Tracing all changes can be accomplished by other means, e.g. via recording all GraphDiffs before commit (GraphDiffs are the internal format Cayenne uses to store object changes, that are later transformed to SQL).

However I'd recommend investigating a DB-level backup solution, as a much more robust alternative. E.g. take a periodic production data dump, load it to the dev DB, then run some SQL script to make sure the data is appropriately massaged for the dev environment. This should work for the databases up to a certain size. Of course if you have terabytes of data, then it won't scale (or require a more fine grained approach to backup creation).

Hi Andrus, I did in fact forget about that.

I was looking for an easy way to recreate parts of the object network to transfer between stages of our application. E.g. create SQL for a data set to insert it in the development db for testing.

Re: how to get update/insert SQL without committing to db





Hi Tobias,

Could you elaborate a bit on how are you going to use this SQL? SQL
generated by Cayenne is in a PreparedStatement format, so it will not
be usable for say manual execution from a SQL client.
