Description

It would be great if DDLUtils had the ability to diff two schema XML files (source and target) and generate database-specific SQL that can be saved to a file? Ideally, I'd like to use for handling database upgrades of our product. The SQL output would be all the "alter table" type statements required to move from the source schema to the target.

This seems to be almost what the WriteSchemaToDatabase command is doing for a single schema and a live database with alterDatabase=true. Could we replace the live database with a second schema and then have the SQL sent to a file rather than to the live database.
