MySQL throws Error 1356 when it executes a view whose definition references tables, columns, or routines that no longer exist or cannot be accessed by the view definer. The server marks the view as invalid and returns SQLSTATE HY000.
The error appears during SELECT, INSERT, UPDATE, DELETE, SHOW CREATE VIEW, replication events, and even mysqldump operations that touch the invalid view. It often surfaces after schema refactoring, privilege changes, or database restores.
Invalid views break application features, dashboards, and ETL jobs. Allowing the issue to persist can cascade into data inconsistencies, runtime failures, and user-visible outages.
Dropping or renaming underlying tables, columns, or routines invalidates the view definition. Revoking privileges from the view definer also triggers the error. Migration mismatches between environments are another driver.
Identify missing objects or missing privileges, recreate or alter the view with valid references, or grant required rights. Testing in a staging environment prevents production surprises.
After renaming a column, update the view definition with ALTER VIEW or CREATE OR REPLACE VIEW. Post-restore, check that DEFINER accounts exist and have adequate permissions.
Use CREATE OR REPLACE VIEW in migrations, keep views in version control, and run automated tests that compile views after every schema change.
Errors 1146 (ER_NO_SUCH_TABLE) and 1109 (ER_UNKNOWN_FIELD) often accompany invalid views. Fixing the underlying object references resolves them together.
A DROP TABLE statement removed a table referenced by the view, making the view invalid.
Altering a column name or deleting it breaks select lists in the view definition.
Revoking SELECT or EXECUTE rights from the DEFINER account prevents the view from accessing referenced objects.
The view calls a stored function or procedure whose parameter list was modified, causing a mismatch.
Raised when a referenced table does not exist, often preceding ER_VIEW_INVALID.
Occurs when a column in the view definition is missing from the table.
Triggered when the definer account specified in a view or trigger no longer exists.
Views store no data, so recreating them does not delete rows. Only the definition is replaced.
You can switch to SQL SECURITY INVOKER to run the view with the invoker's privileges, but ensure users have adequate rights.
Query information_schema.views and attempt SELECT 1 FROM view_name in a loop, or use tools like mysqlcheck.
