A client has just supplied me with two long files which are (apparently) scripts that I can run in MySQL to generate a bunch of database tables.
I've installed MySQL (+ workbench) on my PC. From within the Workbench environment I found "run SQL script" under the File menu so I went with that and tried to run the two script files I have. They both fell over partway though giving me error messages:
Finished executing script
ERROR 2006 (HY000) at line 1930: MySQL server has gone away
Operation failed with exitcode 1
and
Finished executing script
ERROR 2006 (HY000) at line 20201: MySQL server has gone away
Operation failed with exitcode 1
I can however see two schemas, both of which contain a bunch of tables, etc. (some of which are populated) so it seems to have been a partial success at least.
Can anyway suggest what might be wrong please?
Thank you.
I can point you at a solved example on stackoverflow for this MySQL error, but the simplest solution is to edit your sql file(s) placing this query at the top:
set SESSION max_allowed_packet=64*1024*1024

I've tried Google no luck, tried migration on both the source and target servers no joy.
any ideas?
In my case was that needs the input of the password of mysql admin (wasn't asked need to click on the "store in vault" button).
I have a D8 google mysql instance. I'm running an etl process trying to push about 100GB of data in but the script keep stopping because of the error.
In order to get it working I have to restart the mysql instance and then re run the process from where it failed. Any help is greatly appreciated. I haven't found anything on google.
This error tends to mean the connection to the MySQL server was lost at some point. As mentioned in this 'Lost connection to MySQL server' article, this error may be encountered when writing a significant number or rows.
The article suggests setting the net_read_timeout to something greater than the default value of 30 seconds. You may also want to consider breaking up your write tasks as well.
I have the following error on execute sql file or creating database by entity framework code first approach
Error writing file '.\dbdemo\ads.frm' (Errcode: 28)
On local database server it is working fine and creating database by EF Code First Approach but
on my website hosting server facing this problem.I have tried both techniques by executing sql file and creating database EF Code First Approach both failed.
Any idea how to solve this error !
Use the perror command:
$ perror 28
OS error code 28: No space left on device
Unless error codes are different on your system, your file system is full.
Refer MySQL Docs.
This blog explains about the error. And this too.
MySQL created a temporary table, using the MyISAM storage engine, and when the disk filled up, MyISAM got an error.
So try clearing the temp folder.
I have an issue where our database is receiving ~1000 updates a minute, and often we get an error response:
TAF: 1297 (HY000) at line 1: Got temporary error 899 'Rowid already allocated' from NDBCLUSTER
which appears in our application to our customer.
Is there any way to suppress these errors at the MySQL level? As I am not the developer of this application, I am not sure what language is performing the updates, but I presume either shell script or a C program.
I am using MySQL: 5.1.44-ndb-7.1.3-cluster-log (2 cluster nodes and 1 cluster mgmt node)
Have you tried using the 'IGNORE' clause in your SQL statements, the documentation for this is here
Using the IGNORE clause will downgrade errors to warnings, these warnings are displayed using the 'SHOW WARNINGS;' command
Please help me to get rid of this errors
While i run some large number of mysql scripts at once i got this kind of errors
ERROR: 2006 MySQL server has gone away Error: 1153 Got a packet
bigger than 'max_allowed_packet' bytes
How to get rid of this error, im using Navicat mysql and WAMP server??
In running scripts i choose continue on error so scripts still running with error msgs and values in Message log. Will this work and can i run the error values later??
try using these commands from mysql terminal
set global max_allowed_packet=1000000000;
set global net_buffer_length=1000000;
The answer from ayush solves it, but if you un-check the option "Run multiple queries in each execution" in the dialog box when executing SQL file it might do the trick as well (but the execution will take longer to run).
