9.0开始新增了下面特性:
Enhancements in PL/SQL Developer 9.0
====================================
* Multiple simultaneous connections
* New Connection List
* XLSX format support (Excel 2007 / 2010) for the SQL Window and Report�0�2
也就是每个windows都可以有自己的连接,不必受限于一个。这样确实省却了在多个PL/SQL Developer进程间的切换,但也带来一个严重的潜在问题:你运行SQL或脚本的时候没注意选错了windows,一个drop或trunctae、update将生产库里面的数据给清了,哭去吧。。。
有此顾虑的同学们,请一定在【参数】设置中,将此选项禁用:
[Tools] -> [preferences] ->�0�2[connection]->[Multiple connections] :
“Allow Multiple connections”
