DELETE FROM table_name [WHERE Clause]
1. If the WHERE clause is not specified, then all the records will be deleted from the given MySQL table.
2. You can specify any condition using the WHERE clause.
3. You can delete records in a single table at a time.
The WHERE clause is very useful when you want to delete selected rows in a table.
