getschematable VS fillschema

hi , I noticed a strange behaviour
using the sqlserver provider I can get autoincrement and nullable info
correctly from getschematable EVEN if I do not call
commandbehaviour.keyinfo

however, if i call fillschema WITHOUT missingschemaaction= addwithkey
these info are not present

looking at the sql profiler, both send a simple select * from mytable
without any other command

How it comes ?

thank in advance
