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复制代码 代码如下: 

 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
