SQL syntax error at simple statement - mysql

I'm trying to execute
ALTER USER 'root'#'localhost' IDENTIFIED BY 'my_new_password';
but getting
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 'IDENTIFIED BY 'my_new_password'' at line 1
What am i doing wrong?


The way you want to change the password is only valid since MySQL 5.7.6. You can use the SET PASSWORD statement for older versions instead:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('my_new_password');
The ALTER USER statement is available since MySQL 5.7.6. Make sure you are using this version or a newer one to use your statement (thx #Dez).

MySql syntax error during user creation when there is no apparent error

I'm trying to install Moodle using Ubuntu using the following guide: Step-by-step Installation Guide for Ubuntu
I'm currently on step 6 where I have to create a mySQL user with the correct permissions and this is where I'm getting stuck.
The 1st command - create user 'user1'#'localhost' IDENTIFIED BY 'password1'; works fine
However the 2nd command -
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO user1#localhost
IDENTIFIED BY 'password1';
Returns the error message - 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 'IDENTIFIED BY 'password1'' at line 1
The installation manual mentions that this may be a problem so advises me to use - SELECT password('password1'); in order to get a hash value to overcome the problem.
However instead of giving me a hash value it comes up with the same error of - 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 '('password1')' at line 1
I am a beginner to all this so I'd appreciate any responses, thanks in advance!

You need apostrophes around the name and the host in your command, like:
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO 'user1'#'localhost'
IDENTIFIED BY 'password1';
EDIT
According to the comments, slightly changing the command fixed the syntax error:
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO 'user1'#'localhost';

First Create user ‘moodleuser’#’localhost’ identified by ‘yourpassword’;
Then grant select,insert,update,delete,create,create temporary tables,drop,index,alter on moodle.* to 'moodleuser'#'localhost';

Unable to update root Mysql Password

I am unable reset mysql password using below query:
UPDATE mysql.user
SET authentication_string=PASSWORD('root')
WHERE user='root'
and host='localhost';
i am getting below error:
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 '('root') WHERE User = 'root' AND Host = 'localhost'' at line 1

As #spencer7593 points out, the PASSWORD() function was removed in MySQL 8.0 so this code won't work any longer even if it did in previous versions. The syntax error arises because, not recognizing that as a function, the ( character following it is unexpected and a syntax error.
This is because in addition to (previously) being a function it still a keyword.
The way you should be adjusting passwords is either through the mysqladmin command-line tool, or via the SET PASSWORD statement:
SET PASSWORD FOR 'root' = '...'

Error 1064 while running PASSWORD function in mysql

I've been busting my ass from last two days to update authentication_string of my root user and mysql is throwing ERROR 1064 at my face. I've tried every option I could (of course except the correct one which I don't know XD. After logging in as ROOT, I tried this code.
mysql> UPDATE MYSQL.USER SET AUTHENTICATION_STRING = PASSWORD('OJ') WHERE `USER` = 'ROOT';
And I'm getting following error.
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 '('OJ') WHERE `USER` = 'ROOT'' at line 1
I can't figure out what's going wrong here.
Thank you.

SQL database with column in the tablename

I have an error in my MySQL statement (using shell file), which I can't seem to resolve. Tried to put quotes etc but no luck. When I created it using phpmyadmin it works, but I want to have it scripted. Must be something small... Any ideas?
--- Create mySQL database ---
CREATE DATABASE IF NOT EXISTS _test-123;
CREATE USER 'test-123'#localhost IDENTIFIED BY '***';
GRANT ALL PRIVILEGES ON _test-123.* TO 'test-123'#'localhost';
FLUSH PRIVILEGES;
Enter password:
ERROR 1064 (42000) at line 1: 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 '-123' at line 1

Try removing the "-" and do this one instead-
CREATE DATABASE IF NOT EXISTS _test_123;

MySQL Master-Master Replication

I am trying to run the following query in MySQL:
GRANT REPLICATION SLAVE ON *.* TO 'replication'#’10.141.2.%’ IDENTIFIED BY ‘slave’;
It keeps returning the following error:
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 '??10.141.2.%’ IDENTIFIED BY ‘slave’' at line 1
What am i doing wrong?
Thanks.

You are using "fancy quotes" (see how they 'lean') ? Replace ’ with '
'replication'#’10.141.2.%’ should be 'replication'#'10.141.2.%'
(also, it appears you are doing it on IDENTIFIED BY ‘slave’; as well)
