Hi,
Alias and Synonym both are alternative names to a table
name. But the major difference between Alias and Synonym is
that
>>>Alias can be used to refer a table at different location
( meaning different or remote system and it is not provate
to user who has created it)
>>> Synonym is used to refer table in the same location
with different name. Synonym is very much provate to the
user who has created it.
>>> Regarding dropping ALIAS and SYNONYM I am doubtful.
I have read that if we drop base table or base view then
both alias and synonym are also dropped (As per C.J.DATE
DB2 version 4.0). Please update if anybody has more on this.
