抓出每個 Block_Id 中, End_Date 最小的資料.

語法 A:
With TempBlock as (
Select *, 
ROW_NUMBER() OVER(PARTITION BY B.Block_Id ORDER BY B.End_Date, B.Id) AS rk 
from BlockData B Where IsDelete = 'N' and End_Date >= getDate())
Select * from TempBlock Where rk = 1

語法 B:

#專案： 紅科

我想大家一定會遇到要把資料匯出成 Excel 的需求. 以現有的工具, 大家想到作法大概都是先把資料放到一個 datatable 之中, 後叫用 UW.ExcelPOI.DTToExcelAndWriteToClient 就結束了.

前兩天遇到一個需求, 輸出的 Excel 要加上表頭, 如下圖



於是乎把  UW.ExcelPOI.DTToExcelAndWriteToClient 做了一些擴充, (其實應該說是幫 DTToWorkSheet 做了擴充), 過程如下.

1. 需求: 一個可以快速填入欄位的 Sub (method or function)
A. 每一個 Cell 可以設定內容(文字), 字型大小, 跨欄數, 對齊方式. (其它的未來再來擴充, 例如顔色).
B. 每一個 Row 由 Cell 組成, 由左到右.
C. 一次可以填多個 Row

2. 實作:
A. 先定義 Cell

    Public Class Cell

        Public Content As String

        Public Colspan As Int32 = 1

        Public Alignment As NPOI.SS.UserModel.HorizontalAlignment

        Public FontHeightInPoints As Int32 = 0



        Sub New(Content As String, Optional Colspan As Int32 = 1,

                Optional Alignment As NPOI.SS.UserModel.HorizontalAlignment = NPOI.SS.UserModel.HorizontalAlignment.General,

                Optional FontHeightInPoints As Int32 = 0)

            Me.Content = Content

            Me.Colspan = Colspan

            Me.Alignment = Alignment

            Me.FontHeightInPoints = FontHeightInPoints

        End Sub

    End Class

B. Row 的格式: 我想最直的覺的就是 List(of Cell) 了吧.

C. 多個 Row 的表示法: List(Of List(Of Cell))

D. 來把 Cell 填入 WorkSheet  吧, 

Public Shared Sub AddRows(WS As HSSFSheet, ltRows As List(Of List(Of Cell)), ByRef StartRow As Int32)

共有三個參數: WS  和 ltRows 應該不用解釋了. 最後一個 StartRow 用來指定插入資料的開始 Row.

E.  完整程式碼: (程式碼不看沒關係, 但要跳到 F. 重點講解哦)

Public Shared Sub AddRows(WS As HSSFSheet, ltRows As List(Of List(Of Cell)), ByRef StartRow As Int32)

        Dim WR As HSSFRow

        If ltRows IsNot Nothing Then

            For Each ltRow As List(Of Cell) In ltRows

                WR = WS.CreateRow(StartRow)

                Dim C As Int32 = 0

                For Each cell As Cell In ltRow

                    Dim ic As NPOI.SS.UserModel.ICell = WR.CreateCell(C)

                    ic.SetCellValue(cell.Content)



                    Dim cs As NPOI.SS.UserModel.ICellStyle = WS.Workbook.CreateCellStyle()

                    cs.Alignment = cell.Alignment

                    If cell.FontHeightInPoints > 0 Then

                        Dim oFont As NPOI.SS.UserModel.IFont = WS.Workbook.CreateFont()

                        oFont.FontHeightInPoints = cell.FontHeightInPoints

                        cs.SetFont(oFont)

                    End If



                    ic.CellStyle = cs



                    If cell.Colspan > 1 Then

                        WS.AddMergedRegion(New CellRangeAddress(StartRow, StartRow, C, C + cell.Colspan - 1))

                        C += cell.Colspan - 1

                    End If

                    C += 1

                Next



                StartRow += 1

            Next

        End If

    End Sub

F. 重點講解:
這個 function 在實作時有兩個卡點:
1. 如何合併欄: 

WS.AddMergedRegion(New CellRangeAddress(StartRow, StartRow, C, C + cell.Colspan - 1))

