SQL-DELETE

DELETE语句

DELETE语句用于删除表中的行。

语法:

DELETE FROM table_name WHERE column_name = value

举例

Person:

LastName FirstName Address City
Gates Bill Xuanwumen 10 Beijing
Wilson Fred Zhongshan 23 Nanjing

DELETE FROM Persons WHERE LastName=‘Wilson‘

删除所有行

可以在不删除表的情况下删除所有的行。这意味着表的结构、属性和索引都是完整的:

DELETE FROM table_name

或者

DELETE * FROM table_name
