我正在使用以下代码尝试UNION两组数据，虽然它运行没有错误，它运行超过10分钟并且没有返回结果所以我想知道我是否做错了什么？
select BIH.SourceCode, BIH.MarketValueAmt as CorrectedAmt
from [dbo].[IRA_HIST] as BIH
JOIN
(select accountno, accountclass
from accounttable
where accountclass in ('A','B','C','D')) AS AccountNos
ON BIH.ACCOUNTNO = ACCOUNTNOS.ACCOUNTNO
where BIH.securityno > '0'
UNION
SELECT SourceCode, (Amount*(-1)) as CorrectedAmt
from accttable a, activitytable b
where a.accountclass in ('A','B','C','D')
and b.recordtype in ('r','c')
任何指导都非常有用。

由于来自accounttable的数据不需要其他计算和转换，您可以直接将其与ira_hist连接，无需进行子查询。此外，您需要将此设置为ON。[键列] = b。[键列] - 您的第二个查询中的加入可能是accountno

在您的第二个 SELECT 中，由于您要查询同一个表两次，因此您应该能够加入公共密钥（例如FROM TABLE a JOIN TABLE b ON a.cKey = b.cKey）。
或者，您可以简化第二个 SELECT ：
FROM TABLE WHERE AccountClass IN ('A', 'B',...) OR RecordType IN ('r', 'c')
