public class QueryProcessor
extends TemplateMetaData

Perform an assembled SQL query depending on its strategy

The strategy depends on whether the query contains elements which path depends on the context (e.g. a composition).

• If a query contains path expression that need to be resolved, the query process consists in evaluating the path for each composition (iteration)
• If the query contains only static fields (columns), a single query execution is done.
