Dynamics 365 POA表记录的查询

PrincipalObjectAccess表是用于共享记录,这个表如果记录太多,会导致系统整体性能下降,最好能控制下记录数量。

如果部署的是Dynamics 365 Customer Engagement On-Premise版本,直接上数据库查询可以,执行如下T-SQL即可。

select count(*) from PrincipalObjectAccess with (nolock)

如果估计返回记录不超过5000行记录,也可以直接用Web API来查看,带上$count=true即可,实例代码如下:

https://demo.luoyong.me/api/data/v9.0/principalobjectaccessset?$select=principalobjectaccessid&$count=true

https://demo.luoyong.me/api/data/v9.0/principalobjectaccessset?$select=principalobjectaccessid&$filter=objecttypecode eq 'template'&$count=true

执行效果类似如下,如果返回的 @odata.count 元素值等于5000,请不要相信这是准确数据,请用后面的方法查看。

如果前面返回的记录数为5000,但是估计在5万条下,也可以执行使用类似如下的URL进行查询,当然如果超过5万行会报错。

https://demo.luoyong.me/api/data/v8.2/principalobjectaccessset?fetchXml=%3Cfetch%20aggregate=%27true%27%20version=%271.0%27%20mapping=%27logical%27%20distinct=%27false%27%3E%0A%C2%A0%3Centity%20name=%27principalobjectaccess%27%3E%0A%C2%A0%C2%A0%3Cattribute%20aggregate=%27count%27%20alias=%27recordscount%27%20name=%27principalobjectaccessid%27%20/%3E%0A%C2%A0%3C/entity%3E%0A%3C/fetch%3E%0A%20%20%20%20

这其实是用Web API执行如下的聚合FetchXml:

<fetch aggregate='true' version='1.0' mapping='logical' distinct='false'>
 <entity name='principalobjectaccess'>
  <attribute aggregate='count' alias='recordscount' name='principalobjectaccessid' />
</entity>
</fetch>

如果超过5万行的话怎么计数?当然我不会阻拦你自己写程序来做,但是我已经有工具了,建议你不要重复造*。参考我的博文:无依赖简单易用的Dynamics 365实体记录数计数器并能计算出FetchXml返回的记录数 。直接执行如下的FetchXml即可:

<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
 <entity name='principalobjectaccess'>
  <attribute name='principalobjectaccessid' />
</entity>
</fetch>

也可以对这个实体做筛选,类似如下的FetchXml:

<fetch version='1.0' mapping='logical' distinct='false'>
 <entity name='principalobjectaccess'>
  <attribute name='principalobjectaccessid' />
  <filter type='and'>
   <condition attribute='objecttypecode' operator='eq' value='2010' />
</filter>
</entity>
</fetch>

执行效果如下图所示:

你可能会有疑问,怎么看一个实体的ObjectTypeCode的值,根据实体的逻辑名称来查看实体的ObjectTypeCode用类似如下的URL:

https://demo.luoyong.me/api/data/v9.0/EntityDefinitions(LogicalName='account')?$select=EntitySetName,ObjectTypeCode

你可能还会问,如果根据ObjectTypeCode来看是哪个实体,用如下的URL即可:

https://demo.luoyong.me/api/data/v9.0/EntityDefinitions?$select=EntitySetName,LogicalName&$filter=ObjectTypeCode eq 2010

当然也可以将记录导出来分析,下面是一个示例,将数据生成CSV文件,然后用Excel或者导入到数据库中分析,数据分页查询请参考:Page large result sets with QueryExpression

        private static void GetAllPOA(OrganizationServiceProxy orgSvc)
{
string outPutFileName = ConfigurationManager.AppSettings["outPutFileName"];
if (!File.Exists(outPutFileName))
{
string clientHeader = $"principalobjectaccessid,principalid,objecttypecode,objectid,principaltypecode,inheritedaccessrightsmask,changeon,accessrightsmask{Environment.NewLine}";
File.WriteAllText(outPutFileName, clientHeader);
}
int queryCount = ;
int pageNumber = ;
QueryExpression pagequery = new QueryExpression("principalobjectaccess");
pagequery.NoLock = true;
pagequery.AddOrder("changedon", OrderType.Descending);
pagequery.ColumnSet = new ColumnSet("principalobjectaccessid", "principalid", "objecttypecode", "objectid", "principaltypecode", "inheritedaccessrightsmask", "accessrightsmask", "changedon");
pagequery.PageInfo = new PagingInfo();
pagequery.PageInfo.Count = queryCount;
pagequery.PageInfo.PageNumber = pageNumber;
pagequery.PageInfo.PagingCookie = null; while (true)
{
EntityCollection results = orgSvc.RetrieveMultiple(pagequery);
if (results.Entities != null)
{
foreach (var entity in results.Entities)
{
File.AppendAllText(outPutFileName, $"{entity.GetAttributeValue<Guid>("principalobjectaccessid")}," +
$"{entity.GetAttributeValue<Guid>("principalid")}," +
$"{entity.GetAttributeValue<string>("objecttypecode")}," +
$"{entity.GetAttributeValue<Guid>("objectid")}," +
$"{entity.GetAttributeValue<string>("principaltypecode")}," +
$"{entity.GetAttributeValue<int>("inheritedaccessrightsmask")}," +
$"{entity.GetAttributeValue<DateTime>("changedon").ToLocalTime().ToString("yyyy-MM-dd HH:mm:ss.fff")}," +
$"{entity.GetAttributeValue<int>("accessrightsmask")}{Environment.NewLine}");
}
}
if (results.MoreRecords)
{
pagequery.PageInfo.PageNumber++;
pagequery.PageInfo.PagingCookie = results.PagingCookie;
}
else
{
break;
}
}
}
