A wrapper for a JDBC batch operation. It has two modes:


Execute several queries without bind values
create.batch(query1,
             query2,
             query3)
      .execute();

Execute one query several times with bind values
create.batch(query)
      .bind(valueA1, valueA2)
      .bind(valueB1, valueB2)
      .execute();
