• MySQL SELECT results from 1 table, but exclude results depending on another table?

  - by Brandon

  Hey, What SQL query would I have to use if I want to get the results from a table 'messages' but exclude rows that have the value in 'messages_view' where field messages.message=messages_view.id AND messages.deleted=1 AND messages_view.user=$somephpvariable In more laymen terms, I have a messages table with each message denoted by an 'id' as well as a messages_view table connected with a 'message' field. I want to get the rows in message that are not deleted (comes from messages_view) for a specific 'user'. 'deleted'=1 when the message is deleted. Here is my current SQL Query that just gets the values out of : SELECT * FROM messages WHERE ((m_to=$user_id) OR (m_to=0 AND (m_to_state='' OR m_to_state='$state') AND (m_to_city='' OR m_to_city='$city'))) Here is the layout of my tables: table: messages ---------------------------- id (INT) (auto increment) m_from (INT) <-- Represents a user id (0 = site admin) m_to (INT) <-- Represents a user id (0 = all users) m_to_state (VARCHAR) m_to_city (VARCHAR) table: messages_view ---------------------------- message (INT) <-- Corresponds to messages.id above user (INT) <-- Represents a user id deleted (INT) <-- 1 = deleted

• two HashMap iteration

  - by user431276

  I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

• Html encoding in MVC input

  - by fearofawhackplanet

  I'm working through NerdDinner and I'm a bit confused about the following section... First they've added a form for creating a new dinner, with a bunch of textboxes delcared like: <%= Html.TextArea("Description") %> They then show two ways of binding form input to the model: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create() { Dinner dinner = new Dinner(); UpdateModel(dinner); ... } or: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Dinner dinner) { ... } Ok, great, that all looks really easy so far. Then a bit later on they say: It is important to always be paranoid about security when accepting any user input, and this is also true when binding objects to form input. You should be careful to always HTML encode any user-entered values to avoid HTML and JavaScript injection attacks Huh? MVC is managing the data binding for us. Where/how are you supposed to do the HTML encoding?

• Variable scope in javascript

  - by Rich Bradshaw

  This is a simple question, but I can't work it out. The specifics aren't important, but here's the gist. I have some code like this: var lat = 0; var lon = 0; if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { lat = position.coords.latitude; lon = position.coords.longitude; }); } What I think it's doing is: Set lat and lon to 0 If the browser has geolocation, overwrite those variables with real values However, at the end of that chunk, lat and lon are still 0. I've tried adding vars, passing lat and lon to the function etc but with no success... How do I make this work?

• ASP.NET MVC - How to Preserve ModelState Errors Across RedirectToAction?

  - by RPM1984

  Hi Guys, I have the following two action methods (simplified for question): [HttpGet] public ActionResult Create(string uniqueUri) { // get some stuff based on uniqueuri, set in ViewData. return View(); } [HttpPost] public ActionResult Create(Review review) { // validate review if (validatedOk) { return RedirectToAction("Details", new { postId = review.PostId}); } else { ModelState.AddModelError("ReviewErrors", "some error occured"); return RedirectToAction("Create", new { uniqueUri = Request.RequestContext.RouteData.Values["uniqueUri"]}); } } So, if the validation passes, i redirect to another page (confirmation). If an error occurs, i need to display the same page with the error. If i do return View(), the error is displayed, but if i do return RedirectToAction (as above), it loses the Model errors. I'm not surprised by the issue, just wondering how you guys handle this? I could of course just return the same View instead of the redirect, but i have logic in the "Create" method which populates the view data, which i'd have to duplicate. Any suggestions?

• Problem saving Text file in database using Hibernate

  - by Marquinio

  I'm having a problem saving large text files to MySQL database. If the text file size is around 5KB it successfully saves. If file is 148KB then I get this error from Hibernate: org.hibernate.exception.DataException: Could not execute JDBC batch update These is the SQL shows by Hibernate: Hibernate: insert into file_table (ID,FILE) values (?, ?) And in my hibernate file I'm using java.sql.Blob to store the file. Anyone knows why it fails to save a file size of 148KB but if I open that same file, cut it down to around 5KB, it will successfully save it? I thought the default limit was I think 2GB? This is weird. Thanks.

