我希望优化一个需要花费大量时间才能运行的查询（大约1.5小时），并且通过查看执行计划，其中一个最大的漏洞似乎是将主查询中的数据插入到临时表。当我将数据插入临时表时，有以下过程：
流程（成本％）
Compute Scalar (0%) <-- Stream Aggregate (0%) <-- Sort(0%) <-- Table Spool (eager spool) (10%)
哪个有道理，但对我来说什么不是这个出现了9次？
我可以包含查询/索引信息，如果这会有所帮助，但查询本身很长，我不想把这个问题写成一篇文章！
谢谢， 达文。
编辑以包含查询 - 抱歉长度！

同时提出一个小建议，您可能会发现在将数据插入临时表之后最好在临时表上创建索引，因为这样做可以提高插入速度。事先创建它意味着必须为插入临时表的每个记录修改索引。
答案 1 :(得分：1)
我会调查使用交叉表查询（PIVOT command in Sql Server）重写您的查询。这就像GROUP BY语句，除了它将聚合值放入列而不是行，这就是你正在做的事情。可能需要一点时间才能完成它，但是努力是值得的，你将不会拥有所有复制粘贴代码，并且它应该运行得更快。

附加表： - 数据在这里并不重要，但是这些链接到#donation表以确定捐赠是否是紧急捐赠（#gift表中的所有内容都被认为不是紧急情况）< / p>
CREATE TABLE #FUND
(
donation_id NVARCHAR(255)
,fund_id NVARCHAR(255)
,finance_code NVARCHAR(10)
,finance_code2 NVARCHAR(10)
)
CREATE TABLE #audit
(
entity_name NVARCHAR(255)
,changes NVARCHAR(5000)
)
创建表#donation_fund （donation_id NVARCHAR（255） ，fund_id NVARCHAR（255） ）
#fund表用于确定#donation表中的捐款是否是紧急情况 - 基金ID是否为紧急资金是由#audit表中的数据决定的。
要确定#donation是否是紧急情况，请使用以下脚本：
CASE WHEN #donation_fund.fund_id IN --all emergency funds
(
select f.id
FROM _audit a
INNER JOIN _fund f ON a.article_id = f.id
WHERE a.entity_name = 'Fund'
AND a.Changes LIKE
'%finance_code2%OldValue>3%'
UNION
select
id
FROM _fund
WHERE (finance_code2 LIKE '3%'
OR finance_code2 LIKE '9%')
AND finance_code2 IS NOT NULL
) THEN 'Emergency' else 'Non-emergency' end as type2
