hi!
Having a schema using hilo. What is the best way to allow inserts
outside the app by for example a dba using ssms?
I guess i could implement hilo in tsql?
Please let me know if you had any experience with this

How do I map a relation on a UniqueKey in the foreign Table?
I mean sth. like this:

Take care. The matter is not only the representation but how the

Well, I ended up creating a simple enhanced usertype converting from string

Am I correct to assume that IEnhancedUserType is the right approach for a

is not with a data.

Hi guys!
I have a question.
My IDs are GUID but a specific property is an index column.
This column uses Oracle´s Sequence.
My question is: How to use a Oracle`s Sequence into a property?

Thank you.
Bruno.
I don't think somebody should fix that issue (more... somebody should
close it as won't fix).A component with all properties null is nothing
(mean is null it self).
There is another possibility... a component is always created even when all
properties are null (this is not the way NH is working).
