SQL Server CTE递归次数过多

我需要一些帮助，以找出构建此查询的最佳方法，而且我认为我认为CTE是最好的主意。如果有更好的方法，我愿意接受其他建议。

此应用程序具有几种不同的对象类型。我当前关注的对象的简单层次结构如下：Group -> Catalog(s) -> Item(s) and Feature(s) -> Features (items also connect to features) -> Feature Values。这些对象中的每一个也都进行了版本控制，因此它们可以是第一个版本，也可以是多个深度版本。 （提供此层次结构只是为了了解要实现的目标。

我要处理的数据都包含在History表中。该表包含以下列：HistoryID, HistoryObjectID, HistoryObjectCode, HistoryObjectTypeID, HistoryMessage, HistoryObjectTypeObjectID, Timestamp, ParentHistoryID, ParentObjectID, HistoryObjectGuid, NetworkID

  • HistoryObjectID是一个ID，该ID外键到创建该行的对象表（如组，目录等）
  • HistoryObjectCode是对象表中的另一个标识符，并在UI中使用
  • HistoryObjectTypeID是与对象类型（即组，目录等）相对应的枚举
  • 消息应该是不言自明的
  • HistoryObjectTypeObjectID（坏名）是对象的主键
  • 时间戳-不言自明
  • ParentHistoryID-如果此历史记录是从另一个“产生”的，则填充。实际上，我们现在实际上并没有真正使用它。
  • ParentObjectID-这是CTE中正在使用的当前列。它用对象“父”的主键填充。如果存在，则将其定义为对象父版本的主键。如果此版本是第一个版本，则它是父对象的主键。因此，对于目录的第一个版本，将使用包含目录的组ID进行填充。

这是我目前用于查询的内容。我的问题是在“基本情况”中返回的每一行都会发生递归：

WITH n(HistoryID, HistoryObjectID, HistoryObjectTypeID, HistoryObjectTypeObjectID, HistoryObjectCode, HistoryMessage, UserID, Timestamp, ParentHistoryID, ParentObjectID, HistoryObjectGuid) AS (
    SELECT HistoryID, HistoryObjectID, HistoryObjectTypeID, HistoryObjectTypeObjectID, HistoryObjectCode, HistoryMessage, UserID, Timestamp, ParentHistoryID, ParentObjectID, HistoryObjectGuid 
    FROM [DBName].[History] 
    WHERE HistoryObjectID = @HistoryObjectID
  UNION ALL 
    SELECT nplus1.HistoryID, nplus1.HistoryObjectID, nplus1.HistoryObjectTypeID, nplus1.HistoryObjectTypeObjectID, nplus1.HistoryObjectCode, nplus1.HistoryMessage, nplus1.UserID, nplus1.Timestamp, nplus1.ParentHistoryID, nplus1.ParentObjectID, nplus1.HistoryObjectGuid
    FROM [DBName].History as nplus1
    INNER JOIN n on n.HistoryObjectTypeObjectID = nplus1.ParentObjectID) 
  SELECT n.HistoryID, n.HistoryObjectID, n.HistoryObjectCode, n.HistoryObjectTypeID, n.HistoryMessage, n.HistoryObjectTypeObjectID, n.Timestamp, n.ParentHistoryID, n.ParentObjectID, n.HistoryObjectGuid, u.NetworkID
  FROM n INNER JOIN [CatalogBuilder].[User] u on n.UserId = u.UserId

例如，使用特定ID的以下查询运行之一将返回1653行，而在基本情况下将返回28行。如果在最终的select语句中添加distinct，则只会得到我真正感兴趣的49行。显而易见的问题是，由于不必要的递归，该查询需要花费非常长的时间才能运行。

我愿意接受有关如何执行此操作的任何建议。
