  • Is there something like "if not exist create sequence ..." in Oracle SQL?

    - by Timo
    Very probably a noob question: For my application that uses an Oracle 8 DB, I am providing an SQL script to setup stuff like triggers, sequences etc., which can be copied and pasted into SQL*Plus. I would like the script to not stop with an error if a sequence that I am trying to create already exists. For a Trigger this can easily be done using "create or replace trigger ...", but for a sequence this does not work. Is there some alternative, like "if not exists mysequence then create sequence ..." (I tried this but it did not work :) ) Alternatively, if this is not possible, is there a way to do a "drop sequence mysequence" without SQL*Plus aborting the script if mysequence does not exist? Thanks. PS: I wish Oracle just had a simple Autoinc field type ... sigh.

  • Is there a literal notation for decimal in IronPython?

    - by jeroenh
    suppose I have the following IronPython script: def Calculate(input): return input * 1.21 When called from C# with a decimal, this function returns a double: var python = Python.CreateRuntime(); dynamic engine = python.UseFile("mypythonscript.py") decimal input = 100M; // input is of type Decimal // next line throws RuntimeBinderException: // "cannot implicitly convert double to decimal" decimal result = engine.Calculate(input); I seem to have two options: First, I could cast at the C# side: seems like a no-go as I might loose precision. decimal result = (decimal)engine.Calculate(input); Second option is to use System.Decimal in the python script: works, but pollutes the script, which should be understandable for my users... import clr import System def CalculateVAT(amount): return amount * System.Decimal(1.21) Is there a way to tell the DLR that the number 1.21 should be interpreted as a Decimal, much like I would use the '1.21M' notation in C#?

  • Calling a protected Windows executable with Perl

    - by Jake
    I'm trying to write a perl script that determines which users are currently logged into Windows by using query.exe (c:\Windows\system32\query.exe). Perl is unable to access this file, unable to execute it, even unable to see that it exists, as I've found with the following code: print `dir c:\\windows\\system32\\query*`; This produces the following output: 07/13/2009 05:16 PM 1,363,456 Query.dll 1 File(s) 1,363,456 bytes 0 Dir(s) 183,987,658,752 bytes free I've checked the user executing the script using perl's getlogin function, and it returns the name of a member of the local Administrators group (specifically, me). I've also tried adding read/execute permissions for "Everyone", but windows keeps giving me access denied errors when I try to modify this file's permissions. Finally, I've tried running perl.exe as an administrator but that doesn't fix the problem either. Is this something I can solve by changing some settings in Windows? Do I need to add something to my perl script? Or is there just no way to grant perl access to some of these processes?

  • php mkdir windows relative path

    - by Vish
    Hi, Want to create a directory on windows from a PHP script. My script is in www/Test directory of Apache and want to create a folder(fold1) inside www/downloads directory. Inside the script, using, $dirName = "../downloads/fold1"; mkdir("{$dirName}"); If we use the full path of dirName like C:\Apache\www\downloads\fold1, it works fine. But want to use relative path since this code will be sent to the client. Please let me know. Thanks, Vish.

  • How do I switch to a SQL Server Server Database that will exist after another command?

    - by Jason Young
    I can't get this script to run, because SQL management studio 2008 says the table "NewName" does not exist. However, the script's purpose is to rename an existing database, so that it does exist when it gets to that line. Ideas? Use Master; ALTER DATABASE OldName SET SINGLE_USER WITH NO_WAIT; ALTER DATABASE OldName MODIFY NAME = NewName; ALTER DATABASE NewName SET MULTI_USER; Use NewName; --THIS LINE FAILS BEFORE THE SCRIPT EVEN RUNS!

  • How do I execute a shell-command in background?

    - by Adobe
    Here's a simple defun to run a shell script: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " &") nil nil)) If I start a program with no ampersand - it start the script, but blocks emacs until I close the program, if I don't put ampersand it gives error: /home/boris/its/plts/goodies/bk-konsoles.bash /home/boris/scl/geekgeek/: exited abnormally with code 1. Edit: So now I'm using: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " & disown") nil nil) (kill-buffer "*Shell Command Output*")) Edit 2: Nope - doesn't work: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (let ((curDir default-directory)) ;; (shell-command (concat "nohup " (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir) nil nil) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir "& disown") nil nil) (kill-buffer "*Shell Command Output*"))) keeps emacs busy - either with disown, or nohup. Here's a script I'm running if it might be of help: bk-konsoles.bash

