Hi everyone,

I would like to create separate xml-changelog files for every dbms we support. As it would be a redundant information I don’t want to specify the dbms for every changeset. Instead of it I would like to specify it as the databasechangeLog. I tried to use a precondition, but this doesn’t work as it stops the execution completely (HALT) or warns and executes the statements anyway (WARN).

Is it possible to add the dbms attribute for the databaseChangeLog as well?

Kind regards  
Oliver

We don’t currently support it, but it would be a good feature to add.&nbsp; It wouldn’t be something I could get to for the 2.0 release, but if you wanted to try to implement it and submit a patch I’d be happy to add it.&nbsp; Otherwise, create a feature request at [http://liquibase.jira.com](http://liquibase.jira.com) and I can add it to the list, possibly for 2.1.
