A basic guide to triggers in SQL and how they work.
*Note - In this video I referenced the table "Customers" twice. In real world applications this is redundant, to make it useful you can change the output (where "Customers" is referenced in the trigger statement) to another table provided that the information you provide aligns with the columns in that table. Then, when you try and insert values into Customers, it will trigger an entry into the new table.
