feature request #4580

Updated by Andreas Müller almost 7 years ago

~~Schema Schema Updater should return a Result instead of pure boolean.~~ boolean.  


 Also we may want to register each successful step in the model version instead of updating only after full update script running. 


 Updates steps should be split into 

 * adding objects (column, tables, etc.) - no harm but also no transactions possible 

 * updating data - may run in a single transaction 

 * removing object - no real harm if not successful, step may run optionally, feedback for system administrator may be alternative solution
