练习② 两位两位数乘整十(或整百)数,可以用两位数乘整十(或整百)数中“0”前面0000两位数乘整十(或整百)数,可以用两位数乘整$$ 3 \times 2 5 = $$的数,再在所得的积的末尾添上一个(或两个)0。如$$ 3 0 0 \times 2 5 . $$75,再在75后面添上两个0,即3$$ 3 0 0 \times 2 5...
问题分析:服务端无法处理字符串中的'\0'字符,'\0'即数值0x00、UTF编码'\u0000'的 字符串。 处理方法:排查客户执行的sql中是否包含'\0'字符,去掉特殊字符,可用空格代替。2.4 性能问题在processResult 阶段耗时 设置loglevel=3,打开JDBC日志,主要耗时在processResult阶段,可分为两种情况: 1. JDBC端等待数据库返...

BIOS的最后一条指令:JMP 0000:7C00 CS:0000 IP:7C00 接力棒即将交出给MBR。本节的代码在MBR控制之后。 MBR:将硬盘中的loader.S代码读入内存,跳转到代码内存位置,执行loader.S,将接力棒交给loader.S MBR中的代码:将硬盘中的loader.S代码读入内存,跳转到代码内存位置,执行loader.S。(核心)以下是三个实例程序。
