Of course it does not work. Use SMO to get a list of servers.

SMO works for all versions of SQL Server from 2005 on. So it does work. Why you think it does not, is a mystery.

Read this : http://sqlblogcasts.com/blogs/jonsayce/archive/2008/02/10/programatically-listing-sql-servers.aspx[^]

Generally database server names to connect to are a known configuration point when you deploy your application, and for security reasons the above way may not work (you don't want to advertise your database server for hackers etc.).

You can't! Why? You need to be connected to particular server to run sql command.

If you want to display the list of sql servers installed on local computer or on lan, please see: How to enum SQL Server instances in network[^]

If you want to check if SQL statement is correct, look for SQLParser[^].
