如何从sql Date中删除时间

Question

我没有使用日期时间作为我的桌子的价值但我想知道为什么时间仍然出现：

以下是获取gridview输出的代码：

   private void CalendarDataGrid()
    {
        con.Open();

        cmd = new SqlCommand(@"SELECT StocksHistory.DateTrack,Stocks.ItemID
                            ,StocksHistory.StockIn,StocksHistory.StockOut
                            ,StocksHistory.StockOnHand
                            FROM Stocks
                            FULL OUTER JOIN StocksHistory
                            ON Stocks.ItemID = StocksHistory.ItemID
                            WHERE DateTrack between @date1 and @date2", con);




        cmd.Parameters.AddWithValue("@date1",txtDate1.Text);
        cmd.Parameters.AddWithValue("@date2",txtDate2.Text);


        da = new SqlDataAdapter(cmd);
        dt = new DataTable();
        da.Fill(dt);
        GridView1.DataSource = dt;
        GridView1.DataBind();
        con.Close();
    }

我怎样才能获得日期？

Answer 1

我找到了解决方案。 Reference

<asp:BoundField HeaderText="Date" 
                DataField="SampleDate" 
                DataFormatString="{0:MM/dd/yyyy}"  >

Answer 2

"SELECT cast(StocksHistory.DateTrack as date),Stocks.ItemID
                        ,StocksHistory.StockIn,StocksHistory.StockOut
                        ,StocksHistory.StockOnHand
                        FROM Stocks
                        FULL OUTER JOIN StocksHistory
                        ON Stocks.ItemID = StocksHistory.ItemID
                        WHERE DateTrack between @date1 and @date2"

Answer 3

您只需更新内联SQL即可。 通过CAST（StocksHistory.DateTrack AS DATE）AS DateTrack或CONVERT（DATE，StocksHistory.DateTrack）AS DateTrack替换StocksHistory.DateTrack。
