DELETE 语句
DELETE 语句用于删除表中的行。
语法
DELETE FROM 表名称 WHERE 列名称 = 值
Person:
LastName FirstName Address City
Gates Bill Xuanwumen 10 Beijing
Wilson Fred Zhongshan 23 Nanjing
删除某行
"Fred Wilson" 会被删除:
DELETE FROM Person WHERE LastName = 'Wilson'
结果:
LastName FirstName Address City
Gates Bill Xuanwumen 10 Beijing
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
