发帖数: 22 | 1 I have a lot of constraints mounted with my tables. Before I exported data
into those tables, I'd like to diable all of the constraints at the same time.
does anybody have good method to diable all of the constraints at the same time
and then enable them after exporting. thanks in advance. |

发帖数: 68 | 2 Check constraint can only be enforced on a table.
And you can define constraints on the leaf-level scalar attributes of a column
object.
However, in your case, Polygons.Lines is a table collection of objects.
I don't think you declare a simple check constraint.
Use trigger to iterate each member of Polygons.Lines and check for error
conditions
create or replace trigger trig_polygons
after insert or update on Polygons
for each row
begin
for i in 1..:new.Lines.count loop
if :new.Lines(i).SP. |

发帖数: 259 | 3 问题是：
max F(x,y,z)
s.t.: a(x,y,z)<=a0 (<=表示小于或等于)
b(x,y,z)<=b0
c(x,y,z)<=c0
已知是：
对于unconstraint problem:
max F(x,y,z)
其solution: x*,y*,z*满足以下条件：
a(x*,y*,z*)>=a0 (>=表示大于或等于)
b(x*,y*,z*)>=b0
c(x*,y*,z*)>=c0
目的是:
判断inequality constraints是否binding.
直觉上好像应该bind,不过不知道有没有类似的定理可以用于证明的。
如果这个问题没有确定的答案，欢迎对F,a,b,c的性质进行假设。
或者能提供一本概括constraint maximization高级定理（Simon& Blume
没有相关深度的内容）的书也很有帮助。
一个有用的信息点给一个包子，完整的解出给三个。
另外：
求constraint maximization的高手，进行线下付费咨询。

发帖数: 12 | 5 keys are attributes or sets of attributes that uniquely identify an
object within its class or an entity within its entity set.no two
objects in a class may agree in their values for each of a set of
attributes that constitutes a key.
single-value constraints are requirements that the value in a certain
role be unique,keys are a major source of single-value constraints,since
they require that associated with value(s) for the key attribute(S) are
unique values of the other attributes of the call |

发帖数: 10908 | 34 其实 “猴版 intuitional constrained optimization” +
“猴版 intuitional transformation geometry” 的直觉，
也能算很严格了。比如这么解释：
（1）这题两个 constraint 是 “大正方形” 加 “四个小正方形”。
constraint 90 度旋转对称。constraint 的要求是 no-intersection。
（2）所以满足 constraint 的最大的正方形的中心，必然在旋转对称点。
（3）而正方形中心固定之后，在给定的倾角 alpha，在该倾角下找到
最大的正方形，那就是个 trivial problem。
（4）所以问题就是找到最大正方形所对应的倾角 alpha，于是绕场一周
就完事了。（其实因为 90 度旋转对称，绕场 1/4 圈就够了）。
但是问题就是中学老师不认猴版 intuitional，中学娃也说不清猴版
intuitional。
