i still can't figure out where ConvertInt comes into play here with Sql..

i understand that operator[]() returns a Value, which content is determined at runtime. is it using a ConvertInt?
(have to admit i haven't used Sql in Upp yet).

No. The example was to demontrate that you should never (or almost never) depend on particular number type in Value.

Use IsNumber, then assign.

Quote:

anyway, the question is, what purpose does the ConvertInt serve to.. to convert stuff to a Value with an int inside.

It already has 'int' inside... (stored in lower 32-bits of int64 Smile

. Frankly, it is not quite unlikely that at some point in future, we completely abandon INT_V and will only store int64 in Value.
