Help regarding sorting report

I have created als.rdlc file for my report it has data from the tableLS ( eg. Month , year, target, actual, etc ), and i have export thatLS.rdlc file in myreport.aspx by using ReportViewer from the toolbox. So when i complie that report.aspx it pull up the report. It pulls up all the data from LS but what i want is sort them by YEAR then MONTH, I Dont know how to do it.? Can any one help me???

Try adding an ORDER BY to the SELECT. If that does not work, change to using a stored procedure.|||I dont know how would you sort it? when i run the report it pulls up the whole database table , so how would i put a search in that?? I am not familer with sorting much.|||

Just change
SELECT A, B, C FROM TABLE

to
SELECT A, B, C FROM TABLE ORDER BY ID
