This is because @@ROWCOUNT is specific of Sql Server, you should use whatever equivalent in oracle to return the number of record affected.

Remember that when you use CreateSqlQuery you are actually losing many of the advantages of an orm, and you become “database dependant”

I tried to execute a query that ends with “select @@ROWCOUNT count;” and I got the following exception: “System.Data.OracleClient.OracleException: ORA-00911″- Invalid character.

I use NHibernate.Dialect.OracleDialect.

Great…it is just what I need.

ISession.Delete will load the object first, whilst CreateSQLQuery will delete the data directly.

We can use windbg to view the memeory to verify these 2 situations.
