_data loop insert into ordered_table (col1, col2, col3, ...) values (dataRec.col1, dataRec.col2, dataRec.col3, ...) end loop; end; / Cheers!

Creating a sorted table
We have un-ordered data in a table that needs to be inserted into a transaction table in order of the date that the transaction took place. Oracle does not allow "INSERT . AS SELECT . ORDER BY." or "CREATE TMP_TABLE . AS SELECT . ORDER BY.." Is there a method by which I can accomplish this.
