what's wrong with my procedure?

kclark

Hi codename, have you linked the query to the parameter in the parameters tab in edit data set?

codename_

Hi Kclark...

I only did set the parameter as "id, integer, default value = 0"
do i need to configure property binding? I dont want to enter any id in the dialog box that's why I choose to have the paremeter in my url.

Do i need to link it to report parameter?But I dont want to prompt for parameter...

kclark

You'd still need to link the parameter. As long as you keep "Is Required" unchecked you won't be prompted for a parameter and you can pass it in the URL. I've attached an example, I passed the state to the report using this:<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>http://localhost:8080/birt/frameset?__report=paramsexample.rptdesign&NewParameter=CA</pre>

@kclark

Ive got some error

Table (id = 7):
+ An exception occurred during processing. Please see the following message for details:
Failed to prepare the query execution for the data set: Data Set
Cannot set a null value to parameter 1.
org.eclipse.birt.report.data.oda.jdbc.JDBCException: Cannot set preparedStatement null value.
SQL error #1:Parameter metadata not available for the given statement

kclark

Can you post your rptdesign please?

codename_

what I did was I make a query first
select *
from news_item
where id = ?

then I set the parameter to the parameters tab
Name=id
DataType=int
Direction=input
Linked to Report Parameter=(ParamName with "isRequired Unchecked")

Then my URL "http://localhost:8080/WebViewerExample/preview?__report=new_report_1.rptdesign&id=1"

Why still have errors?

Here is my design<br />

OH! I figured out the problem. I set id to my url instead of using the paramName
