<範例>
Table: [員工資料表]
欄位: [主管], [員工]

需求是: 當輸入一個員工姓名, 要把該員工下面所有階層的員工都Show出來

SQL語法:
 

WITH [員工資料表new] AS (

--找出 [主管] 為 某人的資料當作 依據

SELECT [主管], [員工]

FROM [員工資料表]

WHERE [主管] = 'XXXX'



UNION ALL



--之後以 上面查出的結果 為依據遞迴查詢

SELECT e.[主管], e.[員工]

FROM [員工資料表] e

INNER JOIN [員工資料表new] ecte ON ecte.[員工] = e.[主管]

)

SELECT *

FROM [員工資料表new]

自從上次調整 server 2008 R2 SSL 設定之後
http://blog.uwinfo.com.tw/auth/article/darren/324
調整一堆reg設定, 好不容易最後到達 A 等級

然而最近讓一家PCI認證公司做弱點掃描，他要求我把 3DES 及 TLS1.0關掉  才肯給證書
於是我就調整以下的 reg

Windows Registry Editor Version 5.00



[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\Triple DES 168]

"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\SecurityProviders\Schannel\Protocols\TLS 1.0\Server]

"Enabled"=dword:00000000

重開機，發生一個小災難，就是遠端登入(RDP) 進不去，查了一下，發現是 server2008 R2 的遠端登入是 TLS 1.0 連線
需要上 KB3080079 才能解決，但遠端都進不去了，要如何 patch
本來想說跑一趟機房，但太麻煩，於是上網查一下，發現其實可以用 PS command 方式做遠端 windows update
幸好網路上有一些這種UI工具可以做遠端管控  例如  batchpatch 
於是下載執行遠端作 patch 之後，重開機就可以遠端登入啦，省了跑機房的功夫

題外話  batchpatch 這工具蠻不錯的

#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;
 

<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)
