MariaDB Error 1143: Column Access Denied
Description
This error indicates that a specific database user attempted to execute a command (e.g., SELECT, INSERT, UPDATE) on a particular column within a table, but their assigned privileges do not permit this action. It typically arises when user permissions are too restrictive or incorrectly configured for column-level operations.
Error Message
%s command denied to user '%s'@'%s' for column '%s' in table '%s'
Known Causes
4 known causesInsufficient Column-Level Privileges
The user account lacks specific GRANT privileges (e.g., SELECT, UPDATE) for the target column in the specified table.
Incorrect User or Host
The user account attempting the operation is not the one expected, or the connection is from an unprivileged host, leading to a privilege mismatch.
Misconfigured Default Privileges
New users or roles might inherit default privileges that are too restrictive, preventing column-level access even if table-level access exists.
Privilege Cache Not Refreshed
Recent privilege changes might not have been reloaded by the MariaDB server, causing old, restrictive permissions to still be enforced.
Solutions
4 solutions available1. Grant Specific Column Privileges easy
Grant the user explicit permission to access the problematic column.
1
Connect to your MariaDB server as a user with sufficient privileges (e.g., root).
2
Execute the `GRANT` statement to allow the user access to the specific column. Replace placeholders with your actual values.
GRANT SELECT (column_name) ON database_name.table_name TO 'user_name'@'host_name';3
If the user needs to perform other operations (INSERT, UPDATE, DELETE) on that column, adjust the `GRANT` statement accordingly. For example, to grant UPDATE access:
GRANT UPDATE (column_name) ON database_name.table_name TO 'user_name'@'host_name';4
Flush privileges to ensure the changes take effect immediately.
FLUSH PRIVILEGES;2. Grant All Privileges on the Table easy
Grant the user all necessary privileges on the entire table, effectively bypassing the column-level restriction.
1
Connect to your MariaDB server as a user with sufficient privileges (e.g., root).
2
Execute the `GRANT` statement to give the user all privileges on the table. Replace placeholders with your actual values.
GRANT ALL PRIVILEGES ON database_name.table_name TO 'user_name'@'host_name';3
Flush privileges to apply the changes.
FLUSH PRIVILEGES;3. Review and Modify User Privileges medium
Inspect the user's existing privileges and update them to include the required column access.
1
Connect to your MariaDB server as a user with administrative privileges.
2
View the current privileges for the affected user.
SHOW GRANTS FOR 'user_name'@'host_name';3
Analyze the output to understand what privileges the user currently has. Identify if the problematic column is explicitly excluded or if a broader restriction is in place.
4
Based on the analysis, either grant specific column privileges (Solution 1) or a broader table privilege (Solution 2). If the user has been granted specific column access but still faces this error, there might be a conflict or an oversight in the `GRANT` statements.
5
After making any necessary adjustments to the `GRANT` statements, flush privileges.
FLUSH PRIVILEGES;4. Grant All Privileges on the Database medium
Grant the user all privileges on the entire database, which implicitly includes all tables and columns.
1
Connect to your MariaDB server as a user with administrative privileges.
2
Execute the `GRANT` statement to provide all privileges on the database. Replace placeholders with your actual values.
GRANT ALL PRIVILEGES ON database_name.* TO 'user_name'@'host_name';3
Flush privileges to make the changes active.
