asp.net - Production environment not fetching sql data set -


my asp.net code not fetching data set sql database in production environment. code return no records, same code working fine in development environment. have feed crystal report fetched data set.

here code:

private sub generatereport1(sql1 string)     dim crreportdocument = new crystaldecisions.crystalreports.engine.reportdocument()     try         dim reportname string = "kpiestoverallreport.rpt"          dim ds new dataset()         ds = getdataset(sql1)          'ds = dataaccesshelper.dataaccess.executedataset(dataaccesshelper.dataaccess.connectionstring, "usp_bms_kpi_estimation_performance_report ", commandtype.storedprocedure, param)          session("dscrstalreport") = ds         crreportdocument.filename = server.mappath("~//kpiestoverallreport.rpt")          crreportdocument.setdatasource(ds)          session("reportdoc") = crreportdocument          if ds isnot nothing andalso ds.tables(0).rows.count > 0             scriptmanager.registerstartupscript(me, gettype(string), "showreport", "window.open('crystalreportviewer.aspx?','_blank','');", true)         else             lblmsg.text = "no records found..!"             'scriptmanager.registerstartupscript(me, gettype(string), "no records found.", "alert('no records found.');", true)         end if      catch ex exception         lblmsg.text = ex.message     end try  end sub

you code not provide enough information on issue.

if simplify code get

dim ds new dataset() ds = getdataset(sql1) if (ds isnot nothing andalso ds.tables(0).rows.count > 0) false     lblmsg.text = "no records found..!" end if

where "no records found..!" because either ds nothing or tables(0) has no recods.

this happen when sql1 returns no records or have error in getdataset method return nothing.

to troubleshoot, need debug getdataset() , see does.
