• Oracle: show parameters on error

  - by llappall

  When Oracle logs a parameterized SQL query failing, it shows "?" in place of the parameters, i.e. the query before replacing parameters. For example, "SELECT * FROM table where col like '?'" SQL state [99999]; error code [29902]; ORA-29902: error in executing ODCIIndexStart() routine ORA-20000: Oracle Text error: DRG-50901: text query parser syntax error on line 1, column 48 Is there a way to change logging so it shows the parameter values? The information above is absolutely useless unless I can see what the actual parsing problem was. In general, is there a way to set logs in Oracle to show parameters in parameterized query errors?

• WCF Business logic handling

  - by Raj

  I have a WCF service that supports about 10 contracts, we have been supporting a client with all the business rules specific to this client now we have another client who will be using the exact same contracts (so we cannot change that) they will be calling the service exactly the same way the previous client called now the only way we can differentiate between the two clients is by one of the input parameters. Based on this input parameter we have to use a slightly different business logic – the logic for both the Client will be same 50% of the time the remainder will have different logic (across Business / DAL layers) . I don’t want to use if else statement in each of contract implementation to differentiate and reroute the logic also what if another client comes in. Is there a clean way of handling a situation like this. I am using framework 3.5. Like I said I cannot change any of the contracts (service / data contract ) or the current service calling infrastructure for the new client. Thanks

• Preventing focus on next form element after showing alert using JQuery

  - by digitalsanctum

  I have some text inputs which I'm validating when a user tabs to the next one. I would like the focus to stay on a problematic input after showing an alert. I can't seem to nail down the correct syntax to have JQuery do this. Instead the following code shows the alert then focuses on the next text input. How can I prevent tabbing to the next element after showing an alert? $('input.IosOverrideTextBox').bind({ blur: function(e) { var val = $(this).val(); if (val.length == 0) return; var pval = parseTicks(val); if (isNaN(pval) || pval == 0.0) { alert("Invalid override: " + val); return false; } }, focus: function() { $(this).select(); } });

• Connecting To SQL Database In C#

  - by Soo

  Hey everyone, I'm pretty familiar with SQL syntax (via MySQL) and am just getting my feet wet with C# and SQL server. I currently have a .sdf database on my C:\ drive and want to connect to it in C#. I added the database as a data source and now need help figuring out how to get data from the database in my C# application. I just want to be able to set an object to the data in my SQL database so I can manipulate it using C#. Thanks in advance for replies.

• Clean URLs for static HTML files with .htaccess and mod_rewrite

  - by alistair.mp

  Hello. mod_rewrite always baffles me... can anyone tell me the rules I need to get the following clean URLs? Desired URL on the left, real URL on the right. /our-work/ => /our-work.html /our-work/some-project/ => /our-work/some-project.html /contact/ => /contact.html As you can see, I want to force trailing slashes on all URLs too. Thanks!

• accessing google maps via UIWebView - illegal?

  - by Karin

  New to iPhone development. Working on first app. I'm accessing google maps via UIWebView to forward geocode an address using "http://maps.google.com/maps?q=my address". It works, although it has this quirk of requiring you to hit "Back" button and then the "Detail" button (provided by the navigation bar) to get back to the screen from whence you started. If anyone knows why it does this, I'd love to hear. My real question, however, is this a legal use of google maps? Since I intend this app for commercial use, am I violating Google's rules + regs? If it is illegal, what's my alternative? Thanks.

• REST/ROA Architecture - Send database search/querying/filter/sorting parameters in URL? (>, <, IN, e

  - by DutrowLLC

  I'm building a REST interface to my application using ROA (Resource Oriented Architecture) . I'd like to give the client the ability to specify search parameters in URL. So a client could say "Give me all people who's: "first_name" is equal to "BOB" "age" is greater than "30" sort by "last_name" I was thinking something like: GET /PEOPLE/{query_parameters}/{sort_parameters} ...or perhaps GET /PEOPLE?query=<query_string>&sort=<sort_string> ...but I'm unsure what syntax would be good for specifying in the COLUMN_NAME-OPERATOR-VALUE triplicates. I was thinking perhaps something like: column_name.operator.value So the client could say: GET /PEOPLE?query=first_name.EQUALS.bob&query=age.GREATER_THAN.30&sort=last_name.ASCENDING I really don't want to re-invent the wheel here, are there some accepted ways that this is done? I am using Restlets, I don't know if that makes a difference.