  • Cannot load JRubyEngine because org.apache.bsf.util.BSFEngineImpl not found

    - by Ceilingfish
    Hi, I'm trying to use JRuby in a custom application, and I don't seem to be able to load the JRubyEngine object. My class looks like functionally similar to this: public class ScriptEngine { private static ScriptEngine engine = new JRubyEngine(); public void run(final String script, final Map<String,Object> input) { final Bindings context = engine.createBindings(); context.putAll(input); try { engine.eval(script,context); } catch (ScriptException e) { log.error("Failed to execute script: "+getScript(),e); } } } However this fails at compilation with the complaint: [javac] Compiling 486 source files to /workspace/myProject/build/src [javac] /workspace/myProject/src/net/ceilingfish/ScriptEngine.java:31: cannot access org.apache.bsf.util.BSFEngineImpl [javac] class file for org.apache.bsf.util.BSFEngineImpl not found [javac] private static ScriptEngine engine = new JRubyEngine(); [javac] ^ [javac] 1 error Does anyone have any insights on where I can get this class from? Or if there is a better way to be instantiating a JRubyEngine object.

  • How can I create a javascript library in a separate file and "include" it in another?

    - by Jordan L. Walbesser
    First, a caveat. The main script is not run in a webpage. I will be running the .js file in Windows using Windows Script Host. The problem: I would like to create a javascript "library" containing a number of objects, each with a number of functions. I expect this library will get rather large with time and would like to keep it in a separate javascript file (let's call it Library.js). I would like to access the objects from Library.js from another script (let's call this one User.js). In essence, I am looking for something similar to the C/C++ "include" paradigm. Is there anyway to implement this in javascript? (Remember, this is not web-based)

  • Revert scan state when prompting for variable values

    - by Dave Jarvis
    How do you detect the current SCAN state and revert it after changing it? An exerpt from the script in question: SET SCAN OFF SET ECHO ON SET SQLBLANKLINES ON SET SCAN ON UPDATE TABLE_NAME SET CREATED_BY = &&created_by; SET SCAN OFF The problem is that if the script doesn't have the first line (SET SCAN OFF), then the code to prompt the user should not turn the SCAN state off. In pseudocode, we'd like to do the following: SET SCAN OFF SET ECHO ON SET SQLBLANKLINES ON PUSH SCAN STATE SET SCAN ON UPDATE TABLE_NAME SET CREATED_BY = &&created_by; POP SCAN STATE The psudeocode PUSH SCAN STATE remembers the state so that if the code is altered by removing the first line, the rest of the script still works as expected.

  • Vbscript - Compare and copy files from folder if newer than destination files

    - by Kenny Bones
    Hi, I'm trying to design this script that's supposed to be used as a part of a logon script for alot of users. And this script is basically supposed to take a source folder and destination folder as basically just make sure that the destination folder has the exact same content as the source folder. But only copy if the datemodified stamp of the source file is newer than the destination file. I have been thinking out this basic pseudo code, just trying to make sure this is valid and solid basically. Dim strSourceFolder, strDestFolder strSourceFolder = "C:\Users\User\SourceFolder\" strDestFolder = "C:\Users\User\DestFolder\" For each file in StrSourceFolder ReplaceIfNewer (file, strDestFolder) Next Sub ReplaceIfNewer (SourceFile, DestFolder) Dim DateModifiedSourceFile, DateModifiedDestFile DateModifiedSourceFile = SourceFile.DateModified() DateModifiedDestFile = DestFolder & "\" & SourceFile.DateModified() If DateModifiedSourceFile < DateModifiedDestFile Copy SourceFile to SourceFolder End if End Sub Would this work? I'm not quite sure how it can be done, but I could probably spend all day figuring it out. But the people here are generally so amazingly smart that with your help it would take alot less time :)

  • Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

    - by mrbinky3000
    This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

  • Only some windows shell commands work via ruby?

    - by Sanarothe
    Hi. I'm trying to use a script to control my power options since XP doesn't give you an intuitive way to change CPU Frequency options. Here's my script so far: meh = `cmd.exe /C POWERCFG.EXE /QUERY Portable/Laptop` puts "" puts meh case input when 1 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac NONE') when 2 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac ADAPTIVE') when 3 then `cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac CONSTANT` end The problem is that the changes simply don't take place. If I run the same commands directly into a cmd.exe prompt, they work. It's very strange, but nothing works after the initial powercfg query. I feel like I'm missing something incredibly obvious. How can I get the above script to run correctly?

  • Register/Include javascript within RenderingTemplate.

