插入前的表线轴？
Posted
技术标签:
【中文标题】插入前的表线轴？【英文标题】：Table Spool right before insert? 【发布时间】：2017-03-10 02:38:07 【问题描述】：我对 SPOOL 的理解是将数据存储到临时表中，以便 SQL Server 在有 CTE 或其他用途时可以使用它。这是否意味着 SPOOL 应该出现在我的执行计划中间？
使用下面的查询（我将 SELECT * 放在这里以使查询更小），SPOOL 显示在我的执行计划中的 INSERT 和 CONCATENATION 操作之间。只是想知道这个 SPOOL 有什么作用？因为它在我的执行计划中花费了大约 30%。想知道我是否可以让计划摆脱它。编辑：Execution Plan uploaded

【问题讨论】：
可以在这里分享执行计划吗 Spool 不一定意味着坏事，即使是 30%。你没有提到实际问题，比如它是慢还是非常慢等等。很抱歉这么说，但你的查询很很长，有很多计算。想知道当“这些表填充”或您的数据库设计时您在做什么。 @KumarHarsh，明白 SPOOL 不一定是坏事。只是想知道为什么它会出现在 INSERT 和 UNION 之间。可以理解 SPOOL 是否在 UNION 进程之前显示，因为这一切都有很多 JOIN。但是后面就只是INSERT，不明白SQL Server为什么会在这里放一个SPOOL。是的，有很多计算，这就是用户想要的。仍在调整查询。 @TheGameiswar，当然。但需要其他人帮助从服务器下载生成的计划。拿到文件后会上传到这里。 @KumarHarsh，我之所以调查这个问题是因为这个查询大约需要 1 小时才能完成（TBL2、3、5 都有大约 1300 万条记录）。 INSERT 约为 70%，SPOOL 约为 25%。所以如果没有必要，我想把这个 SPOOL 拿出来。 【参考方案1】：Soool 是 temp db 中数据的副本。
查询已使用 cte 来创建新的 cte，因此执行逻辑变得复杂以解决 sql server 需要创建临时结果集的问题，这在查询计划中与假脱机一样可见。

【讨论】：
明白这一点。但是它不应该出现在 UNION 之前的某个地方吗？因为那里有我做所有 JOIN 和计算的地方。为什么会在结果JOINed后出现？ 您可以共享执行计划 .... 如前所述，它可能是 sql server 需要进一步存储一些临时数据的任何地方，并且在 union sql server 中需要删除重复的数据它需要缩短数据并比较结果集.. ... @桑迪普·拉瓦特。刚刚上传了执行计划。【参考方案2】：恕我直言，在 CTE 中没有过滤或计算的地方 例如LK_ALL，你可以直接使用#DBNAME#.DBO.#TBL4# where req.它可能会或可能不会提高性能，但至少会减少行数。
调试整个查询真的很难。
但是看这里而不是这么多左连接（顺便说一句，如果你可以使用内连接） 你可以像这样重写你的查询，
FROM STEP2
Inner/LEFT JOIN LK_ALL D1 ON (STEP2.G_BANKNO = D1.CD AND D1.FIELDNAME = 'G_BANKNO')
or (D2.FIELDNAME = 'G_CSTCTR' AND STEP2.G_CSTCTR = D2.CD )
or (D3.FIELDNAME = 'G_GLACCTNO' AND STEP2.G_GLACCTNO = D3.CD )
or (D4.FIELDNAME = 'G_GLACCTYP' AND STEP2.G_GLACCTYP = D4.CD )
or (D5.FIELDNAME = 'G_GLACCTINT' AND STEP2.G_GLACCTINT = D5.CD )
or (D6.FIELDNAME = 'T_RTTYP' AND STEP2.T_RTTYP = D6.CD )
or (D7.FIELDNAME = 'T_PMTTYP' AND STEP2.T_PMTTYP = D7.CD )
or (D8.FIELDNAME = 'T_NIDPMMD' AND STEP2.T_NIDPMMD = D8.CD )
or (D9.FIELDNAME = 'T_CAHSSS' AND STEP2.T_CAHSSS = D9.CD )
or ( D10.FIELDNAME = 'R_LOBCD' AND STEP2.R_LOBCD = D10.CD )
or ( D11.FIELDNAME = 'R_BRNCHCD' AND STEP2.R_BRNCHCD = D11.CD )
or ( D12.FIELDNAME = 'R_PRODCD' AND STEP2.R_PRODCD = D12.CD )
or ( D13.FIELDNAME = 'R_TYPCD' AND STEP2.R_TYPCD = D13.CD )
or ( D14.FIELDNAME = 'R_HPTYPCD' AND STEP2.R_HPTYPCD = D14.CD )
我希望那些硬编码的参数在现实生活中是动态的 你也可以这样做，
声明@From date= dateadd(day,-1,'2016-10-01')
声明@To int= DAY(DATEADD(D, 1, CONVERT(DATE, RP_DATA_DT)))
对于数百万条记录，临时表优于 CTE。
您还可以评论部分查询以查看性能。
【讨论】：
@ KumarHarsh 感谢您的建议。将尝试使用 Temp Table 代替 CTE 来查看是否可以加快查询速度。是的，所有这些硬编码的日期和字符串确实是可变的。生成时只输出固定值。 不，CTE 一般不存储在内存中。由执行计划决定是否应该将部分数据存储在 spool 中。以上是关于插入前的表线轴？的主要内容，如果未能解决你的问题，请参考以下文章
