16:57 domas ronsel: THANKS FOR BRINGING IN THIS MADNESS
16:57 djahandarie lol @ that first sentence… “Widenius will die”
16:57 domas heh
16:58 domas nooooeeeees, we need Monty
16:58 tanj maybe someone should add “no petitions” to the topic
16:58 domas even though he causes frustration and despair
16:58 CorticalStack (here we go)
16:58 ronsel whats going on with the monty?
16:58 domas he’s still a nice guy!
16:58 tanj and besides without him we wouldn’t be here today
16:58 Server agib (email@example.com) hat den Kanal betreten.
16:58 ronsel thats for sure!
16:59 ronsel this channel could have a strange name like postgres
16:59 domas tanj: yep, that would be so sad, we’d be in #postgresql
16:59 domas or some other.
16:59 domas firebird!
16:59 ronsel lol
16:59 tanj hey i’m in #postgresql also
16:59 VoVo64 #nosql
16:59 domas I’m there sometimes too
16:59 TodoInTX tanj: many people have contributed to getting us to where we are today.
16:59 domas they think I’m trolling though and want to ban me
17:00 domas and all I do is careful benchmarking
17:00 Isotopp i have a SELECT … FROM t WHERE (room_name_id, language_code ) IN ( ( 153701, “en”) ) yields in a Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation ‘=’
17:00 CorticalStack with perl pack and unpack functions you don’t really need rdbms anyway.
17:00 TodoInTX hehe
17:00 thumbs domas: to be fair, not knowing you, you could come out as a troll.
17:00 Isotopp but SELECT … FROM t WHERE `room_name_id`=153701 AND `language_code` = “en”; works just fine
17:00 tanj TodoInTX: I know. I’m just jumping on the monty bandwagon :=)
17:00 Isotopp is this a mysql tuple equivalency processing problem again?
17:01 domas isotopp: this is coerciveness issue
17:01 thumbs Isotopp: check the collation on both columns.
17:01 Server spetrunia (firstname.lastname@example.org) hat den Kanal betreten.
17:01 domas isotopp: but probably a bug too
17:01 Isotopp domas: language_code is a latin1 column, and i am on a SET NAMES utf8 connection
17:01 domas isotopp: probably coerciveness doesn’t work that well with IN(())
17:01 Isotopp domas: also, IN ( ( 153701, _latin1 “en”) ) works fine
17:02 domas it assumes that whole ((),(),()) set can have different charsets
17:02 tanj implicit cast in the 2nd case, prolly
17:02 Isotopp domas: but it is unclear to me why the WHERE … AND … works, whereas the IN (()) does not
17:02 domas isotopp: ^^^
17:02 domas my assumption
17:02 domas anyway, bug, file.

17:03 domas he can’t
17:03 domas nobody can

17:10 montywi and MySQL is GPL and anyone can use it, but not to promote another product

17:29 salle montywi: I do have my own company Salle LTD. Do you say I can certainly manage MySQL better than Oracle?
17:29 Therion montywi: MySQL without that engine does not usefully compete with Oracle
17:29 MLord montywi: if Oracle had killed InnoDB or revoked the license than MySQL would NOT compete in any real way
17:29 Therion montywi: Otherwise, you wouldn’t have spent the last however many years on Maria
17:29 fission6 oracle is going to own MySql
17:29 salle montywi: You know me and know I have no interest in killing it.
17:29 domas and falcon!
17:29 lng hi! is it possible to use foreign key constraint to delete data in child tables if parent row is deleted?
17:29 MLord montywi: so MySQL only supposedly competes with Oracle because they’ve let it. Ironic isn’t it?
17:29 Therion lng: yes
17:29 domas lng: cascade
17:30 fission6 SixThreeOh: show slave status; ?
17:30 lng thanx
17:30 domas damn, therion is still faster than me, after all these years of absence
17:30 SixThreeOh http://pastebin.com/d73930da1 < here

