Darian,
There isn't a command-line parameter you can pass to Orion to get it to do this, but
as was shared with me on this list there's a really nice _free_ utility that does
this. It's called p6spy and is located at http://www.provision6.com/
I don't know about your second question, we've nev
Is there a directive to add on the command line to make Orion log all
generated SQL statements?
Also, if I have a EJB CMP and I am writing a finder method and I want to
pass a JavaBean as a parameter, how do I tell the finder which method or
variable to use in the where clause? Is it possible to
Neither is LIMIT supported by standard SQL, so it would reduce portability
to use it in the generated SQL as well.

You could either edit the orion-ejb-jar.xml. And change the generated
SQL, but this will be overwritten next time orion is started. Another
way is to specify a finder query in your EJBHome inteface like this:

Hi all,
Is there possibility to set a maximum row count for a resultset ?

Title: Errors on EJB Finder Methods
If you are doing a find ... and lets say it cant find anything.
IT seems to throw an exception ... is there anway to make it just null ... so i can do something else instead?

- not all queries can be coded
with CMP finder methods ( consider example: I need to extract 20 records,
starting with 500 out of 3000 records in a table. Using Collection would be
extremely expensive ).

The orion finders are wonderfully straightforward in this regard (joins
across entities), but you have to be a bit careful. Here's a quick example.
An Employee bean has a reference to Office. The Office bean has an int
numStaff attribute. I want to define a finder method that shows me all

Hello,
Does anyone on this list know if an EB using an Entity Reference as an
attribute, can have a finder method
search on that attribute? If so can you search on attributes of the
afore mentioned entity reference?

you should allways set the field name first ie. "$name = $1" because of the
database optimizer.
2) when using like keyword the best way to use it is to inform the users
that % is the wildchar and then you will soon see some extremely cool usage
of your finder methods :) ive seen
Hi Sven,
The field names should be the "name", not the "persistence-name". So you
should use "$1 = $_fantasia". You can check this by viewing the generated
SQL after deployment.
I'm not sure about the LIKE construction - but it sounds reasonable.

If you have name, age and score, you may end up with finder methods like:
findB
The normal way of doing this is by implementing several finder methods, and
let a session bean do the entity querying..
For searching on names with wildchars just do:
query = "$name like $1"
this will actually serve as several finder methods (see examples under).

I'm running into trouble specifying finder queries in orion-ejb-jar. As far
as I can make sense of it the cause is in the quotes. Is that correct and
does anyone know how the get around that?
I've changed the default finder method to:
you put these in the orion-ejb-jar.xml file using EJB2.0 types QL.

Congratulations on releasing v1.0.
It is a nice feature that orion writes the custom finders for CMP in some
