add more examples

[chirag04]

examples for doing queries with where clause could be more than helpful.

I saw api documentation but that dint help much

[CraigLRussell]

To prioritize our work, could you tell us what examples are most important?

Thanks.

Hi Craig,

1. Connection pooling in the cluster.
2. queries with predicate where clause.
3. transactional queries
4. resultset with multiple rows
