具有分页、性能和优化的动态 SQL 查询

Jam*_*gan 2 performance sql-server dynamic-sql azure-sql-database query-performance

我面前有一个有趣的问题。有一个数据库有大约 100 万个用户帐户，预计每年增长 1-200 万个。该数据库是强 TPT，但此特定查询和所涉及的表不涉及任何 TPT 内容。

当指定第二个数据点（即电子邮件地址和姓氏、公司等）时，sproc 和视图的当前设计需要大约 15 秒来执行 (x2)。该数据库是 SQL Azure P11，但它不是 DTU 绑定查询，升级到最高可用产品 (P15) 对结果没有影响。

下面是 sproc、视图和执行计划。在过去 24 小时内重建或重组了所有索引，并更新了所有统计信息。例如，在查看数据时，历史电子邮件地址 (1..N) 的概念目前正在使用 aCROSS APPLY来获取最新的，这可以防止索引视图，可以通过简单地连接历史电子邮件地址和持久化来解决它们在一个列中。

许多数据库在 nvarchar(4000-max) 列中使用 JSON，所有这些列都有一个公开值并启用索引的计算列。范式必须支持分页，我正在寻找有关如何优化它的反馈/建议。

在这一点上，更改表结构不是一个可行的选择，尽管我可以通过一点点操作看到前进的道路。有没有人对我应该首先看哪里有任何想法？我已经对未知的重新编译和优化进行了测试，以查看是否有任何影响，如果有，则可以忽略不计。

注意：一些业务逻辑（专有列名被删除或修改，sproc和view不能按原样执行，但在功能上与源相同。

两个简单的改进：

通过强制转换@CompanyPublicIdValue为与UserPublicId相同的类型来修复此查询。 @CompanyPublicIdValue是 an nvarchar(32)，它的数据类型优先级高于列类型。所以比较需要对每一行进行转换。

它很贵，不应该。
```
SET @CompanyUserIdValue =
    (
        SELECT UserId
        FROM Application.Users
        WHERE UserPublicId = @CompanyPublicIdValue
    )
```

不是在一个查询中计算行数并在下一个查询中返回它们，而是将键值提取到第一个查询中的临时表/表变量中，并将其加入到第二个查询中。

然后努力改进标识要返回的键的查询。也许该查询可以直接访问基表或索引视图。然后最终查询将您现有的视图连接到键值的临时表。
