All Implemented Interfaces:

Query

Direct Known Subclasses:

BaseSelectQueryImpl, DataDefinitionQueryImpl, PassthroughQueryImpl, UnionQueryImpl, UpdateQueryImpl

public abstract class QueryImpl
extends Object
implements Query

Base class for classes which encapsulate information about an Access query. The toSQLString() method can be used to convert this object into the actual SQL string which this query data represents.
