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

[Xi Shen]

Hi,

http://orgmode.org/manual/var.html

This wiki explains how to use variable inside a src block. But I wonder if it is possible to specify variable to the variables in the src definition.

E.g. for the sql src block, I want to execute a script on different server. I want to define a variable for the ":dbhost" variable.

Regards,

David
