The PS4 can upload screenshots from both within and outside of games. To capture and upload a screenshot, press the Share button on the DualShock 4. This takes a snapshot and opens a menu.
DROP TABLE goes further than a TRUNCATE in that it actually removes the table from the database completely. This includes removing all associated objects, such as indexes and constraints. If you dropped a table, not only would you remove all the data, but the structure as well.
DELETE is a logged operation on a per row basis. This means. that the deletion of each row gets logged and physically deleted. You can DELETE any row that will not violate a constraint, while leaving the foreign key or any other contraint in place. TRUNCATE is also a logged operation, but in a different way.
