sql - T-SQL 流程设计和执行计划（UDF 参数嗅探？）

Question

在 SQL Server 2005 上，我有一个复杂的多级分配过程，如下所示（伪 SQL）：

FOR EACH @LVL_NUM < @MAX_LVL:
INSERT INTO ALLOCS
SELECT 'OUT', *
FROM BALANCES(@LVL_NUM)
INNER JOIN ALLOCN_SUMRY(@LVL_NUM)

INSERT INTO ALLOCS
SELECT 'IN', *
FROM BALANCES(@LVL_NUM)
INNER JOIN ALLOCNS(@LVL_NUM)
INNER JOIN ALLOCN_SUMRY(@LVL_NUM)

WhereALLOCS以直接分配为种子，然后BALANCES(@LVL_NUM)基于ALLOCSat @LVL_NUM（可能是一些直接分配加上前一级别的一些 IN 分配），并且ALOCNS(@LVL_NUM)基于BALANCES(@LVL_NUM)并且ALOCN_SUMRY(@LVL_NUM)仅基于ALOCNS(@LVL_NUM)- 有很多配置表，这些配置表指示驱动程序将分配赶出去。

这被简化了，但实际上循环中有四五对这样的对，因为有多种逻辑无法一起处理（有些情况可以一起处理）。

其基本逻辑是在特定成本中心/产品线/等（即）中获取总金额，然后根据其在特定成本中心/产品线/等中的份额（即百分比份额）将BALANCES其分配给另一个成本中心/产品线/等。ALLOCNS / ALLOCN_SUMRY公制。

在记录OUT保存IN和SUMRY.ALLOCN是一个加号！）。（现有的系统是一个怪物 C/C++/MFC/ODBC 程序，它将所有数据读入海量数组和其他数据结构中，编写得非常糟糕。）

问题似乎是，当在循环中运行时，我似乎遇到了执行计划问题，因为随着ALLOCS表格开始发生变化（并且一切都在变化，因为级别有不同的成本中心，所以配置被用来驱动ALLOCNS正在改变）。我认为我最多有 99 个级别，但最低级别从 2、4、6 开始。似乎@LVL_NUM = 6在 UDF 之外单独运行表现良好，但 UDF 表现不佳 - 可能是因为 UDF 有缓存计划或整体计划已经很糟糕了，因为在ALLOCS前面的步骤中添加了@LVL_NUM IN (2, 4)。

在开发早期，我设法在 30 分钟内完成了 30 个关卡，但现在我无法在 2 小时内完成前 3 个关卡。

我正在考虑在另一个 SP 中运行这两个插入并将其称为 WITH RECOMPILE，但很好奇这个 RECOMPILE 是否正确级联到 TVF UDF？任何其他建议也将不胜感激。

Answer 1

是的，重新编译应该扩展到 TV UDFS。

但是，我会使用参数掩码而不是 RECOMPILE。

1. 使用这样的查询，编译会很昂贵
2. 当 UDF 未嵌套时，参数掩码也将应用。TV UDF 没有这样的计划：它们是调用查询的一部分，因为它们是非嵌套的。

您可以将一些 UDF 调用分解为临时表，然后加入临时表吗？我敢打赌，当 UDF 未嵌套时，查询太复杂而无法有效运行。优化者可能需要一周的时间才能找到包含如此复杂事物的理想计划。使用临时表（不是表变量），我想你会得到可观的改进。

我自己在一些更大的查询中使用了这种技术（为金融工具生成定价树）

你 150,000 行的事实被我认为的绝对复杂性所掩盖。

编辑：

TVF 不需要参数屏蔽，因为它们只是宏。您可以从字面上用 CTE 或派生表替换它。

Answer 2

使用表值函数（尤其是多语句表值函数）要注意的一件事是生成的表，就像表变量一样，没有列统计信息和索引。

我倾向于谨慎使用 TVF。

Answer 3

你能发布实际的 T-SQL 而不是伪 SQL 吗？您所描述的听起来像是随着@LVL_NUM 的增加而对越来越大的结果集进行表扫描，并且可能 RECOMPILE 在那里无济于事。但是，基于伪SQL，除了伪猜测之外真的很难给出任何东西......