2. 如何設定字型大小和對齊方式:

                    Dim cs As NPOI.SS.UserModel.ICellStyle = WS.Workbook.CreateCellStyle()

                    cs.Alignment = cell.Alignment

                    If cell.FontHeightInPoints > 0 Then

                        Dim oFont As NPOI.SS.UserModel.IFont = WS.Workbook.CreateFont()

                        oFont.FontHeightInPoints = cell.FontHeightInPoints

                        cs.SetFont(oFont)

                    End If



                    ic.CellStyle = cs

這裡有件有有趣的事, 我一開始是這樣寫的.

ic.CellStyle.Alignment = cell.Alignment

結果是整個 WorkSheet 的對齊方式都被改了. 我猜當 WorkSheet 初建立時, CellStyle 都是用同一個. 所以改任一個 cell 的 CellStyle 會同時改到所有 cell 的.

G. 使用方式:

        Dim ltHeader As New List(Of List(Of UW.ExcelPOI.Cell))

        Dim ltLine As New List(Of UW.ExcelPOI.Cell)

        ltLine.Add(New UW.ExcelPOI.Cell(DB.SysConfig.SYSTEM_NAME & "應收明細表", 16,

                                        NPOI.SS.UserModel.HorizontalAlignment.Center, 28))

        ltHeader.Add(ltLine)



        '第二行

        ltLine = New List(Of UW.ExcelPOI.Cell)

        ltLine.Add(New UW.ExcelPOI.Cell("期間: " & Me.txtbl_date_s.Text & " ~ " & Me.txtbl_date_e.Text, 10,

                                        NPOI.SS.UserModel.HorizontalAlignment.Left, 20))

        ltLine.Add(New UW.ExcelPOI.Cell("製表日期: " & Now.ToString("yyyy-MM-dd"), 6,

                                        NPOI.SS.UserModel.HorizontalAlignment.Right, 20))

        ltHeader.Add(ltLine)



        UW.ExcelPOI.DTToExcelAndWriteToClient(newdt, ltHeader:=ltHeader)

由於工作排程往往有數十個甚至百來個 因此需要一個方法能快速備份及移轉到其他 server 的方法
查了一下，好像也只能這樣做

---- 使用指令把全部排程匯出 ----
參考網址
https://msdn.microsoft.com/en-us/library/windows/desktop/bb736357%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396

schtasks /query /XML > all_tasks.xml  
schtasks /query /FO CSV /V >sched_tasks.csv

** xml 比較有用,可以用來匯入到其他server排程，但還要額外處理才能匯入
** csv 只是用來看看目前有哪些排程 可以用來做報表看看
** 這些是全部排程，還要特別處理把 Microsoft 及其他軟體建的排程移除

--------------------------------------------------------------

----如何匯入工作排程到其他 server --------

** 需再寫程式把 all_tasks.xml 拆解成所有排程的單一 xml
   並且生成指令 bat

** 注意 xml 必須是 UTF-16 (unicode) 
   因為 "schtasks /query /XML > all_tasks.xml"產生 xml 是 ansi 

參考網址
https://serverfault.com/questions/325569/how-do-i-import-multiple-tasks-from-a-xml-in-windows-server-2008
** /TN "排程名稱" --- 排程名稱可以是路徑名 
D:\>schtasks.exe /create /TN "\2016JOB\Global\CountryMonthlyStats" /XML "D:\one_task.xml"
** 下面程式碼只是下面程式碼只是參考 還沒實作過
=====================================

var taskXML = new XmlDocument();
taskXML.Load(@"d:\temp\schedtasksBackup.xml");
var batbody = new StringBuilder();

XmlNodeList tasks = taskXML.DocumentElement.GetElementsByTagName("Task");

string strFileName = "d:\\temp\\Task";

for (int i = 0; i < tasks.Count; i++) {
    string onetaskXML = tasks[i].OuterXml;

    //Create the New File. With a little more extra effort
    //you can get the name from a comment above the task -> 應該把註解裡的名稱抓出
    XmlWriter xw = XmlWriter.Create(strFileName + "_" + (i+1) + ".xml");
    batbody.AppendLine(string.Format("schtasks.exe /create /TN \"{0}\" /XML \"{1}\"", "Task " + (i+1) + " Name", strFileName + "_" + (i+1) + ".xml"));

