SQL Engine parse tree methods for Java

This section describes a special set of OpenAccess SDK API methods that your IP can call for the following purposes:

• Working in SQL pass-through mode.

  Note: An IP that works in SQL pass-through mode must use only the methods in this section.

• Performing table pushdown.

  Refer to About Table Expression Pushdown in the OpenAccess SDK Programmer's Guide for additional information on implementing table pushdown.

• Retrieving more information through the parse tree than is provided through the standard OpenAccess SDK SQL Engine core methods for Java.
