Statement: Delete from dbo.blog.category where cate_id = 21, this statement can delete all the data under the column id=21, after execution, found that 6,504 data has been successfully deleted.
Visible, knowledge is power, through a simple answer to learn, we found that can be completed in batches so much content, the importance of learning, any time learning knowledge is useful, is not too late, live to learn old!
