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.
To truncate is to shorten by cutting off. In computer terms, when information is truncated, it is ended abruptly at a certain spot. For example, if a program truncates a field containing the value of pi (3.14159265...) at four decimal places, the field would show 3.1415 as an answer. This is different from rounding, which would result in the answer of 3.1416.
