<p>Hi ,</p>
<p> </p>
<p>I am new to BIRT so pardon my lack of knowledge . I just cannot figure out how to write MongoDB queries in BIRT . I connected to a MongoDB data source and thats where the problem begins ! </p>
<p> </p>
<p>I have a collection with certain data . Using mapReduce i can get the required fields that i need to use in building my chart.But i do not know how to build the mapReduce query in birt.</p>
<p> </p>
<p>Should i select my collection form the drop down ? Or do i need to select run database commands ? Where do i write my mongodb queries ? Do i write them as it is or would I need modifications ? </p>
<p> </p>
<p>Wherever i write my queries in BIRT I get an error saying : error in parsing JSON expression.</p>
<p> </p>
<p>Please guide ! Waiting for your reply !</p>
