Hello,

 

Oracle 12 supports identity columns with new GENERATED AS IDENTITY clause.

I've tried to get it work with PowerBuilder Datawindows (using ORA driver). I specified the identity columns in the datawindow update properties dialog. But I can't get it to work. PowerBuilder doesn't gets the generated value from oracle.

 

Does Powerbuilder supports identity columns with Oracle?

Hi René;

  Since this is new to Oracle vs being a long time feature of ASE and SS, I suspect that the ORA driver needs to be "tweaked". Normally in ASE or SS when the DWO recognizes an Identity Column (aka Auto Increment) it issues a "ReSelectRow" command behind the scenes to get the new auto assigned value by the DBMS.

  The bad news is that we probably need to open a Support Ticket for this new O12c feature to be supported. The good news is that your App's can use the ReSelectRow() command today (as a workaround) as that command has been a feature in PB for decades.

HTH

Regards ... Chris

Hi Chris,



I have not tried it but I guess ReSelectRow would not work. PB can't create the where clause to find the row because it doesn't know the values of the primary key column.

Correct .. so set the Update properties to Identity = None. Then use the ReSelectRow.approach

Hello Chris,

I checked this in 2019 R3 and there seems no change in the ORA interface. I was wondering if there are plans to finally "tweak" the driver as you put it?

Best regards,
Konstantin

Hi Konstantin .. There were O19C driver "tweaks" in PB2021 & 2022.

Please feel free to test with these releases. The PB2022 Beta is located here: https://www.appeon.com/developers/pb2022-beta.html

If the above newer PB releases do not address your "Identity" column issue, please open a Support Ticket ad attach a test case with details how to recreate the problem. Thanks!

Regards .. Chris

There is always a support ticket I created in 2018: https://www.appeon.com/standardsupport/search/view?id=1780

I tested it again with PB 2022 Beta with no success.

funny - MS sql server finally added sequences to match oracle around version 12.   I've always thought sequences a much better implementation.
