Aug 6 12:24:24 testserver mysqld: 150806 12:24:24 [Note] /usr/libexec/mysqld (mysqld 10.0.20-MariaDB) starting as process 115096 ... why is this now stdout instead mysql logs? on systemd based distributions that spits now to the global syslog and finally on machines restarting 2 instances every hour for backup reasons it annoys until 10.0.19 or 10.0.20 that was not this way

[Maria-discuss] Virtual CHECK constraint using Virtual columns
by Peter Laursen 16 Oct '16

16 Oct '16

As described in this Blog http://mablomy.blogspot.dk/2016/04/check-constraint-for-mysql-not-null-on.h…. A very nice hack/trick IMO. However it is not working with MariaDB as VC's cannot be declared NOT NULL. What prevents that? -- Peter -- Webyog

[Maria-discuss] Bls: ask tool mariadb auto update latest for windows
by Irwanto 21 May '16

21 May '16

nice share mr. chris Pada Minggu, 22 Mei 2016 1:30, Chris Calender <chris.calender(a)mariadb.com> menulis: Hello, I have a custom .bat script I use on Windows which I use to upgrade both MariaDB and MySQL instances. It's not a supported 'tool' by any means, but works great for me in my Windows environment. You'll see 9 variables at the beginning which you will need to set for your environment, like basedir, datadir, config file, user, pass, port, service name, the download link, and download directory. I've attached it as a .txt file. Just edit those 9 variables, rename it to upgrade.bat, and invoke it from the command line: C:/location/of/file> upgrade.bat Once you have it set up for you instance, then future upgrades really only require you changing your download link. Beware I have all of the gnuwin32 utils, which this script uses, so you would either need those (e.g., wget, cp, mv, mkdir, unzip), or you would need to convert those commands to their native Windows equivalents. I also mention any caveats at the top of the file. In a nutshell, it downloads and unzips the package you specify. Then stops the service, copies out the old, replaces with the new, copies in existing datadir and config file, and then restarts the service. At the end, it runs mysql_upgrade, and then displays the new version number for your reference. Here is some sample output from an upgrade I just ran using it last night (from MariaDB 10.1.13 to 10.1.14). You can see at the end it took ~6 minutes, most of which was the download and extraction: ... inflating: C:\mysql/ma inflating: C:\mysql/ma +-----------------+ | version() | +-----------------+ | 10.1.13-MariaDB | +-----------------+ net stop "maria101" The maria101 service is stopping.

Please answer it at http://mariadb.com/kb/en/how-to-create-fake-data-inside-mariadb-sql-databas… as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hello World, I am trying to create some TEST DATA, meaning fake date for playing around with MariaDB tables and databases. I need to create some fake random data using SQL RDBMS. So, why not use Mockaroo.com , but on that website I can only do 1000 rows at one time. Which is extremely time consuming. How can I create random fake data. Tons of it. For example, Let us say I want 2 millions rows of random data with ID, NAME, ADDRESS, PHONE, EMAIL. I hope I am making sense. Any help is greatly appreciated!!!!! Thanks __________________ __________________ Linux Newbie - Information is Power! Download Linux @ http://www.fedora.redhat.com/ May the Linux force be with you!
