How to send query thru Map from java application.I did the the following-

Code:

HashMap <String,String> map=new HashMap<String,String>()
map.put("Sql","Select * from loan where loan_id=1"«»);
JasperPrint jasperPrint = JasperFillManager.fillReport(reportFile, map, jdbcConnection);
JasperViewer.viewReport(jasperPrint);

And I also set $P!{Sql} in report query and made a parameter name- Sql, type- String. Will it work

No it wont. You need to manualy create the fields in the report. The fields will not be generated automatically by Jasper when you run the report. So what will happen is your SQL will probaly run then you will get an error because the report wont know what to do with your columns.

 

What I've done is manually created the fields and passed a query with a defined number of fields.

 

ie "Select col1, col2, col3 from table where some condition"

Brother first thing is dat whether u agree that my code is right or not.If my coding is ok, then can I just make a query -"Select * from tablename" in iReport and let my code/application choose which condition to use.I mean-can I use-"Select * from tablename" in ireport query and compile it, and use "Select * from where condition" in my application code.Will it work.Bcos this way the report is getting all the coloumns but depending upon the condition in application, it will fill it accordingly.
