Редактирование: MySQL (раздел)

=== Filter columns ===

The problem is that when you are selecting something from the database in programs, you'll want as little data transfer as possible. So selecting all columns is rarely needed. Let's suppose we want a list of players and what their last admin rank was:

SELECT ckey, lastadminrank<br>
FROM ss13_player

Voila. Once you execute this, you will get a table, which has a list of all the players who played on your server. The returned table will contain two columns: Their ckey and the admin rank they held when they last connected.
