Question

下面的存储过程需要在我编写查询的代码中添加。

if (ddlFormat.SelectedIndex != 0)
{
    String strConnString = ConfigurationManager.ConnectionStrings["CallcenterConnectionString"].ConnectionString;
    SqlConnection con1 = new SqlConnection(strConnString);

    con1.Open();
    SqlCommand cmd = new SqlCommand();
    SqlDataAdapter sda = new SqlDataAdapter();
    DataSet dsDisp = new DataSet();
    cmd.CommandType = CommandType.Text;
    cmd.CommandText = "Select DISTINCT Disposition from CallCenter..Loy_DispMstr where CallType=@CallType and SUBFormat=@Format";
    cmd.Parameters.AddWithValue("@CallType", ddlCalltype.SelectedValue);
    cmd.Parameters.AddWithValue("@Format", ddlFormat.SelectedItem.Text);
    cmd.Connection = con1;
    cmd.ExecuteNonQuery();

    sda.SelectCommand = cmd;
    sda.Fill(dsDisp);

    ddlDisp.DataTextField = "Disposition";
    ddlDisp.DataValueField = "Disposition";

    ddlDisp.DataSource = dsDisp.Tables[0];
    ddlDisp.DataBind();

    ddlDisp.Items.Insert(0, "<----Select---->");
    ddlDisp.Focus();
}

protected void ddlDisp_SelectedIndexChanged(object sender, EventArgs e)
{
    if (ddlDisp.SelectedIndex != 0)
    {
        String strConnString = ConfigurationManager.ConnectionStrings["CallcenterConnectionString"].ConnectionString;

        SqlConnection con = new SqlConnection(strConnString);
        SqlCommand cmd=new SqlCommand();
        SqlDataAdapter sda = new SqlDataAdapter();
        DataSet dsSubDisp = new DataSet();

        using (cmd = new SqlCommand("Select distinct CallType,Disposition,SubDisposition,Format from  Loy_DispMstr where CallType=@CallType and SUBFormat=@Format and Disposition = @disposition", con))
        {
            cmd.Parameters.AddWithValue("@CallType",ddlCalltype.SelectedValue);
            cmd.Parameters.AddWithValue("@Format", ddlFormat.SelectedValue);
            cmd.Parameters.AddWithValue("@disposition", ddlDisp.SelectedValue);
            con.Open();
            cmd.ExecuteNonQuery();
        }
        sda.SelectCommand = cmd;
        sda.Fill(dsSubDisp);
        {
            ddlSubdisp.DataTextField = "SubDisposition";
            ddlSubdisp.DataValueField = "SubDisposition";
            ddlSubdisp.DataSource = dsSubDisp.Tables[0];
            ddlSubdisp.DataBind();

            ddlSubdisp.Items.Insert(0, "<----Select---->");
            ddlSubdisp.SelectedIndex = 0;
            ddlSubdisp.Focus();

            ddlDisp.Items.Insert(1, "ADD NEW VALUE");
            ddlDisp.SelectedIndex = 1;
            ddlDisp.Focus();
        }
    }

    if (ddlDisp.SelectedItem.Text == "ADD NEW VALUE" )
    {
        TextBox1.Visible = true;
        TextBox2.Visible = true;
    }
}

protected void ddlSubdisp_SelectedIndexChanged(object sender, EventArgs e)
{
    String strConnString = ConfigurationManager.ConnectionStrings["CallcenterConnectionString"].ConnectionString;

    SqlConnection con = new SqlConnection(strConnString);

    SqlDataAdapter sda = new SqlDataAdapter();
    DataSet dsOut = new DataSet();

    SqlCommand cmd = new SqlCommand("select PID,Memberstatus,calltype,format,disposition,subdisposition, man_data,creation_date,createdby,updation_date,updatedby from Loy_SubPlaceholder");
    cmd.Connection = con; 
    sda.SelectCommand = cmd;
    sda.Fill(dsOut);
    ddlDisp.DataSource = dsOut.Tables[0];
    ddlDisp.DataValueField = "subdisposition";
    ddlDisp.DataTextField = "subdisposition";
    ddlDisp.DataBind();
    con.Open();

    cmd.ExecuteNonQuery();
}

存储过程：

if @flag = '1'
begin
Select Formatid,Formatdetail,dispformat  From loy_Formatdetail with (nolock)
Where isactive='1' and memberstatus = 'Member' order by FormatDetail
end

if @flag = '2'
begin
Select DISTINCT Disposition from CallCenter..Loy_DispMstr 
where CallType=@CallType and SUBFormat=@Format
end

if @flag = '3'  
begin  
Select distinct CallType,Disposition,SubDisposition,Format from  Loy_DispMstr
where CallType=@CallType and SUBFormat=@Format and Disposition = @disposition
end

在第一段代码中：

cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "sp_whatevername";
cmd.Parameters.AddWithValue("@CallType", ddlCalltype.SelectedValue);
cmd.Parameters.AddWithValue("@Format", ddlFormat.SelectedItem.Text);
cmd.Parameters.AddWithValue("@flag", "1");

在ddlDisp_SelectedIndexChanged中：

using (SqlCommand cmd = new SqlCommand("sp_whatevername", con)) {
      cmd.CommandType = CommandType.StoredProcedure;

      cmd.Parameters.AddWithValue("@CallType",ddlCalltype.SelectedValue);
      cmd.Parameters.AddWithValue("@Format", ddlFormat.SelectedValue);
      cmd.Parameters.AddWithValue("@disposition", ddlDisp.SelectedValue);
      cmd.Parameters.AddWithValue("@flag", "1");

      con.Open();
      cmd.ExecuteNonQuery();
    }

我已使用Parameter as flag更新代码。现在你SP应该有这个参数，并且从你的特定条件你需要传递特定的标志。通过这种方式，您可以从特定于标志的查询中获得结果。

希望这有帮助。
