SQL如果在临时表中存在

Question

我正在查看许多帐单和应收帐款数据。 我们想知道哪些患者仍有余额。 数据包括帐单和现金收款，因此，当患者“还清”其帐户时，很多金额总计为零。 帐单数据为380万行。 我创建的临时表告诉我哪些患者的付款人仍然有余额。 我想在380万行数据上创建一列，告诉我临时表上是否存在患者和付款人，“是”或“否”-这将告诉我数据行是否仍然与现金收集目的相关，或者由于已经收集而可以忽略不计。

运行以下命令时遇到以下错误：

信息156，第15层，州1，第79行
关键字“ IF”附近的语法不正确。

Msg 102，第15级，状态1，第80行
'，'附近的语法不正确。

错误从底部大约12行的“ IF Exists”行开始。 如果难以理解，我谨此致歉； 这是我第一次问问题，我不是编写查询的经验最丰富的人，但是过去两年来我经常访问此网站，直到现在我一直在寻找我需要的东西。 我可能会烦恼，但要感谢您的事先帮助。

请让我知道您可能有什么问题。

查询中不能包含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
