This chapter details the core functionality exposed by the OpenAccess SDK SQL engine through the Application Programming Interface (API).
SQL Engine Parse Tree API describes additional functions that allow more detailed inspection of the query. Those functions are required for working in SQL pass-through mode, in table expression pushdown mode, and are otherwise optional, for when you need to retrieve additional data from the parse tree.
If you implement your IP for SQL pass-through mode, use only functions that are documented in
SQL Engine Parse Tree API .
