You are on the backup site for Chessvariants.com. Any posts, moves, or other changes you make here will not be permanent, because the pages and database from the main site will be backed up here every midnight EST. Additionally, things may not be working right, because this site is also a testbed for newer system software. So, if you are not here to test, develop, or merely read this site, you may want to change .org to .com in the navigation bar and go to the main site.

MySQL

This script queried the GameLogs table with the following prepared query:

SELECT * FROM GameLogs WHERE Priority = 1 AND (Opponent = '' OR Opponent IS NULL) AND (Privacy = :privacy OR Opponent = '' OR Opponent IS NULL) ORDER BY Lastmod DESC

To avoid SQL injection, most of the values are passed separately. The values in the query are determined by the values in your URL's query string or by what is entered into the form at top. When you leave a field blank, it normally means that it will leave that field out of the query, not that it will search for an empty value. Here is a recreation of what the SQL query would look like with the placeholders replaced by the values:

SELECT * FROM GameLogs WHERE Priority = 1 AND (Opponent = '' OR Opponent IS NULL) AND (Privacy = 0 OR Opponent = '' OR Opponent IS NULL) ORDER BY Lastmod DESC

The underlying MySQL is handled by MariaDB. A few fields give you multiple options for how to use them. You can search for an exact string match, an exact non-match, a LIKE match, which allows the use of a few wildcards, and a REGEXP match, which allows for very complicated pattern matching. Since these may slow down the search, they should be avoided unless you have a special need for them.

Filtering by Userid

If you enter a userid, it will list only those games in which that id identifies one of the players. Under the Next Move for column, for each game in which it is that user's turn to move, it will include a link for him to go to the PBM and make his next move. If a given user is playing any games that are not open to public view, he will need to enter his password to view these games on this page. If all your games are publicly viewable, then you don't need to include your password on this page.

How to Delete a Log

To get links for deleting logs, you must first enter a userid. To delete a log, you must be one of the players listed in the log. When you click on the link to delete a log, you will be asked for your password. Enter it and click on the Delete button. If your userid matches one of the players, and if your password is correct, the log will be deleted.
