MySQL Error 1345: Lacking Privileges for View Analysis
Description
This error occurs when attempting to use `EXPLAIN` or `SHOW` on a MySQL view. It indicates that the current user account does not possess the necessary privileges on one or more of the underlying base tables that the view references. While the user might have access to query the view itself, inspecting its execution plan or definition requires direct access permissions to its source tables.
Error Message
EXPLAIN/SHOW can not be issued; lacking privileges for underlying table
Known Causes
3 known causesInsufficient Base Table Privileges
The user account attempting the `EXPLAIN` or `SHOW` operation lacks `SELECT` or other required privileges on the actual tables that compose the view.
`SQL SECURITY DEFINER` View Context
If the view was created with `SQL SECURITY DEFINER`, the operation runs with the definer's privileges, but the current user still requires direct access to inspect the underlying structure.
Indirect Access Restriction
Even with `SELECT` permission on the view, `EXPLAIN` and `SHOW CREATE VIEW` operations often demand direct privilege on the underlying tables, which may not be granted.
Solutions
4 solutions available1. Grant Necessary Privileges to the User easy
Provide the user with SELECT privileges on the tables used by the view.
1
Connect to your MySQL server as a user with sufficient privileges (e.g., root).
2
Identify the tables that the problematic view is based upon. You can usually find this information by inspecting the view's definition.
SHOW CREATE VIEW view_name;3
Grant the SELECT privilege on those underlying tables to the user encountering the error.
GRANT SELECT ON database_name.table_name TO 'user_name'@'host_name';4
If the view spans multiple tables, repeat the GRANT command for each table.
5
Flush privileges to ensure the changes take effect immediately.
FLUSH PRIVILEGES;6
Have the user try the EXPLAIN or SHOW command again.
2. Grant SHOW VIEW Privilege for the View easy
Allow the user to see the definition of the view itself.
1
Connect to your MySQL server as a user with sufficient privileges (e.g., root).
2
Grant the SHOW VIEW privilege on the specific view to the user.
GRANT SHOW VIEW ON database_name.view_name TO 'user_name'@'host_name';3
Flush privileges.
FLUSH PRIVILEGES;4
Have the user attempt the EXPLAIN or SHOW command again.
3. Grant Global Privileges (Use with Caution) medium
Grant broader privileges to the user if specific table/view grants are not feasible or the user needs access to many objects.
1
Connect to your MySQL server as a user with sufficient privileges (e.g., root).
2
Grant the user the SELECT privilege on all tables within the database.
GRANT SELECT ON database_name.* TO 'user_name'@'host_name';3
Optionally, grant SHOW VIEW privilege on all views in the database.
GRANT SHOW VIEW ON database_name.* TO 'user_name'@'host_name';4
Alternatively, for broader access (use with extreme caution as it grants many permissions), grant global SELECT privilege. This might be too broad for production environments.
GRANT SELECT ON *.* TO 'user_name'@'host_name';5
Flush privileges.
FLUSH PRIVILEGES;6
Have the user try the EXPLAIN or SHOW command again.
4. Recreate the View with Appropriate Permissions medium
If the view was created by a user with insufficient privileges, recreate it with a user who has them, or grant the necessary permissions during creation.
1
Connect to your MySQL server as a user with sufficient privileges (e.g., root) and the ability to create views.
2
Drop the existing view.
DROP VIEW IF EXISTS view_name;3
Create the view again using the same definition, ensuring the user creating it has all necessary underlying table privileges.
CREATE VIEW view_name AS SELECT column1, column2 FROM table1 JOIN table2 ON table1.id = table2.id WHERE condition;4
After recreating the view, grant the necessary privileges to the user who was originally encountering the error.
GRANT SELECT ON database_name.table_name TO 'user_name'@'host_name';
GRANT SHOW VIEW ON database_name.view_name TO 'user_name'@'host_name';5
Flush privileges.
FLUSH PRIVILEGES;
