Hiya Nobody! Lets just say you're creating a web app and working with a back-end language like PHP, and you're doing the pagination of your website. And your boss asked you to retrieve first 30 items(inclusive) from the database(lets consider mysql for this example). And This is what your code should look like:

$sql = "SELECT * FROM Orders LIMIT 30";

Now, she asks you to display the items range from 11 - 20(inclusive) from the database on the web page. Here comes the OFFSET clause to rescue. Here is how your code should look like:

$sql = "SELECT * FROM Orders LIMIT 10 OFFSET 10";

The above SQL query also says "return only 10 records, start on record 11 (OFFSET 10)". I hope it makes sense now. Good Luck! (:
