簡易OA漫談之工作流設計（DB實現）

本文轉載自查看原文 2012-08-24 12:10 6044 工作流/ OA/ 理論與分析

好久沒寫博客，上一篇沒想到大家討論還挻熱烈，非常感謝大家關注和提出的一些建議和意見。

大家關注的還是兩點：

1、現實流程會復雜得多;

2、流程平台需要復雜的設計（作圖）工具。

我想說的是我這里不是做一個“大而全”的工作流平台，只是從最基本的地方入手，通過這樣一些測試，讓初學者發現工作流的一些原理。

了解這些原理后，你使用各種平台（如K2）開發就會清楚一些。

上篇算是一個概要設計，這篇簡單的做一個數據庫實現，本實現暫不包括“規則處理”，即由調用端決定下一手步驟和處理人。

兄弟剛離職，現在正找工作，關乎一家人是否有飯吃，所以時間不多，寫得很粗糙，大家還請原諒則個！

用的sql server.

1、先建一個數據庫MyData

2、執行一下結構腳本

3、執行一下數據腳本

View Code

4、發起一個流程

exec usp_FlowStart 1,1,1,2,'2,3',null

參數解釋：

@FlowID int,--流程模板編號
@UserID int,--流程用戶
@ApplyUserID int,--流程申請用戶
@NextStepID int,--下一步驟
@OwnerUserIDStr varchar(500),--多個下手審批人，以‘,’分隔
@Data nvarchar(max) --表單數據，xml格式

5、讀一下任務信息

查看應該可以看到FlowInstance一條數據，這是流程實例主表。

查看應該可以看到FlowActionTrace三條數據，即申請已辦一條，待辦兩條，為什么待會是兩條，因為上面的參數

'2,3'就表示下一步處理人是兩個。

select * from dbo.FlowInstance
select * from dbo.FlowActionTrace

6、執行一個待辦提交

exec usp_FlowSubmit 3,3,3,0,'3/2,3',null

參數解釋：

@TraceID int,--flowactiontrace的id，選擇一個submittime 為null的記錄的id
@AcionID int,--操作編號，就是做的是哪種操作，一般1代表同意提交
@SubmitUserID int,--提交人編號
@IsEnd int,--是否結束步驟
@NextStr varchar(2000),--'1/3,4;3/5,6'這個結構表示“下一步驟編號/處理人編號串;下一步驟編號/處理人編號串”
@Data nvarchar(max)--表單數據，xml格式

大家會覺得組裝下一步驟和下一步操作人很麻煩，我們做了組件后會使用更好結構的屬性。

下和篇如果有興趣就做一個簡單dll和website demo,以便跑跑看。
