Preface: First, what is the convex package.Suppose the plane has a total of 13 points, p0~p12 some points as a polygon, so that the polygon can be "wrapped" all the points. When this polygon is a convex polygon, we call it "convex package". The following figure: Then, what is the convex package problem.We put these points in a two-dimensional coordinate system, so each point can be represented by (X,y).Now give the number of points 13, and the coordinates of each point. Find the point that make

A check constraint is an inspection constraint that, when using a check constraint, checks every data entered, and only records that meet the criteria are saved to the table, guaranteeing the validity and completeness of the data.Check constraints have the following four characteristics:In an expression of a check constraint, one or more columns in the table must be referenced, and the result of the expression's operation is a Boolean value.In a single column, you can define multiple check const

In the above class window, RefCountedObject is the derived class of window.Encapsulate the counter ref_count _.

are divided into prefix local indexes and non-Prefix local indexes. What is a local index with a prefix? A local index with a prefix contains the partition key and uses it as the index of the boot column. What is a local index without a prefix? A local index without a prefix does not use the leading column of the partition key as the index of the leading column of the index. The following is an example: Create table test (id number, data varchar2 (100 ))Partition by RANGE (id)(Partition p1 val

Oracle check ConstraintsA check constraint is a check constraint. When a check constraint is used, each input data is checked. Only records that meet the conditions are saved in the table, this ensures Data Validity and integrity.Check constraints have the following four features:In the expression of the check constraint, one or more columns in the table must be referenced, and the operation result of the expression is a Boolean value.Multiple check constraints can be defined in one column type.
