Mysql – How to disable thesql_native_password and thesql_old_password on MariaDB / MySQL

mariadbMySQL

I only want to use unix_socket as the sole authentication method.
Both mysql_native_password and mysql_old_password are installed and enabled by default, but I'd like to disable them.

I'm unable to uninstall them:

MariaDB [(none)]> uninstall plugin mysql_native_password;
ERROR 1619 (HY000): Built-in plugins cannot be deleted

I've followed the instructions here:
https://mariadb.com/kb/en/mysql_plugin/

I've created disabled_plugins.ini in /etc/mysql with contents:

disabled_plugins
mysql_old_password

Then:

MariaDB [(none)]> mysql_plugin disabled_plugins DISABLE;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'mysql_plugin disabled_plugins DISABLE' at line 1

This is on WSL1 and 10.3.27-MariaDB-0+deb10u1-log Debian 10

Can someone help?

Thanks

Best Answer

You are suppose to run this command from server command line not from MariaDB console.

mysql_plugin disabled_plugins DISABLE

And then login to MariaDB & check :

SELECT * FROM mysql.plugin;

Are you sure you still have an error with the following script ?

change :

CREATE TABLE IF NOT EXISTS `mydb`.`Order_has_Product` (
  `Order_id` INT{+ NOT+} NULL,
  `Product_product_id` INT{+ NOT+} NULL,

(it work on my MySQL 5.7, I don't have any mariadb to try now)

Mysql – Can MariaDB or MySQL cast as bigint, getting an error: … right syntax to use near ‘bigint)’

Silently? Let's try:

CREATE TABLE g
   AS SELECT CAST('2147483699' AS int);

MariaDB 10.1.32, default sql_mode (non-strict)

Query OK, 1 row affected, 1 warning (0.19 sec) Records: 1 Duplicates: 0 Warnings: 1

And the warning is:

| Warning | 1264 | Out of range value for column 'CAST('2147483699' AS int)' at row 1 |

Yes, selecting from the table is interesting, but not surprising given the warning.

(I don't have a MariaDB 10.2 instance at the moment, but testing on dbfiddle.uk indicates it too fails, though again not silently.)

MariaDB 10.3.6, default sql_mode (strict)

No warnings.

select * from g;

Gives:

+---------------------------+
| CAST('2147483699' AS int) |
+---------------------------+
|                2147483699 |
+---------------------------+
1 row in set (0.000 sec)

And the column is indeed created as bigint(10).

MySQL 8.0, both the default strict and non-strict sql_mode

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'int)' at line 2

Computer says no.

Conclusion

Can MariaDB or MySQL cast as bigint? As we have seen, yes, MariaDB 10.3 can (though it's not GA yet ... but surely any day now it will be). However, it can only cast as bigint implicitly. You can't explicitly cast as bigint, just like you can't cast as varchar (but see MDEV-11283), text, float, tinyint etcetera. There are only a limited number of datatypes you can cast to. This is not well documented, but CAST appears to support only the same datatypes as listed for the CONVERT function.
