  • Software protection

    - by anfono
    I want to protect my software from being used without permission. I will provide it for free to the parties I authorize to use it. Anyone knows a good protection scheme against having it copied and run by unauthorized parties ? So far, I thought about introducing a key validation mechanism: periodically, the user needs to send me (web site query) a code based on which I generate a new code that app validates against. There is an initial code, and so I can track users... Thoughts ? Later edit: I changed the licensing part to avoid unfocused discussion.

  • How would I order a table by the number of matching params in the where clause of an sql statement?

    - by Eitan
    I'm writing sql to search a database by a number of parameters. How would I go about ordering the result set by the items that match the most parameters in the where clause. For example: SELECT * FROM users WHERE username = 'eitan' OR email = '[email protected]' OR company = 'eitan' Username | email | company 1) eitan | [email protected] | blah 2) eitan | [email protected] | eitan 3) eitan | [email protected] | blah should be ordered like: 2, 3, 1. Thanks. (ps the query isn't that easy, has a lot of joins and a lot of OR's in the WHERE) Eitan

    - by darren
    Hi everyone I have compiled an sqlite database that I would like to make public. I want to provide a very simple webpage that has a few form elements which are used to query the database. Does anybody know of a free hosting solution that would provide me with free web and database functionality? I am familiar with Google App Engine and that would work but I don't want to spend time using their custom storage scheme. I'm looking for something free that I can put together very quickly. Thanks for any suggestions.

  • How do I replace NOT EXISTS with JOIN?

    - by YelizavetaYR
    I've got the following query: select distinct a.id, a.name from Employee a join Dependencies b on a.id = b.eid where not exists ( select * from Dependencies d where b.id = d.id and d.name = 'Apple' ) and exists ( select * from Dependencies c where b.id = c.id and c.name = 'Orange' ); I have two tables, relatively simple. The first Employee has an id column and a name column The second table Dependencies has 3 column, an id, an eid (employee id to link) and names (apple, orange etc). the data looks like this Employee table looks like this id | name ----------- 1 | Pat 2 | Tom 3 | Rob 4 | Sam Dependencies id | eid | Name -------------------- 1 | 1 | Orange 2 | 1 | Apple 3 | 2 | Strawberry 4 | 2 | Apple 5 | 3 | Orange 6 | 3 | Banana As you can see Pat has both Orange and Apple and he needs to be excluded and it has to be via joins and i can't seem to get it to work. Ultimately the data should only return Rob

  • C# mysqlreader on same connection error

    - by dominiquel
    Hi, I must find a way to do this in C#, if possible... I must loop on my folder list (mysql table), and for each folder I instanciate I must do another query, but when I do this it says : "There is already an open DataReader associated with this Connection" and I am inside a mysqlreader loop already. Note that I have oversimplified the code just to show you, the fact is that I must do queries inside a mysqlreader loop, and it looks to be impossible as they are on the same connection? MySqlConnection cnx = new MySqlConnection(connexionString); cnx.Open(); MySqlCommand command= new MySqlCommand("SELECT * FROM folder WHERE folder_id = " + id, cnx); MySqlDataReader reader= commande.ExecuteReader(); while (reader.Read()) { this.folderList[this.folderList.Length] = new CFolder(reader.GetInt32"folder_id"), cnx); } reader.Close(); cnx.Close();

    - by peakUC
    How do I allow all users to have there username field empty without having them to enter a username when they submit the form using PHP and MySQL? Here is part my PHP and MySQL code. $username = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['username'])))); if(isset($_POST['username'])) { // Make sure the username address is available: $u = "SELECT * FROM users WHERE username = '$username' AND user_id <> '$user_id'"; $r = mysqli_query ($mysqli, $u) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($mysqli)); if (mysqli_num_rows($r) == TRUE) { // Unavailable. echo '<p class="error">Your username is unavailable!</p>'; $username = NULL; } else if(mysqli_num_rows($r) == 0) { // Available. $username = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['username'])))); } }

  • How to integrate access control with my ORM in a .net windows form application?

    - by Ying
    I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.

