// --- TUTORIAL FOR SELECTING DATA USING ULTIMATE MYSQL ---

// Let's walk through the basics on how to query the database.
|
|
// Remember that you can execute a query that does not contain
|
|
// returned results, but in this example will use a SQL SELECT
|
|
// query to demonstrate showing results. You must have a basic
|
|
// working knowledge of SQL in order to use this class.