• WPF DataGrid row validation error count

  - by SuperFloh1234

  Hi! I'm currently facing the problem, that I import an Excel file to a DataGrid. This works pretty fine, but after importing the table, I need to know how many rows are invalid. I have applied several validation rules for the different datatypes, and I have an icon in the row header, that shows up if the row is invalid. But since I have more that 10.000 rows in the grid, I don't want scroll all the way through it to find the errors. Any ideas, how to determine the count of invalid rows (and then maybe bind that to a textbox)? Thx

• C++/CLI com-Interop: Exposing a reference type property to VBA

  - by Adam

  After long hours of investigation on exposing C# property that accepts a reference type to VBA, I concluded that it was not possible. In brief, a C# property that is of type double[] or even an object cannot be consumed in VBA like this: ' Compile Error: Function or interface marked as restricted, ' or the function uses an Automation type not supported in Visual Basic oComExposedEarlyBinding.ObjectArray = VBArray ' Run-time error 424: Object required oComExposedEarlyBinding.PlainObject = VBArray Or for more details: C# property exposed to VBA (COM) : Run-time error '424': Object required I would like to know if C++/CLI would support such an option? i.e. Allowing a reference-type property to be exposed to VBA so that a syntax like the above is valid. N.B. You can achieve this by using late binding, but losing the intellisense is not an option.

• Getting javascript mouse position relative to website prefferably without jQuery

  - by Constructor

  I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

• How did Perl gain a reputation for being a write-only language?

  - by Andrew Grimm

  How did Perl gain a reputation (deserved, undeserved, or used to be deserved, no longer so) of being a "write only language"? Was it The syntax of the language Specific features that were available in the language Specific features not being available in the language (or at least old versions of it) The kind of tasks Perl was being used for The kind of people who use Perl (people who aren't full-time programmers) Criticism from people committed to another language Something else? Background: I'd like to know if some aspects that gave Perl the reputation of being write-only also apply to other languages (specifically ruby). Disclaimer: I recognise that Perl doesn't force people to do write-only code (can any language?), and that you can write bad code in any language.

• Accessing E4X nodes having special characters in name without breaking binding chain in flex.

  - by Jonas

  I am using E4X to bind some values from xml in flex 3. There is a problem when xml tag's (or attribute's) name has special character in it: having xml content var xml:XML = <tag> <special-name att="val" /> </tag> special-name could not be accessed using xml.special-name.@att because it is interpreted as subtraction, on the other hand using square bracket notation xml['special-name'].@att breaks binding chain. Is there an elegant way to solve this (like special language syntax) without writing custom binding setters and listeners?

• postgres store with composite value type, or a better way of attributing an inverted index

  - by Hassan Syed

  can't seem to figure out the syntax for populating a hstore with a value of composite type -- note: I do not want to convert a record to a hstore. select hstore('hello => ROW(1,2)'); I know it's something simple; However, google is not my friend today. use case : custom inverted index. The data is modelling an inverted index of lexemes, the composite data types are various probabilities related to the lexemes which I will use to implement document clustering. Does anyone know a better way of doing this ? I'm open to using an external system if it allows attaching attributes to key-posting pairs in the inverted index. I'd use something external if it had solid support for what I am trying to do, I suspect that sticking 3-10k lexemes per tuple and then doing batch processing on them is gonna be nasty as the whole hstore will have to be parsed and converted .

• What build param(s) to use so VS 2010 can gen .obj & link .objs but NOT create an .exe?

  - by Csourcecode

  Question title pretty much asks it all. I know I could set the project to be a .lib build and have it fail to build/link a .lib .... and the .objs tend to be in the appropriate config dir That seems like a shi*-a** backdoor way to get VS to gen objs Is there a flag/param I can set somewhere in the property sheet properties/options for Visual Studio so it links what it needs to & gens the respective objs for each source file? It's so freaking easy to just gen object files using gcc (and link in appropriate lib routines WITHOUT creating an executable) ... I'm sure I could also hack up a custom build rule but that seems like overkill [and since I'm not up to speed on the build rules for whatever version of make VS 2010 is using it's easier to ask someone else here for the simple solution]

• Does anyone change the Visual Studio default bracing style in C# - Is there a standard?

  - by El Ronnoco

  I find the default bracing style a bit wasteful on line count eg... function foo() { if (...) { ... } else { ... } } would, if I was writing in JavaScript for example be written like... function foo() { if (...) { ... } else { ... } } ...which I understand may also not be to peoples' tastes. But the question(s) is/are do you turn off the VS formatting style and use your own rules? What is the opinion of this in the industry when many people are working on the same code-base? Is it better just to stick to the default just for simplicity/uniformity?

