public class FindPersistentMethod
- extends AbstractStaticPersistentMethod
The "find" persistent static method allows searching for instances using
either an example instance or an HQL query. This method returns the first
result of the query. A GrailsQueryException is thrown if the query is not a
valid query for the domain class.
Examples in Groovy:
// retrieve the first account ordered by account number
def a = Account.find("from Account as a order by a.number asc" )
// 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"])
// query by example
def a = new Account()
a.number = 495749357
def a = Account.find(a)
