  • SQL Server: Check if table exists

    - by Vincent
    I would like this to be the ultimate discussion on how to check if a table exists in SQL Server 2000/2005 using SQL Statement. When you Google for the answer, you get so many different answers. Is there an official/backward & forward compatible way of doing it? Here are two ways to start discussion: IF EXISTS (SELECT 1 FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE' AND TABLE_NAME='mytablename') SELECT 1 AS res ELSE SELECT 0 AS res; IF OBJECT_ID (N'".$table_name."', N'U') IS NOT NULL SELECT 1 AS res ELSE SELECT 0 AS res; MySQL provides a nice SHOW TABLES LIKE '%tablename%'; statement. I am looking for something similar.

  • Jquery - Loading a page with .load and selector doesn't execute script?

    - by PirateKitten
    I'm trying to load one page into another using the .load() method. This loaded page contains a script that I want to execute when it has finished loading. I've put together a barebones example to demonstrate: Index.html: <html> <head> <title>Jquery Test</title> <script type="text/javascript" src="script/jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('#nav a').click(function() { $('#contentHolder').load('content.html #toLoad', '', function() {}); return false; }); }); </script> </head> <body> <div id="nav"> <a href="content.html">Click me!</a> </div> <hr /> <div id="contentHolder"> Content loaded will go here </div> </body> </html> Content.html: <div id="toLoad"> This content is from content.html <div id="contentDiv"> This should fade away. </div> <script type="text/javascript"> $('#contentDiv').fadeOut('slow', function() {} ); </script> </div> When the link is clicked, the content should load and the second paragraph should fade away. However it doesn't execute. If I stick a simple alert("") in the script of content.html it doesn't execute either. However, if I do away with the #toLoad selector in the .load() call, it works fine. I am not sure why this is, as the block is clearly in the scope of the #toLoad div. I don't want to avoid using the selector, as in reality the content.html will be a full HTML page, and I'll only want a select part out of it. Any ideas? If the script from content.html was in the .load() callback, it works fine, however I obviously don't want that logic contained within index.html. I could possibly have the callback use .getScript() to load "content.html.js" afterwards and have the logic in there, that seems to work? I'd prefer to keep the script in content.html, if possible, so that it executes fine when loaded normally too. In fact, I might do this anyway, but I would like to know why the above doesn't work.

  • Which type of design pattern should be used to create an emulator?

    - by Facon
    I have programmed an emulator, but I have some doubts about how to organizate it properly, because, I see that it has some problems about classes connection (CPU <- Machine Board). For example: I/O ports, interruptions, communication between two or more CPU, etc. I need for the emulator to has the best performance and good understanding of the code. PD: Sorry for my bad English. EDITED: Asking for multiple patterns.

  • How to get a list of all Subversion commit author usernames?

    - by Quinn Taylor
    I'm looking for an efficient way to get the list of unique commit authors for an SVN repository as a whole, or for a given resource path. I haven't been able to find an SVN command specifically for this (and don't expect one) but I'm hoping there may be a better way that what I've tried so far in Terminal (on OS X): svn log --quiet | grep "^r" | awk '{print $3}' svn log --quiet --xml | grep author | sed -E "s:</?author>::g" Either of these will give me one author name per line, but they both require filtering out a fair amount of extra information. They also don't handle duplicates of the same author name, so for lots of commits by few authors, there's tons of redundancy flowing over the wire. More often than not I just want to see the unique author usernames. (It actually might be handy to infer the commit count for each author on occasion, but even in these cases it would be better if the aggregated data were sent across instead.) I'm generally working with client-only access, so svnadmin commands are less useful, but if necessary, I might be able to ask a special favor of the repository admin if strictly necessary or much more efficient. The repositories I'm working with have tens of thousands of commits and many active users, and I don't want to inconvenience anyone.

  • (Oracle Performance) Will a query based on a view limit the view using the where clause?

