最近公司开始上手oracle数据库了，作为一个只会使用mysql的感到一丝窃喜，多会一些东西，以后的路也好走一些。废话不多说，开始填坑。
数据库要求，导入一个文件 如图：

sql.sql文件这折算下来150MB （158465/1024），本以为是一个小case。
打开oracle sql developer ，

1.直接点击导入 ：

重点来了: 没有为sql类型注册的读进程
报错了，网上搜索没有找到较好的解决措施。

2.使用文本编辑器打开:

直接拷贝sql语句内容，放入sql developer里面去运行，发现内容多了 ，复制后粘贴没反应，额。。。。冷汗直流。。。

3.sql developer直接打开sql文件:

这样总可以了吧，额，直接来个outOfMemory 显示jvm的堆内存溢出。。。醉了。

详细错误：

解决方案：

还好有一个命令行导入的 没有这种限制，这个直接使用命令行与oracle交互了。这个命令行交互其实也是一种另类的客户端。
。
1）windows这边直接进入cmd模式，额linux直接就行了。我这边因为是虚拟机安装的oracle，所以直接把文件拷贝到虚拟机里面去了，在虚拟机里面执行，进入虚拟机(windows xp)里面。（执行cmd）
2)敲命令 sqlplus 用户名/密码@ip:端口/数据库实例 先使用命令行连接上再说吧，
如： sqlplus system/[email protected]:1521/oraclelates
3) 然后进入命令行的客户端模式了
显示 SQL>
接着输入： SQL> @E:/sql.sql;
输入的是这种格式： @全路径/sql文件
注： sql文件里面最后以一个提交 commit;
然后脚本文件就跑起来了，哈哈哈 鹅鹅鹅 成功了！so easy!
开始入坑oracle，接着就要熟悉其他相关的了。
