xsd传值或rdlc传值...急啊!

SELECT zh, ah, a, b, c, classname, units, application_t, charge, number, model, st, et, sa, ea, task, instructions, zod_attendant, zhd_attendant, status, id, Expr1, Expr2, official, sn FROM dbo.report where Expr1='37'-------------------------------------------
问题1:reportviewer+rdlc+aspx之间如何传值,能否把条件语句后在的37改为变量(取aspx页面传过来的值做为变量)...;
    2:如果不能,有没有其它解决办法...
      也就是点击aspx页面上的一条记录,reportviewer+rdlc控件就可以调出该条记录,且只有该条记录(打印或导出PDF-EXECL)..
    谢谢!
附:xsd文件--------------------------------<?xml version="1.0" encoding="utf-8"?>        </Connections>
