Description

MySQL Error 1227 indicates that the user or client attempting to perform a specific database operation lacks the necessary privileges. This error commonly occurs when a user tries to execute a SQL statement (like SELECT, INSERT, UPDATE, CREATE, or DROP) for which they have not been granted permission on the target database, table, or other database object.

Known Causes

4 known causes

⚠️

Insufficient User Privileges

The MySQL user account attempting the operation does not possess the specific privileges required (e.g., SELECT, INSERT, UPDATE, DELETE) on the relevant database, table, or global scope.

⚠️

Incorrect User/Host Combination

The user account exists, but the connection is being made from a host that is not authorized for that specific user, or the user account is defined for a different host.

⚠️

Missing GRANT OPTION Privilege

If a user attempts to grant privileges to another user, they must possess the `GRANT OPTION` privilege themselves, which may be missing from their account.

⚠️

Object-Specific Permission Issues

The user might have general database access but lacks specific privileges required for operations on particular database objects, such as stored procedures, functions, or views.

Solutions

5 solutions available

1. Grant Required Privilege medium

Give user the specific privilege needed

1

Connect as admin/root

mysql -u root -p

2

Grant SUPER privilege (use carefully)

GRANT SUPER ON *.* TO 'username'@'localhost';
FLUSH PRIVILEGES;

3

Or grant specific privilege needed

-- For PROCESS (show processlist)
GRANT PROCESS ON *.* TO 'username'@'localhost';

-- For REPLICATION
GRANT REPLICATION CLIENT, REPLICATION SLAVE ON *.* TO 'username'@'localhost';

2. Use Different Approach easy

Avoid needing SUPER privilege

1

For SET GLOBAL - use config file instead

-- Instead of: SET GLOBAL variable = value;
-- Edit my.cnf and restart MySQL:
[mysqld]
variable = value

2

For KILL - check if you own the connection

-- You can kill your own connections without SUPER
-- First check it's yours:
SELECT * FROM information_schema.PROCESSLIST WHERE ID = 12345;

3. Contact DBA or Admin easy

Request privilege or action from administrator

1

Check what privilege you need

-- The error message usually says which privilege
-- Common operations requiring SUPER:
-- - SET GLOBAL
-- - KILL other users' connections
-- - Binary logging control
-- - Definer changes on triggers/procedures

4. Run with Sufficient Privileges easy

Connect as user with required privileges

1

For one-time admin tasks, use root

mysql -u root -p -e "SET GLOBAL max_connections = 200;"

5. MySQL 8.0+ Dynamic Privileges medium

Use fine-grained privileges instead of SUPER

1

Grant specific dynamic privileges

-- MySQL 8.0+ splits SUPER into granular privileges:

-- For SET GLOBAL on specific variables:
GRANT SYSTEM_VARIABLES_ADMIN ON *.* TO 'user'@'localhost';

-- For KILL:
GRANT CONNECTION_ADMIN ON *.* TO 'user'@'localhost';

-- For binary log operations:
GRANT BINLOG_ADMIN ON *.* TO 'user'@'localhost';
