I am currently converting one of our applications to Ada9x using GNAT.
Has anyone tried interfacing GNAT with any databases (eg. Oracle)
Thanks,
Jeff

I don't know anything specific about GNAT and ORACLE working together, but
an important thing to remember is that the GNAT calling sequence is exactly
the C calling sequence, and the GNAT datatypes correspond to the C
datatypes (e.g. int = integer, char = character). Access types and
address values in GNAT look like C pointers EXCEPT for access types for
unconstrained arrays, which are quite different, so avoid their use in
low level interface code.

I have spent the last two weeks attempting to discuss Ada-9x and GNAT with
the good (?) people at Oracle. Out of three technical reps, four
salespeople, and two semi-managers, I found ONE who knew what Ada was.
That individual stated that Oracle was committed to compliance with the
latest standards. He promptly faxed me three pages from the Pro*Ada
reference manuals identifying the various levels/standards of SQL that
Oracle supported.
Even this former Marine knows when to quit hitting his head against the
wall.
Does anyone else know of a DBMS that will operate with GNAT? Preferably
with an existing Ada interface?
And SQL support, as long as I am dreaming?
Vendors feel free to reply. Summary will be posted if I recieve more than
two responses.

Any database which has a C interface should run with GNAT using the PRAGMA
IMPORT. I know you could do this with SYBASE, but it would take some
work.
