It would be super useful to be able to put programmatic constraints on columns in tables. Such as ensuring a Number column that is meant to represent cost_per_unit_in_usd, is always a positive number.
Even if it’s not full programmatic support, some real simple canned constraints like IS_POSITIVE dropdown would be infinitely better than what currently exists.
And no, I don’t want to litter my code with checks, that’s the whole point of this request, so don’t suggest it please.
