Question

I’m trying to run the following query. It was working fine until i added the column gpv.i_val

the error i’m receiving is “object gpv does not exist” when clearly it does. I’m assuming this is something simple but can’t seem to place my finger on it.

             SELECT 
             gpv.i_val,
             gcv.i_pln,
             gcv.c_typ_cov,
             gcv.d_eff,
             gcv.d_eff_pln,
             gcv.c_sta,
            gcv.d_sta,
            gcv.c_mde_bft_fst,
            gcv.a_bft_fst,
            gcv.c_mde_bft_sec,
             gcv.a_bft_sec,
            gcv.c_mde_bft_trd,
             gcv.a_bft_trd,
             gcv.p_cre_hom,
             gcv.c_cl_rsk,
             gpv.c_val,
             gcv.c_pol


            FROM Pearl_P.tltc906_gcv gcv,
             pearl_p.tltc912_gpv gpv

              WHERE  gcv.i_pln > 0
            AND gcv.i_pln = gpv.i_pln
            and gcv.c_pol between 'lac100001' and 'lac100004'

         UNION

             SELECT
            gpv.i_val,
             gcv.i_pln,
             gcv.c_typ_cov,
             gcv.d_eff,
             gcv.d_eff_pln,
             gcv.c_sta,
             gcv.d_sta,
             gcv.c_mde_bft_fst,
             gcv.a_bft_fst,
             gcv.c_mde_bft_sec,
             gcv.a_bft_sec,
             gcv.c_mde_bft_trd,
             gcv.a_bft_trd,
             gcv.p_cre_hom,
             gcv.c_cl_rsk,
             gcv.c_pol,
             ''
        FROM Pearl_P.tltc906_gcv gcv

            where NOT EXISTS(
            SELECT 1
            FROM pearl_p.tltc906_gcv gcv,
             pearl_p.tltc912_gpv gpv

            WHERE  gcv.i_pln > 0
            AND gcv.i_pln = gpv.i_pln
            )

Your second select in the UNION references GPV, but the table itself is not included?

 SELECT gpv.i_val,
        ....
        ....
             ''
        FROM Pearl_P.tltc906_gcv gcv
        WHERE ....
