Hello Pepe,

RETURN NEW; is a statement only for functions which are declared with RETURNS TRIGGER and are used by triggers.

Even then no statement after the RETURN NEW; would ever be executed, so it remains unclear what v_Ret := SQLSTATE; i is supposed to do.

Regards,

Holger

Hello Experts,
Would you please help me why I can't call the function to delete table and insert data from another table?   Simple deletion and insert from one to other are fine 
DELETE FROM bnft_hist_actn_ldim;
INSERT INTO bnft_hist_actn_ldim  SELECT stg.bnft_hist_actn_id, stg.bnft_hist_actn_src_cd, stg.bnft_hist_actn_desc, stg.mig_filename FROM stg_bnft_hist_actn_ldim stg;
----- but when I put in the stored function, it's not working.
My stored function script is:

CREATE OR REPLACE FUNCTION pr_mig_stg_bnft_hist_actn_ldim(OUT v_Ret integer) AS $$
DECLARE          v_ErrorCode             varchar(32);         v_ErrorMsg              varchar(512);         v_Module                varchar(32) = 'pr_mig_stg_bnft_hist_actn_ldim';          BEGIN
    DELETE FROM bnft_hist_actn_ldim;
    INSERT INTO bnft_hist_actn_ldim      SELECT stg.bnft_hist_actn_id, stg.bnft_hist_actn_src_cd, stg.bnft_hist_actn_desc,          stg.mig_filename     FROM stg_bnft_hist_actn_ldim stg;
RETURN NEW;
    v_Ret := SQLSTATE;
exception       when others then v_ErrorCode := SQLSTATE;         v_ErrorMsg  := SQLERRM;         v_Ret       := v_ErrorCode;

PERFORM pr_write_error_log ();  
END; $$ LANGUAGE 'plpgsql';

SELECT pr_mig_bnft_hist_actn_ldim();
execute the store funtion no error but two tables are the same and didn't delete and/or insert any from one to other;
thank you for looking into it.
v/r,
