How to delete rows with empty fields in SQL?

To delete rows with empty fields, you can use the DELETE statement combined with a NULL condition. Here is an example:

DELETE FROM 表名 WHERE 字段名 IS NULL;

The table name refers to the name of the table that needs to be operated on, while the field name refers to the name of the field that needs to be deleted or set to null.

Before executing the delete operation, ensure that you have backed up the data to prevent accidental deletion.
