I don't think it is a good idea to build an index that will be used only once.
It will be better to add "ORDER BY" in the SQL that populates the table, or use SQL to read the temp.

The reason for using the temp table is a pretty big one. We do not do
logical DDS joins in our shop. The ordering the user wants is over fields
in multiple files. So as I stated, I'm creating a temp table, then
creating indexes over that empty temp table, then executing the select into
that temp table. BTW, the user is wanting to sort the data one of three
ways.

If you can read through a cursor faster than regular I/O please inform me,
cuz as I see it... I still have to loop the same amount of times.

Also, I was always thought, you'd get better execute time when you select
the data you need from large tables into a temp table.

Many of us have lived in this space a looong time - don't assume that we
haven't heard your request, we are just digging deeper because we don't

like

your current implementation (i.e. temp file) which many of us believe

could

potentially be eliminated.


Cursor read or regular I/O doesn't make a difference.

Could make all the difference.



For some reason, I thought that in V5R4, or another version, you were

given the ability to do a SELECT ... FOR XML

I have heard of this feature in some of the WebSphere/Rational SQL

tooling,

but have not used it. I don't believe it is part of i5OS but instead a

set

of Java .jar files that offer the functionality.

It helps with getting it off the server faster and puts the burden on the
client's computer. Has I have said and some of you guys keep

forgetting...

the problem is not getting the data with the SQL statement. The problem

is

reading the large amount of data. So to use the suggestion of "not"

using

the temp table doesn't help. Cursor read or regular I/O doesn't make a
difference.

For some reason, I thought that in V5R4, or another version, you were

given

the ability to do a SELECT ... FOR XML (or something similar to that).

But

I haven't found any documentation on it.
