I don''t understand why you accept projects of something you don''t know, I understand that these days you have a lot more of companies out there, but if you don''t know something, then the customer will end up with a bad application and will have to pay more money to someone else to fix it, also hoping that some strangers will teach you is a bad approach.
You can start by reading the database help, SQL Server includes a very extensive and detailed help, it''s called "Books online", you can install it from the CD you used to install the software
If you still have doubts, Google is your friend, you will find hundreds of examples and explanations.
If you get stuck with your code, then you can come here and ask a specific question, post your code with the error and I assure you many will be more than happy to help you.

Good luck
