I am newbie to mongodb.
We can execute list of queries by specifying it in a script .sql file in relational db and can run it by running the command source c:\test.sql.
How can we do that in mongodb? how to store those commands in mongodb script and how to execute in mongodb?
You can do it with shell script. You can execute the commands using the following command.
./mongo server:27017/dbname --quiet my_commands.js
For details check Scripting the shell document in Mongo docs.
