Using Dynamic SQL in Stored Procedures

Dynamic SQL allows stored procedures to “write” or dynamically generate their SQL statements. The most common use case for dynamic SQL is stored procedures with optional parameters in the WHERE clause. These are typically called from reports or screens that have multiple, optional search criteria. This article describes how to write these types of stored procedures so they execute well and resist SQL injection attacks.

Cannot boot: "No init found. Try passing init=bootarg"

- by glutz

After losing power, my machine rebooted to this error: “error: no init found. Try passing init=bootarg” Per similar threads on this site and others, I've tried booting from a CD and selecting "Try Ubuntu". Then open a terminal and typing: sudo fsck-y /dev/sda1. The response is: Device or resource busy while trying to open /dev/sda1. Filesystem mounted or opened exclusively by another program? This is on Ubuntu 10.10. Any ideas on what I can try next?

GlassFish Community Event @ JavaOne - Save the date!

- by alexismp

The interest for having a GlassFish community event at JavaOne is still very strong both inside Oracle and in the community, so this year again we'll be hosting a get together on the Sunday prior to the main event. If you're in town and attending JavaOne, mark your calendars : Sunday 2nd, October 2011 - 12:30pm-4:30pm in the Moscone This will be an opportunity to discuss the community status (adoption of Java EE 6, GlassFish 3.1.x) and hear about future plans, mainly around Java EE 7 and the related GlassFish release(s). We'd also like to have several participants share their deployment stories as well as some time for an free-form unconference format and some team building activity. Of course, beyond all the content shared in slides, this should really also be a good excuse to meet folks from the community and from the core GlassFish team at Oracle. Here's a post on last year's event. And before anybody asks, we are still exploring the party situation :-)

Looking for best approach to create new projects for enviroment specifics files

- by Ness

ClearCase Question... Overview of requirements: There are 3 diff environments (DEV, TEST and PROD) which have a folder called 'common' that users across all envs. There are multiple servers in those 3 envs and we want to store their server environment specific configuration files in Clearcase. The executables files are different for each environment. Thus there will not be cross delivery require between dev/test/prod. Any thoughts on how we can approach this? Is keeping it simplest is the best approach here? One component to one vobs as (DEV_Serv1, TEST_Serv1, PROD_Serv1, Dev_Serv2, Test_Serv2 and etc)? OR Have multiple components VOB? One other thing is developers here like to use snapshots views.

Facing quality issues

- by juststartedmycareer

A workforce management software has complex GUI (for example values in a page depends on the status (closed or open) of other pages). Only latest and near past development has test coverage. During our last release, we received lots of bugs from customer in-spite of 2 weeks of testing Sprint . We don't have dedicated test team. The developers does the unit test & User acceptance test. Every day triggers automated regression test. I am afraid the developers are not testing the entire workflow because its time consuming also not able to automate it because of its complexity. Any suggestions ?. The legacy code (15 yrs development) has less code coverage. How can I improve quality ? Note: Now not possible to hire testers to have independent test team!!

Cannot get grub menu to timeout (or go away)

- by Eric

I am running Ubuntu 12.04. I cannot for the life of me get the grub menu (with options) to go away. I would like it to auto-boot into the first option. I've edited /etc/default/grub so that it looks like the following: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" After this, I ran sudo update-grub. Then I realized that I had grub 2, so I ran sudo update-grub2 (both make it look like they create the grub.cfg file successfully. I restart my computer and it goes back to the grub menu and just sits there until I make a choice. This is not desirable if the power goes out... :-) I also tried reinstalling grub using sudo grub-install /dev/sda - also unsuccessful

C#.NET: How to update multiple .NET pages when a particular event occurs in one .Net page? In another words how to use Observer pattern(Publish and subscribe to events)

