I am trying to use insert on duplicate key update in MySQL 8 like this:
INSERT INTO orders SELECT * FROM temporary_orders ON DUPLICATE KEY UPDATE column1='a';
But I get this error:
UPDATE command denied to user 'user'#'localhost' for column 'column1' in table 'orders';
Initially my user only had SELECT and UPDATE privileges, but now I gave the user global privileges and the error still occurs. Running:
INSERT INTO orders SELECT * FROM temporary_orders;
Works without the ON DUPLICATE KEY UPDATE portion. I am also able to run:
UPDATE orders SET column1='a';
My specific MySQL version is mysql Ver 8.0.16 for Linux on x86_64 (MySQL Community Server - GPL).
I ran this command to give my user global privileges:
GRANT ALL ON *.* TO 'user'#'localhost';
And running:
SHOW GRANTS FOR 'user'#'localhost';
Outputs:
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `user`#`localhost`
UPDATE
I've tested and using the root user does work, but I'm not sure what permission could be missing.
I ended up creating a new user and then granting all permissions like so:
GRANT ALL ON *.* TO 'user'#'localhost';
And it worked fine. Not sure what the problem was.

I am logged in as root user and i just reinstalled the mysql server. login_manager isn't created as is shown when i execute SELECT * FROM mysql.user;. I now execute
CREATE USER 'login_manager'#'localhost' IDENTIFIED BY 'login_manager'; and when i check if the user is created, i can find it. Executing
GRANT INSERT
ON clients
TO login_manager;
where client is a table gives me the error i put in the title. Executing FLUSH PRIVILEGES; after creating the user didn't help either. I flushed privileges before creating the user. I looked that up, and normally this error comes when you try to create the user in the grant statement, which i am not doing.
I know this is long, but here are the Grants that root has:
'GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `root`#`localhost` WITH GRANT OPTION'
and
'GRANT APPLICATION_PASSWORD_ADMIN,AUDIT_ADMIN,BACKUP_ADMIN,BINLOG_ADMIN,BINLOG_ENCRYPTION_ADMIN,CLONE_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GROUP_REPLICATION_ADMIN,INNODB_REDO_LOG_ARCHIVE,INNODB_REDO_LOG_ENABLE,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_APPLIER,REPLICATION_SLAVE_ADMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SERVICE_CONNECTION_ADMIN,SESSION_VARIABLES_ADMIN,SET_USER_ID,SHOW_ROUTINE,SYSTEM_USER,SYSTEM_VARIABLES_ADMIN,TABLE_ENCRYPTION_ADMIN,XA_RECOVER_ADMIN ON *.* TO `root`#`localhost` WITH GRANT OPTION'
and
'GRANT PROXY ON ''#'' TO 'root'#'localhost' WITH GRANT OPTION'
Your login_manager user has a Host entry, likely localhost or %.
Because of this, your GRANT technically isn't for that user, it's for a login_manager with no Host entry - so mysql knows it would have to create the user with no Host first.
Asuming you used localhost when you created the user, use this to do the grants:
GRANT INSERT
ON clients
TO 'login_manager'#'localhost';
Currently I have a master user in RDS like this
'master'#'%'
and I've create a user like this
'new_user'#'%'
As of now I can grant that user with these privileges
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER ON *.* TO 'new_user'#'%' IDENTIFIED BY '1234' WITH GRANT OPTION
Is it possible to grant these permission but with the limit of
DELETE PRIVILEGE? on a specific table like this tblCart
Like, I can delete on all but except for table tblCart deleting is not allowed in this table?
The old answer is wrong. Since you didn't define DELETE ON *.tblCart this wont work. You will have to revoke DELETE on all and add them manually.
REVOKE DELETE ON *.* FROM `new_user`#`%`;
GRANT DELETE ON <db>.<tbl1> TO `new_user`#`%`;
...
GRANT DELETE ON <db>.<tblN> TO `new_user`#`%`;
See this post for how to generate the statement for all tables.
Old answer
After you applied your grants the way you did bove you can revoke permissions from tblCart like so:
REVOKE DELETE ON *.`tblCart` FROM `new_user`#`%`;
This will keep all permissions on all tables but remove permission do delete rows from tblCart.
I have a strange issue. Im using Msql 8 via Docker and Im able to connect via IDE like DataGrip to connect to my db with root user. But only with root. Im trying to establish a connection with a non-root user but It is not working even with all privileges.
I thought I did something wrong when creating a new user, but in my local environment Im able to connect to my db with a non-root user.
This works:
mysql --user=test mysql -p
Priviligeses:
| GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `test`#`localhost` WITH GRANT OPTION |
| GRANT BACKUP_ADMIN,BINLOG_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GROUP_REPLICATION_ADMIN,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_SLAVE_ADMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SET_USER_ID,SYSTEM_VARIABLES_ADMIN,XA_RECOVER_ADMIN ON *.* TO `test`#`localhost` WITH GRANT OPTION
I know there are several similiar question and I tried all of them. But none of them worked or changed something.
Btw. I created my user this way:
CREATE USER 'test'#'localhost' IDENTITY BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'test'#'localhost';
I have a few users on my server who have access to every MySQL database. I'm trying to revoke privileges but I'm not sure how to go about it.
For example: I have a user bob who has access to every database on my server. I run the following to see which privileges bob has:
mysql -e "select * from information_schema.user_privileges;" | grep bob
'bob'#'%' def SELECT NO
'bob'#'%' def INSERT NO
'bob'#'%' def UPDATE NO
'bob'#'%' def DELETE NO
'bob'#'%' def CREATE NO
'bob'#'%' def FILE NO
'bob'#'%' def CREATE USER NO
Nothing jumps out like GRANT, ALL or SUPER. I create a new database sometest, switch to bob's account and see that bob has access to sometest. Not sure what I am missing here.
Edit: I ran SHOW GRANTS FOR 'bob'#'%'; and see:
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN,
PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES,
LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW,
CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE
ON *.* TO 'bob'#'%'
1) How does one drop this permission? I assume if I run:
REVOKE SELECT, INSERT,... on *.* to 'bob'#'%';
it will remove permissions like
GRANT ALL ON bobsdb.* TO 'bob'#'%';
which I don't want to happen. But maybe it's best to just remove all privileges and build them back up from scratch.
2) How does one identify all permissions like this? Do I have to look over every user?
You should be able to view the users' grants using the command:
SHOW GRANTS FOR 'bob'#'localhost';
From the MySQL manual:
The SHOW DATABASES privilege enables the account to see database names by issuing the SHOW DATABASE statement. Accounts that do not have this privilege see only databases for which they have some privileges, and cannot use the statement at all if the server was started with the --skip-show-database option. Note that any global privilege is a privilege for the database.
If SHOW DATABASES is enabled, revoke that permission.
REVOKE SHOW DATABASES ON *.* FROM 'bob'#'localhost';
Lastly, reload all the privileges using the command:
FLUSH PRIVILEGES;
(or restart MySQL - if that's an option - often it's not).
P.S: You might need to replace 'localhost' with your db hostname.