• LINQ Equivalent query

  - by GilliVilla

  I have a List<string> List<string> students; students.Add("123Rob"); students.Add("234Schulz"); and a Dictionary<string,string> Dictionary<string, string> courses = new Dictionary<string, string>(); courses .Add("Rob", "Chemistry"); courses .Add("Bob", "Math"); courses .Add("Holly", "Physics"); courses .Add("Schulz", "Botany"); My objective now is to get a List with the values - {Chemistry,Botany} . In other words, I am trying to get the LINQ equivalent of select value from [courses] where [courses].key in ( select [courses].key from courses,students where [students].id LIKE '%courses.key%' ) How should the LINQ query be framed?

• Preprocessor Conditionals

  - by Mike

  I was wondering if it would be possible to have a define which changes values at some point in the code be used in a conditional. Basically something like this: //////////////////////////////////////////// SomeFile.cpp #define SHUTDOWN false while(window->isOpen()) { if(SHUTDOWN) window->close(); // Rest of the main loop } //////////////////////////////////////////// SomeOtherFile.cpp if(Escape.isPressed()) { #undef SHUTDOWN #define SHUTDOWN true } Thus causing the app to close. If it's not, would having a function like RenderWindow* getWindow() { return window; } and then calling if(Escape.isPressed()) getWindow()->close(); The best way to do it? I'd rather not go that route because the classes that are calling the key event are members of the class controlling the main loop and the window, so I'd have to set pointers to the containing class in the smaller classes to call getWindow() and it just seems like a more complicated method. But if I can't do it with preprocessor directives I'll just have to use pointers to the parent class.

• Is there any way to do a WER "Request Additional Files" for the windows temp directory?

  - by Jason Mathison

  My company has had numerous crashes reported to windows error reporting due to what looks like an install problem. The logs for our installs are typically in the windows\temp directory. I would like to include the install log file as a "Request Additional Files" entry, however there doesn't seem to be any way to get to a subdirectory of the list of environmental Variables that are provided. The windows temp directory is not in the list of values that you can work from, so I am stuck. In general, I don't understand how it is possible to get at almost anything of use via the "Request Additional Files". For example, the %programfiles% directory shouldn't contain any useful files, they should be in a subdirectory for your product. What am I missing?

• How to pass or display mySQL data based on subscription or billing

  - by spm

  I want to build a PHP based site where, the user can view data based on the types of data they've paid for. Allow me to use something simple for an example. Let's say historical data for basketball was not readily available but could be purchased. Simple information such as the Winner, Loser, Final score and date are all stored in a mySQL table. What would be involved so that, when the user logs in, they can only see the historical data they have paid for. My theories so far about the architecture: I imagined a mySQL table storing True or False values for all historical game data they have paid for. Based on this, a 'data chart' object enables the user to view all data within their mySQL row which has a value of 'true.' Follow ups: Assuming I am correct, what methods are popular or practical for this type of service.

• Remove adjacent identical elements in a Ruby Array?

  - by Mike Woodhouse

  Ruby 1.8.6 I have an array containing numerical values. I want to reduce it such that sequences of the same value are reduced to a single instance of that value. So I want a = [1, 1, 1, 2, 2, 3, 3, 3, 3, 2, 2, 2, 3, 3, 3] to reduce to [1, 2, 3, 2, 3] As you can see, Array#uniq won't work in this case. I have the following, which works: (a.size - 1).downto(1) { |i| a[i] = nil if a[i - 1] == a[i] } Can anyone come up with something less ugly?

• How to use Zend_Cache Identifier ?

  - by ArneRie

  Hi Folks, i think iam getting crazy, iam trying to implement Zend_Cache to cache my database query. I know how it works and how to configure. But i cant find a good way to set the Identifier for the cache entrys. I have an method wich search for records in my database (based on an array with search values). /** * Find Record(s) * Returns one record, or array with objects * * @param array $search Search columns => value * @param integer $limit Limit results * @return array One record , or array with objects */ public function find(array $search, $limit = null) { $identifier = 'NoIdea'; if (!($data = $this->_cache->load($identifier))) { // fetch // save to cache with $identifier.. } But what kind of identifier can use in this situation?

• I'm looking for a constraint to prevent the insert of an empty string in MySQL

  - by Marga Keuvelaar

  Ok, in this question I learned how to prevent the insert of a NULL value. But, unfortunately, an empty string is being inserted anyway. Apart from preventing this on the PHP side, I'd like to use something like a database constraint to prevent this. Of course a check on the application side is necessary, but I'd like it to be on both sides. I am taught that whatever application is talking to your database, it should not be able to insert basically wrong data in it. So... CREATE TABLE IF NOT EXISTS tblFoo ( foo_id int(11) NOT NULL AUTO_INCREMENT, foo_test varchar(50) NOT NULL, PRIMARY KEY (foo_id) ); Would still allow me to do this insert: INSERT INTO tblFoo (foo_test) VALUES (''); Which I would like to prevent.

