How to create a "view" domain object in Grails

I'm trying to adapt a legacy database to a grails application and I'm not sure how can I do it on grails. I have a huge table (with columns colA, colB, ..., colZ) that I only want to map some of them as fields (say colA, colC, colE) like a database view, this domain class is intended to be read-only so it would not be a problem to not have the save, update and delete operations.

How should I create my domain class?

EDIT

I need to adapt a query to a domain object, this query has a lot of group by expressions (max, min, count, etc.) and I would like to adapt this query so that everytime I call DomainObj.list() Grails would run this query and load all the data from the database within the GORM proxy.

If it is read only, just create a domain object containing the fields you are interested in. That should be no problem.

Remember however that GORM will create a "version" column as default, but this can be disabled:

static mapping = {
      table 'people'
      version false
}
