I have a person table in SQL and i have columns: id, lastname, firstname, address, city.
City for a person is empty so i want a query to delete the row containing the person with a blank city column value. The code below didn’t do it even though no errors were raised.
DELETE FROM persons pers
WHERE lastname = 'saire' AND address = 'NULL'
The following SQL command should remove all records with a null value for city. Try this.
