Una opción es usar un WITH cláusula para asignar sus parámetros a una tabla ficticia.
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
O si prefiere otra vista en línea:
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
Y luego reemplace todas las variables de vinculación existentes con referencias a la columna equivalente de la tabla de parámetros temporales, es decir, cambie esto:
b.grn_date<=:TO_DT)
a esto:
b.grn_date<=tp.to_dt)