    - by Janis Veinbergs
    Is it possible to register (include) javascript within RenderingTemplate? (RenderingTemplates are used to render list forms or fields) By using <SharePoint:RenderingTemplate ID="NewRelatedListItem" runat="server"> <Template> <span id="part1"> <SharePoint:ScriptLink Name="SPFormFieldAssistant.js" Localizable="false" /> ... </span> ... </Template> </SharePoint:RenderingTemplate> it couldn't be done - it didn't include script at HEAD area, but...: Is something wrong with my code? Althought script IS at Layouts folder and I checked with Reflector that it uses Layouts folder if Localizable='False'. I don't want this script to be loaded with every page, but only for forms. Any ideas on how this could be achieved?

Here is the problem, I want to: take the hgweb script, modify it, and run it. But I do not want to: take the hgweb script, modify it, write it to a file and redirect there. I am using Apache to run the httpd process.

  • Sliding a div across to left and the next div appears

    - by littleMan
    I have this form Im creating and when you click on the "Next" button I want to slide the next form() across to the left this is my function jQuery('input[name^=Next]').click(function () { current.animate({ marginLeft: -current.width() }, 750); current = current.next(); }); That function isn't working the way I want to. it slides the text in the container across not the whole container it could be a css problem for all I know.

  • Cannot select/edit TineMCE-generated table

    - by Rakward
    I'm currently using TinyMCE edit in my drupal-website, problem is that beneath the editor, some of the table is sticking out. If I remove the height set by javascript with firebug, it looks fine, even after resizing. So I want to remove the height with JS, I've put this function at the end of my page: $('table#edit-body_tbl').removeAttr('style'); However nothing happens. I test the function in firebug's console, it works perfectly. Basically, the problem is the JS works, but it wont do anything if I simply load it at the end of the page, even in the document.ready function. The TineMCE script is loaded before my script so I should be able to select/edit/delete elements generated by it no? Does anybody know why or how I can force the page to really load my function in the end(currently it is right in front of the -tag)? Other functions in the script work, except this thing ...

  • MinGW - cross compile tool - latest version?

    - by Petike
    At the MinGW download page you can download the "Cross-Hosted MinGW Build Tool" which is a shell script to build the "MinGW cross-compiler" so that you will be able to compile your programs on "Linux" to the "Windows" target. I have downloaded that script, run it and answered the interactive questions the script has asked me. I had to dowload some files from which one has name "gcc-core". And the "latest" version of the "gcc-core source code" I have found on that page, was "gcc-core-3.4.5-20060117-2-src.tar.gz" - so that "3.4.5" version. But on "Ubuntu Linux" I can download the precompiled "mingw32" package which is of the version "4.2.1". How is it possible that the "Ubuntu package" version of MinGW is newer than the one from the MinGW "homepage"? So which is the latest version of the "MinGW cross compile tool"?

  • ASP.NET/JavaScript: How to surround an auto generated JavaScript block with try/catch statement

    In the Script documents that asp.net automatically generates how can I surround the whole generated scripts with try/catch statement to avoid 'Microsoft JScript Compilation error' My issue is: i got a DevExpress control (ASPxGridView) that added and set-up in run time, since i activated the grouping functionality in the grid I still get JS error says ';' expected whenever i use (click) on one of grouping/sorting abilities, I activated script Debugging for IE, in the JS code turns out that there is no missing ';' and once i click ignore for the error msg that VS generates every thing works fine, and surly end-user can't see this msg so i figured out if i try/catch the script that may help avoid this error.

  • Preload Images with javascript

    - by user271619
    Here is my preload script: <script type="text/javascript"> Image_1 = new Image(1,1); Image_1.src = "images/sprites.png"; </script> And it works fine. I can see in the headers the image loading. Here's my question. Even though I have preloaded sprites.png, I notice that when I go to a page on my site that simply displays that entire image, the headers tell me my browser is requesting the server to send the image again. I'm hoping to not sound too naive. But, why would the browser request the image when I preloaded it earlier? Are there other reasons the browser would need to re-request? Also, I put the dimensions as Image(1,1). Sometimes I don't know the dimensions, as that image gets updated from time to time. Maybe that's a reason?

  • SH/BASH - Scan a log file until some text occurs, then exit. How??

    - by James
    Current working environment is OSX 10.4.11. My current script: #!/bin/sh tail -f log.txt | while read line do if echo $line | grep -q 'LOL CANDY'; then echo 'LOL MATCH FOUND' exit 0 fi done It works properly the first time, but on the second run and beyond it takes 2 occurrences of 'LOL CANDY' to appear before the script will exit, for whatever reason. And although I'm not sure it is specifically related, there is the problem of the "tail -f" staying open forever. Can someone please give me an example that will work without using tail -f? If you want you can give me a bash script, as OSX can handle sh, bash, and some other shells I think.
