       NULL                          AS [Status], 
       [pleaserateyour_x00]          AS [Overall Satisfaction], 
       [easeofuse]                   AS [Ease of Engaging], 
       responsiveness                AS Professionalism, 
       [qualityofthedeliverable]     AS [Quality of Document], 
       NULL                          AS BulkUploadReason, 
       NULL                          AS [Requested FY], 
       NULL                          AS [Requested FM], 
       NULL                          AS Vertical, 
       NULL                          AS Industry, 
       NULL                          AS PrimaryContact, 
       NULL                          AS [Topic for Proposal] 
FROM   [rfx_survey] 

Answer 1

我的回答仅适用于您插入此数据的表格，其中所有列的默认值均为NULL或＆＃39;是＆＃39;所有其他值都直接从第二个表中获取。

然后你可以使用：

INSERT INTO [allassetsurveyreport]  
     ([Overall Satisfaction], 
      [Ease of Engaging],
      Professionalism, 
      [Quality of Document])
SELECT [pleaserateyour_x00]          AS [Overall Satisfaction], 
       [easeofuse]                   AS [Ease of Engaging], 
       responsiveness                AS Professionalism, 
       [qualityofthedeliverable]     AS [Quality of Document]
FROM [rfx_survey] 

如果您按正确的顺序选择列，我不确定是否需要AS。