Problem: Suppose you have a scenario in which you have to update multiple pages when an event occurs in main page. For example imagine you have a main page where you are dispalying a tab control. This tab control has 3 tab pages where you are loading 3 different user controls. On click of an update button in main page imagine if you have do something in all the 3 tab panels. In other words an event in main page has to be handled in many other pages. An event in main page which contains the tab control has to be handled in all the tab panels(user controls) Answer: Use Observer pattern Define a base page for the page that contains the tab control. Main page which contains the tab: Baseline_Baseline Basepage for the above main page: BaselineBasePage User control that has to be udpated for an event in main page: Baseline_PriorNonDeloitte Source Code: public class BaselineBasePage : System.Web.UI.Page { IList lstControls = new List(); public void Add(IObserver userControl) { lstControls.Add(userControl); } public void Remove(IObserver userControl) { lstControls.Remove(userControl); } public void RemoveAllUserControls() { lstControls.Clear(); } public void Update(SaveEventArgs e) { foreach (IObserver LobjControl in lstControls) { LobjControl.Save(e); } } } public interface IObserver { void Update(SaveEventArgs e); } public partial class Baseline_Baseline : BaselineBasePage { . . . this.Add(_ucPI); this.Add(_ucPI1); protected void abActionBar_saveClicked(object sender, EventArgs e) { SaveEventArgs se = new SaveEventArgs(); se.TabType = (BaselineTabType)tcBaseline.ActiveTabIndex; this.Update(se); } } Public class Baseline_PriorNonDeloitte : System.Web.UI.UserControl,IObserver { public void Update(SaveEventArgs e) { } } More info at: http://www.dofactory.com/Patterns/PatternObserver.aspx span.fullpost {display:none;}

What would be a good way to request comments?

- by WarpEnterprises

In the project/team I'm working the frequency of comments is a little low. One reason might be that it is not clear to the long-time devs what lines in the code really needs a comment (each part of the project has quite fixed devs). To increase this we plan to let team members review the code and check in "requests for comments", which the main dev of that part should replace with useful comments. Do you think this could work? If "yes": what tags should we use to mark? (e.g. //TODO please comment) Can you think of alternatives for this process? Edit: I appreciate your answers about best practice in commenting and writing code, and I completey agree. But my question targets the cases where refactoring is not an option (not wanting to change working code, not wanting to "accuse" main dev of producing code that needs refactoring,...) - so only more or better comments are an option (at least for this question).

Delete all traces of windows from Ubuntu

- by TheOm3ga

I used to have a dual boot in one of my hard disk drives - Ubuntu and Windows 7. Then, I added a SSD which is now my main hard disk drive, and I'm using it for Windows 7 completely, keeping Ubuntu in the old HD. I restored the Grub so everything works ok, except for one thing. Everytime I update the grub, it detects two windows: Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 Obviously, I don't want it to detect the Windows on sdb1. Because I no longer use it (I manually deleted the files). What can I do about that without wiping out completely the partition?

Accessing controls of .aspx file in .aspx.cs without any declaration.!!??

I am able to access the controls of ".aspx" file in ".aspx.cs" directly without any declaration in ".aspx.cs" or in designer.cs. How is this possible? This is happeing only if I open website as using File System. Create a new ASP.NET web site application with Visual Studio 2008. So following three files will be created automatically "Default.aspx", "Default.aspx.cs" "Default.designer.cs" Now Delete "Default.designer.cs" perminently. Just create a button in Default.aspx file <asp:Button runat="server" Text="Save Plan" ID="btnSave" /> Close the Solution and open the website as File System. File -> Open Web Site -> File System -> Select Web Site Folder and Open the project. Now btnSave is automatically recognized in Default.aspx.cs without any declaration in Default.aspx.cs as bellow System.Web.UI.WebControls.Button btnSave; How btnSave is being recognized by .cs file without defining it anywhere as an object of System.Web.UI.WebControls.Button? Note: This happens only if you open Web Site from File System. and No Declaration at all for btnSave. Please refer this article on this. span.fullpost {display:none;}

Is my work on a developers test being taken advantage of?

