Display MySQL Data in a Label - Vb.Net

I have some code here that connects to my Mysql database. It checks your username and password and if your login was successful and it retrieves the phone number under that account. How would the SQL Query look like for retrieving the phone number once connected? Then how would I be able to开发者_StackOverflow社区 display that phone number on a label?

Have a look at this tutorial, should cover most of what you would need to know about connecting to MySQL, executing queries and displaying results:
