Can't send messages to the mailing list
Hello, I was subscribed for a long time to MySQL general mailing list but now I see that I can't send messages to the list because they are rejected, and in the error mail message that returns, I saw that it says something about SPAM. I didn't send spam mails to the list or to somewhere else but I have also seen that I couldn't even subscribe with another email address to the list because the subscription email is also rejected. If somebody knows, please tell me what can I do to be able to subscribe to the mailing list and send messages to it again. I was subscribed with the email orasn...@gmail.com. Thank you and sorry for offtopicness. -- Octavian -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
Re: Getting single results per (left) record with INNER JOIN
Hi Nigel, all !

Re: InnoDB - CREATE INDEX - Locks table for too long
Hi, I am using your procedure on MyISAM tables now and works but RENAME does not work with locked tables, (anyway it is already an atomic operation) =BARON Try something like this: create table new_table like old_table; alter table new_table add key(.); insert into new_table select * from old_table where primary_key between ? and ?; Repeat the last statement until nearly finished, then: lock tables new_table write, old_table write; insert into new_table select * from old_table where primary_key ?; rename table old_table backup, new_table old_table; unlock tables; so the above procedure fails unless I swap like this: - ... ... unlock tables; rename table old_table backup, new_table old_table; - The problem is of course that it is no more atomic. I also thought of SELECT for UPDATE that locks the records but does not prevent from inserting new ones, any suggestions? Thanks Clauido
Re: what will happen if the disk is full when mysql flush binlog to it
Hi Cui, On Sat, Mar 14, 2009 at 4:33 PM, Cui Shijun rancp...@gmail.com wrote: hi, What will happen if the disk is full when mysql flush binlog to it? If I use innodb engine(mysql-5.1.22) and turn on the binlog, is there any chance that mysql has data updated without binlog flushed? Will mysql return with fail when it fail on binlog? From the docs. Even with sync_binlog set to 1, there is still the chance of an inconsistency between the table content and binary log content in case of a crash. To resolve this, you should set --innodb_support_xa to 1. Although this option is related to the support of XA transactions in InnoDB, it also ensures that the binary log and InnoDB data files are synchronized. Having innodb_support_xa enabled on a replication master — or on any MySQL server where binary logging is in use — ensures that the binary log does not get out of sync compared to the table data. This is covered here http://dev.mysql.com/doc/refman/5.1/en/full-disk.html and here http://dev.mysql.com/doc/refman/5.1/en/binary-log.html Cheers, Ewen Thank you. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=ewen.fort...@gmail.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
MySQL 5.1 Rolling back a transaction containing Create Alter Drop table statements
Hi, Is there any way to rollback a transaction in MySQL 5.1 that contains Create, Alter, Drop, table statements. i.e. is there any way to turn off the feature: Statements That Cause an Implicit Commit or even remove some of the default statements that cause a commit. I tried using the TEMPORARY KEYWORD. It is not exactly what I want. Moreover, the ALTER syntax does not accept a TEMPORARY Keyword, and ALTER a temporary table causes an explicit commit. Any thoughts on this issue, -- Hatem Nassrat -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Migrating all MySQL from Netware to Suse
Hi! Trying to migrate from Netware to Suse (SLES 10 sp 1 NOWS SBE 2). I already changed the my.cnf file: 1.added a datadir=/MySQL/data line 2.removed the comments from all INNOdb lines The tables on the Netware files are not big On the SLES server I already see a mysql folder containing tables and an ibdata1 file In the old Netware DB there are also ibdata and ib_logfile. I did a mysqldump --single-transaction --quick -uroot -p --all-databases destination_file_name command on the Netware server. Does it include the ibdata* and ib_logfile*? What is the import command for the above mysqldump?

Re: Ever-shrinking disk space after repeated DB restores
OK, I found the answer. The binary log files were filling up (/usr/ local/mysql/data on OS X/mysql-bin.x).

W2008 Server Issues?
1. Any issues running MySQL Ver. X on Windows 2008 Server? 2. Running a query to list all records of about 2600 records is very slow and gets an error of Extremely High Work Load, Each record does contain 1 LONGBLOB containing small voice recording. We are using the SQL Query Browser and running the same query and same database on a 2000 server 1 gig less memory runs the query in about 15 seconds with no issues. Is this an issue with MySQL or the 2008 server?

You'd likely get much more predictable performance if you re-engineer your tables so that the BLOB is in a separate table from the main entity, with a FK from there. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Can't create table
Hello, I've tried to create these 4 test tables, but when I try to create the last one, MySQL gives the following error: ERROR 1005 (HY000) at line 20: Can't create table '.\z\favorite_link.frm' (errno : 150) It seems that the foreign keys are not created well in the fourth table, and I don't know why. Does anyone have any idea?
