I am making a site and I would like to have something which allows users to login, create a account, and are able to go to a page where they can edit their information (ex: change password, where they live, etc.). I have MySQL and Microsoft SQL installed (I don't know which one is better)

I am not sure how to link the text boxes with the database so users can login or create an account. It would also be nice if somebody could tell me how to make an error messages appear if information is invalid.

I am good at programming but i am new to working with a database.

If anybody has a template with all this set up so I could build the site around the template that would be great.

Here are my columns:

Username
Password
Day_Birth
Month_Birth
Year_Birth
Email
First_Name
Last_Name
Country
City
State_Province
IP (im not sure how to retrieve the ip address)
Date_Created
ID
