Question
You have a table named pamperedPets. The table tracks the pets of customers by pet_id. There is a record for a pet whose pet_id is 10. You need to change the value of the age field from 7 to 8. You open MySQL Workbench and begin typing your query:UPDATE pamperedPets SET age = 8WHERE pet_id = 10;You execute the statement. You then execute a SELECT statement and discover that the record has not been updated. What must you do to update the table?1 pointChange the query to UPDATE pamperedPets WHERE pet_id=10 SET age=8Change the query to UPDATE pamperedPets SET age=8 WHERE pet_id IN (SELECT pet_id FROM pamperedPets WHERE pet_id=10)Change the query to UPDATE pamperedPets SET age=8You should execute the SET SQL_SAFE_UPDATES=0 statement.
Solution
To update the table, you should execute the SET SQL_SAFE_UPDATES=0 statement. This is because MySQL Workbench has a feature called 'Safe Updates' that prevents UPDATE and DELETE statements from being executed unless there is a key constraint in the WHERE clause. By setting SQL_SAFE_UPDATES to 0, you disable this feature and allow your UPDATE statement to execute. After executing SET SQL_SAFE_UPDATES=0, you can then run your original UPDATE statement again.
