database_changelog.txt

Any time you make a change to the schema files, remember to increment the database schema version. Generally increment the minor number, major should be reserved for significant changes to the schema. Both values go up to 255.

Make sure to also update `DB_MAJOR_VERSION` and `DB_MINOR_VERSION`, which can be found in `code/__DEFINES/subsystem.dm`.

The latest database version is 5.21; The query to update the schema revision table is:

INSERT INTO `schema_revision` (`major`, `minor`) VALUES (5, 22);
or
INSERT INTO `SS13_schema_revision` (`major`, `minor`) VALUES (5, 22);

In any query remember to add a prefix to the table names if you use one.

See the file 'feedback_conversion_2017-11-12.py' for instructions on how to use the script.

A new json feedback table can be created with:
CREATE TABLE `feedback` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `datetime` datetime NOT NULL,
  `round_id` int(11) unsigned NOT NULL,
  `key_name` varchar(32) NOT NULL,

----------------------------------------------------

Version 3.3, 25 August 2017, by Jordie0608

Modified tables 'connection_log', 'legacy_population', 'library', 'messages' and 'player' to add additional 'round_id' tracking in various forms and 'server_ip' and 'server_port' to the table 'messages'.

----------------------------------------------------

Version 3.0, 28 June 2017, by oranges
Added schema_revision to store the current db revision, why start at 3.0?

Created table `round` to replace tracking of the datapoints 'round_start', 'round_end', 'server_ip', 'game_mode', 'round_end_results', 'end_error', 'end_proper', 'emergency_shuttle', 'map_name' and 'station_renames' in the `feedback` table.
Once created this table is populated with rows from the `feedback` table.

Created table 'messages' to supersede the 'notes', 'memos', and 'watchlist' tables; they must be collated into this new table

To create this new table run the following command:

CREATE  TABLE `messages` (`id` INT(11) NOT NULL AUTO_INCREMENT , `type` VARCHAR(32) NOT NULL , `targetckey` VARCHAR(32) NOT NULL , `adminckey` VARCHAR(32) NOT NULL , `text` TEXT NOT NULL , `timestamp` DATETIME NOT NULL , `server` VARCHAR(32) NULL , `secret` TINYINT(1) NULL DEFAULT 1 , `lasteditor` VARCHAR(32) NULL , `edits` TEXT NULL , PRIMARY KEY (`id`) )

To copy the contents of the 'notes', 'memos', and 'watchlist' tables to this new table run the following commands:

INSERT INTO `messages`
(`id`,`type`,`targetckey`,`adminckey`,`text`,`timestamp`,`server`,`secret`,`lasteditor`,`edits`) SELECT `id`, "note", `ckey`, `adminckey`, `notetext`, `timestamp`, `server`, `secret`, `last_editor`, `edits` FROM `notes`

INSERT INTO `messages`
(`type`,`targetckey`,`adminckey`,`text`,`timestamp`,`lasteditor`,`edits`) SELECT "memo", `ckey`, `ckey`, `memotext`, `timestamp`, `last_editor`, `edits` FROM `memo`

INSERT INTO `messages`
(`type`,`targetckey`,`adminckey`,`text`,`timestamp`,`lasteditor`,`edits`) SELECT "watchlist entry", `ckey`, `adminckey`, `reason`, `timestamp`, `last_editor`, `edits` FROM `watch`

It's not necessary to delete the 'notes', 'memos', and 'watchlist' tables but they will no longer be used.

Removed erro_ from table names. dbconfig.txt has a option allowing you to change the prefix used in code, defaults to "erro_" if left out for legacy reasons.

If you are creating a new database and want to change the prefix, simply find and replace SS13_ to what ever you want (including nothing) and set the prefix value

Two schema files are now included, one with prefixes and one without.

If you have an existing database, and you want to rid your database of erros, you will have to rename all of the tables. A bit sql is included to do just that in errofreedatabase.sql Feel free to find and replace the prefix to what ever you want (or nothing)

The column 'deleted' was added to the erro_library table. If set to anything other than null, the book is interpreted as deleted.

To update your database, execute the following code in phpmyadmin, mysql workbench or whatever program you use:

ALTER TABLE erro_library ADD COLUMN deleted TINYINT(1) NULL DEFAULT NULL  AFTER datetime;

If you want to 'soft delete' a book (meaning it remains in the library, but isn't viewable by players), set the value in the 'deleted' column for the row to 1. To undelete, set it back to null. If you're making an admin tool to work with this, execute the following SQL statement to soft-delete the book with id someid:

UPDATE erro_library SET deleted = 1 WHERE id = someid

(Replace someid with the id of the book you want to soft delete.)
