元素类型H和R的行是图像中的行。 T类型的行稍后已添加。

这个结构实际上是一个所有LEAFS都为R的树 - 类型和其他节点，它们是父节点H - 类型。

每个H - 类型节点应该有一个对应的T类型节点，并且最后会添加这些节点。

EXPECTED OUTPUT:

我的问题是我试图按以下顺序获取所有元素（它们在图像中显示的方式，从上到下，但每个H线必须由T线关闭）：

我只想简单地按ORDER BY特定列，但我似乎无法找到方法。我不确定，但我有一种感觉，我必须以递归的方式遍历表格，以便将TOTAL行放在应该位于的位置。

我的查询很简单，不是重点，我正在努力找到正确的顺序。

SELECT
    ID,
    Element,
    Type,
    LEVEL,
    ElemOrder,
    Header,
    Total
FROM myTable

Answer 1

这是类型字段的基本排序，您可以添加其他排序条件

试试这个：

SELECT
  ID,
  Element,
  Type,
  LEVEL,
  ElemOrder,
  Header,
  Total
FROM myTable
ORDER BY
CASE 
  when type = 'H' then 1
  when type = 'R' then 2
  when type = 'T' then 3
end

Answer 2

如果没有先到树的每个节点，就无法生成层次排序。这是因为表的树/行的每个节点仅包含有关其自身及其直接父节点的信息;如果没有完整的“地址”描述行在最终报告中的位置，则无法应用排序。

幸运的是，我们可以使用ASCII字符串的排序方式，使用基于集合的逻辑快速生成地址。递归是没有必要的;我们所要做的就是：

查找树的根（在此特定情况下，不带父项的标题行（HEADER is NULL）并构建根的地址。
查找具有父地址值的所有节点，并将父地址复制到子节点，附加有关子节点的其他信息
重复步骤2，直到所有节点都填充了一个地址。

在您的具体情况下，我通过将上述内容仅应用于标题行来简化操作;叶子和总数在单独的陈述中更新。

这将在SQL Server 2008中运行。
