All data in the PHP MySQL delete table is kept only one

DELETE from ' logs ' WHERE wangzhi= ' www.juhutang.com ' and  id<>101072;

The above code means to delete all the fields in the table logs Wangzhi contains data with www.juhutang.com content. However, this data with ID 101072 in the same table is not deleted.

Of course, I am a novice, this statement may not be so perfect as the title,

I hope Daniel will answer, delete all the data in the table, keep the most recent one or only the one with the largest primary key ID. How this statement is written.
