-- 以省市表为例,主键自增
CREATE TABLE [nis_provinces] (
[id] [int] IDENTITY (1, 1) NOT NULL , [provinces] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL , [fatherid] [int] NOT NULL , CONSTRAINT [PK_nis_provinces] PRIMARY KEY CLUSTERED ( [id] ) ON [PRIMARY] ) ON [PRIMARY] GOinsert into nis_provinces values('北京市',0);
想插入北京各区数据,在oracle中,可以这样写:
insert into nis_provinces values('东城区',select id from nis_provinces where provinces='北京市') ;
但在sql server的insert语句中,不能使用子查询,要写成这样:
insert into nis_provinces select '东城区',id from nis_provinces where provinces='北京市'; insert into nis_provinces select '西城区',id from nis_provinces where provinces='北京市'; 相关阅读 更多 +