Edit:
To answer your questions:
1) How does one drop this permission? I assume if I run: REVOKE SELECT, INSERT,... on *.* to 'bob'#'%';
You could simply run REVOKE ALL ON *.* TO 'bob'#'%';
2) How does one identify all permissions like this? Do I have to look over every user?

I have a problem when I create a new user in mySQL 5.6
What I want:
When I create the new user, it doesn't have any privileges, and I just want to grant some select and update in a few specific columns. So he should be able to update just anything at all the DB. Sounds fair.
So, first, I create a new user:
CREATE USER 'newuser'#'%' IDENTIFIED BY 'password';
After this, I log in with my new user and when I do a show grants; command I have this:
GRANT USAGE ON *.* TO 'newuser'#'%' IDENTIFIED BY PASSWORD '*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19'
So in my theory he cant do anything in my database bacause he doesn't have any GRANT SELECT privilege.
But when I do a select in my test table he can view all columns and all results. He can update ... and do everything he wants to. It's like he have a GRANT SELECT,UPDATE,DELETE ... ON *.* TO 'newuser'#'%' but I can't revoke that because he doesn't have that.
Of course, I've tried to revoke all privileges, but I can't because he doesn't have any privileges.
I hope i'm clear. So I'm confused, any ideas?
Thanks!

In many default installations, all users have all privileges on tables within any database called test or beginning with test_.
From http://dev.mysql.com/doc/refman/5.6/en/default-privileges.html#idp5999952 :
By default, the mysql.db table contains rows that permit access by any user to the test database and other databases with names that start with test_. ...If you want to remove any-user access to test databases, do so as follows:
mysql> DELETE FROM mysql.db WHERE Db LIKE 'test%';
mysql> FLUSH PRIVILEGES;
Alternatively, make sure that your test table isn't in a database with such a name, and then you'll see the true behaviour.
