* NAME
* em_batcherrors.js
*
* DESCRIPTION
* Array DML example showing batchErrors behavior. Note, despite the
* autoCommit flag, no commit occurs because of data errors. However
* valid rows are part of a transaction that can be committed if
* desired.
* This example also uses Async/Await of Node 8.
* Use demo.sql to create the required schema.
*
* This example requires node-oracledb 2.2 or later.
*
* This example uses Node 8's async/await syntax.
*
