Postgres 11 - COMMIT Procedure


Postgres 11 - COMMIT Procedure



With the recent update of Postres 11. It now supports stored procedures. Transactions are finally supported in stored procedures in Postgres. However, I have been trying to perform a commit within a procedure with no luck.


CREATE OR REPLACE PROCEDURE test_update(
IN pid character,
IN pcategoryname character varying,
IN pwebcode character varying,
IN porder numeric,
IN pupdatedby character varying,
IN pupdateddate timestamp without time zone,
IN plang character varying,
INOUT cresults refcursor)
LANGUAGE plpgsql
AS
$BODY$
DECLARE

cnt bigint;
rtnCode char(1);

BEGIN
cresults := 'cur';

BEGIN
update test_table
set FCATEGORYNAME = pCategoryName,
FWEBCODE = pWebCode,
FORDER = pOrder,
FUPDATEDBY = pUpdatedBy,
FUPDATEDDATE = pUpdatedDate,
FLANGCODE = pLang
where lower(FID) = lower(pId);
COMMIT;
end;
.
.
EXCEPTION WHEN ....
.
.
OPEN cresults FOR VALUES ('stringresult');

end;
$BODY$;



UPDATED
Edited so that the Update and Commit is within a block that does not have any exception.



This was previously used to execute the procedure. I was able to fetch the result of the refcursor. Does not work anymore after the commit is added.:


begin;
CALL testupdate('ad3caecb-9235-4945-b37a-9b7ff89fdfe0','aa','138',0,'test','2018/06/29 18:04:03','zh-cn','');
fetch all in cur;
commit;



but when i execute with:


CALL testupdate('ad3caecb-9235-4945-b37a-9b7ff89fdfe0','aa','138',0,'test','2018/06/29 18:04:03','zh-cn','');



.. it runs fine and the row got updated, but this way of running doesnt allow me to fetch the result my refcursor.



Is there any way to get the result of my refcursor when excuting a procedure with COMMIT. Any help is greatly appreciated. Thanks





And which exception in throws exactly?

Exception: SQL Error: invalid transaction termination at line 19 COMMIT

Quote from the manual: "A transaction cannot be ended inside a block with exception handlers." - you need to put the update and commit into a block without an exception handler (currently your procedure is a single block that has an exception handler)

update


commit





Okay removing the exeption does work if i run "Call <proc>" alone, Thanks!, But when i run "begin; Call <proc>; fetch all in cur; commit;" the same exception error appears. I have to call it the latter way to get the result of the cur. is this possible?

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
