More on SQL Server Service Broker

2011-01-30T03:28:00Z

In earlier posts I already blogged about creating some simple queuing solutions with SQL Server Service Broker. Last week I spend some time actually implementing my research in a customer project and of course ran into two 'interesting' issues.

It is possible for the Service Broker to somehow die on you, whilst appearing to be up and running and with RETENTION=ON sent message appear to be in the queue.

When using the SQL Profiler it becomes clear that messages don't get processed because the Service Broker is not enabled.

You can use the following statement to enable Service Broker:

alter database PFA_DATA set ENABLE_BROKER

I had to do it on two machines and on of them gave me the following error:

Msg 9772, Level 16, State 1, Line 2
The Service Broker in database "PFA_DATA" cannot be enabled because there is already an enabled Service Broker with the same ID.
Msg 5069, Level 16, State 1, Line 2
ALTER DATABASE statement failed.

So instead I used:

alter database PFA_DATA set NEW_BROKER

After this the Service Broker was up and running and message started getting delivered.

If the query takes extremely long to complete restart SQL Server and try again.

One potential cause for this is when you restore a database.
In my earlier post I just blatantly used WITH CLEANUP to avoid getting EndDialog messages.
The documentation however states:

WITH CLEANUP
Remove all messages and catalog view entries for this side of the conversation without notifying the other side of the conversation. Microsoft SQL Server drops the conversation endpoint, all messages for the conversation in the transmission queue, and all messages for the conversation in the service queue. Use this option to remove conversations which cannot complete normally. For example, if the remote service has been permanently removed, you use WITH CLEANUP to remove conversations to that service.

So use this sparingly.

I've discovered a much cleaner way to handle it.
When sending a message you can use "END CONVERSATION @dialog" to specify that as far as the sender is concerned the dialog is over. In other words: a fire and forget message.
When the receiving side of the conversation receives the messages and performs its "END CONVERSATION" statement, Service Broker will detect that no acknowledgement (EndDialog) needs to be send.

[转]Android试验:如果View的ID相同会出现什么效果？

2011-01-18T06:26:00Z

1.实验：通过布局编辑器强行指定两个button id相同，然后在代码中通过findViewById()获得句柄后修改其文本。
实验结果：只有一个button的文本变化了，另一个不受影响。
2.实验：主布局只放一个linearLayout，代码中动态的new 一个button，然后同过Layout.addView()多次重复添加。
实验结果：发现程序直接报错不让运行了。
3.实验：主布局放置两个linearLayout，代码中new一个button后，通过Layout.addView()分别添加到两个不同布局中去。
实验结果：发现程序直接报错不运行了。
4.实验：Activity主布局放置一个按钮Id为btn001，创建一个对话框，其布局中也放置一个按钮，id同样为btn001，在Activity以及Dialog的onCreate函数中都通过findViewById来查找btn后修改文本。
实验结果：两个按钮的文本都修改成了各自的文本，互不影响。
5.实验：Activity中通过new创建一个button；将新创建的button添加到Activity上；创建一个对话框，将这个button再添加到对话框上。
实验结果：程序运行出错。

结论：
1.同一工程中的View的ID可以一样，在R文件中，同样的ID只会生成一个数据项。
2.两个同ID的View被同一个View显示时，通过findViewById只能访问其中一个。
3.同一个View(即new出来的句柄)只能被一个View管理，不能多次添加到另一个View或者另外多个View，否则程序运行出错。

父子关系排序，无确定根节点

2010-03-15T02:51:00Z

需要更新一批数据，需要按照父子关系依次更新，前提是如果有父节点一定要先更新父节点。

这个算法感觉有些麻烦，不知是否有更好的方法

示例数据：

ID,ParentID
(1, -1),(5, -1),(323, 32), (555, 55),(55, 5),(87, 8),(633, 63),(63, 6),(2, -1),(3232, 323)

排序后的结果
1，5，55，555，323，3232，87，63，633，2

var list = new List<KeyValuePair<int,int>>
               {
                   new KeyValuePair<int, int>(1, -1),
                   new KeyValuePair<int, int>(5, -1),
                   new KeyValuePair<int, int>(323, 32),
                   new KeyValuePair<int, int>(555, 55),
                   new KeyValuePair<int, int>(55, 5),
                   new KeyValuePair<int, int>(87, 8),
                   new KeyValuePair<int, int>(633, 63),
                   new KeyValuePair<int, int>(63, 6),
                   new KeyValuePair<int, int>(2, -1),
                   new KeyValuePair<int, int>(3232, 323)
               };
var testList = GetSortedList(list);

排序

        private static List<KeyValuePair<int, int>> GetSortedList(IEnumerable<KeyValuePair<int, int>> list)
        {
            var tempList = new List<KeyValuePair<int, int>>();
            tempList.AddRange(list);
            var result = new List<KeyValuePair<int, int>>();
            foreach (var keyValuePair in list)
            {
                if (!tempList.Contains(keyValuePair)) continue;
                var parentList = new List<KeyValuePair<int, int>>();
                BuildParent(keyValuePair.Value, ref parentList, list);
                for (var i = parentList.Count - 1; i >= 0; i--)
                {
                    if (!tempList.Contains(parentList[i])) continue;
                    result.Add(parentList[i]);
                    tempList.Remove(parentList[i]);
                }
                result.Add(keyValuePair);
                tempList.Remove(keyValuePair);

                var childList = new List<KeyValuePair<int, int>>();
                BuildChild(keyValuePair.Key, ref childList, list);
                for (var i = 0; i < childList.Count; i++)
                {
                    if (!tempList.Contains(childList[i])) continue;
                    result.Add(childList[i]);
                    tempList.Remove(childList[i]);
                }
            }
            return result;
        }

构建孩子列表和父亲列表

        private static void BuildChild(int parentId, ref List<KeyValuePair<int, int>> newlist,
                                                      IEnumerable<KeyValuePair<int, int>> list)
        {
            var children = from keyValuePair in list
                           where keyValuePair.Value == parentId
                           select keyValuePair;
            foreach (var child in children)
            {
                newlist.Add(child);
                BuildChild(child.Key, ref newlist, list);
            }
        }
        private static void BuildParent(int childId, ref List<KeyValuePair<int, int>> newlist,
                                                      IEnumerable<KeyValuePair<int, int>> list)
        {

           var parents = from keyValuePair in list
                                  where keyValuePair.Key == childId
                                   select keyValuePair;
             foreach (var parent in parents)
                {
                 newlist.Add(parent);
                 BuildParent(parent.Value, ref newlist, list);
                }


        }

如果有固定的根节点就好排序多了

            var list = new List<KeyValuePair<int,int>>
                           {
                               new KeyValuePair<int, int>(1, -1),
                               new KeyValuePair<int, int>(5, -1),
                             new KeyValuePair<int, int>(55, 5),
                               new KeyValuePair<int, int>(17, 1),
                               new KeyValuePair<int, int>(558, 55),
                               new KeyValuePair<int, int>(174, 17),
                               new KeyValuePair<int, int>(2, -1),
                                                      };
            var result= new List<KeyValuePair<int, int>>();
            BuildParentChildList(-1, ref result, list);

     private static  void BuildParentChildList(int parentId,ref List<KeyValuePair<int, int>> targetList ,
                                                           List<KeyValuePair<int, int>> sourceList)
        {
            var dic = from source in sourceList
                           where  source.Key== parentId
                           select source;
            foreach (var source in dic)
            {
                var childParentId = source.Key;
                targetList.Add(source);
                BuildParentChildList(childParentId, ref targetList, sourceList);
            }
        }
