So what you really need to tell us is what you need the exported data
for. There are tools around that can convert tables and other DB objects
from one DB engine's native format to another's. Whether the converted
data's structure is directly useful or not depends entirely on the degree
to which each engine's native database architecture is compatible with the
other's. So, for example, Firebird and InterBase data is virtually
interchangeable; Oracle and Firebird data structures are highly
compatible; while the typical ISAM-style structures (e.g. Paradox, MySQL,
Access) need quite a lot of work to make them in productive databases for
use with Oracle or InterBase.
that converting engines can understand, for example, double quotes around
strings that were/should be stored as strings, commas to mark the ends of
all fields other than the last in a record, line-feeds plus or minus
carriage returns to mark the end of a record, and a marker to indicate end
of file. A text file has no ability to store typed data, merely bytes, so
dates have to be encoded for conversion to whatever format is used by the
destination database engine; and the strings that represent number types
are generally recognised by having no field markers.

according to these conventions.

a useful security hole with benefits for anyone who is denied access to the

it up.

>I'm hoping to get it in some sort of semi-generic SQL formatThere is no such thing as "generic SQL format". SQL is a language
interface. If a particular database engine's implementation of the SQL

implementation might be considered "generic".

>The data is stored in a .ib file.The suffix on a Firebird or InterBase database file has no significance -
it can be anything, or nothing at all. It can provide a clue that it was
created by an InterBase server, since the ".ib" convention was recommended
to developers once the previous convention (".gdb") was hijacked by
Microsoft and caused problems on Windows ME and XP. If your source
