public class DataSet extends Sql
def db = // an instance of groovy.sql.Sql
def sql = '''select * from Person
where (purchaseCount > ? and birthMonth = ?)

order by firstName DESC, age'''
def params = [10, "January", "Zulu", "Alpha", 99, 5, "Bert"]
def sortedPeopleOfInterest = db.rows(sql, params)
You can write code like this:
def person = new DataSet(db, 'Person') // or db.dataSet('Person'), or db.dataSet(Person)
def janFrequentBuyers = person.findAll { it.purchaseCount > 10 && it.lastName == "January" }
def sortedPeopleOfInterest = janFrequentBuyers.
findAll{ it.lastName < 'Zulu' || it.lastName > 'Alpha' }.
findAll{ it.age < 99 }.
findAll{ it.age > 5 }.
sort{ it.firstName }.reverse().
findAll{ it.firstName != 'Bert' }.
sort{ it.age }
