Is it possible for a Grails Domain to have no 'id'?

Question

Is it possible to create a table that has no \'id\'? For example, this is my domain:

class SnbrActVector {

    int nid
    String term
    double weight

    st         


        

Answer 1

You probably need to specify that nid is your id column.

static mapping = {
    version false
    id generator: 'identity', column: 'nid'
}
