@prabhjyotsingh Thank you for great improvement!
I tested this with mysql and all features are working well except one.
In following case, database connection would be closed and user should `use
db` command again.
so I think it needs something for managing connection state.
1. use db
2. execute right query.
3. execute fail query.
4. execute right query : then db connection would be closed.
What do you think?
