Yes, I am using Native stuffs :)

No, I am afraid this is not what I wanted...

See, in System.gdb I have tables, i.e. Currency, Unit, Dept, etc...

In other databases, I need the same info from those shared tables.

In Access, we are able to create a 'shadow' table from external source using Link
Table, which can be table from other Access database, or even other Excel
database, and it will be updated automatically whenever somebody updates the
external source.

Now, I am just wondering whether is it possible to do the same thing with IB/FB and
IBO ?? If not possible, then I think I have to create tables in those databases with
the same structure, and insert/update/delete the changes made in the System.gdb

It will arise another problem for me, how to detect the SQL statement generated by
IBO when we are inserting/updating/deleting, so I can simply assign the SQL while
changing the IB_Connection only...

Thanks,
