Here are some of the most common WordPress SQL user administration scripts that I run.
Backup! Backup! Backup!
First and foremost, before manipulating the database, ALWAYS back it up!
I am going to assume that you have access via a WordPress SQL Plugin or phpMyAdmin.
Remember, if you are like me and change the prefix, be sure to change the wp_ prefixes below to whatever your prefix is. I have added myprefix_ to help demonstrate where this change would be.

What does SQL stand for? (Yes I am in trouble & know nothing) Ha, Ha, Ha……..a chance to learn!!!!! I hired a person to do my site & it has never worked right, never finished…..Just kept trying to Jam me………..I have learned alot……..but sometimes I make it worse when I try to fix the broken links and things that dont work. 🙁
SQL means Structured Query Language. In other words, the programming that fetches the information from a database. In WordPress all your information sits in a database and WordPress is simply the GUI (Graphical User Interface) that helps you interact and properly store that information in the database while also displaying the information to the external user in a neat way (the PHP side of things). PHP means Personal Home Page and is server-side scripting. Simply, it is what the server serves the browser to display. JavaScript, in web development, is primarily client-side scripting, which means that it is programming that doesn’t run until the browser reads it (though there are JavaScript implementations than can run server-side.).