  • Updating rows using "in" operator in "where" clause

    - by doublep
    Hi. I stumbled upon SQL behavior I don't understand. I needed to update several rows in a table at once; started with just finding them: SELECT * FROM some_table WHERE field1 IN (SELECT ...) This returned a selection of about 60 rows. Now I was pretty confident I got the subquery right, so I modified the first part only: UPDATE some_table SET field2 = some_value WHERE field1 IN (SELECT ...) In other words, this was exactly as the first query after the WHERE. However, it resulted in 0 rows updated, whereas I would expect those 60. Note that the statement above would change field2, i.e. I verified that some_value was not present in the selected rows. The subquery was a modestly complicated SQL piece with 2 (different) tables, 1 view, joins and its own WHERE clause. In case this matters, it happened with Oracle Database 10g. So, the question is, why UPDATE didn't touch the rows returned by SELECT?

  • Djangobb problem

    - by Djero
    I've installed Djangobb app on my server (Debian, mod_python) by cloning original source. The only things I've changed is database options in settings.py. All needed components are installed - syncdb query was executed right. But, when I'm trying to enter on my forum, it returns me error: ImproperlyConfigured: Error importing middleware django_authopenid.middleware: "No module named djangobb_forum.subscription" I've checked - djangobb_forum/subscription.py exist, so I don't know what can be wrong. Maybe someone had problems like that and know how to fix it? Sorry for my english.

Can anyone help me to design the routes? ===================================================================== I update the patterns, and add my expectation at the end of each url. Any suggest on the url patterns?

  • How to send reminder notifications to subscribers for renewal from SQL Server 2005?

    - by codemonkie
    I have a table in SQL DB, namely dbo.subscribers, it contains following columns: -SubscriberID -JoinDateTime The business logic says a subscription last for 2 weeks and a reminder should be sent after 7 days from the JoinDateTime. The way that the system was designed to send reminders are via a URL call, e.g. http://xxx.xxx.xxx.xxx/renew_userid=SubscriberID/ and that can only be called from our webserver which is the only whitelisted IP machines given. Currently there is a windows service written to query the DB once a day at midnight to grab all expiring subscribers and send them reminders, however this batch approach only sends reminders to the nearest date, well, I could have set the interval down from 1 day to 1 hour such that the service can send notifications out closer to the exact JoinDateTime + 7 days requirements. I have heard a stored procedure can be written and perform task like this to a nearly real-time manner, if yes, please give me some hints on how to do it. Another question is - is SSRS bit of an overkill to perform things like this? Please advice. TIA

  • Linq To Sql Left outer join - filtering null results

    - by Harry
    I'd like to reproduce the following SQL into C# LinqToSql SELECT TOP(10) Keywords.* FROM Keywords LEFT OUTER JOIN IgnoreWords ON Keywords.WordID = IgnoreWords.ID WHERE (DomainID = 16673) AND (IgnoreWords.Name IS NULL) ORDER BY [Score] DESC The following C# Linq gives the right answer. But I can't help think I'm missing something (a better way of doing it?) var query = (from keyword in context.Keywords join ignore in context.IgnoreWords on keyword.WordID equals ignore.ID into ignored from i in ignored.DefaultIfEmpty() where i == null where keyword.DomainID == ID orderby keyword.Score descending select keyword).Take(10); the SQL produced looks something like this: SELECT TOP (10) [t0].[DomainID], [t0].[WordID], [t0].[Score], [t0].[Count] FROM [dbo].[Keywords] AS [t0] LEFT OUTER JOIN (SELECT 1 AS [test], [t1].[ID] FROM [dbo].[IgnoreWords] AS [t1]) AS [t2] ON [t0].[WordID] = [t2].[ID] WHERE ([t0].[DomainID] = 16673) AND ([t2].[test] IS NULL) ORDER BY [t0].[Score] DESC How can I get rid of this redundant inner selection? It's only slightly more expensive but every bit helps!

  • Echo mysql results in a loop?

