Re: Faster HTML Output.

Mike,
I think a lot of us are thinking that you seem to be doing more than you need to...
On your screen, why not have a dropdown box for the fields they can search on, and a input text box for value. Read those 2 values in, Then:
select *
from sourcefile
where dropdownfield.selected = textfield.value

Then loop your cursor, and put the fields to the screen. You are currently looping over the source data once to extract it to the temp file, then reading the temp file to write to the screen... that is unnecessary. There really isn't a need for the temp file, just do your joins in the from clause. Make sure the keys you join on exist over the files you are using.

Brad is right, if a user is looking for this data, and its going to be an enormous amount of pages long, its their choice, to click it. Put a warning to the screen that the option takes a few minutes to run, thats all you can do.

Good luck

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.
