Error Code: 1175
You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column

Every found that kind of error when trying to update rows in mysql? It’s because you tried to update a table without a WHERE that uses a KEY column (err …).
Anyway, The quick fix is to add SET SQL_SAFE_UPDATES=0; before your update query. Here’s the example:

SET SQL_SAFE_UPDATES=0;
DELETE FROM people WHERE person_status = 'deceased';
