I am new to Oracle Programming and trying to getting started with OCCI.
On Programmer's guide it indicates there are some demo available in
$ORACLE_HOME/rdbms/demo but I cannot find them.
I am using Oracle Database 18c Express Edition for Windows x64 and
followed the video tutorial for installing the product. Everything was
installed correctly I assume.
Can someone help?
XE is a slightly simplified install. For the EE edition the examples are in the Examples zip https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle18c-windows-180000-5066774.html
I don't have a solution for XE users.
Regardless of availability, in general you should consider calling OCI (not OCCI) from C++ since this is more fully featured and there are more examples out there. There are even wrapper libraries like https://oracle.github.io/odpi/ and OCILIB.
