I need to give an user TRIGGER permission for an whole schema in mysql to import mysql workbench backup.
I tried with:
grant trigger ON `schemaname`.* TO `user`#`localhost`
But while importing there comes the error that the user haven't the permissions.
ERROR 1142 (42000) at line 53: TRIGGER command denied to user 'user'#'localhost' for table 'table'
I tried to give the user TRIGGER permission to the table - that works, but of course only for that table, for the others still came the error.
Is there any way to give an user trigger permission to an schema without giving him the permission for every table separately?
From MySQL Docs
In MySQL 5.0 CREATE TRIGGER requires the SUPER privilege.
So you need to give SUPER privileges to the User. While importing, there will be command like "Create Trigger..." which is throwing an error.
Check your MySQL version and definer value as well for trigger in the importing file.
Edit:
For version 5.1, follow MySQL docs, that says:
CREATE TRIGGER requires the TRIGGER privilege for the table associated with the
trigger. The statement might also require the SUPER privilege, depending on
the DEFINER value, as described later in this section. If binary logging is
enabled, CREATE TRIGGER might require the SUPER privilege, as described in
Section 19.7, “Binary Logging of Stored Programs”. (Before MySQL 5.1.6, there is
no TRIGGER privilege and this statement requires the SUPER privilege in all cases)
The DEFINER clause determines the security context to be used when checking access
privileges at trigger activation time.
So, you need to check Definer value for importing trigger. It might have something like : DEFINER = root. Try removing the definer then try importing. Hope it works...
In MySQL docs:
To relax the preceding conditions on function creation (that you must have the
SUPER privilege and that a function must be declared deterministic or to not
modify data), set the global log_bin_trust_function_creators system variable
to 1. By default, this variable has a value of 0, but you can change it like
this:
mysql> SET GLOBAL log_bin_trust_function_creators = 1;
You can also set this variable by using the
--log-bin-trust-function-creators=1
option when starting the server.
Set the global variable and reopened the session I was able to insert the trigger

I want to execute the following trigger in the dev environment. This trigger works fine locally (local user does not have super privilege and log bin is enabled). Here is the trigger
DELIMITER $$
USE `myschema`$$
CREATE
DEFINER=`user`#`localhost`
TRIGGER `myschema`.`roles_BEFORE_INSERT`
BEFORE INSERT ON `myschema`.`roles`
FOR EACH ROW
BEGIN
IF (NEW.role_id IS NULL) THEN
-- Find max existed role id
SELECT
MAX(role_id) INTO #max_role_id
FROM
roles;
IF (#max_role_id IS NULL) THEN
-- Set first role id
SET NEW.role_id = CONCAT('RID', '0001');
ELSE
-- Set next role id
SET NEW.role_id = CONCAT(SUBSTR(#max_role_id, 1, 3), LPAD(SUBSTR(#max_role_id, 4) + 1, 4, '0'));
END IF;
END IF;
END$$
I am getting the following error while executing the above script in dev environment where I do not have access to check whether user has what privileges and log bin is enabled or not. Could you please tell me is there any way I can specify super privilege or setting the log bin enable query along with the above script itself. I am having a hard time as the issue is not reproducible in local environment. Any help is appreciated.
SQL State : HY000
Error Code : 1419
Message : You do not have the SUPER privilege and binary logging is enabled
(you might want to use the less safe log_bin_trust_function_creators variable)
Someone who has SUPER privilege must grant it to you, or create your trigger themselves. It's the same kind of thing as Administrator priv on Windows or root priv on *nix.
To check current user grants:
login with user in mysql and
mysql> show grants;
to check supper user:
mysql>select user,host from mysql.user where super_priv='y';
to check bonlog:
mysql> show global variables like "log_bin";
Fix:
you can fix it by enabling log_bin_trust_function_creators
mysql> set global log_bin_trust_function_creators =ON;

