從字符串轉換爲uniqueidentifier時轉換失敗sql server 2014

這是我的SQL查詢。執行此查詢時，我得到以上錯誤從字符串轉換爲uniqueidentifier時轉換失敗sql server 2014

WITH Results_CTE AS (select Top 20 ROW_NUMBER() OVER (ORDER BY KeyId desc) AS SNo,* from(select * from ( select ps.Id as KeyId,dps.Id as SettingId,dps.DocumentType,dps.DocumentProcessingType,null as Description,null as Link 
      from [ParttimerSalary] ps inner join [ParttimerEmployee] pe on pe.Id = ps.ParttimerEmployeeId 
      inner Join [DocumentProcessingSetting] dps on dps.Step = ps.Step and dps.KeyId = pe.ParttimerType and 
      (dps.RoleId = 'e218e9e0-d51d-45b4-9380-77f43ac50f0d' or dps.UserId = '1967681a-7d64-486e-99a8-4b58746cef81') and dps.DocumentType = 2 union all 
      Select 'Incident/service is assigned for you' as [Description],'#/it/incidentsupport/' as Link,0 as Id,0 as SettingId,0 as DocumentType,0 as DocumentProcessingType from Incident where IncidentStatus = 2 and SupportById = '1967681a-7d64-486e-99a8-4b58746cef81' 
      )wrapped) listing ORDER BY KeyId desc) SELECT * FROM Results_CTE WHERE SNo >= 0 AND SNo <=20

任何幫助，將不勝感激。謝謝

在使用Union時，所有數據類型都應該在選擇元素中匹配。

ps.Id由於KeyId是唯一標識符，而'事件/服務爲您指定'，因爲[Description]是錯誤原因的字符串。

其實，我已經改變了工會的關鍵字後，從表中選擇列，如工會期間的訂單，我們需要管理秩序，數據類型等的兩個表的領域和問題得到解決。無論如何謝謝
