Strong Liu commented on HHH-6779:
---------------------------------

okay, smallint takes 2 byte but numeric(3,0) takes 5 bytes, so i think smallint win

>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.6.8, 4.0.0.CR5

> ByteType maps tinyint and byte
> which byte on java is [-128,127]
> but on sybase / sql server, the tinyint scope is [0-128)
> this causes org.hibernate.test.typedescriptor.ByteTest fail, stace trace is same as HHH-3679
> change the mapping of tinyint to number(3,0) in org.hibernate.dialect.AbstractTransactSQLDialect would fix this issue
