Birt rapport design i formørkelse med subrapport filter

En mulighed er at bruge en WITH klausul for at tildele dine parametre til en dummy-tabel.

WITH tmp_parms AS (
    SELECT ? as fr_dt, ? as to_dt, ? as p_comp_code,
        ? as fr_cat, ? as to_cat, ? as p_sub_code
    FROM dual
)
SELECT C.COMP_CODE,C.MATCODE, ... etc
FROM tmp_parms tp,
        (
        SELECT A.COMP_CODE,A.MATCODE, ... etc

Eller hvis du foretrækker endnu en integreret visning:

SELECT C.COMP_CODE,C.MATCODE, ... etc
FROM (
    SELECT ? as fr_dt, ? as to_dt, ? as p_comp_code,
        ? as fr_cat, ? as to_cat, ? as p_sub_code
    FROM dual
) tp,
        (
        SELECT A.COMP_CODE,A.MATCODE, ... etc

Og erstat derefter alle eksisterende bindevariabler med referencer til den tilsvarende kolonne fra den midlertidige parms-tabel, dvs. skift dette:

                                b.grn_date<=:TO_DT)

til dette:

                                b.grn_date<=tp.to_dt)
