Known Causes

3 known causes

⚠️

Revoking Non-existent Grant

This occurs when an attempt is made to revoke a specific routine grant that has never been defined or was already removed for the specified user and host.

⚠️

Incorrect Grant Specification

The routine name, user, or host specified in a grant management statement might be misspelled or incorrect, leading to a lookup failure.

⚠️

Misunderstanding Privilege Scope

Users might expect grants to apply implicitly or through broader privileges, but routine execution often requires specific, explicit permissions.

Solutions

4 solutions available

1. Grant Routine Privileges to the User easy

Explicitly grant the necessary privileges for the user to execute the specified routine.

1

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

2

Execute the `GRANT` statement to provide the user with the `EXECUTE` privilege on the specific routine. Replace 'your_user', 'your_host', 'your_database', and 'your_routine' with the actual values from the error message.

GRANT EXECUTE ON FUNCTION your_database.your_routine TO 'your_user'@'your_host';
-- or for stored procedures:
GRANT EXECUTE ON PROCEDURE your_database.your_routine TO 'your_user'@'your_host';

3

Flush privileges to ensure the changes are loaded.

FLUSH PRIVILEGES;

2. Grant All Routine Privileges on a Database easy

Grant the user the ability to execute any routine within a specific database.

1

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

2

Execute the `GRANT` statement to provide the user with the `EXECUTE` privilege on all routines in a database. Replace 'your_user', 'your_host', and 'your_database' with the actual values.

GRANT EXECUTE ON your_database.* TO 'your_user'@'your_host';

3

Flush privileges to apply the changes.

FLUSH PRIVILEGES;

3. Grant All Privileges on the Database medium

Grant the user all possible privileges on a specific database, including routine execution.

1

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

2

Execute the `GRANT ALL PRIVILEGES` statement for the user on the database. This is a broader grant and should be used with caution. Replace 'your_user', 'your_host', and 'your_database'.

GRANT ALL PRIVILEGES ON your_database.* TO 'your_user'@'your_host';

3

Flush privileges to make the changes effective.

FLUSH PRIVILEGES;

4. Verify User and Hostname easy

Ensure the username and hostname used in the grant statements match the user attempting to access the routine.

1

Identify the exact username and hostname MariaDB is using when the error occurs. This is usually indicated in the error message itself (e.g., '%s' on host '%s').

2

Connect to MariaDB as a privileged user and check the existing grants for that user and host.

SHOW GRANTS FOR 'your_user'@'your_host';

3

If the grants do not include `EXECUTE` for the specific routine or database, use one of the previous solutions to grant the necessary privileges.
