1、修改Oracle最大连接数的方法
a、以sysdba身份登陆PL/SQL 或者 Worksheet
b、查询目前连接数
show parameter processes;
c、更改系统连接数
alter system set processes=1000 scope=spfile;
......
对于外连接，Oracle中可以使用“(+)”来表示，9i可以使用LEFT/RIGHT/FULL OUTER JOIN，下面将配合实例一一介绍。
1. LEFT OUTER JOIN：左外关联
SELECT e.last_name, e.department_id, d.department_name
from employees e
LEFT OUTER JOIN department ......
