Hi! MySQL 5.6 returns a warning for wrong datatypes, with any SQL_MODE: mysql> CREATE TABLE t (c TIMESTAMP) ENGINE=InnoDB; Query OK, 0 rows affected (0,31 sec) mysql> SELECT c FROM t WHERE c = 1; Empty set, 1 warning (0,00 sec) Warning (Code 1292): Incorrect datetime value: '1' for column 'c' at row 1 Will this be done in MariaDB 10 too? Currently, no warning is issued. Federico

[Maria-discuss] INFORMATION_SCHEMA.PROCESSLIST values of PROGRESS, STAGE and STAGE_MAX
by Jean Weisbuch 11 Dec '13

11 Dec '13

Hello, Lately, i did modify mytop (https://mariadb.atlassian.net/browse/MDEV-4476) to use INFORMATION_SCHEMA.PROCESSLIST instead of SHOW PROCESSLIST (when available) to gather running processes informations as it's more flexible and has more informations but the value of the PROGRESS column on both is different, so i wondered if the PROGRESS value on SHOW PROCESSLIST was using a simple formula like this one or something more complex : (STAGE-1)/MAX_STAGE + {decimal progress on the actual stage}/MAX_STAGE There seems to be a broken alinea about that on the KB page of the PROCESSLIST : https://mariadb.com/kb/en/show-processlist/ In any case, what would be the best way to go with mytop, add columns with the actual_stage/max_stage or only keep the progress of the actual stage or only the "total" progress using the formula previously shown? Putting an option and keystroke to show/hide these columns could be another solution as these values might be of use on only "rare" cases depending on the workload. Regards.

[Maria-discuss] Mroonga storage engine is merged into MariaDB 10.0
by kentoku 01 Dec '13

01 Dec '13

Hi! We just pushed Mroonga storage engine into "lp:~mroonga/maria/mroonga". Mroonga is a fulltext/geo search storage engine. Would you please bundle Mroonga into MariaDB? Mroonga's strong points are - High-speed updating with multiple thread searching. (lock-free model) - Support CJK languages. - Support wrapper mode. Wrapper mode works adding fulltext/geo index for other storage engines. Mroonga is tested on the following 64bit OS. Debian GNU/Linux squeeze Debian GNU/Linux wheezy Debian GNU/Linux jessie Debian GNU/Linux sid Ubuntu 10.04 LTS Lucid Lynx Ubuntu 12.04 Precise Pangolin Ubuntu 12.10 Quantal Quetzal Ubuntu 13.04 Raring Ringtail Ubuntu 13.10 Saucy Salamander CentOS 5 CentOS 6 Fedora 19 Mac OS X Windows 7 Mroonga documents (English & Japanease) are available on http://mroonga.org/docs/index.html Test command is the followings. The command calls mysql-test-run.plinternally. > ./storage/mroonga/test/run-sql-test.sh Thanks, Kentoku
