Question

My query has too many subqueries and each query has repeated parameters. How to design the report in eclipse. This is my query

    SELECT

order by c.unit_code

The parameters are (:FR_DT,:TO_DT, : p_COMP_CODE, :FR_CAT, :TO_CAT, : p_SUP_CODE) which need to be replaced with ‘?’ while writing the query in dataset. But i don’t know how to replace same parameter which is occurring at multiple places with the query parameters. and How to handle DECODE and between parametes.

Answer 1

One option is to use a WITH clause to assign your parameters to a dummy table.

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

Or if you’d prefer yet another inline view:

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

And then replace all the existing bind variables with references to the equivalent column from the temporary parms table, i.e. change this:

                                b.grn_date<=:TO_DT)

to this:

                                b.grn_date<=tp.to_dt)
