SQLCMD Startup Script

SQLCMD can run a startup script defined by the environment variable SQLCMDINI.

Suppose you want to always execute the following query when you are connected to the server:

SELECT @@SERVERNAME, @@VERSION 

Place this command inside the init.sql file and define the following environment variable:

C:\SET SQLCMDINI=c:\sqlscripts\init.sql 

Then whenever you start a SQLCMD session, the script automatically executes and displays query output listing the server name and full version string.
