由於匯入91訂單，如果是一筆一筆抓，會耗費比較久的時間
下列寫法是，開兩條 thread 平行處理，可以節省約一半時間

改用 NSwag 時直接 Copy 舊專案，發現找不到 AddOpenApiDocument 和 UseOpenApi 以及 UseSwaggerUi3 如下圖:
找了一些文件，要求安裝套件，都沒有用，後來發現在 Dependencies 的 Packages 直接新增 NSwag.AspNetCore 即可
不要用 NuGet Package Manager 哦...

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);

康是美出貨印單犯下的錯誤,這邊寫給未來新進同仁注意,出貨印單時發生訂單明細品項箱數與總數量不相符的問題,
測試之後發現是記錄原始訂單上傳log table [OrderFromCosmed Log] ,在撈出該筆訂單品項資料時,資料庫物件
下select條件時發生失誤,以下是程式碼:有問題的程式碼我以#號標記
說明:已上程式是在撈出訂單品項資料時要對康是美印單用.txt sample檔裡面的字串作取代最後再列印,發生問題的程式碼,
主要是撈出該筆訂單品項時,使用資料庫物件的方法GetDataRowAndReturnSelfOrNothing()時,只下訂單品項id而沒有下
該筆訂單編號,導致撈出來的資料是其他訂單的同品項資料,進而導致數量箱數不符合的狀況發生!!

SELECT cast(ProductID AS NVARCHAR ) + ',' from [Order Details]
where OrderID = '10248'
FOR XML PATH('')
參考: http://www.dotblogs.com.tw/kevinya/archive/2012/06/01/72553.aspx
EX:
SELECT ',' + ltpid
FROM V_ltp_main WHERE ltpkind = 2
FOR XML PATH('')
STUFF ( character_expression , start , length ,character_expression )
下列範例會傳回從第一個字串 (abcdef) 中，從位置 2 (b) 開始，刪除三個字元所建立的字元字串，且會在刪除點插入第二個字串。
SELECT STUFF('abcdef', 2, 3, 'ijklmn')http://technet.microsoft.com/zh-tw/library/ms188043(v=sql.105).aspx
