(Quick Reference) ## namedQueries namedQueries are deprecated. Use where queries instead. ### Purpose The `namedQueries` static property defines named queries. Named queries support the criteria builder syntax. See the section on the Criteria Builder in the user guide for more information. ### Examples
    class Publication {

       String title
       String author
       Date datePublished
       Integer numberOfPages

       static namedQueries = {
           recentPublications {
               def now = new Date()
               gt 'datePublished', now - 365
           }

           oldPublicationsLargerThan { pageCount ->
               def now = new Date()
               lt 'datePublished', now - 365
               gt 'numberOfPages', pageCount
           }

           publicationsWithBookInTitle {
               like 'title', '%Book%'
           }

           recentPublicationsWithBookInTitle {
               // calls to other named queries...
               recentPublications()
               publicationsWithBookInTitle()
          }
       }
    }
    // get all recent publications...
    def recentPubs = Publication.recentPublications.list()

    // get up to 10 recent publications, skip the first 5...
    def recentPubs = Publication.recentPublications.list(max: 10, offset: 5)

    // get a single recent publication
    def recentPub = Publication.recentPublications.get()

    // get the number of recent publications...
    def numberOfRecentPubs = Publication.recentPublications.count()

    // get a recent publication with a specific id...
    def pub = Publication.recentPublications.get(42)

    // get all recent publications where title = 'Some Title'
    def pubs = Publication.recentPublications.findAllWhere(title: 'Some Title')

    // get a recent publication where title = 'Some Title'
    def pub = Publication.recentPublications.findWhere(title: 'Some Title')

    // dynamic finders are supported
    def pubs = Publication.recentPublications.findAllByTitle('Some Title')

    // get all old publications with more than 350 pages
    def pubs = Publication.oldPublicationsLargerThan(350).list()

    // get all old publications with more than 350 pages
    // and the word 'Grails' in the title
    def pubs = Publication.oldPublicationsLargerThan(350).findAllByTitleLike('%Grails%')

    // get all recent publications with 'Book' in their title
    def pubs = Publication.recentPublicationsWithBookInTitle().list()
The `list` method on named queries supports the same attributes as the static `list` method added to domain classes (sort, order, ignoreCase, fetch etc…​). See the list docs for details.
| Note that calling something like `Publication.recentPublications.get(42)` is not the same as calling something like `Publication.get(42)`. The former will only return a `Publication` if the `Publication` with id 42 meets all the criteria defined in the `recentPublications` named query.
Named criteria support `listDistinct()`:
    class PlantCategory {

        Set plants
        String name

        static hasMany = [plants: Plant]

        static namedQueries = {
            withPlantsInPatch {
                plants {
                    eq 'goesInPatch', true
                }
            }
        }
    }
    class Plant {
        boolean goesInPatch
        String name
    }
    PlantCategory.withPlantsInPatch.listDistinct()
Named criteria support additional criteria being supplied at invocation time in the form of a criteria closure:
    // get all recent publications with author names beginning with Tony or Phil...
    def books = Publication.recentPublications {
        or {
            like 'author', 'Tony%'
            like 'author', 'Phil%'
        }
    }

    // get the number of recent publications with
    // author names beginning with Tony or Phil...
    def numberOfBooks = Publication.recentPublications.count {
        or {
            like 'author', 'Tony%'
            like 'author', 'Phil%'
        }
    }
Named criteria may be chained together. When criteria are chained together, the query will be generated as if all of the chained criteria had been combined in a single criteria closure.
    // recent publications with 'Book' in the title
    def books = Publication.recentPublications.publicationsWithBookInTitle.list()

    // old publications with more than 500 pages and with 'Book' in the title
    def books = Publication.oldPublicationsLargerThan(500)
                           .publicationsWithBookInTitle
                           .list()
When a named query involves a domain class relationship and the relationship class defines a named query, that named query may be accessed directly as a method call. An example:
    class Author {

        static hasMany = [publications: Publication]

        static namedQueries = {
             authorsWithRecentPublications {
                 publications {
                     // invoking a named query defined in the Publication class...
                     recentPublications()
                 }
             }
        }
    }
    class Publication {

        Author author

        static namedQueries = {
            recentPublications {
                def now = new Date()
                gt 'datePublished', now - 10
            }
        }
    }
