.net - NHibernate - Custom render a column name on SQL -


i have 2 tables, say:

mytable                         myfktable ---------------------------     -------------------------- id             numeric(3,0)     id             varchar(3) description    varchar(100)     description    varchar(100) fk_id          char(3)

note in example, mytable.fk_id references myfktable.id, respective datatypes don't match.

so, when have trimmed id string value in myfktable, need join both tables way:

select (...)  mytable       inner join myfktable on (mytable.fk_id = cast(myfktable.id char(3)) (...)

the question:

is there way "quote" (surround) column name specific sql function (in case, cast function)?

i've found following difficulties researching this:

  • i create specific dialect, great, because can switch in configurations when normalize database. problem is, quote , related overridable functions won't give me enough information table each column nor tells me da column-to-be-quoted datatype;

  • i create specifica iusertype these cases, none of methods implemented step in how column name in rendered in final sql.

  • i know can set sql column name (how render) via mapping, wish avoid solution check if there other ways of doing this.

what possibilities?

disclaimer

i'm aware should normalize database schema - unfortunately, i'm not allowed @ present moment. i'm aware not best solution, or might incur in performance issues. i'm curious if type of adaptation in nhibernate real possibility.