• Rack::ResponseHeaders in rackup for Sinatra

  - by sevennineteen

  I think this is a very easy one, but I can't seem to get it right. Basically, I'm trying to use Rack middleware to set a default Cache-Control header into all responses served by my Sinatra app. It looks like Rack::ResponseHeaders should be able to do exactly what I need, but I get an error when attempting to use the syntax demonstrated here in my rackup file: use Rack::ResponseHeaders do |headers| headers['X-Foo'] = 'bar' headers.delete('X-Baz') end I was able to get Rack::Cache to work successfully as follows: use Rack::Cache, :default_ttl => 3600 However, this doesn't achieve exactly the output I want, whereas Rack::ResponseHeaders gives fine-grained control of the headers. FYI, my site is hosted on Heroku, and the required Rack gems are specified in my .gems manifest. Thanks! Update: After doing some research, it looks like the first issue is that Rack::ResponseHeaders is not found in the version of rack-contrib (0.9.2) which was installed. I'll start by looking into that.

• How does mysql define DISTINCT()

  - by goran

  AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best

• INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE

  - by dnagirl

  I'm doing an insert query where most of many columns would need to be updated to the new values if a unique key already existed. It goes something like this: INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, inact, inadur, inadist, smlct, smldur, smldist, larct, lardur, lardist, emptyct, emptydur) SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, t.inact, t.inadur, t.inadist, t.smlct, t.smldur, t.smldist, t.larct, t.lardur, t.lardist, t.emptyct, t.emptydur FROM tmp t WHERE uid=x ON DUPLICATE KEY UPDATE ...; //update all fields to values from SELECT, except for exp_id, created_by, location, animal, starttime, endtime I'm not sure what the syntax for the UPDATE clause should be. How do I refer to the current row from the SELECT clause?

• When should I use static methods in a class and what are the benefits?

  - by NAVEED

  I have concept of static variables but what are the benefits of static methods in a class. I have worked on some projects but I did not make a method static. Whenever I need to call a method of a class, I create an object of that class and call the desired method. Static variable in a method holds it's value even when method is executed but accessible only in its containing method but what is the best definition of static method? Is calling the static method without creating object of that class is the only benefit of static method? What is the accessible range for static method? What is the syntax to create and calling static method in php? Thanks

• How do I return the entire set / array using NSPredicate?

  - by Prairiedogg

  I'm building a carArray and want to filter the contents conditionally, using an NSPredicate, like so: NSPredicate *pred; switch (carType) { case FreeCar: pred = [NSPredicate predicateWithFormat:@"premium = NO"]; break; case PremiumCar: pred = [NSPredicate predicateWithFormat:@"premium = YES"]; break; default: pred = [NSPredicate predicateWithFormat:@"SOME PREDICATE THAT RETURNS EVERYTHING"]; break; } self.carArray = [aCarArrayIGotFromSomewhere filteredArrayUsingPredicate:pred]; My question is, what is the correct syntax for the value I've stubbed in as SOME PREDICATE THAT RETURNS EVERYTHING which returns all of the instances in the array / set? PS - I know the answer and will post it immediately, just sharing it for everyone's reference as an earlier search on SO did not yield the result.

• How to rewrite url to include subdirectory?

  - by Jason Roberts

  The following set of rewrite rules rewrite any urls formatted as foo.mydomain.com/bar to mydomain.com/mysubs/foo/bar.php. This all works fine except if I have a subdirectory named 'blah' in the original url such as foo.mydomain.com/blah/bar, then it will rewrite it as mydomain.com/mysubs/foo/bar (without the blah subdirectory) when what I need is the url to be rewritten as mydomain.com/mysubs/foo/blah/bar. So, what do I need to change to make this work correctly? Options +FollowSymLinks Options -Indexes RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} !www.mydomain.com$ [NC] RewriteCond %{HTTP_HOST} ^([^./]+)\.mydomain\.com$ RewriteRule !^mysubs/ mysubs/%1%{REQUEST_URI} [L] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php

• web developer editor ubuntu

  - by madphp

  Hi, I know theres hundred of questions and answers out there, but cant find one to specifically answer this. I need a web editor that will let me choose a dark themed editor. I understand gvim is one, but im not totally ready to let go of my mouse. I would like something like sublime text editor for windows, but open to other suggestions. The less bloat the best. I dont need a full IDE like eclipse, but willing to compromise, as long as the themes can easily be added. I've tried bluefish, kompozer and not happy with them. Just need a basic text editor that will highlight php syntax on a dark background.