I'm running a mysql 5.6 server on amazon RDS and set up a read replica I use to create backups using mysqldump.
I tried with the "--all-databases" option, but when I'm trying to import the SQL created by mysqldump, I end up with this error from the mysql command client:
ERROR 1465 "Triggers can not be created on system tables"
I used "--all-databases" because I basically want to restore everything in RDS as it was before in case of a crash.
Maybe that's wrong, and I should only select my schemas (plus the mysql.users table)? But what is "--all-databases" for in the first place, if it would never work? Or am I using it wrong?
After a longer conversation with the amazon support, this is what I came up with:
The trigger problem can be solved by temporarily setting the mysql config setting log_bin_trust_function_creators to 1
They do not recommend to take a full snapshot, but rather select individual databases.
That means you have to do two steps in an recovery:
Create Schema
Create Users and grant necessary rights to them
Import dumped data
With views, you might run into the error message
ERROR 1227 (42000) at line xxx: Access denied; you need (at least one of) the SUPER privilege(s) for this operation
Which is displayed because mysqldump creates a definer statement into the create view (and even your root user doesn't have enough privileges to set this). As described here, the only way to get rid of them is filtering, which I do like this:
sed -i 's/^/..50013 DEFINER=.* SQL SECURITY DEFINER ..$/-- removed security definer statement/g'
It's embarrassing that there is so much manual work needed to get database backups out of RDS, and also back in. Under no circumstances you should rely on the backups which are automatically made by RDS only, as those could be easily deleted by a malicious attacker that gained access to your AWS account.
Import with mysql -f to skip the offending proc.
In my case the skipped definition was this little gem:
DELIMITER ;;
/*!50003 CREATE*/ /*!50017 DEFINER=`rdsadmin`#`localhost`*/ /*!50003 trigger block_proc_u before update on proc
for each row
BEGIN
DECLARE foo varchar(255);
if old.Definer = "rdsadmin#localhost" then
select `ERROR (RDS): CANNOT MODIFY RDSDMIN OBJECT` into foo;
end if;
END */;;
Plus another four very similar ones (total five skipped).
I am trying to audit the privilege changes in mysql.user table by writing a trigger on it.
insert trigger: will capture who gave the new permissions and when
update trigger: will capture who changes the privileges from what[old privilege]
remove trigger: will capture who removed the privileges and what are they
Now, I am getting an error while writing like
ERROR 1465 (HY000): Triggers can not be created on system tables
Can we create a trigger on system tables, Is there any work around or it will be supported in higher versions[> 5.1.61] ?
Thanks in advance.
No we can not. Even if we have the best concerned privileges are all and super
See (All) and (Super) Privileges Provided by mySql
After trying all type of privileges like
grant super on *.* to root#localhost
grant all on *.* to root#localhost
I have tried simplest trigger on different tables mysql.db and got same error
Triggers can not be created on system tables // Please accept this
bitter truth
If you found anywhere that triggers can be created on system tables, simply that is wrong

The poster says he needed "SUPER PREVILAGES"
Do you have access to the root user for the database?
I am logging in with my main DB user, into Phpmyadmin page/ workbench remote access application and I have permissions issues.
It all started when I tried to alter routines that I have stored in the DB. when trying to alter those routines from the workbench applications nothing just happens.
I can call these routines and execute them, but not alter or get to the scripts.
I searched for hours in distinct forums and get some answers regarding grant access commands
but then I got again permissions issues with error #1142 , command denied to user(main user).
I am really lost here, and already lost hours of work in order to get to the scripts of my routines.
one last note - I have created these routines while I was connected with the same user but from different remote connection (different IP address).
Would really appreciate the help.
here is a solution how I fixed this:
1) Add "mysql" database to the user, you are logged in with
Advice: now you can alter functions and procedures
2) Add the global privilege "SUPER" to your user
Advice: otherwise you will get the following error if you save the procedure/function: "ERROR 1227: Access denied; you need (at least one of) the SUPER privilege(s) for this operation"
CREATE DEFINER = 'admin'#'localhost' PROCEDURE account_count()
SQL SECURITY INVOKER
BEGIN
SELECT 'Number of accounts:', COUNT(*) FROM mysql.user;
END;
See the above example.
You need to login using super user and change the definer parameter in the procedure based on your new username and hostname. The same definer who created can edit the stored procedure.
I have created stored procedures in **MySQL database on my local machine and when i generate the script to run it on the host server i have this error**
#1227 - Access denied; you need the SUPER privilege for this operation
and this is the code
CREATE DEFINER = `User_name`#`host_name` PROCEDURE `InsertOrder`
and this user_name take all the privilege ,so any one can help please?
As the manual says:
If you do not have the SUPER privilege, the only permitted user value is your own account, either specified literally or by using CURRENT_USER. You cannot set the definer to some other account.
You must either issue the command using an account which has the SUPER privilege, or else change the DEFINER to your current user account (which is the default if it's omitted).
