用Venn diagramm很好理解. 这是源的链接.有一个很好的描述. 你的第二张照片表明,当它们不是时,两者是相互排斥的.图片应该与第一次显示相同,但第二次显示"交叉椭圆"`()`.实际上,在第二个想法,因为'union all`结果不是一个集合,你不应该尝试使用维恩图绘制它!(5认同) ...

Venn Diagram of Union of Sets Let us consider a universal set U such that A and B are the subsets of this universal set. The union of two sets A and B is defined as the set of all the elements which lie in set A and set B or both the elements in A and B altogether. The uni...
对于SQL的Join,在学习起来可能是比较乱的。我们知道,SQL的Join语法有很多inner的,有outer的,有left的,有时候,对于Select出来的结果集是什么样子有点不是很清楚。Coding Horror上有一篇文章,通过韦恩图(Venn diagram,可用来表示多个集合之间的逻辑关系)。解释了SQL的Join。我觉得清楚易懂,转过来。
The intersection of sets A and B, written as {eq}A \cap B {/eq}, results in the set {eq}A \cap B {/eq} = {4, 10}, and a Venn diagram, like the ones pictured in Figure 1 and Figure 2, is a straightforward geometric way to visualize the union and the intersection of sets...

Find the number using the following Venn diagram: {eq}n(A \cup B^C) {/eq}. Union of sets: A union between two sets {eq}A {/eq} and {eq}B {/eq} is an operation between {eq}A {/eq} and B that results in a third set {eq}C {/eq} that contains all the elem...
The intersection of two sets is the set of elements in both the first set and the second set. The symbol used for the intersection of two sets is: ∩ Here is an image of two sets in Figure 1 along with the union and intersection of them: Fig. 1: Venn diagram of two sets ...
