Re: can't call function to delete the table

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 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,
