Setting global sql_mode in MySQL - mysql

Question

I am trying to set sql_mode in MySQL but it throws an error.
Command:
set global sql_mode='NO_BACKSLASH_ESCAPES','STRICT_TRANS_TABLE','NO_AUTO_CREATE_USER','NO_ENGINE_SUBSTITUTION'
Is this not the proper way to set multiple modes?
What are the advantages of setting session and global modes?
Which is preferred?
I have different users trying to update the database with different UNC values and instead of setting the session mode to NO_BACKSLASH_ESCAPES, I though it would make sense to set a global mode for this. Does this make sense?
Please let me know.
Thanks.

Answer 1

BTW, if you set globals in MySQL:
SET GLOBAL sql_mode = 'NO_ENGINE_SUBSTITUTION';
SET SESSION sql_mode = 'NO_ENGINE_SUBSTITUTION';
This will not set it PERMANENTLY, and it will revert after every restart.
So you should set this in your config file (e.g. /etc/mysql/my.cnf in the [mysqld] section), so that the changes remain in effect after MySQL restart:
Config File: /etc/mysql/my.cnf
[mysqld]
sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
UPDATE: Newer versions of Mysql (e.g. 5.7.8 or above) may require slightly different syntax:
[mysqld]
sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"
Make sure that there is a dash between sql-mode not an underscore, and that modes are in double quotes.
Always reference the MySQL Docs for your version to see the sql-mode options.

Answer 2

I resolved it.
the correct mode is :
set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Answer 3

Setting sql mode permanently using mysql config file.
In my case i have to change file /etc/mysql/mysql.conf.d/mysqld.cnf as mysql.conf.d is included in /etc/mysql/my.cnf. i change this under [mysqld]
[mysqld]
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
just removed ONLY_FULL_GROUP_BY sql mode cause it was causing issue.
I am using ubuntu 16.04, php 7 and mysql --version give me this mysql Ver 14.14 Distrib 5.7.13, for Linux (x86_64) using EditLine wrapper
After this change run below commands
sudo service mysql stop
sudo service mysql start
Now check sql modes by this query SELECT ##sql_mode and you should get modes that you have just set.

Answer 4

For someone who googling this error for MySQL 8.
MySQL 8.0.11 remove the 'NO_AUTO_CREATE_USER' from sql-mode.
MySQL 5.7: Using GRANT to create users. Instead, use CREATE USER.
Following this practice makes the NO_AUTO_CREATE_USER SQL mode
immaterial for GRANT statements, so it too is deprecated. MySQL
8.0.11: Using GRANT to create users. Instead, use CREATE USER. Following this practice makes the NO_AUTO_CREATE_USER SQL mode
immaterial for GRANT statements, so it too is removed.
Taken from here
So, your sql_mode can be like this:
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
Or if you're using Docker you can add next command to docker-compose.yml
mysql:
image: mysql:8.0.13
command: --sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
ports:
- 13306:${MYSQL_PORT}

Answer 5

Copy to Config File: /etc/mysql/my.cnf OR /bin/mysql/my.ini
[mysqld]
port = 3306
sql-mode=""
MySQL restart.
Or you can also do
[mysqld]
port = 3306
SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
MySQL restart.

Answer 6

Access the database as the administrator user (root maybe).
Check current SQL_mode
mysql> SELECT ##sql_mode;
To set a new sql_mode, exit the database, create a file
nano /etc/mysql/conf.d/<filename>.cnf
with your sql_mode content
[mysqld]
sql_mode=NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Restart Mysql
mysql> sudo service mysql stop
mysql> sudo service mysql start
We create a file in the folder /etc/mysql/conf.d/
because in the main config file /etc/mysql/my.cnf
the command is written to include all the settings files from the folder /etc/mysql/conf.d/

Answer 7

For Temporary change use following command
set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
For permanent change : go to config file /etc/my.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf and add following lines then restart mysql service
[mysqld]
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Answer 8

Check the documentation of sql_mode
Method 1:
Check default value of sql_mode:
SELECT ##sql_mode //check current value for sql_mode
SET GLOBAL sql_mode = "NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION";
Method 2:
Access phpmyadmin for editing your sql_mode
Login on phpmyadmin and open localhost
Top on Variables present on the top in menu items and search out for sql mode
Click on edit button to modify sql_mode based on your requirements
Save the changes
Restart server after executing above things

Answer 9

In my case mysql and ubuntu 18.04
I set it permanently using this command
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Append the line after the configuration. See example highlighted in the image below.
sql_mode = ""
Note :You can also add different modes here, it depends on your need
NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
See Available sql modes reference and Documentation
Then save.
After saving you need to restart your mysql service, follow the command below:
sudo service mysql restart
Hope this helps :-)

Answer 10

In my case i have to change file /etc/mysql/mysql.conf.d/mysqld.cnf change this under [mysqld]
Paste this line on [mysqld] portion
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Answer 11

I just had a similar problem where MySQL (5.6.45) wouldn't accept sql_mode from any config file.
The solution was to add init_file = /etc/mysql/mysql-init.sql to the config file and then execute SET GLOBAL sql_mode = ''; in there.

Answer 12

If someone want to set it only for the current session then use the following command
set session sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Answer 13

Updating this for users Using MAMP PRO {works with MAMP users too}. Because I seem to have got stuck on finding a solution for this, but people recommended I should edit the my.cnf file in the /Applications/MAMP/tmp/mysql/my.cnf folder which does not work because it gets reset after every restart of mysql server.
Referring this document:
The configuration file “my.cnf” of MySQL can be found here:
“/Applications/MAMP/tmp/mysql/my.cnf”. Please note: Editing this file
does NOT work as it will be overwritten every time MySQL is restarted
by MAMP PRO with a “my.cnf” file that is created from the MySQL
template. You must edit this template (menu File > Open Template >
MySQL (my.cnf) > 5.7.30) to modify the MySQL configuration. Manually
adding “my.cnf” files to other locations is not recommended. Every
configuration aspect can be handled with the MySQL template.
Once this is done, add the following in the my.cnf file:
[mysqld]
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Restart the Mysql Server. That should do the trick.

set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
