Known Causes

4 known causes

⚠️

Insufficient User Privileges

The database user attempting the operation has not been granted the required privileges (e.g., SELECT, INSERT, UPDATE, DELETE, CREATE) for the specific database, table, or operation.

⚠️

Incorrect User or Host

The user might be connecting with a different username or from a host that has fewer privileges than expected, or the user account itself is incorrectly specified.

⚠️

Newly Created User

A recently created user account might not have any specific privileges granted yet, or only default, very limited privileges, preventing most operations.

⚠️

Revoked Privileges

An administrator may have recently revoked specific privileges from the user account, or the privileges expired, leading to unexpected access denial.

Solutions

3 solutions available

1. Grant Specific Privileges to the User medium

Grant the minimal necessary privileges to the user for the operation they are trying to perform.

1

Connect to your MariaDB server as a user with sufficient administrative privileges (e.g., root).

mysql -u root -p

2

Identify the operation causing the error and the required privilege. The error message usually indicates this (e.g., 'SELECT', 'INSERT', 'UPDATE', 'DELETE', 'CREATE', 'ALTER', 'DROP').

Access denied; you need (at least one of) the SELECT privilege(s) for this operation

3

Grant the specific privilege to the user on the relevant database or table. Replace 'your_user', 'your_database', and 'your_table' with actual values. If the privilege is needed for all databases, omit 'your_database.'.

GRANT SELECT ON your_database.your_table TO 'your_user'@'localhost';
-- Or for all databases:
-- GRANT SELECT ON *.* TO 'your_user'@'localhost';

4

Apply the privilege changes.

FLUSH PRIVILEGES;

5

Have the user try the operation again.

2. Grant All Privileges on a Specific Database easy

Grant all privileges on a particular database to the user, useful for application users.

1

Connect to your MariaDB server as a user with administrative privileges.

mysql -u root -p

2

Grant all privileges on the specified database to the user. Replace 'your_user', 'your_database', and 'localhost' with your actual values.

GRANT ALL PRIVILEGES ON your_database.* TO 'your_user'@'localhost';
-- If the user connects from any host, use '%' instead of 'localhost':
-- GRANT ALL PRIVILEGES ON your_database.* TO 'your_user'@'%';

3

Reload the grant tables to make the changes effective.

FLUSH PRIVILEGES;

4

Ask the user to attempt the operation again.

3. Review and Correct User Host Specification medium

Ensure the user account being used has the correct host specification matching where they are connecting from.

1

Connect to your MariaDB server as a privileged user.

mysql -u root -p

2

Check the existing user accounts and their host specifications.

SELECT user, host FROM mysql.user;

3

If the user is connecting from a different host than what is defined in 'mysql.user', you may need to update the user's host or create a new user entry for that host.

-- Example: Updating host for an existing user:
-- ALTER USER 'your_user'@'old_host' IDENTIFIED BY 'password' RENAME TO 'your_user'@'new_host';

-- Example: Creating a new user for a different host (if the user already exists but not for this host):
-- GRANT USAGE ON *.* TO 'your_user'@'new_host' IDENTIFIED BY 'password';
-- GRANT SELECT ON your_database.your_table TO 'your_user'@'new_host';

4

Reload the grant tables.

FLUSH PRIVILEGES;

5

Ask the user to try connecting and performing the operation again.
