This appendix describes files distributed with the database that demonstrate how LOBs are used in supported programmatic environments. This appendix contains these topics:
The following table lists PL/SQL demonstration files. These files are installed in $ORACLE_HOME/rdbms/demo/lobs/plsql/
. A driver program, lobdemo.sql
, that calls these files is found in the same directory.
