在SQL Server 2005上，我有一个复杂的多级分配过程，看起来像这样（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)
ALLOCS通过直接分配播种，然后BALANCES(@LVL_NUM)基于ALLOCS @LVL_NUM（可能是某些直接分配加上之前的一些IN分配）级别）ALOCNS(@LVL_NUM)基于BALANCES(@LVL_NUM)而ALOCN_SUMRY(@LVL_NUM)基于ALOCNS(@LVL_NUM) - 有很多配置表，指示驱动分配的驱动程序。
这是简化的，但在循环中实际上有四到五对这样的对，因为有多种逻辑不可能一起处理（以及一些可以一起处理的情况。）
基本逻辑是在特定成本中心/产品线/等（即BALANCES）中获取总金额，然后根据其份额将其分配到另一个成本中心/产品线/等（即特定指标的ALLOCNS / ALLOCN_SUMRY百分比份额。
在OUT记录和IN，以及基于SUMRY详细信息的ALLOCN中重复了这么多逻辑，我最终使用内联表实现了值函数，它们表现得相当好（并且它们与回归测试中现有系统的行为相匹配，这是一个加分！）。 （现有系统是一个怪物C / C ++ / MFC / ODBC程序，它将所有数据读入大量数组和其他数据结构，并且写得非常糟糕。）
问题似乎是当在循环中运行时，我似乎正在获得执行计划问题，因为随着ALLOCS表开始改变而逐渐上升（并且一切都在变化，因为级别具有不同的成本中心，因此用于驱动ALLOCNS的配置正在发生变化。我认为我有多达99个级别，但是最低级别从2,4,6开始。看起来在UDF之外单独运行@LVL_NUM = 6表现不错，但是UDF表现不佳 - 大概是因为UDF有一个缓存的计划，或者由于ALLOCS之前的步骤中添加了@LVL_NUM IN (2, 4)，整体计划已经很糟糕。
早期开发中，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命名为WITH RECOMPILE，但是如果这个RECOMPILE正确地级联到TVF UDF中，我很好奇吗？任何其他建议也将不胜感激。

是的，重新编译应该扩展到TV UDFS。
但是，我使用参数掩码而不是RECOMPILE。
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被取消时，查询太复杂而无法有效运行。优化者可能需要一周时间才能找到理想的计划，其中包含如此复杂的内容。使用临时表（不是表变量），我猜你会得到可观的改进。
我自己在一些较大的查询中使用了这种技术（为金融工具生成定价树）
我认为，150,000行的事实被我认为的复杂性所掩盖。
修改：
TVF不需要参数屏蔽，因为它们只是宏。你可以用CTE或派生表替换它。

表值函数（尤其是多语句表值函数）需要注意的一点是，结果表就像表变量一样，没有列统计信息，也没有索引。
我倾向于谨慎使用TVF。

你能发布实际的T-SQL而不是伪SQL吗？ 您所描述的内容听起来像表格扫描越来越大的结果集，因为@LVL_NUM增加，可能RECOMPILE将无助于此。但是，基于伪SQL，除了伪猜测之外真的很难给出任何东西......
