 a***o发帖数: 22 1来自主题: Database版 - disable constraintI 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.
 n********a发帖数: 68 2来自主题: Database版 - PL/SQL constraint 求教？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.
 e********0发帖数: 259 3来自主题: Economics版 - 包子请教constraint maximization问题问题是： 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。 谢谢各位！！

 r****s发帖数: 12 5来自主题: Database版 - 谁知道下面这段是什么意思（ABOUT CONSTRAINTS）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
