Gunnar.
Thanks for the reply.
Sorry man but I didn't show you that the "*select ... *" code snip is in
the create view code in SQL. Not in the application code.
I figured out what your perspective by re-writing my access, from the nice
simple model construction, to now using a call to hbmSession.CreateQuery().
*Can you answer this question?*
This doesn't work:
var qry = ses.CreateQuery("select CustServSetRecid from vCustServSet order
by CustServSetRecid")
.SetResultTransformer(NHibernate.Transform.Transformers.AliasToBean(typeof(vCustServSet)))
.List<vCustServSet>();
error stating *can't find getter for propert '0'* (property 0?)
But this does:
var qry = ses.CreateQuery("select CustServSetRecid *as CustServSetRecid*
from vCustServSet order by CustServSetRecid")
.SetResultTransformer(NHibernate.Transform.Transformers.AliasToBean(typeof(vCustServSet)))
.List<vCustServSet>();
And yes this does not work, nHibernate doesn't parse out the semi-quotes in:
var qry = ses.CreateQuery("select CustServSetRecid as *'CustServSetRecid'*
from vCustServSet order by CustServSetRecid")
.SetResultTransformer(NHibernate.Transform.Transformers.AliasToBean(typeof(vCustServSet)))
.List<vCustServSet>();
But it doesn't make sense that all columns in a CreateQuery() will need an
alias.
Everyone here is scratching their heads. Such requirements just don;t seem
to make sense.
