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,
