CMD命令操作MSSQL2005数据库

打开CMD命令

执行：sqlcmd/?

这是sqlcmd命令的一些帮助信息

通过上面可以知道怎么连数据库了

执行：sqlcmd -S 服务器地址 -d 数据库名称 -U 用户密码 -P 密码

以下是操作数据库的一下命令

0.  创建数据库

      CREATE DATABASE DB001

1.  创建用户

       CREATE LOGIN  USER1
WITH PASSWORD = 'USER_PW';

2. 修改数据的所有者

      USE DB001
exec sp_changedbowner 'USER1'

      GO

 3. 设置READ_COMMITTED_SNAPSHOT

     ALTER DATABASE [DB001] SET READ_COMMITTED_SNAPSHOT ON
GO

4.修改字符集

    ALTER DATABASE DB001  COLLATE SQL_Latin1_General_CP437_CS_AS 
GO

5. 获取所有数据库名:
Select Name FROM Master..SysDatabases

6 . 获取所有表名:
select name from sysobjects where type='U' 
XType='U':表示所有用户表;
XType='S':表示所有系统表;

7. 获取所有字段名:
Select Name from SysColumns Where id=Object_Id('TableName') 

8. 查看与某一个表相关的视图、存储过程、函数

      select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%TableName%'

9.  查询某一个表的字段和数据类型

    select column_name,data_type from information_schema.columns
where table_name = N'TableName'

10. 获取数据库文件路径

     select ltrim(rtrim(filename)) from   dbname ..sysfiles where charindex('MDF',filename)>0
or
select ltrim(rtrim(filename)) from dbname    ..sysfiles where charindex('LDF',filename)>0
