我尝试使用以下方法刷新物化视图:

DBMS_MVIEW.REFRESH('v_materialized_foo_tbl')

但是它抛出了无效的sql语句.

然后我创建了一个这样的存储过程:

CREATE OR REPLACE 
PROCEDURE MAT_VIEW_FOO_TBL 
IS
BEGIN
   DBMS_MVIEW.REFRESH('v_materialized_foo_tbl')
END MAT_VIEW_FOO_TBL IS;

此过程已成功创建,但在我调用此过程时

MAT_VIEW_FOO_TBL;

它再次抛出错误.

请为此问题提出解决方案.

谢谢,Srinivas

我一直在图像库[html5]上工作,它在桌面版本中运行良好我想为Ipad/Tablet设备添加基于触摸的事件.

你能否建议如何使用javascript/jquery添加基于触摸的事件.

谢谢,Srinivas

Backbone js模型集和保存方法有什么区别？

var book = new Backbone.Model({
           title: "The Rough Riders",
           author: "Theodore Roosevelt"
});

book.save({author: "Teddy"});

book.set("title", "A Scandal in Bohemia");

根据官方骨干js文档页面,它被描述为通过委托Backbone.sync将模型保存到数据库中.这是这些方法之间的唯一区别吗？

谢谢,

我刚开始学习node.js,我已经安装了node.js和npm模块管理器.我创建了一个package.json文件,并从根目录iam尝试执行npm install命令,而不是创建npm_modules文件夹,它会抛出这样的错误:
