* NAME

|
* impres.js
|
|
*
|
|
* DESCRIPTION
|
|
* Shows PL/SQL 'Implict Results' returning multiple query results
|
|
* from PL/SQL code.
|
|
*
|
|
* This example requires node-oracledb 4.0 or later, Oracle Database
|
|
* 12c or later, and Oracle Client 12c libraries or later.
|
|
*
|
|
* This example uses Node 8's async/await syntax.