• String Functions in IIS Url Rewritting Module

  - by Nariman

  The IIS URL Rewrite Module ships with 3 built-in functions: * ToLower - returns the input string converted to lower case. * UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters). * UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern. The functions can be invoked by using the following syntax: {function_name:any_string} The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition?

• building objects from xml file at runtime and intializing, in one pass?

  - by KaluSingh Gabbar

  I have to parse the XML file and build objects representation based on that, now once I get all these data I create entries in various database for these data objects. I have to do second pass over that for value as in the first pass all I could do is build the assets in various databases. and in second pass I get the values for all the data and put it in the database. I have a feeling that this can be done in a single pass but I just want to see what are your opinions. As I am just a student who started with professional work, experienced ppl please help. Can someone who have ideas or done similar work, please provide some light on the topic so that I can think over the possibility of the work and get the prototype going based on your suggestion. Thanks a lot for your precious time, I honestly appreciate it.

• Better way to write this Java code?

  public void handleParsedCommand(String[] commandArr) { if(commandArr[0].equalsIgnoreCase("message")) { int target = Integer.parseInt(commandArr[1]); String message = commandArr[2]; MachatServer.sendMessage(target, this.conId, message); } else if(commandArr[0].equalsIgnoreCase("quit")) { // Tell the server to disconnect us.

Each message contains the type in commandArr[0] and the parameters in the rest of commandArr[]. However, this current code, while working seems very unelegant. Is there a better way to handle it? (To the best of my knowledge, String values can't be used in switch statements, and even then, a switch statement would only be a small improvement.

• erlang io:format, and a hanging web application

  - by williamstw

  While I'm learning a new language, I'll typically put lots of silly println's to see what values are where at specific times. It usually suffices because the languages typically have available a tostring equivalent. In trying that same approach with erlang, my webapp just "hangs" when there's a value attempted to be printed that's not a list. This happens when variable being printed is a tuple instead of a list. There's no error, exception, nothing... just doesn't respond. Now, I'm muddling through by being careful about what I'm writing out and as I learn more, things are getting better. But I wonder, is there a way to more reliably to [blindly] print a value to stdout? Thanks, --tim

• Pass dynamic value in URL with CakePHP

  - by Renato Dinhani Conceição

  I have the following method that performs an Ajax request passing some dynamic value obtained from a select input. It works fine, but the dynamic value is passed as parameter in the URL, something like states/listCities/?big_string_of_serialized_parameter . $this->Js->event( 'change', $this->Js->request( array( #url 'controller' => 'states', 'action' => 'listCities'), array( # ajax options that generates the serialized parameter 'update' => '#DealerCityId', 'data' => '$("#DealerStateId").serialize()', 'dataExpression' => true ) ) ); I'm trying to do this in a more friendly URL way, something like states/listCities/2. It's possible in CakePHP to generate a friendly URL like this with dynamic value from a input or is only possible passing the dynamic values as parameters?

• Validate a date range within MySQL query

  - by fishcracker

  (This question may seem easy or kind of noobish, by that I pardon my ignorance.) I used PDO query to use SELECT then fetch some values, it comes to a point that I need to fetch only some entries that within its start date and end date. My database +----------+-----------------+----------------------+--------------------+ | id (INT) | title (VARCHAR) | start_date (VARCHAR) | end_date (VARCHAR) | +----------+-----------------+----------------------+--------------------+ | 1 | buddy | 2012-11-26 | 2012-11-30 | | 2 | metro | 2012-12-05 | 2012-12-20 | | 3 | justin | 2012-11-28 | 2012-12-01 | +----------+-----------------+----------------------+--------------------+ My query is as follows: $query = "SELECT title, start_date, end_date FROM debts WHERE start_date >= CURDATE() AND end_date >= CURDATE()"; What I want to achieve is whenever the start_date is today or greater but not exceeding the end_date it will be valid. This will return the row for id 1, however if I change the start_date to 2012-11-25, it will fail due to the first condition on AND. I'm really confuse on this since I am new to this, is there any built-in function to handle this kind of situation?
