如何更改遞歸查詢的工作？

Question

我試圖剝離存儲過程到核心從屬列和表。我在那裏50％，需要一隻手來獲得100％的分數。

這是我所擁有的，它爲我提供了存儲過程中的核心表對象依賴關係。我需要的也是核心列對象的依賴關係。

你去那裏：你需要做的一切，都是爲了增加col_name(s.depid, s.depnumber) AS 'column'到您的CTE：

declare @ObjectName AS SYSNAME 
set @ObjectName = 'test1' 

    ;WITH Obj AS (
     SELECT DISTINCT 
      s.id AS ParentID, 
      s.DepID AS ObjectID, 
      o1.Name AS ParentName, 
      o2.Name AS ChildName, 
      QUOTENAME(sch1.name) + '.' + QUOTENAME(o1.Name) 
        + '(' + RTRIM(o1.type) + ')' 
       COLLATE SQL_Latin1_General_CP1_CI_AS 
        AS ParentObject, 
      QUOTENAME(sch2.name) + '.' + QUOTENAME(o2.Name) 
        + '(' + RTRIM(o2.type) + ')' 
       COLLATE SQL_Latin1_General_CP1_CI_AS AS ObjectName, 
      col_name(s.depid, s.depnumber) AS 'column' 
     FROM sys.sysdepends s 

     INNER JOIN sys.all_objects o1 ON s.id = o1.object_id 
     INNER JOIN sys.schemas sch1 ON sch1.schema_id = o1.schema_id 
     INNER JOIN sys.all_objects o2 on s.DepID = o2.object_id 
     INNER JOIN sys.schemas sch2 ON sch2.schema_id = o2.schema_id 
       WHERE o1.object_id <> o2.object_id 
    ), cte AS (
     SELECT 
      0 AS lvl, 
      ParentID, 
      ObjectId, 
      ParentObject, 
      ObjectName, 
      [column], 
      CAST(ObjectID AS VARBINARY(512)) AS Sort 
     FROM obj WHERE ParentName = @ObjectName 
     UNION ALL 
     SELECT 
      p.lvl+ 1, 
      c.ParentID, 
      c.ObjectId, 
      c.ParentObject, 
      c.ObjectName, 
      c.[column], 
      CAST(p.sort + CAST(c.ObjectID AS VARBINARY(16)) 
       AS VARBINARY(512)) 
     FROM cte p 
     INNER JOIN obj c ON p.ObjectID = c.ParentID 
    ) 
     SELECT 
      ObjectName,   [column], 

      '|-' + REPLICATE('-',(lvl * 4)) + ObjectName 
     FROM cte 
     ORDER BY Sort 

結果：

|  OBJECTNAME | COLUMN |   COLUMN_2 | 
|-----------------|--------|-------------------| 
| [dbo].[test](U) |  t | |-[dbo].[test](U) | 
| [dbo].[test](U) |  t1 | |-[dbo].[test](U) | 
| [dbo].[test](U) |  t2 | |-[dbo].[test](U) | 

順便說一句，你是否知道關於sp_depends可？它做同樣的事情（提示：類型sp_helptext N'sys.sp_depends'在Query Analyzer）
