SQL Server 2008 R2 中的超前/滞后实现：超出最大内存

mpa*_*pag 7 performance sql-server sql-server-2008-r2 window-functions query-performance

背景

我正在尝试建立一个“访问”序列，其中如果在基本相同的地方（General_Location）检测到动物，则算作一次访问，但如果它去其他地方然后返回，则是对同一位置的额外访问。因此，如果在一个Location序列
A1, A2, A3, A3, A3, A1, B2, D4, A2
中检测到动物，例如所有 A(n) 位置都属于General_Location“A”，则前 6 个检测为访问 1 (@A)，接下来为访问 2 (@B)，接下来为访问 3 (@D)，接下来是访问 4（返回 @A）。

由于LAG并且LEAD在 SQL Server 2008R2 中不可用（也不UNBOUNDED PRECEDING在PARTITIONing 子句中），我正在尝试解决此SQL 权威博客条目中所述的变通方法。

我遇到了以下内存问题（更不用说计算时间了）：

    SELECT
        RANK() OVER (PARTITION BY det.Technology, det.XmitID ORDER BY DetectDate ASC, ReceiverID ASC) as DetID,

正如各种用户（@MartinSmith、@Frisbee）所提到或暗示的那样， 的使用AnimalID不是 的完整主键Tagged_Animal，也不是在 UNIQUE 约束中定义的。但是，表中的行数A.AnimalID=B.AnimalID AND A.TagSN<B.TagSN（当前）为零。为了使这个查询健壮，我必须强制它是唯一的（或者只是从 PK 中删除 TagSN）。

表和索引定义

##ttOrder_det（临时表）

当前在填充表之前创建索引；我正在接受测试，在填充临时表后将NONCLUSTERED非UNIQUE索引创建转移到一个位置。

收到的特定错误

  1. 无法为数据库 'tempdb' 中的对象 'dbo.SORT 临时运行存储：140737631617024' 分配空间，因为 'PRIMARY' 文件组已满。通过删除不需要的文件、删除文件组中的对象、向文件组添加其他文件或为文件组中的现有文件设置自动增长来创建磁盘空间。

  2. 数据库 'tempdb' 的事务日志已满。要找出无法重用日志中的空间的原因，请参阅 sys.databases (tempdb ACTIVE_TRANSACTION) 中的 log_reuse_wait_desc 列

  3. 执行批处理时发生错误。错误消息是：抛出了“System.OutOfMemoryException”类型的异常——（如果s在大约 3300 万条记录后直接选择）。

（估计）执行计划初始代码摘要

INSERT成本 0%
SEQUENCE成本 0% 但从 9 个不同的子步骤中提取。这些子步骤（具有典型成本）是Index Insert(2%)，然后是Sort(8%)，然后是Table Spool(2%)。NIX_A成本为 9% Index Insert，既没有NIX_TCD也NIX_F没有Sort步骤；该Table Spool对NIX_F是免费的。
该Clustered Index Insert成本为10％。
还有Sort2% 的Parallelism成本和 1% 的流分配成本。
对于SEQUENCE成本，它似乎增加了 95%，其他步骤的成本为 13%，因此显然某处存在一些舍入“错误”，可能主要在Index Insert- Sort-Table Spool序列的 14% 中。

我的问题

  1. 有什么改进的建议吗？

  2. 当我加入的副本时，我也可以分区s吗？

  3. 如果我制作s一个谨慎的临时表并适当地索引它，事情会有所改善吗？

  4. 执行所有插入后UNIQUE，在临时表中创建非索引会更有效吗？我假设（因此）索引必须预先创建以防止违反关键约束。UNIQUEPRIMARY KEY

回答我自己的问题之一

  1. 是的，是的，它会。进一步优化后
    • 用数据填充临时表需要 21 分钟
    • 1 分钟索引

这个过程之前至少持续了 1.5 小时，出现错误并且没有生成结果表。在我开始摆弄查询逻辑之前，实际上需要 4 个多小时才能出错。

当前状态

请参阅我发布的解决方案/答案。

mpa*_*pag 5

我将此作为答案提交，因为我目前正在避免内存不足类型的错误，并显着减少了运行时间（4 个多小时，以失败告终；现在是 1.25 小时，以成功告终）。但是，我确信在再增加大约 1000 万条记录后，此问题可能会再次发生，因此我希望您能提供任何旨在提高内存效率的其他评论或答案，以备将来使用。

对此的“解决方案”是从临时表的设计中删除不需要的字段，尤其是索引。此外，非约束键的索引创建被推迟到表被填满之后。

为了解决分区与后者不匹配的问题（首先由@MartinSmith 指出）JOIN，我在子查询中创建了一个字段，然后将其用于PARTITIONing 和 for JOINing。

快速评论

我改用ROW_NUMBER而不是RANK. 这是不确定的，但至少不会导致“联系”，这将导致在LAG该点附近破坏实现。联系不应该存在，但这只是针对General_Location非常接近的 s 共同检测相同传输的未来证明。

同样，正如两位用户在上面的评论中指出的那样，我没有使用Tagged_Animal表的完整 PK ，因此有可能存在JOIN不明确的AnimalID. 然而，目前，AnimalID和TagSN都是UNIQUE，尽管不受约束。

我计划放弃该ReceiverID领域以支持使用Location，但我有一段时间在同一位置部署了两个接收器（一个接收器被假定丢失但后来找到了）确实同时检测到了同一只动物
