    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)`
