Unknown column 'metabase_field.special_type' in 'field list'

Hi after I upgrade 0.38.1 to 0.38.3, table valued functions and stored procedures can work normally, but simple queries have such problems

Hi @zqycn
It looks like you upgraded to 0.39.0-rc1 and then downgraded. You should revert to your backup.

Thank you. I downloaded the latest source code version, and then compiled and uploaded it. After uploading it, I found that some problems couldn't be used. Then I downloaded a compiled version, and then there was such a problem. I now restore the backup, free to test the next source version

Whoops! I didn't take a backup (lesson learned). Is there a dont-have-to-redo-everything way to get the dashboards up? BTW, I can't even get the UI to show up so I can't log in and go to Admin either.

@batman Sounds like you're seeing a different problem. Everything should work except making queries (and likely anything in Data Model).

I have no idea which application database you're using, but you would have to rename metabase_field.semantic_type to metabase_field.special_type, then it would work on pre-39 again.

But if you then upgrade to 39+ again, then you would manually need to change that back again.

Manually messing around in the application database is a great way to corrupt it, so you are warned and should of course make backups before making such a manual change - just like backing up before upgrading is strongly recommended.

@flamber Confirmed resolved and now the metabase instance is back up and running. I just copied the DB (we are using MySQL) to try 39 again. Will let you know if I see something worth reporting. The only thing I see now is that Unknown or incorrect time zone: 'US/Eastern' which seems to be related to the instance's timezone setting. I will check and update here.


@batman You need to load timezone into MySQL - it doesn't come with tzdata:
But that should not be a new thing on any recent versions - it's always been like that.

We have the timezone loaded into our MySQL servers. And this is the first time I am seeing this message. Interestingly, out other instances (two) of Metabase that use the same MySQL server don't report this. But given it's a warning, I am not losing sleep on it today. I will check this over the weekend.
