Sabagh: Or fix behavour of ctrl-w
Fullen: Boleware: yep, xy. I have a query. INSERT INTO b a_id SELECT a.id FROM a LEFT JOIN b ON a.id = b.a_id WHERE b.a_id IS NULL;
Oclair: Boleware: when i run this query from 2 clients at same time, coult table b have duplicates?
Baldini: So could scenarion: “1 Client 1 do select; 2 Client 2 do select; 3 Client 1 do insert 4 Client 2 do insert” be possible?
Sabagh: Http://dev.mysql.com/doc/refman/5.6/en/mysql-tips.html # finally!
Beneke: Geter: it probably is, try it and see
Asebedo: For answer my querstion i must know how mysql works under the huge.
Sabagh: I’m going back to the old client, this editline is killing me
Alexandropoul: I already built mysql from sources and play with eclipse/gdb debugger with it.
Hosler: But it is diffucult to understant how it works after a connections handling =.
Sabagh: Geter: if you do query to a temp table, then do insert to avoid dupes?
Lucien: Sabagh: to avoid duplicates i have unique index in table b;
Sabagh: OK, so just insert ignore from temp table
Sabagh: How do I point cmake at my copy of readline?
Gerveler: Whether to use the readline library bundled with the distribution.
Helmich: Maybe you could just replace / resymlink new readline instead of bundled? =
Sittman: Sabagh: currently i do INSERT INTO x SELECT FOR UPDATE. It workds
Altvater: But i dont want to lock table A.
Glory: INSERT IGNORE may help. I try.
Sabagh: Geter: that’s 5.5, I want 5.6
Waner: You could see to cmake files of 5.5 ti understand how do it in 5.6 with hands =
Adelmund: Mysql tells me “column ‘nb’ in field list is ambiguous” , this column being in a “on duplicate key update” statement , I struggle with these kind of error very often in a “on duplicate” statement, can someone explain me what’s wrong in this query : http://pastebin.com/HRPJRpmF
Sabagh: JesusTheHun: prefix the column name with the table name at a guess
Oropeza: Sabagh: the obvious guess 😀
Omura: Already done in 1st post
Sabagh: The query you pasted doesn’t prefix the column
Burgener: Ok I tried an alias, receiving an error
Sabagh: N DUPLICATE KEY UPDATE nb = nb + VALUESnb;
Wesch: P***ing the full name works
Brough: I don’t understand why is that
Sabagh: Column ‘nb’ in field list is ambiguous
Beske: I mean, VALUESX being the column value
Brea: It’s not ambiguous at all
Fitchett: There is only one possibility
Calcaterra: Can’t come from the select statement because it would be using VALUES
Closter: Can’t come from another table because it’s not allowed
Rodriguez: JesusTheHun: ambiguous means that it exists in 2 tables
Stefl: The fact you are joining 3 tables makes it extremely likely there is some duplicate nb that exists. we don’t have your schema to say why
Diggs: Just specify which one you want
Sutera: Xemdetia: you can’t pick a column that is not returned by the select statement can you ?
Furutani: Xemdetia, hey you alright ? I specified ssl-cipher in mysqld config file, and it worked right away =
Naone: Wrksx, yeah I ran into that same problem myself
Blasz: JesusTheHun, why can’t you?
Oshey: JesusTheHun, SELECT host FROM mysql.user WHERE User=’xemdetia’; works perfectly fine
