如何将“词法参数”（用于 Oracle 报告）之类的参数用于 Pentaho 报告。
以下是我的 oracle 报告查询和“AFTERFORM”触发代码
SELECT FEI.CUSTOMER_NAME
,CASE
WHEN FEI.OWNBRANCH_CUSTOMER = 0 THEN FEI.LC_NO || ' CTPU'
ELSE FEI.LC_NO
END LC_NUMBER
,A.OUTSTANDING
,CR_APPR_REF_NO
,MARGIN_REALIZED_AMT_CCY
,DECODE (SIGN ( MARGIN_BUILD_AMT - MARGIN_SET_AMT)
,'-1', 0
, (MARGIN_BUILD_AMT - MARGIN_SET_AMT))
SHORTFALL
FROM IMPORT_LC FEI
,CURRENCY FEC
, (SELECT LOGIN_BRANCH, REFERNCE_NO, ABS ( SUM ( AMOUNT_DR) - SUM ( AMOUNT_CR)) OUTSTANDING
FROM TRANSACTIONS
WHERE GLOBAL_TRANS_NO IS NOT NULL
AND PRODUCT_CODE = :P_PRODUCT_CODE
AND LOGIN_BRANCH = NVL ( :P_REPORT_BRANCH, LOGIN_BRANCH)
AND TRANS_DATE <= :P_TRANS_DATE
AND GLCODE = :P_LIAB_ACC
HAVING ABS ( SUM ( AMOUNT_DR) - SUM ( AMOUNT_CR)) > 0
GROUP BY LOGIN_BRANCH, REFERNCE_NO) A
WHERE A.LOGIN_BRANCH = FEI.OWN_BRANCH
AND A.REFERNCE_NO = FEI.LC_NO
AND FEI.IMP_AMEND_NO =
(SELECT MAX ( FF.IMP_AMEND_NO)
FROM IMPORT_LC FF
WHERE FF.LC_NO = FEI.LC_NO AND FF.OWN_BRANCH = FEI.OWN_BRANCH)
AND FEI.OWN_BRANCH_CODE = NVL ( :P_REPORT_BRANCH, FEI.OWN_BRANCH)
AND FEI.CUSTOMER_CODE = NVL ( :P_CUST_CODE, FEI.CUSTOMER_CODE)
AND FEI.IMP_CURR_CODE = FEC.CUR_CODE
AND FEI.PRODUCT_CODE = :P_PRODUCT_CODE
&P_W
Where after parameter form trigger我将 where 子句的值设置为：
BEGIN
IF :P_TRANS_DATE < GET_CURRENT_DATE THEN
:P_W :='';
ELSE
:P_W :=' AND FEI.LC_STATUS <>6 and FEI.OPERATION_CODE<>'20' ';
END IF;
:P_W:=:P_W||CASE WHEN :P_OTHER_BRANCH=1
THEN ' AND FEI.OWN_BRANCH=FEI.CUSTOMER_BRANCH '
ELSE' AND FEI.OWN_BRANCH<>FEI.CUSTOMER_BRANCH '
END;
END;
我想在Pantaho中部署此查询，但作为 Pantaho 的初学者，我如何在其中实现词法参数部分...
