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.

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 fineDELETE FROM bnft_hist_actn_ldim;INSERT INTO bnft_hist_actn_ldimSELECT stg.bnft_hist_actn_id, stg.bnft_hist_actn_src_cd, stg.bnft_hist_actn_desc, stg.mig_filenameFROM 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 $$DECLAREv_ErrorCode varchar(32);v_ErrorMsg varchar(512);v_Module varchar(32) = 'pr_mig_stg_bnft_hist_actn_ldim';BEGINDELETE FROM bnft_hist_actn_ldim;INSERT INTO bnft_hist_actn_ldimSELECT stg.bnft_hist_actn_id, stg.bnft_hist_actn_src_cd, stg.bnft_hist_actn_desc, stg.mig_filenameFROM stg_bnft_hist_actn_ldim stg;RETURN NEW;v_Ret := SQLSTATE;exceptionwhen others thenv_ErrorCode := SQLSTATE;v_ErrorMsg := SQLERRM;v_Ret := v_ErrorCode;PERFORM pr_write_error_log ();END;$$ 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,Bach-Nga

Then I would add a couple of RAISE statements because it sounds me strange that the function is invoked without producing any error nor results. Last, I would change the DELETE with a TRUNCATE, assuming you are not inserting the very same quantity of rows on the next step. Luca
