oracle.kv.exttab

## Class Preproc

- java.lang.Object
- - oracle.kv.exttab.Preproc

-     public class Preproc
      extends Object

  The Preproc utility is invoked by Oracle Database whenever a `SELECT` is performed on an External Table that has been associated with an Oracle NoSQL Database using the `Publish` utility. Preproc is responsible for reading data from the Oracle NoSQL Database using the user-specified query-restriction and formatting specifications. The formatted records are written to stdout where the Oracle Database reads them and imports them into the External Table.

  Preproc is invoked once for each `LOCATION` file in the External Table definition.

  Refer to the Admin Guide for more information on importing data from Oracle NoSQL Database into an Oracle External Table.
