my view is like this.

view name: testview
col1 int,
col2 varchat(50),

Answer 1

Assuming col1 is the primary key:

class View {
    Integer col1
    String col2
    Date col3

    static mapping = {
        table name: "testview"
        version false
        id name: "col1", generator: "assigned"

        // These are unnecessary unless you change the name of the fields
        col1 column: "col1"
        col2 column: "col2"
        col3 column: "col3"
    }
}

Grails gorm does not provide direct access to views, but you can try HQL, or refer to Elegant ways to handle database views on hibernate entities? .
