Paul's presentation on One-DB

    Great presentation there, Paul.  Of course you only barely scratched the surface.  Will the slides be made available for downloading?  Also, I don't recall seeing any slides related to features on One-DB missing in IDS, planned or already in place.  What kind of superset would it be without additional features.

    Here's one feature I have not seen in IDS: A scripting language to match Oracle's (hiss! boo! ;-) PL/SQL, with looping and calling constructs.  SPL just doesn't cut it because it must be compiled into the database.  Or does it already exist but I've been away too long?

    Jacob:

    SQL does indeed contain FOR, WHILE, and generic LOOP constructs. It also includes PREPARE, DECLARE cursor, EXECUTE, FETCH, CLOSE, etc. It is even delivered with the Compatibility bladelet that includes file IO functions that you can install. So, yes, not as powerful as Oracle's PL/SQL, but pretty good now.

    As for what will be in OneDB v3.0.0.1, it has not been definitively announced yet and so not set in stone. At this point it is expected to be minor things like the better support for Kubernetes and other Cloud packaging as Brian spoke about, support for the latest .NET protocol and other APIs.

    Art, I've never seen these features discussed with regard to dbaccess.  I am searching the 1400-page SQL Programming Manual for the word "foreach" (and found it) as well as continue and exit loop statements but those all are still within  the context of a stored procedure.

    Can I write an SQL script containing foreach loops, and prepared cursors as an independent script, not only within a stored procedure?  I didn't get that impression from this manual.

    Or am I just looking in the wrong manual?

    No, Jacob, you are correct. Those constructs are only available within a stored procedure.

    The should be on the IIUG site at some point.

    As the moment I am not aware on 14.10.latest and OneDB 2.latest having any functional differences.  The client layers are different though.

    If you don't want to compile into the engine you could use 4gl and the Aubit compiler ?

    Hi,

    So why are they not interchangeable if the base Informix versions match?

    Regards,

    David.

    After all this, I just realized an important (to me, anyway) detail that I had overlooked:

    I am a heavy user of Jonathan Leffler's great contribution, the Perl module DBD::Informix.  When you install this module it compiles a bunch of ESQL/C components.  I don't know if Jonathan monitors this forum but it would be a great boon to adapters of OneDB if he could establish a compatibility of his opus with OneDB.  Or create a port of his module as DBD::OneDB.

    Are the existing binary components of ESQL/C portable to OneDB?  We've already been told that binaries cannot be plunked into running OneDB applications; they would require recompiling.

    It's just an application so should just work, I have not compiled it with OneDB CSDK but with Informix CSDK it will connect to OneDB

    Cheers

    Thank, Paul.  Good to know.

    I suppose that instead of:
    $dbh = DBI->connect("dbi:Informix:$database");

    we would use:
    $dbh = DBI->connect("dbi:OneDB:$database");

    Jacob:

    No, you would continue to use the same connection string:

    $dbh = DBI->connect("dbi:OneDB:$database");

    David:

    Not sure what you are asking. You can truly replace Informix with OneDB and anything that could connect to and use Informix can use OneDB. So, completely interoperable. Even ER will cluster one to the other (though HDR/RSS/SDS will not). Paul's point was that one should not expect to be able to switch back and forth from one to the other willy-nilly. Pick one and stick to it. You can convert from IBM Informix to OneDB no problem and if it doesn't work out for you, after a short time, and if you do not take advantage of any OneDB features not supported by IBM, you could switch back. But that's it.
