Description

MySQL Error 1369 occurs when an `INSERT` or `UPDATE` operation on a view fails to satisfy the `WITH CHECK OPTION` clause defined for that view. This means the attempted data modification would result in a row that does not meet the filtering conditions specified in the view's `WHERE` clause, violating the view's defined scope.

Error Message

CHECK OPTION failed '%s.%s'

🔍

Known Causes

3 known causes

⚠️

Inserting Non-Conforming Data

An `INSERT` statement attempted to add a new row through the view that does not meet the criteria specified in the view's `WHERE` clause.

⚠️

Updating Data Out of View Scope

An `UPDATE` statement modified an existing row through the view, causing it to no longer satisfy the conditions defined in the view's `WHERE` clause.

⚠️

Misunderstanding View Logic

The user or application performing the operation may not fully understand the filtering conditions or the purpose of the `WITH CHECK OPTION` clause on the view.

Solutions

3 solutions available

1. Satisfy the View's CHECK OPTION Clause easy

Ensure that the data being inserted or updated into the base table through the view meets the conditions defined in the view's CHECK OPTION clause.

1

Identify the view that is failing the CHECK OPTION. The error message '%s.%s' typically provides the database and view name. Let's assume the view is `my_database.my_view`.

SELECT TABLE_NAME FROM INFORMATION_SCHEMA.VIEWS WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_view';

2

Examine the `CHECK OPTION` clause of the view definition. You can get this by running: `SHOW CREATE VIEW my_database.my_view;`

SHOW CREATE VIEW my_database.my_view;

3

Understand the conditions specified in the `CHECK OPTION`. For example, if the view is `CREATE VIEW my_view AS SELECT * FROM my_table WHERE column1 > 10 WITH CHECK OPTION;`, then any INSERT or UPDATE operation through `my_view` must ensure `column1` is greater than 10.

CREATE VIEW my_view AS SELECT column1, column2 FROM my_table WHERE column1 > 10 WITH CHECK OPTION;

4

When performing an `INSERT` or `UPDATE` operation through the view, ensure the values provided satisfy these conditions. For instance, if you are inserting into `my_view` and the condition is `column1 > 10`, provide a value for `column1` that is greater than 10.

INSERT INTO my_view (column1, column2) VALUES (15, 'some_value'); -- This should succeed if column1 > 10 is the check
UPDATE my_view SET column1 = 20 WHERE id = 5; -- This should succeed if column1 > 10 is the check

5

If the operation is failing, it means the provided data does not meet the view's criteria. Adjust your `INSERT` or `UPDATE` statement to provide data that conforms to the `CHECK OPTION`.

-- Example of a failing INSERT:
INSERT INTO my_view (column1, column2) VALUES (5, 'another_value'); -- This will fail if column1 > 10 is the check

2. Modify the View Definition to Relax or Remove CHECK OPTION medium

Alter the view to remove the `WITH CHECK OPTION` clause or adjust the `WHERE` clause to be less restrictive.

1

Identify the view causing the issue and its current definition using `SHOW CREATE VIEW`.

SHOW CREATE VIEW my_database.my_view;

2

If the `CHECK OPTION` is too restrictive for your current use case, you can remove it by redefining the view. **Caution:** This will allow data that previously would have been rejected by the view's filter to be inserted/updated in the base table through the view.

CREATE OR REPLACE VIEW my_database.my_view AS
SELECT column1, column2
FROM my_table
WHERE column1 > 10; -- Removed 'WITH CHECK OPTION'

3

Alternatively, if you want to keep a `CHECK OPTION` but make it less restrictive, modify the `WHERE` clause accordingly. For instance, if you want to allow values >= 10 instead of > 10.

CREATE OR REPLACE VIEW my_database.my_view AS
SELECT column1, column2
FROM my_table
WHERE column1 >= 10
WITH CHECK OPTION; -- Modified WHERE clause

4

After redefining the view, any subsequent `INSERT` or `UPDATE` operations through this view will now adhere to the new definition. Test your operations to confirm.

INSERT INTO my_database.my_view (column1, column2) VALUES (10, 'new_value'); -- This will now succeed

3. Perform Operations Directly on the Base Table easy

Bypass the view and perform `INSERT` or `UPDATE` operations directly on the underlying table.

1

Identify the base table on which the view is defined. You can find this by examining the `SHOW CREATE VIEW` output.

SHOW CREATE VIEW my_database.my_view;

2

If the `CHECK OPTION` is causing issues and you don't want to modify the view, you can perform DML operations directly on the base table. This bypasses the view's `CHECK OPTION` entirely.

INSERT INTO my_table (column1, column2) VALUES (5, 'value_that_fails_view_check'); -- Inserting directly into base table

3

Similarly, for updates:

UPDATE my_table SET column1 = 5 WHERE id = 10; -- Updating directly in base table

4

Be aware that this approach means the data in the base table might not conform to the intended filtering logic of the view, which could lead to unexpected results when querying the view later. Ensure you understand the implications for your application's data integrity.

SELECT * FROM my_database.my_view WHERE id = 10; -- This row might not appear in the view if column1 is not > 10
