调整存储过程以实现超过 300,000 条记录的高性能答案

【问题标题】：Tweaking Stored Procedure for High Performance across 300,000+ records调整存储过程以实现超过 300,000 条记录的高性能
【发布时间】：2016-02-13 01:52:12
【问题描述】：

我正在尝试构建一个用于 jQuery DataTables 前端 API 的 T-SQL 存储过程。前端 UI 为调用过程提供 orderby、过滤器、显示起始行和显示长度，如下所示。

为了提高性能，我在以下查询中是否遗漏了什么？

我需要向最终用户显示所有列，但我只需要 @NumberOfRowsToTake 参数中提供的行。

感谢您的宝贵时间。

【问题讨论】：

动态order by 子句可能会导致一些意外结果（即缓存错误的查询计划）。你有什么确切的问题？我已经看到with recompile 确实有帮助，尽管并不理想。也许使用动态 sql 构建查询会更快——很难说。像往常一样，它只是取决于性能。
@speddes 我在 Web UI 前端有一个表，它需要显示来自相当大的数据库表的记录。我一次只需要显示一组记录；但我需要指定的所有列。理想情况下，人们可以对文本列进行部分搜索，动态排序（排序），然后对结果进行分页。

【解决方案1】：

SP 永远不会像现在这样快；你要重写了。你可以用它做的唯一一件简单的事情就是尝试 WITH RECOMPILE/OPTION (RECOMPILE)，这看起来像是一个讨厌的编译。

考虑阅读Erland Sommarskog's article Dynamic Search Conditions in T‑SQL，它详细讨论了这种一般情况。

老实说，按照您的结构方式，您可能应该查看sp_executesql 并将每个变量都作为参数传递给 sp_executesql。

这样，您至少会为每个参数组合获得一个专用的查询计划，并且不会有多余的废话。

在构建动态 SQL 语句时，仅使用您需要的 WHERE 和 ORDER BY 部分，但 不要连接直接传递给 SQL 本身的值（这将允许恶意用户进行 SQL 注入） ;将它们用作参数，或作为放入 SQL 块的 IF 语句的一部分。

然后摆脱你的非 SARGable JOIN 和 WHERE 部分，就像那些 CHARINDEX()s - 在 WHERE 或 JOIN（或者甚至 ORDER BY，如果可能的话）子句中没有功能，请，然后您的索引就可以完成它们的工作了！

对于您的@StartingRow 和@NumRowsToTake 分页，请考虑升级到SQL Server 2012 或更高版本并阅读Aaron Bertrand 的Pagination with Offset Fetch；他在其中的一些选项上有一些很好的基准和指标。请注意，您甚至应该阅读 SQL Server 2008 的前几段，尤其是

根据表的索引、所需的列和选择的排序方法，分页可以相对轻松。如果您正在寻找“前”20 个客户并且聚集索引支持该排序（例如，IDENTITY 列或 DateCreated 列上的聚集索引），那么查询将非常有效。如果您需要支持需要非聚集索引的排序，特别是如果您有输出所需的列未被索引覆盖（如果没有支持索引，请不要介意），查询可能会变得更加昂贵。即使是相同的查询（使用不同的@PageNumber 参数）也会随着@PageNumber 的增大而变得更加昂贵——因为可能需要更多的读取来获取数据的“切片”。

【讨论】：

快速说明——这篇文章是给SQL Server 2008的。使用 fetch and offset 是 2012 年引入的...除此之外，同意您的大多数 cmets。
我还没有读过 Sommarskog 发表的那篇文章——+1，非常好的深度阅读。非常有用的 imo。
@Anti-weakpasswords 感谢您的 cmets；根据您所写的内容，我基本上应该构建动态 SQL，然后执行它？另外，我应该使用 LIKE 而不是 CHARINDEX？如果可能，我想支持部分字符串搜索。如果这会严重影响性能，那么我可以放弃它。
尝试添加一个 recompile 选项 - 这会有所帮助。此外，所有这些案例都在计算 ROW_NUMBER - 为什么要在 ORDER BY 子句中重复案例列表？按 row_number 结果排序。
@ChrisK。 - 如果您想甚至考虑索引，只要通配符不在左侧，您就可以使用 LIKE；如果最左边的字符是通配符，则不能使用索引。另外，我强烈建议至少需要几个字符，因为 LIKE 'M%' 并没有真正的用处，尽管 LIKE 'MICH%' 可能有机会获得合理的结果。
