我需要在我的巨大查询中添加另外几个左外连接。这对我来说变得越来越困难，因为查询太大了，我现在无法处理。我想知道是否有某种方法可以将查询自动转换为维恩图。

是否有工具可以进行查询并绘制代表查询的文图？

我正在寻找 sql server、c# 或 python 中的解决方案？

是否有一种自动化的方式来以图形方式表示查询？

一次可以根据查询构建 CTE：

DECLARE @start_date AS DATETIME = '2012-02-02'; 
WITH L0 AS (SELECT 1 AS C UNION ALL SELECT 1),       --      2 
     L1 AS (SELECT L0.C FROM L0 CROSS JOIN L0 AS B), --      4 
     L2 AS (SELECT L1.C FROM L1 CROSS JOIN L1 AS B), --     16 
     L3 AS (SELECT L2.C FROM L2 CROSS JOIN L2 AS B), --    256 
     L4 AS (SELECT L3.C FROM L3 CROSS JOIN L3 AS B), --  65536 
      N AS (SELECT ROW_NUMBER() OVER(ORDER BY L4.C) AS n FROM L4), 
      D AS (SELECT DATEADD(SECOND, n - 1, @start_date) AS d, n FROM N) 
SELECT d from D where n <= (60 * 60 * 24)

请注意，最终SELECT可以使用任何或所有 CTE 中间结果。这可以大大简化开发和测试。

编辑：在你的情况下是这样的。

WITH 
  MLIS as ( -- Description of what this piece is supposed to mean.
    SELECT DISTINCT mlis_practice_id, requestor_npi, requestor_first_name, requestor_last_name  
      FROM complete  
      WHERE Len(requestor_last_name) > 0 ),
  Physician as ( -- Description of what this piece is supposed to mean.
    SELECT *
      FROM millennium_dw..d_physician  
      WHERE received_ims_information = 1 ),
  Client as ( -- Description of what this piece is supposed to mean.
    SELECT *  
      FROM millennium_dw..d_client  
      WHERE rec_active_flg = 1 ), 
  cte_biggie as ( -- Something I've totally bodged that should use the above CTEs.
    SELECT LEFT('I'+Replicate(' ', 2), 2), ... )
SELECT * from CTE_Biggie
