如何通过在URL中传递参数来填充birt报告中的数据

Question

我想传递BIRT报告网址中的参数。在我的报告中有3个参数，如StoreId，fromdate和todate。我还尝试在Birt中编写我的dataSet的beforeOpen Script代码。它是：

var store_id;
var from_date;
var to_date;

store_id = params["Store_id"].value;
from_date = params["fromdate"].value;
to_date = params["todate"].value;

this.queryText = this.queryText+" where STORE_ID = "+store_id+" AND TRANSFER_DATE BETWEEN "+from_date+" AND "+to_date+ "ORDER BY TRANSFER_DATE ASC";  

我把我的网址写成：

http://localhost:8080/birt/run?__report=adminMasterTransferReport_new.rptdesign&Store_id=1&fromdate=2014-04-26&todate=2014-06-06

在报告的最后，我收到了这样的错误：

以下项目有错误：

ReportDesign (id = 1):
+ There are errors evaluating script "var store_id;
var from_date;
var to_date;

store_id = params["Store_id"].value;
from_date = params["fromdate"].value;
to_date = params["todate"].value;

this.queryText = this.queryText+" where STORE_ID = "+store_id+" AND TRANSFER_DATE BETWEEN "+from_date+" AND "+to_date+ "ORDER BY TRANSFER_DATE ASC";



":

" + var store_id;
var from_date;
var to_date;

store_id = params["Store_id"].value;
from_date = params["fromdate"].value;
to_date = params["todate"].value;

this.queryText = this.queryText+" where STORE_ID = "+store_id+" AND TRANSFER_DATE BETWEEN "+from_date+" AND "+to_date+ "ORDER BY TRANSFER_DATE ASC";



 + "

如果有人知道那就帮助我。

确保报告参数名称与URL中指定的名称相匹配。您正在寻找名为＆＃34; Store_id＆＃34;的报告参数;在此脚本中，但在问题的第一段中，您将名称命名为＆＃34; StoreId＆＃34;。我认为您需要更改＆＃34; StoreId＆＃34;的报告参数名称。 - ＆GT; ＆＃34; STORE_ID＆＃34;
