MariaDB Error 1356: View References Invalid Objects
Description
This error occurs when a MariaDB view cannot be created or executed because it refers to non-existent database objects (tables, columns, functions) or because the user lacks the necessary permissions to access those objects. It indicates a problem with the view's definition or the user's privileges, preventing the view from being valid or usable.
Error Message
View '%s.%s' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them
Known Causes
3 known causesMissing Referenced Objects
The tables, columns, or functions that the view attempts to access do not exist in the database, have been dropped, or are incorrectly spelled in the view definition.
Insufficient User Privileges
The database user attempting to create or query the view (definer or invoker) does not have the required `SELECT` or `EXECUTE` privileges on the underlying tables or functions referenced by the view.
Invalid or Inaccessible Functions
The view attempts to use a user-defined function (UDF) or stored procedure that is either non-existent, invalid, or for which the user lacks execution privileges.
Solutions
3 solutions available1. Verify and Recreate Dependent Objects medium
Check for missing or renamed tables/columns and recreate the view.
1
Identify the exact view and the objects it references. The error message usually provides the view name. You can also find this information by querying `information_schema.VIEWS`.
SELECT TABLE_NAME, COLUMN_NAME FROM information_schema.STATISTICS WHERE TABLE_SCHEMA = 'your_database_name' AND TABLE_NAME = 'your_view_name';2
Manually inspect the referenced tables and columns to ensure they exist and are spelled correctly. Check for any recent `DROP TABLE`, `ALTER TABLE` (especially renaming or dropping columns), or `DROP COLUMN` operations.
SHOW TABLES LIKE 'referenced_table_name';
DESCRIBE referenced_table_name;3
If a referenced object is missing or incorrect, recreate it or correct its name. If the view definition itself has an incorrect table or column name, correct it.
CREATE TABLE referenced_table_name (...);
-- or --
ALTER TABLE referenced_table_name ADD COLUMN new_column_name ...;
-- or --
ALTER TABLE referenced_table_name CHANGE old_column_name new_column_name ...;4
Once all referenced objects are confirmed to be valid and correctly named, drop and recreate the problematic view.
DROP VIEW IF EXISTS your_database_name.your_view_name;
CREATE VIEW your_database_name.your_view_name AS
SELECT ... FROM referenced_table_name WHERE ...;2. Check Definer and Invoker Privileges medium
Ensure the view's definer or invoker has permissions to access the referenced objects.
1
Determine the `DEFINER` and `SQL SECURITY` settings of the view. You can find this by querying `information_schema.VIEWS`.
SELECT DEFINER, SQL_SECURITY FROM information_schema.VIEWS WHERE TABLE_SCHEMA = 'your_database_name' AND TABLE_NAME = 'your_view_name';2
If `SQL SECURITY DEFINER` is used, verify that the user specified in `DEFINER` has the necessary `SELECT` privileges on all referenced tables and `EXECUTE` privileges on any referenced functions.
SHOW GRANTS FOR 'definer_user'@'host';
-- To grant privileges --
GRANT SELECT ON referenced_table_name TO 'definer_user'@'host';
GRANT EXECUTE ON FUNCTION referenced_function TO 'definer_user'@'host';3
If `SQL SECURITY INVOKER` is used, verify that the user *currently executing* the view has the necessary `SELECT` privileges on all referenced tables and `EXECUTE` privileges on any referenced functions.
SHOW GRANTS FOR CURRENT_USER();
-- To grant privileges --
GRANT SELECT ON referenced_table_name TO CURRENT_USER();
GRANT EXECUTE ON FUNCTION referenced_function TO CURRENT_USER();4
If privileges are missing, grant them to the appropriate user. After granting privileges, you might need to recreate the view for the changes to take effect, especially if the definer was the issue.
DROP VIEW IF EXISTS your_database_name.your_view_name;
CREATE VIEW your_database_name.your_view_name AS
SELECT ... FROM referenced_table_name WHERE ...;3. Address Invalid Functions or Procedures medium
Ensure any functions or procedures used within the view are valid and accessible.
1
Examine the view definition for any calls to stored functions or procedures. The error message might explicitly mention invalid functions.
SELECT VIEW_DEFINITION FROM information_schema.VIEWS WHERE TABLE_SCHEMA = 'your_database_name' AND TABLE_NAME = 'your_view_name';2
Verify that these functions/procedures exist in the database and are spelled correctly. Check their status.
SHOW FUNCTION STATUS WHERE Db = 'your_database_name' AND Name = 'your_function_name';
SHOW PROCEDURE STATUS WHERE Db = 'your_database_name' AND Name = 'your_procedure_name';3
If a function or procedure is missing, invalid, or has been altered in a way that breaks compatibility, recreate it. Ensure the definer/invoker of the view has `EXECUTE` privileges on these objects.
DROP FUNCTION IF EXISTS your_database_name.your_function_name;
CREATE FUNCTION your_database_name.your_function_name (...) RETURNS ... ...;
-- or --
DROP PROCEDURE IF EXISTS your_database_name.your_procedure_name;
CREATE PROCEDURE your_database_name.your_procedure_name (...) ...;4
After ensuring the function/procedure is valid and accessible, recreate the view.
DROP VIEW IF EXISTS your_database_name.your_view_name;
CREATE VIEW your_database_name.your_view_name AS
SELECT your_function_name(...) FROM ...;
