    initial v1  
    1 Actually there could be a different problem as well. We were lucky in that the ORM generated SQL where the column types do not match. But what happens when the column types match? I'm afraid you would get a query that doesn't throw an exception but is in fact subtly broken, especially if the values of the differnet columns happen to be similar, in which case it might take a long time for app developers to realize that the query is broken.