    - by BestPractices
    In Oracle (10g), when I use a View (not Materialized View), does Oracle take into account the where clause when it executes the view? Let's say I have: MY_VIEW = SELECT * FROM PERSON P, ORDERS O WHERE P.P_ID = O.P_ID And I then execute the following: SELECT * FROM MY_VIEW WHERE MY_VIEW.P_ID = '1234' When this executes, does oracle first execute the query for the view and THEN filter it based on my where clause (where MY_VIEW.P_ID = '1234') or does it do this filtering as part of the execution of the view? If it does not do the latter, and P_ID had an index, would I also lose out on the indexing capability since Oracle would be executing my query against the view which doesn't have the index rather than the base table which has the index?

  • Access 2003 VBA: Return only the index of the last item selected in a ListBox

    - by Eric D. Johnson
    I will preface this with saying, this is my first time using listboxes and earlier posts were criticized for lacking detail. So, all help is greatly appreciated and I hope this is enough information without being overkill. Currently, I have a listbox updating a junction table with an on click event (iterates through selected items and if they are not in the table it adds them). The list box is also updated by an option group (based on the option group value a query populates the list with the appropriate items and they are selected/highlighted based on the junction table). Also, when items are a "sub-category" the "category" is also selected. This functions perfectly until I ask it to do more... Problem 1: I need to differentiate "categories" of items from each other. So, I have included a blank item to the list box to add a space between categories. When the blank items are present the listbox does not update the junction table properly and vice versa. Problem 2: My users want to be able to deselect the "category" under certain circumstances. This is fine, just de-select the "category" after the "sub-category" is selected. However, the "category" is re-selected whenever the listbox is clicked again because it iterates through all entries. Perceived solution for both problems: Return only the index of the item (de)selected and manipulate accordingly. Is this possible? If so, how? OR: Should I take a different approach?

  • syslogd: Logfile format (not configuration format)

    - by chris_l
    Hi, I'd like to parse logfiles. Is the logfile format of syslogd the same for all systems? On my system (Debian Lenny), it's: Mar 7 04:22:40 my-host-name ... (I'm not much interested in the ... part) Can I rely on this? And is there maybe some more-or-less official description? The manpage of syslogd describes the config format, but not the logfile format. Ideally, the description would give the fields official names like (date, time, host, entry) or (datetime, hostname, message). Maybe additionally some regular expressions. I'd like to use the names and regexes in my script, to avoid an unnecessary deviation from the standard, and to make sure, that the script runs everywhere. Thanks Chris

  • For kvm host images. GFS2 or OCFS2 with drbd8?

    - by yvess
    I want a shared filesystem on top of drbd8 on two nodes. The servers run ubuntu 9.10. I googled a lot, but couldn't find an clear trend what the web community prefers. It's seems that OCFS2 is more used at the moment. Which filesystem is more reliable, faster? GFS2 or OCFS2? Is the linux community going more towards GFS2 or OCFS2? Which of this two is better supported by ubuntu 9.10? Are there better (or more common) alternatives?

  • NetInstall working on some systems, not working on others

    - by cduruk
    Hi, I'm having an issue where my NetInstall setup works on some computers and fails on others. I am not able to diagnose the issue. I created an image of a Mac Mini and then created a NetRestore image using the System Image Utility found on Snow Leopard Server. NetBoot and NFS all seem to be working fine on the server, which is an XServe. Then I select the NetInstall image from the Startup Disk on a machine. On some of the machines, the process works as expected. On some of them, I see the globe icon blink a few times and then the system boots to the regular hard drive. I have captured the tracedump and the system.log logs from the server on both cases where NetInstall seems to work and fail. Here is the link that has all the logs http://gist.github.com/232232 The gist of the failure seems to be from the lack of BSDP DISCOVER in the failure but I'm not able to identify why that exactly is happening. I'd really appreciate any help on this issue.

