FROM `tbl_supplier_list` `a`
LEFT JOIN `view_quotes` `b`
ON (`b`.`quote_id` = `a`.`quote_id`)
LIMIT 0, 30
The error message is:
#1449 - The user specified as a definer ('web2vi'@'%') does not exist
Why am I getting that error? How do I fix it?

For future googlers: I got a similar message trying to update a table in a database that contained no views. After some digging, it turned out I had imported triggers on that table, and those were the things defined by the non-existant user. Dropping the triggers solved the problem.
In my case, the table had a trigger with a DEFINER user that didn't exist.
This happened to me after moving the DB from one server to another server. Initially, the definer was using localhost and the user. On the new server we don't have that user, and host had also been changed. I took a back up of that particular table and removed all the triggers manually from phpmyadmin. After that it has been working fine for me.
My 5 cents.
I had same error while I tried to select from a view.
However problem appears to be that this view, selected from another view that was restored from backup from different server.
and in fact, YES, user was invalid, but was not obvious where to from the first look.
quick fix to work around and dump the file:
mysqldump --single-transaction -u root -p xyz_live_db > xyz_live_db_bkup110116.sql
in my case I had a trigger on that table that I could not update data getting the same error.
MySQL error 1449: The user specified as a definer does not exist
the solution was to delete the triggers on that table and recreate them again, this fixed the issue, since the the trigger was made with another user from another server, and the user name changed on the new server after changing hosting company . that's my 2 cents
Why am I getting that error? How do I fix it?
I spent a hour before found a decision for a problem like this. But, in my case, I ran this:
mysql> UPDATE `users` SET `somefield` = 1 WHERE `user_id` = 2;
ERROR 1449 (HY000): The user specified as a definer ('root'@'%') does not exist
If you really want to find the problem, just run this commands one by one:
SHOW PROCEDURE STATUS;
SHOW FUNCTION STATUS;
SHOW TRIGGERS;
SHOW FULL TABLES IN database_name WHERE TABLE_TYPE LIKE 'VIEW';
...and, after each of them, look for the field 'definer'.
In my case it was bearded old trigger, that somebody of developers forgot to delete.
As addition, to change definer for TRIGGERS (ALTER does not work), you can do it like this:
Generate a DROP and a CREATE command for every Trigger:
SELECT CONCAT("DROP TRIGGER ", trigger_name, ";", " CREATE TRIGGER ", TRIGGER_NAME, " AFTER ", EVENT_MANIPULATION, " ON ", EVENT_OBJECT_SCHEMA, ".", EVENT_OBJECT_TABLE, " FOR EACH ROW ", ACTION_STATEMENT, ";") AS sqlCommand FROM information_schema.triggers WHERE EVENT_OBJECT_SCHEMA = "yourdatabase";
Execute it in a foreach. I use this in my app when I take the production database to my development machine and go it with a foreach over all commands and recreate the triggers automatically. This gives me the option to automate it.
Example in PHP/Laravel:
$this->info('DROP and CREATE TRIGGERS');
$pdo = DB::connection()->getPdo();
$sql = 'SELECT CONCAT("DROP TRIGGER ", trigger_name, ";", " CREATE TRIGGER ", TRIGGER_NAME, " AFTER ", EVENT_MANIPULATION, " ON ", EVENT_OBJECT_SCHEMA, ".", EVENT_OBJECT_TABLE, " FOR EACH ROW ", ACTION_STATEMENT, ";") AS sqlCommand FROM information_schema.triggers WHERE EVENT_OBJECT_SCHEMA = "mydatabase";';
$stmt = $pdo->prepare($sql, [PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true]);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
$stmt->closeCursor();
foreach($result as $rs){
$pdo = DB::unprepared($rs['sqlCommand']);
break;
}
Hint: I have to do it with pdo because of the mysql buffer query problem, described here
The database user also seems to be case-sensitive, so while I had a root'@'% user I didn't have a ROOT'@'% user. I changed the user to be uppercase via workbench and the problem was resolved!
I got the same error after updating mysql.
The error has been fixed after this command:
mysql_upgrade -u root
mysql_upgrade should be executed each time you upgrade MySQL. It checks all tables in all databases for incompatibilities with the current version of MySQL Server. If a table is found to have a possible incompatibility, it is checked. If any problems are found, the table is repaired. mysql_upgrade also upgrades the system tables so that you can take advantage of new privileges or capabilities that might have been added.
I have tried the above methods, but feels like repetitive action when creating the view. I got the same issue while updating the views of the imported database.
You can simply overcome the issue in LOCAL by simply creating the User with the create privilege.
you can create user with name web2vi
and grant all privilage
Go into the edit routine section and and at the bottom, change Security Type from Definer to Invoker.
I had your very same problem minutes ago, I ran into this issue after deleting an unused user from mysql.user table, but doing an alter view fixed it, here is a handy command that makes it very simple:
SELECT CONCAT("ALTER DEFINER=`youruser`@`host` VIEW ",
table_name," AS ", view_definition,";") FROM
information_schema.views WHERE table_schema='databasename'
Mix this with the mysql command line (assuming *nix, not familiar with windows):
> echo above_query | mysql -uuser -p > alterView.sql
> mysql -uuser -ppass databasename < alterView.sql
Note: the command generates and extra SELECT CONCAT on the file, making mysql -uuser -ppass databasename < alterView.sql
fail if you don't remove it.

This happened to me after I imported a dump on Windows 10 with MYSQL Workbench 6.3 Community, with "root@% does not exist". Even though the user existed. First I tried to comment out the DEFINER however, this did not work. I then did a string replace on "root@%" with "root@localhost" and reimported the dump. This did the trick for me.
