I don't use views or routines, so the "algorithm" is not aware about It.When there are many real changes between the model and the bd, I recommend fix 2 or 3 tables on the same time, and set as "Ignore" all other changes detected by Workbench and and re-run above algorithm until your fix all tables.If everything was fine as you already checked, your model diagrams should be intact: see mainly for any relationship change. Do that selecting all changes in the screen and then pressing the button "Update Model".

For this scenario, first check the db exactly have same indexes and foreign keys as model has (I normally do it for 2 or 3 tables) then run the tool and update model instead db.

However there is still some indexes and foreign keys synchronization issues.

At this point, all change and drop commands over a table or a table's field should be fixed.

You can figure out if you will write by hand the update sql code then is pointless use the Synchronization tool and read this answer, although if you edit the generated code to the right one inside this wizard screen, the model "magically" get correctly synchronized. So I manually edit the generated sql to update the bd.

Sometimes, the previous steps does not fix the problems.

This sometimes works, and the generated sql code change from a "DROP" to a "CHANGE" when a table's field is updated in the model.Īt the "Preview Database Changes to be Applied" screen:

I had faced the same problem with MySQLWorkbench. If you are sure your db is identical to your model, you can update your model instead your db. But on my test database after totally getting wiped out and trying it again, the Differences page shows up normally with everything 1:1 like it should, and it updated just fine. I have no idea if this is some kind of setting or bug. Here is the picture of what the page looks like. If I run the update as it is my database does get updated, but it also completely wipes out all the information on the database because it is dropping all the tables and re-entering them.

Then below that it has all of the Source values filled in while the Model values all say N/A. I get everything doubled with the first set showing the Model names of my Schema and Tables with the Sources next to all of them showing N/A. The problem is when it gets to the point where it shows "Model and Database Differences", the fields which all normally line up between Model and Source are totally off. Main thing to note here is that the issue I'm going to describe happens even without any changes being made to the model. I am using the Synchronize Model option just as I have always done before to update the database with the changes I've made to the model. I am trying to update my MySQL database using MySQL Workbench (5.2.40 CE). I've been looking all over for any description of an issue like this and I haven't found anything so far.
