您是否嘗試過兩個查詢之間寫UNION？ – 2010-07-29 02:42:30

是的，我試過了，但我得到了一個錯誤 – user335160 2010-07-29 02:46:26

消息156，級別15，狀態1，行26 關鍵字'WITH'附近的語法不正確。 Msg 319，Level 15，State 1，Line 26 關鍵字'with'附近的語法不正確。如果此語句是公用表表達式或xmlnamespaces子句，則前面的語句必須以分號結尾。 – user335160 2010-07-29 02:47:08

我認爲這可能做到這一點（我還做了一點更具可讀性）：

WITH LatestJob AS (
    SELECT * FROM 
     (SELECT 
      aId 
      ,Position 
      ,StartDate 
      ,Enddate 
      ,SpecializationId 
      ,ROW_NUMBER() OVER (PARTITION BY aId ORDER BY 
       (CASE WHEN Enddate IS NULL THEN 0 ELSE 1 END) ASC 
       ,CAST(Enddate AS datetime) DESC 
      ) AS RN 
     FROM 
      EmploymentDetails ed 
     ) E 
    WHERE RN = 1 
    ) 
    ,EarliestStart AS (
     SELECT 
      aID 
      ,SUM(DATEDIFF(YEAR, Startdate, ISNULL(Enddate,GETDATE()))) AS YearsExperience 
     FROM 
      EmploymentDetails 
     GROUP BY 
      aId 
    ) 
    (
    SELECT 
     u.Id 
     ,u.FirstName + ' ' + u.LastName AS NAME 
     ,lj.Position AS LatestPosition 
     ,aps.cId 
     ,aps.ApStatusID AS ApplicationStatus 
     ,aps.sId AS SpecializationId 
     ,YearsExperience 
     ,ad.ExpectedSalary 
     ,REPLACE(ISNULL(Address1, '') + ', ' + ISNULL(Address2, '') + ', ' + ISNULL(City, ''), ', ,', ',') AS Address 
    FROM 
     Users u 
    JOIN 
     LatestJob lj ON u.Id = lj.aid 
    JOIN 
     EarliestStart ye ON ye.aId = u.Id 
    JOIN 
     ApplicantDetails ad ON ad.aId = u.Id 
    JOIN 
     ApplicationStatus aps ON aps.aId=u.Id  
    ) 
UNION ALL 
    (
    SELECT 
     u.Id 
     ,u.FirstName + ' ' + u.LastName AS NAME 
     ,lj.Position AS LatestPosition 
     ,YearsExperience 
     ,ad.ExpectedSalary 
     ,REPLACE(ISNULL(Address1, '') + ', ' + ISNULL(Address2, '') + ', ' + ISNULL(City, ''), ', ,', ',') AS Address 
    FROM 
     Users u 
    JOIN 
     LatestJob lj ON u.Id = lj.aid 
    JOIN 
     EarliestStart ye ON ye.aId = u.Id 
    JOIN 
     ApplicantDetails ad ON ad.aId = u.Id 
    WHERE 
     u.RoleId = 3 
     AND u.UserStatusId = 1 
     AND lj.SpecializationId = 38 [email protected] 
)

希望我沒有失去任何信息或沿着錯誤的複製下來辦法。它只解析正確，所以我不知道它是否會真正返回你想要的。

非常感謝你的工作 – user335160 2010-07-29 03:23:24

嘗試以下操作：

        CASE WHEN Enddate IS NULL THEN 0 ELSE 1 END ASC, 
        (CAST(Enddate as datetime)) DESC) AS RN 
     FROM EmploymentDetails ed) E WHERE RN=1 
    ) 
), EarliestStart AS (
    SELECT aID, sum(DATEDIFF(YEAR,Startdate, isnull(Enddate,getdate()))) AS YearsExperience 
    FROM EmploymentDetails GROUP BY aId 
) 

    SELECT u.Id,u.FirstName + ' ' + u.LastName AS NAME 
     , lj.Position AS LatestPosition
