SQL -Update Table2與來自Table1的數據，但不更新表2中的確切重複

Question

[涉及2個表格]我需要從TABLE1獲取跟蹤編號並將該值賦予TABLE2中的跟蹤編號列，即匹配記錄。雖然，我只需要爲TABLE2中不重複的記錄執行此操作。這意味着TABLE2中的第2行和第3行不需要更新（因爲它們完全相同），但只有第1行和第4行必須更新。我如何獲得？
還有其他欄目，但我沒有包括它們來讓示例更清晰。您在下面的查詢中看到的其他字段是使記錄具有唯一性的字段。首先，我不確定我寫的查詢是否是正確的，因爲我在解決這個問題時遇到了問題。其次，選擇工作，它是選擇，所有的值表示匹配的查詢號碼，但是當我有更新我得到一個錯誤：

(「Msg 116, Level 16, State 1, Line 24 Only one expression can be specified in the select list when the subquery is not introduced with EXISTS」).

我真的很感激一些幫助，感謝

TABLE1

|Pro #| Dept|Amount |Tracking # | 
|-----|-----|--------|-----------| 
|___2 | _35 |______5 | ______32 | 
|___2 | _35 |_____10 | ______35 | 
|___2 | _35 |_____10 | ______12 | 
|___2 | _35 |______8 | ______23 | 

TABLE2

|Pro #| Dept | Amount |Tracking # | 
|-----|-------|--------|-----------| 
|___2 | _35 | ______5| YES, it needs tracking # 
|___2 | _35 | _____10| NO, does not need tracking # 
|___2 | _35 | _____10| NO, does not need tracking # 
|___2 | _35 | ______8| YES, it needs tracking #

你需要的東西是這樣的：

UPDATE t2 
SET [TrackingNumber] = t1.[TrackingNumber] 
FROM [TABLE2] t2 
INNER JOIN 
    (SELECT ProNum, 
     Dept, 
     AllocAmt, 
     Count(*) AS CNT 
    FROM [TABLE2] 
    GROUP BY ProNum, 
      Dept, 
      AllocAmt 
    HAVING count(*)<2 
) a 
ON t2.AllocAmt =a.AllocAmt AND 
    t2.ProNum = a.ProNum AND 
    t2.dept = a.dept 
INNER JOIN [TABLE1] t1 
ON t2.[Source] = t1.[Source] AND 
t2.[Yr] = t1.[Yr] AND 
t2.[Season] = t1.[Season] AND 
t2.[Per] = t1.[Per] AND 
t2.[Wk] = t1.[Wk] AND 
t2.[Div] = t1.[Div] AND 
t2.[Dept] = t1.[Dept] AND 
t2.[Vend] = t1.[Vend] AND 
t2.[KeyRec] = t1.[KeyRec] AND 
t2.[RTV] = t1.[RTV] AND 
t2.[AllocAmt] = t1.[AllocAmt] AND 
t2.[ProNum] = t1.[ProNum] AND 
a.[Dept] = t1.[Dept] AND 
a.[AllocAmt] = t1.[AllocAmt] AND 
a.[ProNum] = t1.[ProNum]
