> Examine how to really get better performance for oracle statement batches.
> [Oracle JDBC
> doc|https://docs.oracle.com/cd/E11882_01/java.112/e16548/oraperf.htm#JJDBC28752]
> describes:
> {quote}The Oracle implementation of standard update batching does not
> implement true batching for generic statements and callable statements. Even
> though Oracle JDBC supports the use of standard batching for {{Statement}}
> and {{CallableStatement}} objects, you are unlikely to see performance
> improvement.
> {quote}
> I would look for connection properties to set, so it is handled anyway, or if
> not, then use:
> {code}
> begin
> query1;
> query2;
> query3;
> end;
> {code}
> to we will have only a single roundtrip for the db.