Solution is just a single line query as below :
grant all on *.* to 'ROOT'@'%' identified by 'PASSWORD' with grant option;
Replace ROOT
with your mysql user name.
Replace PASSWORD
with your mysql password.
Try the following:
mysqldump --routines --single-transaction -u root -proot portalv3 > c:\portal.sql
This commonly occurs when exporting views/triggers/procedures from one database or server to another as the user that created that object no longer exists.
You have two options:
This is possibly easiest to do when initially importing your database objects, by removing any DEFINER
statements from the dump.
Changing the definer later is a more little tricky:
Run this SQL to generate the necessary ALTER statements
SELECT CONCAT("ALTER DEFINER=`youruser`@`host` VIEW ",
table_name, " AS ", view_definition, ";")
FROM information_schema.views
WHERE table_schema='your-database-name';
Copy and run the ALTER statements
Example:
UPDATE `mysql`.`proc` p SET definer = 'user@%' WHERE definer='root@%'
Be careful, because this will change all the definers for all databases.
If you've found following error while using MySQL database:
The user specified as a definer ('someuser'@'%') does not exist`
Then you can solve it by using following :
GRANT ALL ON *.* TO 'someuser'@'%' IDENTIFIED BY 'complex-password'; FLUSH PRIVILEGES;
From http://www.lynnnayko.com/2010/07/mysql-user-specified-as-definer-root.html
This worked like a charm - you only have to change someuser
to the name of the missing user. On a local dev server, you might typically just use root
.
Also consider whether you actually need to grant the user ALL
permissions or whether they could do with less.
Follow these steps:
Hope it helps
If the user exists, then:
mysql> flush privileges;
i came here for the same problem, i couldn't find anywhere in my code where a certain user was making the action. apparently it was from a trigger that was using a user which was long deleted (db was restored from an older version) so in case you are puzzled as i were, take a look at your db events/triggers/routines. hope this will help someone.
One or several of your views where created/registered by another user. You'll have to check the owner of the view and:
'web2vi'
using ALTER VIEWI had this problem once.
I was trying to migrate views, from BD1 to BD2, using SQLYog. SQLYog recreated the views in the other DataBase (DB2), but it kept the user of BD1 (they where different). Later I realized that the views I was using in my query were having the same error as you, even when I wasn't creating any view.
Hope this help.
The problem is clear - MySQL cannot find user specified as the definer.
I encountered this problem after synchronizing database model from development server, applying it to localhost, making changes to the model and then reapplying it to localhost. Apparently there was a view (I modified) defined and so I couldn't update my local version.
How to fix (easily):
Note: it involves deleting so it works just fine for views but make sure you have data backed-up if you try this on tables.
P.S. This is neither a proper nor best-all-around fix. I just posted it as a possible (and very simple) solution.
The user 'web2vi' does not exist on your mysql server.
See http://dev.mysql.com/doc/refman/5.1/en/error-messages-server.html#error_er_no_such_user
If that user does exist, check what servers it can access from, although I would have thought that would be a different error (EG you might have web2vi@localhost, but you are accessing the db as web2vi@% (At anything)
From MySQL reference of CREATE VIEW
:
The DEFINER and SQL SECURITY clauses specify the security context to be used when checking access privileges at view invocation time.
This user must exist and is always better to use 'localhost' as hostname. So I think that if you check that the user exists and change it to 'localhost' on create view you won't have this error.
// update all or particular procedures to your wanted, use existing user (my case -root)
1)
UPDATE mysql.proc p SET definer = 'root@%' WHERE 1=1 LIMIT 1000;
(limit clause is for the reason that various mysql versions complains when is updated not restricted with limit or no where condition is used)
2)
FLUSH PRIVILEGES; // or restart the server
The user who originally created the SQL view or procedure has been deleted. If you recreate that user, it should address your error.
You can try this:
$ mysql -u root -p
> grant all privileges on *.* to `root`@`%` identified by 'password';
> flush privileges;
when mysql.proc is empty, but system always notice "[email protected].%" for table_name no exist,you just root in mysql command line and type:
CHECK TABLE `database`.`table_name` QUICK FAST MEDIUM CHANGED;
flush privileges;
over!
Create the deleted user like this :
mysql> create user 'web2vi';
or
mysql> create user 'web2vi'@'%';
Try to set your procedure as
SECURITY INVOKER
Mysql default sets procedures security as "DEFINER" (CREATOR OF).. you must set the security to the "invoker".
Your view, "view_quotes" may have been copied from a different database where "web2vi" is a valid user into a database where "web2vi" is not a valid user.
Either add the "web2vi" user to the database or alter the view (normally removing the DEFINER='web2vi'@'%' part and executing the script will do the trick)
In my case, deleting all the views solved the issue.
DROP VIEW view_name;
If this is a stored procedure, you can do:
UPDATE `mysql`.`proc` SET definer = 'YournewDefiner' WHERE definer='OldDefinerShownBefore'
But this is not advised.
For me, better solution is to create the definer:
create user 'myuser' identified by 'mypass';
grant all on `mytable`.* to 'myuser' identified by 'mypass';
Try this This is simple solution
mysql -u root -p
SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
Fixed by running this following comments.
grant all on *.* to 'web2vi'@'%' identified by 'root' with grant option;
FLUSH PRIVILEGES;
if you are getting some_other
instead of web2vi
then you have to change the name accordingly.
I had the same problem with root user ans it worked for me when I replaced
root@%
by
root@localhost
So, if the user 'web2vi' is allowed to connect from 'localhost', you can try:
web2vi@localhost
I'm connected remotely to the database.
grant all on *.* to 'username'@'%' identified by 'password' with grant option;
example:
grant all on *.* to 'web2vi'@'%' identified by 'password' with grant option;
