I have several user defined functions which are referenced in triggers
and views. For software upgrades, I need to be able to drop the
triggers and views which reference these user defined functions, then
drop and recreate the user defined functions, then recreate all the
views and triggers. I don't imiagine I'm the first person who needed
to do this, and I don't have a lot of db2 experience, so I wanted to
see if there is a common or generally used technique for handling this.
This will be part of the upgrade process in a commercial software
product, so it has to be a programmatic technique, not something done
from the Control center. I have metadata tables which can tell me the
names of all the views and triggers that I need to drop and recreate,
so I don't need a way of finding which views and triggers need to be
recreated, just the ablility to drop and recreate the ones I specify.
This is for DB2 8.1.
Thanks in advance for any advice.

Have a look at 'db2look' utility. it extracts the ddl of views,
triggers and udfs and can store them in a plain ascii file. once
extracted, you can then later recreate those objects by executing this
ddl file. the relevant commands would be similar to:
db2look -d SAMPLE -e -o sample.ddl -p -a
db2 -tfv sample.ddl

May sound irrelevent, but . . .
<<db2look -d SAMPLE -e -o sample.ddl -p -a
<<db2 -tfv sample.ddl>>
Where does one find documentation for all such utilities for DB2 with
their switches and options? (Immediateley I'd like to find them for
db2, but also for Webshpere and everything else that IBM publishes.)

Stanley, try: db2look -h
It lists all options, their meaning and also some examples.

If I have all sorts of triggers and constraints,
The only way to have them applied incrementally to the data during

is to do the bulk load via individual INSERT statements,
or by restoring by incremental sections,
correct?

Situation two schemas:

Hello,
I am building an application for Windows Forms using. I am new to SQL
Server 'Views'. Are the following correct understanding of their use?
1.) I believe a view can be referenced in a stored procedure something
like this;
Select * from View1
Is that true?

Fellow database developers,
I would like to draw on your experience with views. I have a database
that includes many views. Sometimes, views contains other views, and
those views in turn may contain views. In fact, I have some views in
my database that are a product of nested views of up to 6 levels deep!
The reason we did this was.
1. Object-oriented in nature. Makes it easy to work with them.
