Hi Theodore,
this is no big deal I hope. First you have to create a model for your
entities, for example with a names-entity, a businessmetadata-entity and a
to-n-relationship from names to businessmetadata (or is it 1:1?). Then you
generate your code and the rest is simple: create a query on the
names-object with 1 qualifier:
new EOKeyValueQualifier("businessmetadata.isCurrent",
EOQualifier.QualifierOperatorEqual, Boolean.True);
Where businessmetadata is the name of the relationship and isCurrent the
name of the attribute. Hope its right, its just as I am remembering it and
well, its of course simple WO - I am not sure how good you know this stuff
so sorry if I have misunderstood you problem ..
Ciao,
Bjoern

Betreff: help needed with query
First, most of my experience is with cocoa. I could write any query I wanted
even across relationships. I am having a problem with relationship in WO.
I am starting out with a new simple setup. My db is normalized like this
table names:
firstname text
lastname text
nameid (serial)
namesbusinessmeta:
iscurrent bool default true
phonenumber text
extension text
nbmid
namesFKid foreign key to names
I have a trigger and function on the db that creates a new insert into
namesbusinessmeta with the referenced foreign key on insert into the names
table.
This works fine.
but now I want to query from my WO app.
select * from names where nameid in (select namesFKid from namesbusinessmeta
where iscurrent = true) order by lastname;
I am lost.... I want an array of current employees where the iscurrent bool
is in relationship table.
Maybe I am barking up the wrong tree......
Ted
