SQL Engine parse tree methods for Java : Pass-through query processing
 

Pass-through query processing

When OpenAccess SDK is run in SQL pass-through mode, query processing is performed as follows:
*The OpenAccess SDK SQL engine performs the parsing of the query.
*The IP handles the execution of the query, including all joins, unions, etc.
An IP working in SQL pass-through mode must exclusively use the API calls that are documented in this chapter when called to execute a statement through the EXECUTE entry point (ipExecute method in your IP).
