> logic should be doing some type checking and verification before insert

There are a minority of coders who are actually anal enough to get that right 100% of the time in every version of every app that touches the database. But those are not the people who are reckless enough to want to omit types from the schema. If you think doing it the easy and reliable way isn't worth the hassle, you are not actually going to do it the hard way, even if you can convince yourself you will.

Dunno why you replied to me, but I agree. In single app usage, in a well controlled and well defined situation, it's probably "okay" and you can get away from it. There are some environments like this. But I agree that in the general sense, especially with lots of apps banging on the same set of data, it's bad form.

I just try to counter the argument "the database doesn't need to validate because the app can do it" wherever I see it, because it just doesn't happen that way even though it's technically possible.
