* 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.
* Use demo.sql to create the required schema.
