#專案： 紅科

使用 SQL Server 管理介面設定欄位權限時要很小心陷井. 如下圖,
1. Col2 和 Id 欄位沒有被授予也沒有被拒絕.
2. 若是設定 Col2 欄位為授予, Id 欄位沒有做任何的修改.
3. 存檔後, Id 欄位會被拒絶存取.

 
以上的情況是用以下 SQL 生成:

GRANT SELECT ON OBJECT::S3..test TO webuser;
Deny SELECT ON OBJECT::S3..test(Col1) TO webuser;
 

jQuery 的參數提示總是 a, b, c 的看不懂 ? 請參考下圖:



上圖是引用 jquery-2.2.4.js 的結果.

下圖是引用 jquery.min.js 的結果.

大家會使用 jquery.min.js 的主要原因是, 主要是檔案大小"大幅縮小" 剩下 25% 左右. 但是....

減少的 75% = 270K, 而且只有第一次載入時會真的下載檔案.

所以要用哪一個呢 ? 這就留給你判斷了...

<a class="del" href="#" data-yano="1250453286" data-pdno="04360003">

    <img src="/TC/template/Shopping/images/del.png" alt="">

</a>

用 $(".del").data("pdno") 會回傳 4360003
被這個搞了好久..

要避免這個問題, 可以使用 attr  來代替 data
$(".del").attr("data-pdno")

由於從欄位抓出的值 雖然是由逗點分隔 但整體資料容易被當成一組單一字串
例如
Table
#SomeTable
欄位 :
Id  MemberIds
值
1 12,30,58
2 45,68,88

想要篩選  where member_Id in (select MemberIds from SomeTable  where Id = 2)
會被當成  Id in ('45,68,88')  文字跟整數無法被篩選

解決方法之一

  create table #SomeTable (Id int,MemberIds nvarchar(30))
  insert into #SomeTable (Id,MemberIds) values (1,'12,30,58')
  insert into #SomeTable (Id,MemberIds) values (2,'45,68,88')
  select * from #SomeTable

  create table #TargetTable (Id int,member_Id  nvarchar(30))
  insert into #TargetTable (Id,member_Id ) values (1,12)
  insert into #TargetTable (Id,member_Id ) values (2,30)
  insert into #TargetTable (Id,member_Id ) values (3,45)
  insert into #TargetTable (Id,member_Id ) values (4,58)      
  insert into #TargetTable (Id,member_Id ) values (5,68)
  insert into #TargetTable (Id,member_Id ) values (6,88)
  select * from #TargetTable

DECLARE @MemberIds nvarchar(200);DECLARE @SQLString nvarchar(200);
select  @MemberIds =MemberIds  from #SomeTable(nolocK) where Id = 2
SET @SQLString = N' select * from #TargetTable   where member_Id in (' + @MemberIds  + ')' ;  
EXECUTE sp_executesql @SQLString

將整體都當成字串   就可以執行了

如果用逗點隔開如果用逗點隔開的是字串
如:
Hi,Im,String
可以先把它加上單引號
select '''' + Replace(MemberIds ,',','''' +',' + '''') + '''' from #SomeTable 






 

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)

由於早期網站都是VB.net寫的，若是直接換成 C#，就會耗費很多時間在轉換程式上
因此 ASP.NET 特別可以在同一網站同時寫 vb 跟 C#，方式是在 web.config compilation 加上設定

    <compilation debug="true" defaultLanguage="c#" targetFramework="4.0">

     <codeSubDirectories>

        <add directoryName="VB_Code"/>

        <add directoryName="CS_Code"/>

     </codeSubDirectories>

    </compilation>

也就是 VB.NET 的 code 就放到 ~\APP_Code\VB_Code 目錄
C# 的 code 就放到 ~\APP_Code\CS_Code 目錄
這樣做有兩點要注意
1.  Namespace 的命名，最好不要互相衝突, 要能夠區分出來
2.  VB_Code 與 CS_Code 放的位置有很大的影響, 因為牽涉到 compiler的先後順序，因為 VB_Code 在 CS_Code 在前面，所以 CS_Code可以叫用 VB_Code下的程式，但是 VB_Code 卻不能叫用 CS_Code 的程式，如果希望 VB_Code可以叫用 CS_Code的程式，就把設定換過來

    <compilation debug="true" defaultLanguage="c#" targetFramework="4.0">

     <codeSubDirectories>

        <add directoryName="CS_Code"/>

<add directoryName="VB_Code"/>

     </codeSubDirectories>

    </compilation>

缺點就是反過來 CS_Code不能使用 VB_Code的程式

基本上，若是舊的程式碼都在VB_Code 那就把 VB_Code 放到前面

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();

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

#微軟的排程備份真是有夠爛沒有辦法用介面一鍵搞定

比較特別的地方，都在下面的程式碼後面的註解
​

Response.Write(Convert.ToInt32("94"));

Response.Write("<br/>");

Response.Write(Convert.ToInt32(94.5)); //會四捨六入五成雙

Response.Write("<br/>");

Response.Write((94.5).ToString("N0")); //會四捨五入

Response.Write("<br/>");

Response.Write((95.5).ToString("N0")); //會四捨五入

Response.Write("<br/>");

Response.Write(Convert.ToInt32(null)); //會 return 0

Response.Write("<br/>");

Response.Write(Convert.ToInt32("94.55")); //會有 exception 要先轉成 double 之類的數值

Response.Write("<br/>");

今天遇到客戶的 DB  使用空間滿了. 有  "Active Transaction" 

什麼事十日都不能做, 只好刪掉所有的 Session. 使用的 SQL 如下:

SQL 2012
USE [master];

DECLARE @kill varchar(8000) = '';  
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), session_id) + ';'  
FROM sys.dm_exec_sessions
WHERE database_id  = db_id('MyDB')

EXEC(@kill);


​
For MS SQL Server 2000, 2005, 2008
USE master;

DECLARE @kill varchar(8000); SET @kill = '';  
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'  
FROM master..sysprocesses  
WHERE dbid = db_id('MyDB')

EXEC(@kill);
