* NAME
* plsqlproc.js
*
* DESCRIPTION
* Show calling a PL/SQL procedure and binding parameters in various ways
* Use demo.sql to create the required procedure or do:
*
* CREATE OR REPLACE PROCEDURE testproc (p_in IN VARCHAR2, p_inout IN OUT VARCHAR2, p_out OUT NUMBER)
* AS
* BEGIN
* p_inout := p_in || p_inout;
* p_out := 101;
* END;
* /
*
* This example uses Node 8's async/await syntax.
*
