Hi, I am new to this community. I have successfully managed getting data from the database, but am still having problem to insert data into it. When I save data (see the code below), the NHibernate seems generates a parameterized insert statement (see below). And that “Commit” execution throws an exception (ORA-00928: missing SELECT keyword). When I copy and the paste the generated insert statement to the SQLPlus, I get the same error. But if I use the regular insert statement (with columns and values). It works fine. So, I am wondering is the NHibernate generating the correct insert statement for me. If it does not, did I miss any setting? During my debugging process, at a point I have to specify the assembly binding to Oracle.DataAccess in the runtime section of the configuration. Does this raise any warning?
Here is the related configuration

session.Save(wfi);
