(Quick Reference) # findAll ## Purpose Finds all of domain class instances matching the specified query ## Examples

    // everything
    Book.findAll()// with a positional parameter
    Book.findAll("from Book as b where b.author=?", ['Dan Brown'])// 10 books from Dan Brown staring from 5th book ordered by release date
    Book.findAll("from Book as b where b.author=? order by b.releaseDate",
                 ['Dan Brown'], [max: 10, offset: 5])// examples with max/offset usage
    def query = "from Book as b where b.author='Dan Brown' order by b.releaseDate"// first 10 books
    Book.findAll(query, [max: 10])// 10 books starting from 5th
    Book.findAll(query, [max: 10, offset: 5])// examples with named parameters
    Book.findAll("from Book as b where b.author=:author",
                 [author: 'Dan Brown'])
    Book.findAll("from Book as b where b.author=:author",
                 [author: 'Dan Brown'], [max: 10, offset: 5])
    Book.findAll("from Book as b where b.author in (:authors)",
                 [authors: ['Dan Brown', 'Jack London']])// examples with tables join
    Book.findAll("from Book as b where not exists " +
                    "(from Borrow as br where br.book = b)")// query by example
    def example = new Book(author: "Dan Brown")
    Book.findAll(example)// Use where criteria (since Grails 2.0)
    def results = Person.findAll {
         lastName == "Simpson"
    }
    def results = Person.findAll(sort:"firstName") {
         lastName == "Simpson"
    }
## Description The `findAll` method allows querying with Hibernate's query language HQL and querying by example, returning all matching instances. Pagination can be controlled using the `max` and `offset` parameters:
    Book.findAll("from Book as b where b.author=:author",
                 [author: 'Dan Brown'], [max: 10, offset: 5])
The `findAll` method supports the 2nd level cache:
    Book.findAll("from Book as b where b.author=:author",
                 [author:'Dan Brown'], [max: 10, offset: 5, cache: true])
The basic syntax for the method is:
    Book.findAll()
    Book.findAll(String query)
    Book.findAll(String query, Collection positionalParams)
    Book.findAll(String query, Collection positionalParams, Map queryParams)
    Book.findAll(String query, Map namedParams)
    Book.findAll(String query, Map namedParams, Map queryParams)
    Book.findAll(Book example)
    Book.findAll(Closure whereCriteria)
    Book.findAll(Map queryParams, Closure whereCriteria)
If you have a join in your HQL, the method will return a `List` of `Array`s containing domain class instances. You may wish to use executeQuery in this case so you have more flexibility in specifying what gets returned. Parameters: `query` - An HQL query `positionalParams` - A `List` of parameters for a positional parametrized HQL query `namedParams` - A `Map` of named parameters a HQL query `queryParams` - A `Map` containing parameters 'max', and/or 'offset' and/or 'cache' `example` - An instance of the domain class for query by example `readOnly` - `true` if returned objects should not be automatically dirty-checked (simlar to `read()`) `fetchSize` - number of rows fetched by the underlying JDBC driver per round trip `flushMode` - Hibernate `FlushMode` override, defaults to `FlushMode.AUTO` `timeout` - query timeout in seconds | Quick Reference (hide)
