Using serializable in hibernate what underlying database types do i use

I need to use a serializable type in hibernate (to store a Subject (security)) All this works fine.

I just need to know what the underlying database types are for the following databases:

• MSSQL - I used 'image'
• db2 -
• postgre -
• mysql -

Thanks.开发者_运维知识库.

I'd say:

• MSSQL - I used 'image'
• db2 - BLOB(2G)
• postgre - bytea
• mysql - One of the BLOB types