    //Write the XML
    xw.WriteRaw(onetaskXML.ToString());
    xw.Close();

    // Write a bat to import all the tasks
    var batfile = new System.IO.StreamWriter("d:\\temp\\importAllTasks.bat");
    batfile.WriteLine(batbody.ToString());
    batfile.Close();

}
=====================================

客戶要求
1. 檔案只能放在 Firewall 內的後台用 Web server (Server A).
2. 使用者只能存取 DMZ 的 Web server (Server B).
3. Server B 只能用 HTTP 通過 Firewall 向 Server A 要資料.(i.e.  Server B 不能掛戴 Server A 的目錄成為虛擬目錄)

所以在 Server B 上面建立了一支程式用 HTTP 的方式讀取 Server A 的檔案再寫出去.

例如, http://ServerB/Upload/test.pdf 會讀取 http://ServerA/Upload/test.pdf 再送到 Client 端

namespace WWW.Controllers

{

    public class UploadController : Controller

    {

        // GET: Upload

        public void Index(string Filename)

        {

            //Create a stream for the file

            Stream stream = null;



            //This controls how many bytes to read at a time and send to the client

            int bytesToRead = 10000;



            // Buffer to read bytes in chunk size specified above

            byte[] buffer = new Byte[bytesToRead];



            string url = "http://admin-dev.nanya.bike.idv.tw/newnanyaback/Upload/" + Filename;



            // The number of bytes read

            try

            {

                //Create a WebRequest to get the file

                HttpWebRequest fileReq = (HttpWebRequest)HttpWebRequest.Create(url);



                //Create a response for this request

                HttpWebResponse fileResp = (HttpWebResponse)fileReq.GetResponse();



                if (fileReq.ContentLength > 0)

                    fileResp.ContentLength = fileReq.ContentLength;



                //Get the Stream returned from the response

                stream = fileResp.GetResponseStream();



                // prepare the response to the client. resp is the client Response

                var resp = HttpContext.Response;



                if (Filename.ToLower().EndsWith(".png") ||

                    Filename.ToLower().EndsWith(".jpg") ||

                    Filename.ToLower().EndsWith(".jpeg") ||

                    Filename.ToLower().EndsWith(".gif")

                    )

                {

                    resp.ContentType = "image";

                }

                else

                {

                    //Indicate the type of data being sent

                    resp.ContentType = "application/octet-stream";



                    //Name the file

                    resp.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(Filename, Encoding.UTF8) + "\"");

                }



                resp.AddHeader("Content-Length", fileResp.ContentLength.ToString());



                int length;

                do

                {

                    // Verify that the client is connected.

                    if (resp.IsClientConnected)

                    {

                        // Read data into the buffer.

                        length = stream.Read(buffer, 0, bytesToRead);



                        // and write it out to the response's output stream

                        resp.OutputStream.Write(buffer, 0, length);



                        // Flush the data

                        resp.Flush();



                        //Clear the buffer

                        buffer = new Byte[bytesToRead];

                    }

                    else

                    {

                        // cancel the download if client has disconnected

                        length = -1;

                    }

                } while (length > 0); //Repeat until no data is read

            }

            finally

            {

                if (stream != null)

                {

                    //Close the input stream

                    stream.Close();

                }

            }

        }

    }

}

但不是這樣就好了, 在 RouteConfig.cs 中要加上:
            routes.MapRoute(
                name: "Upload",
                url: "Upload/{filename}",
                defaults: new { controller = "Upload", action = "Index", filename = UrlParameter.Optional }
            );

此外在 Web.Config 中也要加上:

  <system.webServer>
    <handlers>
      <add name="UrlRoutingHandler_Upload"
           type="System.Web.Routing.UrlRoutingHandler, 
               System.Web, Version=4.0.0.0, 
               Culture=neutral, 
               PublicKeyToken=b03f5f7f11d50a3a"
           path="/Upload/*"
           verb="GET"/>
    </handlers>
  </system.webServer>
