What is difference between the Advantage Database Server free table and Advantage Database Server normal table.
Thanks !
回答1:
Free table - The table is independent of a data dictionary, it's just a set of files in the fs (table.adt, table.adi, table.adm).
Dictionary table - The table con only be used after logging into the specific data dictionary that owns the table.
The technical difference is that some bytes in the adt file header are different, so that you can't open a dictionary table with a free connection.
