Welcome to our channel,
mysql IS NULL : A field with a NULL value is a field with no value.
If a field in a table is optional, it is possible to insert a new record or update a record without adding a value to this field. Then, the field will be saved with a NULL value.
Watch this video and learn it easily.
Thank You.
