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
