Q:

How to run .sql file from a batch file?

I am running sql server 2008 express and i need to schedule some stored procedures to run nightly...so i have built out these .sql files which i would want to run from .bat file...i need to know the command to execute these .sql files one by one and store their results i guess...can anyone help me out?

A:

I answered this in this other question:
You should invoke the sqlcmd command-line tool from your batch file. Assuming your sql file is "backup.sql", the command line would be something like:
sqlcmd -E -S yoursqlinstance -i backup.sql

-E uses trusted connection, replace with -U and -P if you need to specify a SQL username and password. See also this article with examples.

A:

See the sqlcmd utility:

This allows you to run sql scripts from the command line
