Package de.tsl2.nano.persistence

Class SQLQuery

java.lang.Object

de.tsl2.nano.persistence.SQLQuery

All Implemented Interfaces:

de.tsl2.nano.core.execution.IRunnable<Object,String>

public class SQLQuery
extends Object
implements de.tsl2.nano.core.execution.IRunnable<Object,String>

provides some convenience for a persistence with an entitymanager with native queries and executions. In a JTA context you have to give a sessioncontext.

NOTE: method get(Class, String, Object...) works not with native query! Use select(String, Object...) instead.
