SQL Server：左联接选择语句收到错误“查询处理器在查询优化期间耗尽了堆栈空间”

Question

我正在尝试创建一个包含2000多个列的View表，并且select语句中声明的属性的95％也是select语句子查询。

这是我正在尝试做的：表A = 100列的主表表C = 10列的子表

表C将联接表A。但不是A的100列+ C的10列，而是A +的100列（表中的每行10 * fk = pk，最大为200）从C。

这是我的示例代码：

select
A.*
, 

(select C.property where C.propertyNumber = 1 and C.propertyFk = A.propertyIdPk) as property1,
(select C.property where C.propertyNumber = 2 and C.propertyFk = A.propertyIdPk) as property2,
(select C.property where C.propertyNumber = 3 and C.propertyFk = A.propertyIdPk) as property3,
(select C.property where C.propertyNumber = 4 and C.propertyFk = A.propertyIdPk) as property4,
(select C.property where C.propertyNumber = 5 and C.propertyFk = A.propertyIdPk) as property5,
(select C.property where C.propertyNumber = 6 and C.propertyFk = A.propertyIdPk) as property6,
(select C.property where C.propertyNumber = 7 and C.propertyFk = A.propertyIdPk) as property7,
(select C.property where C.propertyNumber = 8 and C.propertyFk = A.propertyIdPk) as property8,
(select C.property where C.propertyNumber = 9 and C.propertyFk = A.propertyIdPk) as property9,
(select C.property where C.propertyNumber = 10 and C.propertyFk = A.propertyIdPk) as property10

from [schema].table A
left join [schema].table C on A.propertyIdPk = C.propertyFk
where C.propertyFk = A.propertyIdPk

还有另一种方法可以做到这一点，或者我做错了吗？

抱歉，听起来确实需要重新考虑架构设计。在人们放置了太多FK之前，我已经看到了此错误，但总是会回到架构设计问题。
