* NAME
|
|
* raw1.js
|
|
*
|
|
* DESCRIPTION
|
|
* Shows using a Buffer to insert and select a RAW.
|
|
* Use demo.sql to create the dependencies or do:
|
|
*
|
|
* DROP TABLE myraw;
|
|
* CREATE TABLE myraw (r RAW(64));
|
|
*
|
|
* This example requires node-oracledb 1.2 or later.
|
|
*
|
|
* This example uses Node 8's async/await syntax.
