SQL，链接到元素功能

Question

我有两节课。 class1 的一个属性连接到 class2 的另一个属性。 这是在一个类附近的连接器的上下文菜单的帮助下完成的，它被称为“链接到元素功能”。在连接器的另一侧执行相同的操作以选择其他类的其他属性。 因此连接器直接连接两个属性而不是类本身。 我还没有找到存储此信息的表，因此我找不到适当的 SQL 来查找连接（或未连接）的属性。

 做笔记的方法

PDATA1 = '属性'

• PDATA2 = t_attribute.属性的ID
• PDATA3 = 属性名称
• PDATA4 有“是”（我不记得它的用途，所以你可以忽略它
第一个SQL：

SELECT PDATA2 FROM t_object WHERE Object_Type='Note' AND PDATA1 = 'Attribute'

会给你ID。只需将其放入另一个 SQL 中即可：

SELECT * FROM t_attribute WHERE ID = (above SQL)

并且您拥有属性详细信息。或者，如果您想找到未映射的 ID，只需将第一个找到的 ID 与现有属性 ID 进行剖析即可。

对于使用

的关联来说，有点棘手。首先，任何此类连接器都将相关信息存储在

t_connector.StyleEx

中，例如LFEP={69A30E17-23AB-4641-9573-9BDBAA988D52}L;

LF<dir>P=<guid><pos>;

连接器附加到属性/操作

<dir>

= S 或 E 表示开始（源）或结束（目标）

<guid>

=

t_attribute

或

t_operation

 的 ea_guid
  
  

<pos>

是创建链接时连接器所连接的边缘（L 或 R）。这是多余的信息，因为渲染器会将链接附加到任何相关的位置。

一个 StyleEx 属性中可以存在一个 LFSP、一个 LFEP 或两者都存在

现在您可以使用 SQL 或（我更喜欢）一个小脚本来过滤该信息，因为执行复杂的 SQL 字符串操作不是我的专长。

[在查询顶部附近，您将看到一个文字包名称“Workday ETL Mapping”。 该包定义了查询的范围；它包含几个定义了 ETL 源/目标映射的图表。]