  • Warning: E-Business Suite Issues with Sun JRE 1.6.0_18

    - by Steven Chan
    Users need a Java client to run the Forms-based content in Oracle E-Business Suite.  With Oracle JInitiator 1.3 out of Premier Support as of July 2009, Apps users must run the native Sun Java Runtime Engine (JRE) to access this content.In early 2008 we relaxed our certification and support policy for the use of the native Sun JRE clients with the E-Business Suite. The policy reflected a switch from certifying specific JRE versions for the E-Business Suite to specifying minimum versions, instead. This permits E-Business Suite users to run any JRE release above following minimum certified levels, even later ones that Oracle hasn't explicitly tested with the E-Business Suite: JRE 1.5.0_13 and higherJRE 1.6.0_03 and higherUnder our current policy, Oracle E-Business Suite end-users can upgrade their JRE clients whenever Sun releases a new JRE release on either the 1.5 or 1.6 versions. EBS users do not need to wait for Oracle to certify new JRE 1.5 or 1.6 plug-in updates with the E-Business Suite.Known E-Business Suite Issues with JRE 1.6.0_18We test every new JRE release with both E-Business Suite 11i and 12.  We have identified a number of issues with JRE 1.6.0_18.  If you haven't already upgraded your end-users to JRE 1.6.0_18, we recommend that you to keep them on a prior JRE release such as 1.6.0_17 (6u17).

  • example of a utf-8 format octet string

    - by erik
    I'm working w/ a function that expects a string formatted as a utf-8 encoded octet string. Can someone give me an example of what a utf-8 encoded octet string would look like? Put another way, if I convert 'foo' to bytes, I get 112, 111, 111. What would these char codes look like as a utf-8 encoded octet string? Would it be "0x70 0x6f 0x6f"? Thanks

  • Book recommendation for learning server management and Apache

    - by japancheese
    Hello, I'm currently managing a site that I feel could be optimized and utilized to be much faster, however, I'm having difficulty finding reliable information to do it. I find the Apache documentation to be a hard read, and too technical about things I don't have a strong grasp on. I'm just looking for a good beginner/intermediate book about server administration to learn as much as possible about Apache, as well as how to create a nice secure, robust server that doesn't crash at the first hint of unusual traffic surges. Thanks to anyone who can point me in the right direction.

    I use ToolBar for my WPF application. As I understand, there is no easy way to make it floating. I just want to remove element which I don't want to be displayed: several dots in the left side of ToolBar. Is there any Properties to customize view of ToolBar? Or, maybe, it's possible to redefine a ToolBar Template?

  • No download dialog with FileResult

    - by majkinetor
    I am returning File result from action triggered by the form post event. I can't get download dialog. Instead, if I use: return File(Encoding.UTF8.GetBytes(reportPath), "text/plain", "Report.csv"); I get path to the file upon ajax execution in the target div. When I use return File(reportPath, "text/plain", "Report.csv"); I get content of the file in the target div. Any thoughts ? The action is declared as [HttpPost] public virtual ActionResult ExportFilter(Model model) { string outputFile = CreateReport(model); return File(....) }

  • How do I normalise this database design?

    - by Ian Roke
    I am creating a rowing reporting and statistics system for a client where I have a structure at the moment similar to the following: ----------------------------------------------------------------------------- | ID | Team | Coaches | Rowers | Event | Position | Time | ----------------------------------------------------------------------------- | 18 | TeamName | CoachName1 | RowerName1 | EventName | 1 | 01:32:34 | | | | CoachName2 | RowerName2 | | | | | | | | RowerName3 | | | | | | | | RowerName4 | | | | ----------------------------------------------------------------------------- This is an example row of data but I would like to expand this out to a Rowers table and Coaches table and so on but I don't know how best to then link that back to the Entries table which is what this is. Has anybody got any words of wisdom they could share with me? Update A Team can have any number of Coaches and Rowers, a Rower can be in many Teams (Team A, B, C etc) and a Team can have many Coaches.

  • How to encrypt in VBScript using AES?

    - by Jon
    I am looking to encrypt some data using Rijndael/AES in VBScript using a specific key and IV value. Are there any good function libraries or COM components that would be good to use? I looked at CAPICOM; it allows a passphrase only, and won't allow setting specific key and IV values.

  • BlackBerry barcode scanning library?

    - by Mat Nadrofsky
    Anyone got a good handle on a barcode scanning library that can be used to read in UPC-A, EAN-13 or other major barcode formats based on input from the digital camera? Does RIM have a standard library already available for this? I know that BlackBerry Messenger has 2D barcode scanning built-in so I'm guessing there must be something available, though not sure if it's proprietary or not.
