eclipse中帶有子報表過濾器的Birt報表設計

Question

我的查詢有太多的子查詢，每個查詢都有重複的參數。如何在eclipse中設計報表。這是我的查詢

order by c.unit_code 

的參數是（：FR_DT，：TO_DT，：p_COMP_CODE，：FR_CAT，：TO_CAT，：p_SUP_CODE） '？'這就需要被替換同時在數據集中寫入查詢。但我不知道如何用查詢參數替換多個地方發生的相同參數。而如何處理DECODE和指標的影響之間。

一種選擇是使用WITH條款爲您的參數分配給虛擬表。

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 

或者，如果你更喜歡另一種內嵌視圖：

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 

然後從臨時PARMS表等效列引用替換現有的所有綁定變量，即改變這一點：

       b.grn_date<=:TO_DT) 

這樣：

       b.grn_date<=tp.to_dt)
