I am getting following error:
Got temporary error 233 'Out of operation records in transaction coordinator (increase MaxNoOfConcurrentOperations)' from NDBCLUSTER
While inserting data into ndb table.
Can anyone explain more about this error. Also in my config.ini I dont have this parameter set. Is there any way I can see the default value of this variable. as I canot see this variable when I am using commmand SHOW VARIABLES.
To set this variable do I also need to change the MaxMaxNoOfConcurrentTransactions and MaxNoOfLocalOperations.
The default value for MaxNoOfConcurrentOperations is 32768 but you can increase this value by editing your ndb_mgm config i.e. /etc/mysql/ndb_mgmd.cnf
and adding something like
MaxNoOfConcurrentOperations=100000
When updaing the MaxNoOfConcurrentOperations value you should also update MaxNoOfLocalOperations. The rule of thumb is to make MaxNoOfLocalOperations 10% larger than MaxNoOfConcurrentOperations so you would have.
MaxNoOfConcurrentOperations=100000
MaxNoOfLocalOperations=110000

I have a big problem when I want to make a view.
CREATE VIEW AnneeBillet (ANNEE_BILLETS, CHIFFRES)
AS SELECT YEAR(FIN_RESERVATION), sum(TYPE.PRIX*NOMBRE)
FROM TYPE, BILLET
where TYPE.TYPE = BILLET.TYPE;
I have this error :
In aggregated query without GROUP BY, expression #1 of SELECT list
contains nonaggregated column 'parc.BILLET.FIN_RESERVATION'; this is
incompatible with sql_mode=only_full_group_by
I have already tried many solutions like putting
SET GLOBAL sql_mode=(SELECT REPLACE(##sql_mode,'ONLY_FULL_GROUP_BY',''));
But I'm with a docker container and I've seen that I had to modify directly the configuration file to have what I want.
Then, I found this post on stackoverflow but I can't do
--sql_mode=(SELECT REPLACE(##sql_mode,'ONLY_FULL_GROUP_BY',''))
in my docker-compose because I have an error like this :
mysql_1 | 2021-04-27T07:59:53.283400Z 0 [ERROR] [MY-000077]
[Server] /usr/sbin/mysqld: Error while setting value '(SELECT
REPLACE(##sql_mode,'ONLY_FULL_GROUP_BY',''))' to 'sql_mode'.
Please help me, I'm fed up with this problem.
Just add GROUP BY YEAR(FIN_RESERVATION) to the end of your query or change it to MIN(YEAR(FIN_RESERVATION)) - you can also use max. If you didn't do these things and instead changed the mode MySQL would simply arbitrarily pick one of the year values anyway
Only full group by is a good thing
If you permanently want to disable only_full_group_by on startup, you can add:
sql-mode= "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"
To your my.ini or my.cnf under '[mysqld]'.
Also if you get the error:
"Error while setting value 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION' to 'sql_mode'"
as I did, you can get around this issue, by first clearing all sql-modes by putting sql-mode="" above:
sql-mode= "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"
You can't use an sql expression as the value of --sql_mode. Run SET SESSION sql_mode=(SELECT REPLACE(##sql_mode,'ONLY_FULL_GROUP_BY','')); SELECT ##sql_mode; in your server and use the value it shows with --sql_mode.
I ran the command as root:
set ##auto_increment_offset = 2;
But the effect cannot be seen from other connections. Why not? It is global.
From http://dev.mysql.com/doc/refman/5.1/en/replication-options-master.html:
"If the global value of either variable is set, its effects persist until the global value is changed or overridden by setting the session value, or until mysqld is restarted."
That doesn't seem to agree with what I am seeing.
Ultimately, I would like to know if there any way to permanently set the offset for all clients without restarting mysqld?
As per MySQL documentation you need to set values of auto_increment_offset for both GLOBAL and SESSION.
SET GLOBAL auto_increment_offset = 2;
SET SESSION auto_increment_offset = 2;
SHOW VARIABLES LIKE '%auto_increment_offset%';
If the global value of either variable is set, its effects persist until the global value is changed or overridden by setting the session value, or until mysqld is restarted. If the local value is set, the new value affects AUTO_INCREMENT columns for all tables into which new rows are inserted by the current user for the duration of the session, unless the values are changed during that session.
To set it globally you should add prefix 'GLOBAL' or '##global.'. For example -
SET ##GLOBAL.auto_increment_offset = 2;
The '##' is the same as 'SESSION' or '##session.', it sets session variable.
Using System Variables.
I'm retrieving the data with MySQL function called "GROUP_CONCAT()".
