I’m a newbie to Liquibase, a lot of it already works wonderfully, but some things I still have to learn.

This is my changelog:

- changeSet:  
id: sqlldr  
author: swa0001  
runAlways: true  
changes:  
- executeCommand:  
args:  
- arg:  
value: “%LIQUIBASE\_COMMAND\_PASSWORD%”  
- arg:  
value: \<? username from properties file?\>  
executable: sqlldr.bat  
rollback: empty

Is there a way to use values from the properties file as arguments?

Using Enviromentvariables works fine, see first argument, but how to extract

- username or password
- url

from the properties file.

Thanks  
Andreas
