1.mysql delete tables in three ways

delete、drop、truncate。

Similarities and differences:

• delete and truncate table to delete only data, without deleting the table structure, truncate can not be retrieved (will release the space occupied by the table).
• drop delete the entire table, you can not be recovered.

2. Usage

• Not only can delete the drop table, you can also delete the database.

drop 表名/数据库名

• Truncate delete all the data in the table, but can not be used with where

truncate 表名;

• delete can be used in conjunction with the where, delete particular row

#删除表中所有数据
delete from 表名;

#删除符合条件的表数据
delete from 表名 where 字段名=条件;

Speed, the general drop> truncate> delete
