Please help me understand optimistic locking and Pessimistic locking
I read the documents about them but couldn't really understand them. Could any database guru here explain what they are in examples. Thanks a lot!

Rather than posting such an open ended question, why don't you post specific questions on what you don't understand?

Re: Please help me understand optimistic locking and Pessimistic locking
An optimist doesn't think that there's much need for locking so does so only occasionally. A pessimist thinks locking is always needed so does so all the time. 
All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.
