Modify the SQL Server sa password using the command line

I have always used the Enterprise Manager to operate SQL. Yesterday I helped a friend deploy a website and rented a foreign VPs host. After logging on, I only saw the SQL icon running normally, the Enterprise Manager and the query analyzer do not have any images. Sweat is one... The space provider does not provide technical support, and is dizzy. It is only necessary to find a solution.

Today, Google is done.

In the CMD window

C: \ Documents ents and Settings \ Administrator> osql-e

1> sp_password null, 'abc123', 'sa'

2> go

Password Changed.
1> exit

As a result, the SA password is changed to ABC123.

The key is osql this stuff, specific view http://msdn.microsoft.com/zh-cn/vstudio/ms162806.aspx
