Error 1032 : Can't find Record in table
Hello,
I'm curently testing partitioning with mysql 5.1.11 on linux (.rpm from
mysql.com site).
Table Structure:
CREATE TABLE `adr-0` (
Adr varchar(255) COLLATE latin1_german1_ci NOT NULL DEFAULT '',
Qty int(10) NOT NULL,
PRIMARY KEY (Adr),
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_german1_ci
PARTITION BY KEY (Adr) PARTITIONS 10 ;
Now I'm inserting data:
insert into adr-0 values ('TestAdr','1') on duplicate key update qty =
qty +1;
This works fine until on duplicate key triggers. Then I receive the
error message:
1032: Can't find record in adr-0
When I'm doing the same on a non-partitioned table, everything work as
expected.
I haven't found any limitations of the partitioning in the manual, which
could be the reason.
Is this a bug or a feature ?
Thanks in advance for any help !

Problems connecting using -h hostname with new installation
Hello, I installed MySQL on a remote server and am having a problem. I am connected to it via SSH and I can do mysql -u root -h localhost just fine and connect. However, when I try to connect via mysql -u root -h web1.server.com, I get the following message: ERROR 1130 (0): Host '75.120.X.X' is not allowed to connect to this MySQL server Now the server's hostname is web1.server.com and it resolves to 75.120.X.X fine so I know it's not an issue with that. Does anyone have any clues why? I have a web1.server.com added in the mysq.user table so I know that's not the problem. If I add 75.120.X.X to the mysql.user table, I am able to connect via mysql -u root -h web1.server.com just fine. But why won't it work when web1.server.com is in the mysql.user table? Thanks for any help. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Replicating -- sort of 2 way
Before I go reading too deep into the documentation I would like to know if this is even possible or if it is just a bad idea. I have Server A with DB X, and server B with DB Y. I would like to set up Server A and B as both a replication master and slave. Where Server A would be the Master for DB X and the Slave for DB Y AND Server B would be the Master for DB Y and Slave for DB X. The reason I am doing this is just for keeping a backup.

Re: Can't get v5.0.22 to work;alternatives?
Hi, Earlier, I forgot to CCed the reply to the list and, accidentally, posted a blank reply instead. So, here is the copy of the reply that I sent to the original poster - in case, someone else has the same problem. Additionally, I have found that the MySQL ODBC driver installs best when you do it manually - that is, hand-copy files into the Windows System32 directory. In addition, as I have found, it complains that some MSVCR7.dll is missing. When I searched for the file on Google, the search engine led me to some DllFiles.com (or some similar webpage) where I got the file, downloaded the same to my computer and everything worked like a cinch! -- Good luck, Asif On 8/1/06, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I can't get MySQL v5.0 to work on my system.

Possible to use multiple conditions in SET/Declare?
Hi All,
I know that we can do stuffs like
declare @temp1 varchar(20), @temp2 varchar(20)
set @temp1 = A
set @temp2 = Z
select * from table where table.column = @temp1
I would like to do something like this.
set @temp1 = ('A','B','C')
select * from table where table.column IN @temp1
Is it possible?

Re: Error 1032 : Can't find Record in table
Detlev,
It is possible that mysql is interpreting adr-0 as a
arithmetic operation, why don't you try quoting the
table name to prevent mysql trying to interpret it as
anything...
insert into `adr-0` values ('TestAdr','1') on
duplicate key update qty =
qty +1;
regards,
Enrique.

Re: Replicating -- sort of 2 way
Chris, Replicating for the sake of backups is in general a bad idea, since once you delete/update a record, it will be automatically propagated to the slave server. Replication, should be used to provide better availabilty/load balancing but that would need to be setup as part of a bigger plan to provide higher availabilty to the service that you are providing. One thing that you could do, is to setup a replicating slave server, freeze the replication, perform backups (to tape/disks etc), then re-enable the replication activity, this way you provide a non-stop service without compromising your data availabilty. best regards, Enrique. --- Chris W [EMAIL PROTECTED] wrote: Before I go reading too deep into the documentation I would like to know if this is even possible or if it is just a bad idea.

The reason I am wanting to use it as a backup is because it is easy automatic and I don't have to do anything once it is set up. The backup would be in case of disk failure not data corruption. I would probably run local backups too. The replication I was planing on doing was going to be between 2 servers at 2 different locations, which would allow for the best backup in case of disaster that completely destroyed one location. -- Chris W KE5GIX Gift Giving Made Easy Get the gifts you want give the gifts they want One stop wish list for any gift, from anywhere, for any occasion! http://thewishzone.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I've tried this in the past. Replication on large, non-single-application database servers is hard. When you have over a thousand users on a single (very large) DB server the chances that one of them will trip one of the 'does not replicate correctly to slave and causes slave to stop dead in tracks' bugs is pretty high. We found (even with 4.1 series) that we were restarting or dealing with stopped replication on a daily basis. We stopped trying somewhere around 4.1.11 so things may have improved, but they may not have. For a single application or a limited set of applications it seems to work great and you can whittle out any cases where the app does something that doesn't replicate correctly somehow. With large numbers of apps/people using it we usually had to turn down or turn off the error checking on the slave so it wouldn't stop in it's tracks all the time. This of course caused the issue of you were never totally sure that what was on the slave was what was on the master. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
