How I can populate data in birt report by passing parameters in the URL

问题

I want to pass the parameters in the URL of the BIRT Report. In my reports there are 3 parameters like StoreId, fromdate and todate. I have also tried to write the code of beforeOpen Script of my dataSet in the Birt. Its is as :

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";  

And i wrote my URL as :

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

At the end of the report I am getting such error :

The following items have errors:

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";



":

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";

A BIRT exception occurred. See next exception for more information.
Report parameter "Store_id" does not exist..

If anyone knows then help me.

Make sure the Report Parameter Name matches the one given in the URL. You are looking for the Report Parameter named "Store_id" in this script but in the first paragraph of your question you state the name as "StoreId". I think you need to change the Report Parameter name from "StoreId" -> "Store_id".
