sqlcmd -S servername\instancename -i D:\yoursqlscript.sql

if you are getting an error – “Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Login failed for user ‘servername\instancename'” after executing above command. Don’t worry you can simply overcome this error by providing username and password which you have provided for authentication for SQL SERVER.  You can use below command

sqlcmd -S servername\instancename  -U sa -P YourSQLServerPassword -i D:\yoursqlscript.sql

Note:-  There parameter “U, -P, i” are case sensitive parameter. Do not use -U and -P as a small letter as -u, -p and i as -I because the sqlcmd utility has reserver function for that particular parameter.

  • -U  (for login id )
  • -P (for password)
