Need Example for Postgres 11 - Procedures

I need help with a simple script. Need advice and a working example of how to run a Procedure with Commit and returning a dummy result back from it. I have a example that you can reference but it is not working perfectly yet. i am not able to retrieve the result from the refcursor after i add the commit. e.g. script CREATE OR REPLACE PROCEDURE oureadata.pg_boweb_cms_category_update_v2(pid character, pcategoryname character varying, pwebcode character varying, porder numeric, pupdatedby character varying, pupdateddate timestamp without time zone, plang character varying, INOUT cresults refcursor) LANGUAGE plpgsql AS $procedure$ DECLARE cnt bigint; rtnCode char(1); BEGIN cresults := 'cur'; BEGIN update oureadata.CMS_CATEGORY set FCATEGORYNAME = pCategoryName, FWEBCODE = pWebCode, FORDER = pOrder, FUPDATEDBY = pUpdatedBy, FUPDATEDDATE = pUpdatedDate, FLANGCODE = pLang where lower(FID) = lower(pId); commit; end; OPEN cresults FOR VALUES ('stringresult'); end; $procedure$ AND to execute the above script.. i use : BEGIN; CALL oureadata.pg_boweb_cms_category_update_v2('e72fa40e-2447-4d59-b6cd-76625d180c32', '1', 'SG988', 3, 'testadmin', '2018-01-11 14:32:50', 'en-gb', ''); fetch all in cur; commit; PM me if you can help.
