Re: [O] Is it possible to pass variable to variables of src block?

[Xi Shen]

Hi Michael,

Yes, I think this is a way to my previous question. But what I really want to achieve is to loop through a list of server names and execute a script on them.

Say I have 20 different database server. How can I do a loop with each server?

Regards,

David

did you think about something like this?


(setq hmw/dbhost "db1")

#+BEGIN_SRC sql :dbhost (symbol-value 'hmw/dbhost) :dbuser weather :database environment :engine postgresql
select time, temperature from weather limit 20;
#+END_SRC
