I'm a new beginner about Mysql
When I initialize the database after executing an exe files, inserting data cannot be executed
Then I print a general log and try to find why, the insert statement is shown below and there is no detailed error information
enter image description here
However I check the error-log, there is no related information, and I try to run the same insert statement in command line and it can be executed.
So I want to why is it? Or at least let me know is there any error information
Thanks
Here is the code to open genral log in my.init:
log-bin=mysql-bin
binlog_format=mixed
log-output=FILE
general-log=1

I run a web application on a shared LiteSpeed server with Mariadb version 10.3.22. I do have access to a terminal.
Cron is set up to perform a daily mysqldump, but I now get the error message:
mysqldump: Error 1412: Table definition has changed, please retry transaction when dumping table `TABLENAME` at row: 0
I do get a sql file, but it is a little smaller than it used to be. The table that is claimed to have changed it's definition is empty, just as it use to be (as far as I know).
I do not know much about mysql, and I do not understand the message "retry transaction when dumping table TABLENAME at row: 0"
Any clues about how to deal with that?
Please check the general log file of mysql service has "TRUNCATE" command on the table or not.
"TRUNCATE" command on the table during the mysqldump process changes table information and changing the command to "DELETE" command solved issue to me.
Default location of general log file is "/var/log/mysql/mysql.log" but it could be changed by "general_log_file" option and "general_log" option on "my.cnf" file.
If you are using mysql and getting error of "table defination has changed, please retry transaction " you have to do only one thing that is reconnect to DBMS, it will definitely solve the problem , tere is a button of "reconnect to DBMS" at home Page.
I am trying to view the MySQL binlog files to trace down the source of a particular query. I used the SHOW BINARY LOGS query to get the names of the existing log files, but when trying to access using the mysqlbinlog command, I keep getting an error: "File 'xxxx' not found (Errocode: 2 "No such file or directory")".
I also tried accessing the file using the full path /mysql/binlog/mysql-bin/file-name and with double forward slashes and back slashes, but just got the same error. I tried a couple of different files, all gave the same error.
If anyone can explain what I am doing wrong, that would be appreciated.
Mysqlbinlog utility checks your local file system, in this case. For remote server connection, you should use the --read-from-remote-server option in your command line. You can read related detail on the "4.6.8 mysqlbinlog — Utility for Processing Binary Log Files" page.
it started out with a mysqldump not making a good file so importing to another server would bomb. The last line of the sql file has this text in it:
mysqldump: Couldn't execute 'show events': Cannot proceed because system tables used by Event Scheduler were found damaged at server start (1577)
I then searched on this site for some other options and found the option of jsut grabbing the folder that contains the database and moving it to the other server. I tried that but then i get:
SQL show index from archived_import_log failed : Table 'cgaxf_800080.archived_import_log' doesn't exist
Now i am at a loss..any ideas?
I try to create a database file. I've checked the route and everything, I've tried several times to create the tablespace (I've changed to capital letter, the ' for "...) like this...
create tablespace uinstitucion datafile 'C:\app\uinstitucion\oradata\uinstitucion\uinstitucion.dbf' size 500M ;
file create error, unable to create file", "unable to open file", "(OS 5) access denied" (but I am logged as SYSTEM!)
... as you can see, I was just lead to several errors. What can I do? What am I doing wrong? I'm desperate since yesterday, and my teacher does not seem to notice the exact error.
I've also tried the order like
CREATE TABLESPACE lmtbsb DATAFILE 'file_path/lmtbsb01.dbf' SIZE 50M
EXTENT MANAGEMENT LOCAL AUTOALLOCATE;
but it leads me to the same error.
I'm sorry I cannot post a picture, it would be more descriptive, but I am not allowed yet.
Please run your SQLplus as an administrator and then connect and try to execute it.
You error says that you have no privileges to create file. This comes from operating system. Path looks for Windows so please try right click on SQLplus (or any other client you're using), choose run as administrator and then continue.
Is here a way to check if there is already a log file where mysql is writing general logs?
I'm trying to start my sql with command: --general-log-file="" to see what kind of queries are being sent to the server but that command is not working.
check for log_output
If the value is NONE log entries are not written even if the logs are enabled. If the logs are not enabled, no logging occurs even if the value of log_output is not NONE.
if it is not None then check for log file name using this file_name