But when I checked the result of "GROUP_CONCAT()" function related column, it was missing some data.
When I google the record missing issue with "GROUP_CONCAT()" function, in the official MySQL site they have mentioned as,
There is a global variable called group_concat_max_len and it will permit the maximum result length in bytes for the GROUP_CONCAT() function, the default value of it as 1024.
Therefore it seems I have to increase that value with following MySQL command,
SET GLOBAL group_concat_max_len = 1000000;
Therefore set this value permanently, I have to edit the MySQL server related configuration file (my.cnf or my.ini) and have to restart the server.
But unfortunately I haven't any permission to do so.
Therefore can you please help me to find out some alternative solution to fix this issue.
Thanks a lot.
Use SET SESSION instead:
SET SESSION group_concat_max_len = 1000000;
Unlike SET GLOBAL, SET SESSION does not require super privilege.
Reference
Following this post: POST ABOUT CONCAT
My problem is that i have many rows CONCAT into one row. For example if i have 10 rows with string around 50 chars, my query will show me only 6-7 of that rows or something like that.
I searech in stack and google and i found that i can change CONCAT max length by command: SET group_concat_max_len := ##max_allowed_packet. What i am doing wrong?
EDIT:
When i SHOW VARIABLES LIKE 'group_concat_max_len' it's shows me 1024.
Mysql version 5.0.96-log. Tables type: MyISAM. Looks like it dont have any limits, i try to select simple varchar with 2000 chars, and it looks fine.
I have 3 tables: 1st - Item with ItemID, 2nd - Descriptionpack with ItemID and DescriptionID, 3rd Description with DescriptionID.
Select
DISTINCT Item.ItemID as item
,GROUP_CONCAT(Description.DescriptionID) AS description
From Item
LEFT OUTER JOIN descriptionpack
on Item.ItemID=descriptionpack.ItemID
LEFT OUTER JOIN description
on descriptionpack.descriptionID=description.descriptionID
GROUP BY item
EDIT2: I think i found the problem, i said my problem to my provider and they answer me this:
I reviewed your question with our hosting team. You wouldn't be able
to change the global settings for that and other variables. However,
you should be able to set that variable on a per session basis by
setting it first, before other queries. Hope that helps.
So now the problem is, how to do that.
Presumably you're using GROUP_CONCAT(), not simple CONCAT().
The default value of the group_concat_max_len is 1024, which is a pretty small limit if you're building up big long concatenations.
To change it, use this command. I've set the length in this example to 100,000. You could set it to anything you need.
SET SESSION group_concat_max_len = 100000;
The usual value for max_allowed_packet is one megabyte, which is likely more than you need.
group_concat_max_len itself has an effectively unlimited size. It's limited only by the unsigned word length of the platform: 2^32-1 on a 32-bit platform and 2^64-1 on a 64-bit platform.
If that still isn't enough for your application, it's time to take #eggyal's suggestion and rethink your approach.
You need change group_concat_max_len default value in the bellow config file
**my.cnf file(Linux) and my.ini file(windows)**
[mysqld]//Add this line group_concat_max_len=15000 under mysqld section
group_concat_max_len=15000
Note: After change is done You need to restart your MySQL server.
my.cnf file path in linux :
1. /etc/my.cnf
2./etc/mysql/my.cnf
3.$MYSQL_HOME/my.cnf
4.[datadir]/my.cnf
5.~/.my.cnf

This error occurs on a production environment so I don't know which query produced the problem, but I do know that none of my tables has a column named '123'. Do you have any suggestions about what might be causing this problem?
Edit: As a followup, I found that this behavior is a known bug in MySQL 5.0.4, but I haven't found a good wokaround since I don't have the option of upgrading mySQL.
Could be that somehow the character set for the field has been set to an invalid value, run this SQL on the server with the problem replacing the table name and the column 'Collation' will show the characterset for each varchar/char fields
SHOW FULL COLUMNS IN table_name;
You can then change the character set of a field by using the following:
ALTER TABLE t MODIFY col1 VARCHAR(50) CHARACTER SET latin1;
Internally, MySQL is mapping out the indexes across the columns. Normally this is done using integers that represent the column index. Most indexes are actually a compound index once built (col 1 + col 3) which form something like field 13.
Likely this happened when migrating data from dev into production when the stack is not an exact replica.
As 3urdoch mentioned you can pull the charset using internal MySQL function; and then change the table's charset to a compatible encoding.
Alternatively (where I'm willing to bet this issue came from) you can check if the loaded driver for the Production matches the loaded driver for the Other server. This will prevent re-occurring issue if the Development/Other server is still being used for testing, and migrated into Production.
