public class FindAllPersistentMethod
extends AbstractStaticPersistentMethod

The "findAll" persistent static method allows searching for instances using either an example instance or an HQL query. Max results and offset parameters could be specified. A GrailsQueryException is thrown if the query is not a valid query for the domain class.

Syntax: DomainClass.findAll( query, params?) DomainClass.findAll( query, params?, max) DomainClass.findAll( query, params?, max, offset) DomainClass.findAll( query, params?, [max:10, offset:5])

Examples in Groovy: // retrieves all accounts def a = Account.findAll() // retrieve all accounts ordered by account number def a = Account.findAll("from Account as a order by a.number asc" ) // retrieve first 10 accounts ordered by account number def a = Account.findAll("from Account as a order by a.number asc",10 ) // retrieve first 10 accounts ordered by account number started from 5th account def a = Account.findAll("from Account as a order by a.number asc",10,5 ) // retrieve first 10 accounts ordered by account number started from 5th account def a = Account.findAll("from Account as a order by a.number asc",[max:10,offset:5] ) // with query parameters def a = Account.find("from Account as a where a.number = ? and a.branch = ?", [38479, "London"]) // with query named parameters def a = Account.find("from Account as a where a.number = :number and a.branch = :branch", [number:38479, branch:"London"]) // with query named parameters and max results and offset def a = Account.find("from Account as a where a.number = :number and a.branch = :branch", [number:38479, branch:"London"], 10, 5 ) // with query named parameters and max results and offset map def a = Account.find("from Account as a where a.number = :number and a.branch = :branch", [number:38479, branch:"London"], [max:10, offset:5] ) // query by example def a = new Account() a.number = 495749357 def a = Account.find(a)
