nhibernate - Avoiding NULL object in HQL Query where clause -

-

I have an organization that can be a basic unit. I want to run this query:

Select the unit where entity.parent.id = 9

there are no parent in the institution (entity.parent = null ) And N. Hibernate Fail to run this query (QueryException - Property can not be resolved)

I used HQL to retrieve all the 9 IDs that prevent people with parental null How can i use

(entity.parent.id = 9 results before the same exception, the entity entry is not empty)

There is an option to use nested selection statements but I It does not seem to be the most efficient solution.

You are missing from from HQL query trying to write it this way Do:

From the unit where the unit peer is not empty and entity.parent.id = 9

is not definite, but perhaps unit peer Is not empty part is not necessary I think NHibernate will handle this scenario.

The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
