Just started to learn SQL, I can’t start using MS SQL Server. When I try to execute "sqlcmd" on the command line, I get:
HResult 0x2, Level 16, State 1 Named Pipes Provider: Could not open a connection to SQL Server . Sqlcmd: Error: Microsoft SQL Server Native Client 10.0: Error: It was a network connection. Server is not found or not accessible. Check if instance is correct and i f SQL Server is configured to allow remote connections. For more information see SQL Server Books Online ..
