Class OQLQuery

java.lang.Object

de.ipcon.db.oql.OQLQuery

public class OQLQuery
extends java.lang.Object

The main entry point for the OQL translator. The translator has a memory sensitive cache, so the static compile method might issue cached SQLQuery objects.
Usage:

 SQLQuery sq = OQLQuery.compile( schema, "select a from BO a", args );
