Another thread: What is the use case for having

InsertStatement.get

return

T?

? The only use in the project that ought to use this functionality at all is

fun <Key:Comparable<Key>, T: IdTable<Key>> T.insertIgnoreAndGetId

. It seems to me that it ought to be changed to

T

and instead define a

InsertStatement.tryGet

for the much rarer use so can avoid having !! just to retrieve a generated key.

Nullable columns could produce

null

on insert and that's not the 'null == value was absent from insert'

But since

T

isnt contrained to

Any

it would just be ie.

Int?

which would work. Or I am not understanding you correctly. I have submitted a pull request with the change and a test that shows retrieval of null values.
