Fetching data using last Datetime

Question

I have to show these details in a gridview as Tempname as unique and associated datetime in drodown and the last run by name in a label. Unable to upload the Table picture as i dont have enough reputation.

    private void GridLoading()
    {
        DataSet ds = new DataSet();
        ds = Common.LoadingGrid();
        GridView1.DataSource = ds;
        GridView1.DataBind();
    }

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataSet ds = new DataSet();
            Label lblName = e.Row.FindControl("Label1") as Label;
            ds = Common.RunByDate(lblName.Text);
            DropDownList ddl = e.Row.FindControl("DropDownList1") as DropDownList;

            ddl.DataTextField = "RunDate";
            ddl.DataValueField = "RunDate";
            ddl.DataSource = ds;
            ddl.DataBind();
            var items = ddl.Items;
          }           
    }

But i am unable to get the Runby name in the label.How can i display it?Below are my stored procedures

    Select distinct TempName from SV_JobHistoryTable 

    SELECT TempName,RunDate
    FROM SV_JobHistoryTable  where TempName=@tempname 

Answer 1

So far what i have understood is, you want to get the Unique TempName with the Lastest RunDate, all you need is this query:

SELECT RunByName, MAX(RunDate)
FROM SV_JobHistoryTable  
WHERE TempName = @tempname 
GROUP BY RunByName

Answer 2

try this:

SELECT TempName,RunDate,max(Runbyname)
    FROM SV_JobHistoryTable  where TempName=@tempname 
    group by TempName,RunDate

Answer 3

Is this what you want?

    SELECT TOP 1
         RunByName, RunDate
    FROM 
        SV_JobHistoryTable 
    WHERE 
        TempName = @tempname                    
    ORDER BY 
        RunDate DESC    

Or do you want to record more entries than one?
