在SQL中，选择一对多表中的所有FK，其中FK的表数据存在于多个列表/联接中

我的数据库中有带关联数据的配方（在一系列类别中，每个配方都有[0-多个]选项供每个类别选择）。要搜索食谱，用户可以从[0-多]类别中选择[0-多]选项

我试图构造一个存储过程，返回所有RecipeID，这些RecipeID至少与用户至少选择一个OptionID的每个类别的OptionID匹配

因此-如果您想找到所有主菜和水果甜点，proc需要返回所有RecipeID，其中：

• 在RecipeData中，对于具有相同RecipeID的所有条目（对于单个配方的所有选项）
  • 至少有一个OptionID用于“主菜”或至少有一个OptionID用于“甜点”
  • 至少有一个选项ID是“水果”
  • 并忽略“排名”（用户未在此类别中选择任何选项）

类别的数量有限（目前为12个）。现在，我将用户的搜索查询作为12个表变量提供—每个类别一个，列出该类别所选的optionID。我更愿意将用户的搜索查询作为单个表提交给proc，但我不确定这是否可行。不管怎样，这是一个较低的优先级

必须能够构造一个查询来返回我要查找的内容，但我不知道如何执行此操作。我所能想到的一切都涉及到在组中循环（每个配方的RecipeData、每个类别的选项），据我所知，SQL并不是为实现这一点而构建的

我可以在SQL中这样做，还是必须在C代码中这样做？如果我能在SQL中做到这一点-怎么做

参数：

DECLARE @MealTypeOptionID TABLE ( OptionID INT )
DECLARE @IngredientOptionID TABLE ( OptionID INT )
DECLARE @RankingOptionID TABLE ( OptionID INT )

-- all 'Main Dish' or 'Dessert' recipes that have 'Fruit'
INSERT INTO @MealTypeOptionID (OptionID) VALUES (1), (2)
INSERT INTO @IngredientOptionID (OptionID) VALUES (4)
