(Quick Reference)



Uses named arguments corresponding to domain class property names to execute a query returning the first matching result.


Given the domain class:

class Book {

   String title
   Date releaseDate
   String author

   static constraints = {
      releaseDate nullable: true

You can query in the form:

def book = Book.findWhere(author: "Stephen King", title: "The Stand")

boolean isReleased = Book.findWhere(author: "Stephen King",
                                    title: "The Stand",
                                    releaseDate: null) != null