17:30 Therion domas: lol
17:30 fission6 anyone here use a shard approach with in mysql
17:30 domas fission6: a bit
17:30 lng the_XL: yea
17:30 tanj sharding
17:30 the_wench a technique used for horizontal scaling of databases. Read http://www.jurriaanpersyn.com/archives/2009/02/12/database-sharding-at-netlog-with-mysql-and-php/
17:30 xzilla fission6: sure
17:30 TodoInTX SixThreeOh: if that db doesn’t exist on the slave skip that query and move on.
17:30 Server guy (firstname.lastname@example.org) hat den Kanal betreten.
17:31 SixThreeOh how can I tell the slave to ignore it?
17:31 guy any ideas why this would cause SQL syntax error?
17:31 guy SELECT *, (SELECT COUNT(language) FROM hp_pages p1 WHERE p1.language = l1.id) AS active FROM hp_languages l1 ORDER BY active DESC AND l1.position;
17:31 SixThreeOh the table doesn’t exist on either.

17:31 thumbs guy: what is the error?
17:31 guy SQLSTATE: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘AND l1.position’
17:31 fission6 xzilla: are the tables across different db nodes or partitioned on a db?
17:31 domas syntax
17:31 the_wench DO NOT INVENT SYNTAX (well, unless you have commit rights). Just follow the syntax described in the manual. Thanks.
17:31 domas guy: ^^^
17:32 domas o dabar eik

17:33 xzilla fission6: i think i have done it both ways
17:33 xzilla fission6: but most recent was different db nodes
17:33 montywi MLord: No, MySQL competes with Oracle because we are in the same market. Oracle buying InnoDB didn’t change that (We had a contract for many years that allows us to continue to sell licenses)
17:33 Server ajm (firstname.lastname@example.org) hat den Kanal betreten.
17:33 nils_ montywi: with no way for Oracle to kill InnoDB?
17:33 fission6 you think heh? my question being from a mysql how do i make it transparent to developers to write queries and have them execute on the right db nodes within a sharded achetcture
17:33 MLord montywi: Our original license agreement ended AFTER they bought Innobase. You know that!

17:33 domas fission6: generally you don’t
17:34 xzilla fission6: you dont
17:34 domas fission6: but there’re some people who try to make it
17:34 montywi nils_: they could stop developing it yes; They would however have to fix bugs.
17:34 domas montywi: for how many years?
17:34 SixThreeOh tanj thanks.
17:34 MLord montywi: at the very least they could have let it idle or die, which they didn’t.
17:34 montywi If the would stopped developing it, then MySQL could have caused a fork
17:34 xzilla domas: well yes, you can do it how skype did it, but I dont think there is a way to do it in mysql (not with any level of complex app anyway)

17:35 MLord montywi: exactly! The only problem is that dual licensing couldn’t be used….

17:35 MLord montywi: it sounds like you’re arguing against yourself
17:35 montywi domas: you mean licenses? For 4 years, but they extended the contract after negotiations with us
17:35 xzilla montywi: istm that innodb has actually seen more development than any other table engine between the time oracle purchased it and now
17:35 montywi MLord: they used InnoDb to stop us from growing, and they where very successful with that
17:36 Leithal xzilla: that is true
17:36 montywi xzilla: no
17:36 Leithal balls
17:36 Therion montywi: We grew enormously after their purchase. You’re not even playing in reality, here.
17:36 xzilla montywi: mysql grew under Sun, how can you say they stopped you from growing?!?
17:36 MLord montywi: how so? that makes no sense
17:36 montywi All the new storage engines, PBXT, Calpoint, Infobright is doing much more
17:36 Therion No trolling here
17:36 domas Therion: did you hire xzillla?
17:36 Therion Take it somewhere else
17:36 MLord montywi: if you’re going by the… what do people call it… oh yeah, facts.
17:36 montywi xzilla: I meant before Sun
17:36 domas montywi: PBXT is not usable for disk-bound workloads, calpoint and infobright are not OLTP
17:37 TodoInTX montywi: a meteor could fall from the sky and kill me today, doesn’t mean that I have any proof that it will.
17:37 Therion domas: alas, no
17:37 Therion domas: do you want a job?!
17:37 MLord montywi: yeah, they’re doing much more… ok
17:37 montywi it still got more development done than InnoDB and it’s slowly getting there
