快速SQL Server问题 [英] Quick SQL Server question

问题描述

有人可以向我解释这在SQL中的作用吗?
print(512&511)-数字的值不重要，可以是任意两个.

Could someone explain to me what this does in SQL:
print (512 & 511) - values of the numbers not important, could be any two.

推荐答案

这是按位运算.检查一下.

It is bitwise operation. Check this.

AFAIK，这将基于512和511之间的按位&(and)操作打印整数.

AFAIK, this will print an integer based on a bitwise &(and) operation between 512 and 511.
