eclipse中带有子报表过滤器的Birt报表设计

Question

我的查询有太多的子查询，每个查询都有重复的参数。如何在eclipse中设计报表。这是我的查询

order by c.unit_code 

的参数是（：FR_DT，：TO_DT，：p_COMP_CODE，：FR_CAT，：TO_CAT，：p_SUP_CODE） '？'这就需要被替换同时在数据集中写入查询。但我不知道如何用查询参数替换多个地方发生的相同参数。而如何处理DECODE和指标的影响之间。

一种选择是使用WITH条款为您的参数分配给虚拟表。

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，如果你更喜欢另一种内嵌视图：

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 

然后从临时PARMS表等效列引用替换现有的所有绑定变量，即改变这一点：

       b.grn_date<=:TO_DT) 

这样：

       b.grn_date<=tp.to_dt)
