SQL如果在臨時表中存在

Question

我正在查看許多帳單和應收帳款數據。 我們想知道哪些患者仍有余額。 數據包括帳單和現金收款，因此，當患者“還清”其帳戶時，很多金額總計為零。 帳單數據為380萬行。 我創建的臨時表告訴我哪些患者的付款人仍然有余額。 我想在380萬行數據上創建一列，告訴我臨時表上是否存在患者和付款人，“是”或“否”-這將告訴我數據行是否仍然與現金收集目的相關，或者由於已經收集而可以忽略不計。

運行以下命令時遇到以下錯誤：

信息156，第15層，州1，第79行
關鍵字“ IF”附近的語法不正確。

Msg 102，第15級，狀態1，第80行
'，'附近的語法不正確。

錯誤從底部大約12行的“ IF Exists”行開始。 如果難以理解，我謹此致歉； 這是我第一次問問題，我不是編寫查詢的經驗最豐富的人，但是過去兩年來我經常訪問此網站，直到現在我一直在尋找我需要的東西。 我可能會煩惱，但要感謝您的事先幫助。

請讓我知道您可能有什么問題。

查詢中不能包含IF改用CASE ：

, CASE WHEN EXISTS (SELECT *
                    FROM   #TempSummary b 
                    WHERE  b.concat(client.LastName,             
                                 '-',VIEW_AR_AGING.patientid,'-',VIEW_AR_AGING.payerid) 
                          =  concat(client.LastName, 
                                 '-',VIEW_AR_AGING.patientid,'-',VIEW_AR_AGING.payerid))
THEN 'yes'
ELSE 'no' END  AS Has_Balance
