* NAME
|
|
* plsqlarray.js
|
|
*
|
|
* DESCRIPTION
|
|
* Examples of binding PL/SQL "INDEX BY" tables. Beach names and
|
|
* water depths are passed into the first PL/SQL procedure which
|
|
* inserts them into a table. The second PL/SQL procedure queries
|
|
* that table and returns the values. The third procedure accepts
|
|
* arrays, and returns the values sorted by the beach name.
|
|
*
|
|
* Use demo.sql to create the required tables and package.
|
|
*
|
|
* This example requires node-oracledb 1.6 or later.
|
|
*
|
|
* This example uses Node 8's async/await syntax.
