Обсуждение: how to call a stored function on conflict

Hi Pepe,

the SQLSTATE is not an integer or bigint, so it cannot be stored in a variable declared as bigint.

See https://www.postgresql.org/docs/current/errcodes-appendix.html

Hello experts,

I have a store function on conflict to update and insert features information from one table to another table  

My code is:

create or replace FUNCTION ecisdrdm.pr_mig_stg_application_cdim (v_Ret OUT bigint ) 

as $$

declare 

        v_ErrorCode             bigint;

        v_ErrorMsg              varchar(512);

        v_Module                varchar(32) = 'pr_mig_stg_application_cdim';

begin

----

-- MERGING: STG_APPLICATION_CDIM into APPLICATION_CDIM

----

INSERT INTO application_cdim AS prod (prod.application_id, prod.receipt_number,prod.init_frm_id, prod.frm_typ_id,  

prod.sbmtd_dt_id, prod.crtd_user_id, prod.init_src_sys_id, prod.init_svc_ctr_id, prod.mig_filename) 

SELECT stg.application_id, stg.receipt_number, stg.init_frm_id, stg.frm_typ_id, stg.sbmtd_dt_id, stg.crtd_user_id,

stg.init_src_sys_id, stg.init_svc_ctr_id, stg.mig_filename 

FROM ecisdrdm.stg_application stg

ON CONFLICT (application_id)  DO UPDATE 

SET ( prod.init_frm_id, prod.frm_typ_id,prod. sbmtd_dt_id, prod.crtd_user_id, 

prod.init_src_sys_id, prod.init_svc_ctr_id, prod.mig_filename, prod.mig_modified_dt

)

= 

(SELECT stg.init_frm_id, stg.frm_typ_id, stg.sbmtd_dt_id, stg.crtd_user_id,

  stg.init_src_sys_id, stg.init_svc_ctr_id, stg.mig_filename, current_timestamp

FROM ecisdrdm.stg_application_cdim stg

WHERE prod.receipt_number = stg.receipt_number

);           

RETURN;

   ----

   -- Set the return code to 0

   ----

   v_Ret := SQLSTATE;

----

-- Exception error handler

----

exception

   when others then

v_ErrorCode := SQLSTATE;

v_ErrorMsg  := SQLERRM;

v_Ret       := v_ErrorCode;

----

-- Commit the record into the ErrorLog

----

PERFORM pr_write_error_log( v_os_user, v_host, v_module, v_ErrorCode, v_ErrorMsg );

----

-- Intentionally leaving the "commit" to application

----

end;

$$ language plpgsql;

and my other function for pr_write_error_log is 

CREATE OR REPLACE FUNCTION ecisdrdm.pr_write_error_log (

v_os_user character varying,

v_host character varying,

v_module character varying,

v_errorcode integer,

v_errormsg character varying)

    RETURNS void

    LANGUAGE 'plpgsql'

    COST 100

    VOLATILE 

AS $BODY$

BEGIN

START TRANSACTION;

INSERT INTO ecisdrdm.errorlog(tstamp, os_user, host, module, errorcode, errormsg)

VALUES

   (CURRENT_TIMESTAMP, CURRENT_USER, inet_server_addr(), v_module, v_ErrorCode, v_ErrorMsg );

        /* commit; */

end;

$BODY$;

ALTER FUNCTION ecisdrdm.pr_write_error_log (character varying, character varying, character varying, integer, character varying)

    OWNER TO "PSmasteruser";

they all created successfully.

when I execute the function of pr_mig_stg_application_cdim as "select ecisdrdm.pr_mig_stg_application_cdim(); "

ERROR: invalid input syntax for integer: "42P01" CONTEXT: PL/pgSQL function ecisdrdm.pr_mig_stg_application_cdim() line 41 at assignment SQL state: 22P02

may I know how to execute the stored function?  What did wrong on my queries?

thank you for your help.

May I suggest to log the running queries and see what is effectively
executing your function?
