How to turn on/off MySQL strict mode in localhost (xampp)?

Question

I want to know how to check whether MySQL strict mode is on or off in localhost(xampp).

If on then for what modes and how to off.

If off then how to on.

Answer 1

In my case, I need to add:

sql_mode="STRICT_TRANS_TABLES"

under [mysqld] in the file my.ini located in C:\xampp\mysql\bin.

Answer 2

on Debian 10 I start mysql from ./opt/lampp/xampp start

I do strace ./opt/lampp/sbin/mysqld and see that my.cnf is there:

stat("/opt/lampp/etc/my.cnf", {st_mode=S_IFREG|0644, st_size=5050, ...}) = 0
openat(AT_FDCWD, "/opt/lampp/etc/my.cnf", O_RDONLY|O_CLOEXEC) = 3

hence, I add sql_mode config to /opt/lampp/etc/my.cnf instead of /etc/mysql/my.cnf

Answer 3

To Change it permanently in ubuntu do the following

in the ubuntu command line

sudo nano /etc/mysql/my.cnf

Then add the following

[mysqld]
sql_mode=

Answer 4

You can check the local and global value of it with:

SELECT @@SQL_MODE, @@GLOBAL.SQL_MODE;

Answer 5

on server console:

$ mysql -u root -p -e "SET GLOBAL sql_mode = 'NO_ENGINE_SUBSTITUTION';"
