A some languages has a generic PRAGMA keyword. So I would be much more

PRAGMA Assert(found);

It is much more close to ADA, and it allows a reuse of new keyword for any
other usage in future (your proposal is too simply, without possibility
open new doors in future). And we can define a some standard predefined
asserts too - like Assert, AssertNotNull, AssertNotEmpty, ...

I don't see why e.g. PRAGMA AssertNotEmpty(foo); would be better than ASSERT NotEmpty(foo); and the NotNull version is even sillier considering the expression is arbitrary SQL, and we'd have to do all kinds of different versions or people would be disappointed (AssertNull, AssertNotNull, AssertExists, AssertNotExists, etc.).

I see what you're trying to do, but I don't think crippling new features just because we might do something similar at some point is a good idea. I'm guessing this is what happened with the row_count syntax, which made the feature an absolute nightmare to use.

other issue - A asserts macros has one or two parameters usually. You
should to support two params assert (with message).

That I think is worth looking into.
