Visual Studio 2012 dataset not working after addind Datatable in Dataset.xsd

Hi All,

I encounter a very very weird error which i do not face in Visual Studio 2010.

All the SQL result return in dataset format has 0 row even if it should return record after adding table to DataSet.xsd.

Below is my code which should return me a row but after adding a datable to Dataset.xsd it returns me 0 records.

protectedvoidPage_Load(object sender,EventArgs e){DataSet dsUser =newDataSet();Int32  icount;

        dsUser =SearchUser("ELIM","","","","ALL","ALL");
        icount = dsUser.Tables[0].Rows.Count;}privateDataSetSearchUser(String vstrNTAcc,String vstrEmpNo,String vstrName,String vstrRole,String vstrStatus,String vstrCertApprv){DataSet dsUser =newDataSet();String oradb ="";

        oradb =ConfigurationManager.AppSettings["BARWEBConnString"].ToString();OracleConnection oconn =newOracleConnection(oradb);try{
            vstrNTAcc = vstrNTAcc.ToUpper();
            vstrEmpNo = vstrEmpNo.ToUpper();
            vstrName = vstrName.ToUpper();
            vstrRole = vstrRole.ToUpper();
            vstrStatus = vstrStatus.ToUpper();if(vstrNTAcc ==""){
                vstrNTAcc ="%";}if(vstrEmpNo ==""){
                vstrEmpNo ="%";}if(vstrName ==""){
                vstrName ="%";}if(vstrRole =="ALL"){
                vstrRole ="%";}else{
                vstrRole ="%"+ vstrRole +'%';}if(vstrStatus =="ALL"){
                vstrStatus ="%";}if(vstrCertApprv =="ALL"){
                vstrCertApprv ="%";}OracleCommand ocmd =newOracleCommand();
            oconn.Open();
            ocmd.Connection= oconn;
            ocmd.CommandType=CommandType.StoredProcedure;
            ocmd.CommandText="BAR_WEB.S_COC_GET_USER";OracleParameterOPNTAcc=newOracleParameter();OPNTAcc.Direction=ParameterDirection.Input;OPNTAcc.Value= vstrNTAcc;
            ocmd.Parameters.Add(OPNTAcc);OracleParameterOPEmpNo=newOracleParameter();OPEmpNo.Direction=ParameterDirection.Input;OPEmpNo.Value= vstrEmpNo;
            ocmd.Parameters.Add(OPEmpNo);OracleParameterOPName=newOracleParameter();OPName.Direction=ParameterDirection.Input;OPName.Value= vstrName;
            ocmd.Parameters.Add(OPName);OracleParameterOPRole=newOracleParameter();OPRole.Direction=ParameterDirection.Input;OPRole.Value= vstrRole;
            ocmd.Parameters.Add(OPRole);OracleParameterOPCertApprv=newOracleParameter();OPCertApprv.Direction=ParameterDirection.Input;OPCertApprv.Value= vstrCertApprv;
            ocmd.Parameters.Add(OPCertApprv);OracleParameterOPStatus=newOracleParameter();OPStatus.Direction=ParameterDirection.Input;OPStatus.Value= vstrStatus;
            ocmd.Parameters.Add(OPStatus);OracleParameterOPRefCursor=newOracleParameter("OPRefCursor",OracleDbType.RefCursor);OPRefCursor.Direction=ParameterDirection.Output;
            ocmd.Parameters.Add(OPRefCursor);OracleDataAdapter da =newOracleDataAdapter(ocmd);
            da.Fill(dsUser);return dsUser;}catch(Exception ex){throw ex;}finally{
            oconn.Close();}}

Below is how i add the databale to the DAtaSet.xsd.This datatable is a very plain that i add only column to it without having any connection.

Is there any special configuration required for VS2012? I need the datatable inside Dataset.xsd because i want to use it in reportviewer.

Help Please!!
