Question

Assume a domain class called User. User class looks like this:

class User {
     List<String> values
}

The collection values contains strings like “http://example.com/x”, “http://google.com/y”, “http://google.com/z” and so on…

Let’s say we want to build a query which gets all the users that have specific string in the collection values (e.g. “google.com”). Something like this:

def criteria = User.createCriteria()
def results = criteria.listDistinct () {
  and {
    user.values.each {  like('someField', '%${it}%') }
  }
}

Any ideas?

Answer 1

I have found the answer by experimentation. The solution is:

def criteria = User.createCriteria()
def results = criteria.listDistinct () {
  and {
    user.values.each {  like('someField', '%'+it+'%') }
  }
}
