WITH CHECK OPTION violation

What this means

SQLSTATE 44000 is raised when an INSERT or UPDATE through a view violates the WITH CHECK OPTION constraint — the row being written would not be visible through the view after the operation.

Why it happens
  1. 1INSERT into a view with WITH CHECK OPTION where the new row does not satisfy the view filter
  2. 2UPDATE through a view with WITH CHECK OPTION that moves the row out of the view visible set
How to reproduce

INSERT through a view with CHECK OPTION.

trigger — this will error
trigger — this will error
CREATE VIEW active_employees AS
  SELECT * FROM employees WHERE status = 'active'
  WITH CHECK OPTION;

INSERT INTO active_employees (name, status)
VALUES ('Bob', 'inactive'); -- violates CHECK OPTION

expected output

ERROR:  new row violates check option for view "active_employees"

Fix 1

Ensure inserted/updated rows satisfy the view filter

WHEN When writing through a view with CHECK OPTION.

Ensure inserted/updated rows satisfy the view filter
INSERT INTO active_employees (name, status)
VALUES ('Bob', 'active'); -- satisfies status = 'active' filter

Why this works

The row must satisfy the view WHERE condition after the write. With CHECK OPTION prevents writing rows that would be invisible through the view.

Fix 2

Remove WITH CHECK OPTION if filtering is not required

WHEN When the view is used for access control but check filtering is not needed.

Remove WITH CHECK OPTION if filtering is not required
CREATE OR REPLACE VIEW active_employees AS
  SELECT * FROM employees WHERE status = 'active';
  -- no WITH CHECK OPTION

Why this works

Without CHECK OPTION, inserts and updates through the view are not validated against the view filter.
