Connect to SQl Server from command prompt

If you find yourself needing to connect to an instance of SQL Server without Sequel Server Management Studio installed you can connect via command Prompt.

To connect using SQL authentication you need to use the following command:

sqlcmd /S /d -U -P

/S = the servername/instance name. Example:

/d = the database name. Example: DB1

-E = Windows authentication.

-U = SQL Server authentication/user. Example: darrenwelch

-P = password that belongs to the user. Example: 123456789


sqlcmd /S /d DB1 -U darrenwelch -P 12345678 


Once connected you can type your query & press enter, then type go and press enter. This will display your results.:

select * from table
