Upgrade process (batch) doesn't provide a useful error message

Hi,

Testing the upgrade process, it's likely the start db was in bad shape, because I got error messages.

On the old upgrade, I got errors that where useful (exactly what command was in error), so we could manually fix/inspect)

Now, we only have 'No such field' and that's it, don't know which field or the table, don't know how to debug.

Would save a lot of problems to display back the complete sql in error
