这是一个简单的脚本，想实现用变量接受sql的执行结果。
执行后：
SQL*Plus: Release 11.2.0.3.0 Production on Wed Oct 28 15:41:24 2015

SQL> Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

File:16
想请问下我上面的sql语句的sum值是8042000，但是$value的值是16这是为什么啊？，我想接受到8042000该怎么做？
4 个解决方案
$?的范围是0～255，也就是，如果上一条命令返回值是8042000，那么最终结果就是8042000&255=16
