NHibernate.Exceptions.GenericADOException错误代码

Question

I am developing application in C # with NHibernate and SQLServer. I got this exception:

could not update: [MyApp.Client # 94] [SQL: UPDATE [Client] ...

The exception is caused by a unique key index in the client code field.

I want to know if exists any reference to the list of error codes nhibernate|hibernate. Example: #94 --> unique key restriction I keep getting access SQLException to check that it is unique key constraint.

Answer 1

I think the number 94 is not an error code, the message is trying to point you to the problematic object causing the error. By the way is this a web application, you should use Merge instead of update.