- by CodeWarrior

I am looking for a job and have applied to a number of positions. One of them responded, I had a pretty lengthy phone interview (perhaps an hour +) and they then set me up with the developers test. I was told that this test is estimated to take between 6 and 8 hours and that, provided it met with their approval, I could be paid for my work on it. That gave me some pause, but I endeavored. The dev test took place on a VM accessed via RDP. The task was to implement a search page in a web project that requests data from the server, displays it on the screen in a table, has a pretty complicated search filtering scheme (there are about 15 statuses and when sending the search to the server you can search by these statuses) in addition to the string/field search. They want some SVG icons to change color on certain data values, they want some data to be represented differently than how it is in the database, etc. Loooong story short, this took one heck of a lot longer than 6-8 hours. Much of it was due to the very poor VM that I was running on (Visual Studio 2013 took 10 minutes to load, and another 15 minutes to open the 3 GB ginormous solution). After completing, I was told to commit my changes to source control... Hmm, OK. I get an email back that they thought that the SVGs could have their color changed differently, they found a bug in this edge-case, there was an occasional problem with this other thing that I never experienced, etc. So I am 13-14 hours into this thing now and I have to do bug fixes. I do them, and they come back with some more. This is all apparently going into a production application. I noticed some anomalies in the code that was already in there where it looked like other people had coded all of one functionality and not anything else that I could find. Am I just being used for cheap labor? Even if they pay me the promised 50 dollars and hour for 6 hours, I have committed like 18 hours to this thing now. If I bug fix all of the stuff they keep coming up with, I will have worked at least 16 hours for free. I have taken a number of dev tests. I have never taken one where I worked on code that was destined for production. I have never taken one where I implemented a feature that was in the pipeline for development (it was planned for, and I implemented it through the course of the test). And I have never taken one that took 4 rounds and a total of 20+ hours. I get the impression that they are using their dev test to field some of the functionality, that they don't have time for in their normal team, on the cheap. Also, I wouldn't mind a 'devtest' tag.

How do I allow a non-default user to use serial device ttyUSB0?

- by lucaghera

I have an Ubuntu 11.10 system with 2 users: The first was created during the installation The second instead was created after. It belongs to the sudoers group. Now the problem is that when the second tries to use a device ttyUSB0 the following error is returned: "Could not open serial port /dev/ttyUSB0" I was able to fix it by using: sudo chown :second_user /dev/ttyUSB0 However when I disconnect the device and reconnect it the problem comes back. Is there a way to allow different users to access the devices? I suppose I have to add the user to a specific group. Currently the owner is root and the group is dialout. However I'm not sure about the group and I don't know how to add the user. Thanks!

Migrating IBM ClearCase to TFS

Using the Team Foundation Server Integration Tools Platform. Versions: ClearCase: 7.1.1.2 Team Foundation Server: 2012 RTM Integration Tools: 2.2.20314.1 OS: Windows 2008 R2 ENT SP1 I was able to do a simple example migration of a few files by using the following approach: Using a dynamic view Creating a view shortcut drive (i.e. Z:\) Running the tools as a UI client (not as a windows service) Running the tools UI in user mode (do not “Run as Administrator”) Using the CC detailed history adapter Selecting the view shortcut drive (i.e. Z) on the Tools UI Connect to CC dialog Selecting the “Detect Changes in CC” option on the Tools UI Connect to CC dialog Changing the DisableTargetAnalysis value to True on the Tools UI configuration view I have yet to perform actual migrations for real projects, but will update this blog as I do.

Ubuntu 12.04 mdadm inactive

- by user32274

For a while now, my RAID 5 has ceased to work. Everytime I tried "madm --detail /dev/md127", its states all the drive and drive info, but that two of the drives have been removed. After some restarts, doing the same thing, i am getting /dev/md127 does not appear to be active. When I go into DiskUtil, I can see all 6 Hard Drives healthy and present, and i can see the Raid 5 at the bottom under Multi-disk Devices. However, the Raid says 0.0kb, and is not active. Please help and let me know how to proceed from here. I would really like to avoid rebuilding the RAID, especially because all 6 drives seem to be healthy and present. Thanks so much.

.NET - Where can I start? [closed]

- by mustang2009cobra

I'm a moderately experienced developer with experience developing using a variety of languages. I've done C++, Java, PHP, Javascript, and several other languages. I remember the Java dev stack being rather difficult to dive into, but it's nothing like the endless sea of the .NET framework. I'd like to become experienced in .NET development, as many dev shops are microsoft-centric. But I'm a little unsure as to where the best place to start is. As I already know a bunch of programming languages, I don't really need resources that will help me learn C# or any of the .NET languages as much as I need to learn the development stack, APIs, etc. Any suggestions on the best way to start learning .NET development?
