The target table for UPDATE is not updatable
Production Risk
Low — statement fails; no data changed.
What this means
An UPDATE or DELETE was issued against a view that is not updatable because it contains aggregation, DISTINCT, GROUP BY, UNION, or other constructs that prevent row-level mapping back to the base table.
Why it happens
- 1Updating a view defined with GROUP BY, DISTINCT, aggregate functions, or UNION
- 2View joins multiple tables and the row cannot be uniquely mapped to one base table row
How to reproduce
trigger — this will error
trigger — this will error
UPDATE (SELECT MAX(salary) AS ms FROM employees) tmp SET ms = 100000;
expected output
ERROR 1288 (HY000): The target table tmp of the UPDATE is not updatable
Fix
Update the base table directly
Update the base table directly
UPDATE employees SET salary = 100000 WHERE id = 1;
Why this works
Bypass the view and operate on the underlying table.