    - by Roy D. Porter
    I am using turn.js to make a book. Every div within the 'deathnote' div becomes a new page. <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page </div> //ends book What I am doing is trying to get 3 'content' (content being a name and cause of death) divs onto 1 page, and then generate a new page. So here is what i want: <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"> //creates new page but leaves it open <div> CONTENT </div> <div> CONTENT </div> <div> CONTENT </div> </div> //ends the page </div> //ends book Seems simple enough, however the content is data from a MySQL DB, so i have to echo it in using PHP. Here is what i have so far <div id="deathnote"> <div style="background-image:url(images/coverpage.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <?php $pagecount = 0; $db = new mysqli('localhost', 'username', 'passw', 'DB'); if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error .

IT IS SIMPLE CONNECTING SCRIPT THAT I KNOW WORKS //THE METHOD I AM HAVING TROUBLE WITH IS BELOW $pagecount = 0; while($row = $result->fetch_assoc()){ //GETS THE VALUE (and makes sure it isn't nothing echo '<div style="background-image:url(images/paper.jpg);">'; //THIS OPENS A NEW PAGE while ($pagecount !== 3) { //KEEPS COUNT OF HOW MUCH CONTENT DIVS IS ON THE PAGE while($row = $result->fetch_assoc()){ //START A CONTENT DIV echo '<div class="content"><div class="name">' . $row['victim'] .

The problem resides within the while loops. Any help is greatly appreciated. Thanks in advance guys. :)

  • Loading .sql files from within PHP

    - by Josh Smeaton
    I'm creating an installation script for an application that I'm developing and need to create databases dynamically from within PHP. I've got it to create the database but now I need to load in several .sql files. I had planned to open the file and mysql_query it a line at a time - until I looked at the schema files and realised they aren't just one query per line. So, please.. how do I load an sql file from within PHP? (as phpMyAdmin does with it's import command).

  • Can't use where clause on correlated columns.

    - by Keyo
    I want to add a where clause to make sure video_count is greater than zero. Only categories which are referenced once or more in video_category.video_id should be returned. Because video_count is not a field in any table I cannot do this. Here is the query. SELECT category . * , ( SELECT COUNT( * ) FROM video_category WHERE video_category.category_id = category.category_id ) AS 'video_count' FROM category WHERE category.status = 1 AND video_count > '0' AND publish_date < NOW() ORDER BY updated DESC; Thanks for the help.

  • Using Report (Reporting Services) parameter values in ASP.NET page

    - by noup
    I have a report (Reporting Services) integrated into an ASP.NET that shows dropdownlists to select report parameter values. The dropdownlists are populated using direct database selects, though I see the report RDL files do contain the paramter values and datasets as defined in the report designer. Is it possible to obtain the report parameters "available values" in ASP.NET to populate the dropdownlists? This would avoid some code duplication. Update If the parameter doesn't use a query for available values, the following works: foreach (ValidValue value in this.ReportViewerControl.ServerReport.GetParameters()["myParameter"].ValidValues) { this.DropDownListControl.Items.Add(new ListItem(value.Label, value.Value)); } Still haven't found a way to access report datasets though...

  • HTTPS and HTTParty - Timeout and EOF

    - by ferparra
    Hi all, I'm trying to post something to an HTTPS resource, but it seems it doesn't work. My code look something like this: require 'httparty' class MyClass include HTTParty base_uri "https://mydomain.com:8085/search" basic_auth 'admin', 'changeme' format :xml def mymethod self.class.post('/job', :query => {:search => "*"}) end end As you can see, I've defined an URI with 'https' included, so it should set the use_ssl property for the Net::HTTPS library automatically. For some reason, Net::HTTP is requested, and I never get in touch with the server, so I end up with an EOF. Any clues?

  • How to get number of rows deleted from mysql in shell script

    - by simonlord
    Hi all I can't work out how to get the mysql client to return the number of rows deleted to the shell when running a delete. Does anyone know what option will enable this? Or ways around it? Here's what i'm trying, but i get no output: #!/bin/bash deleted=`mysql mydb -e "delete from mytable where insertedtime < '2010-04-01 00:00:00'"|tail -n 1` I was expecting something like this as the output from mysql: deleted 999999 Which is why i have the tail -n 1 so i only pick up the count and not the column name. When running the command by hand (mysql mydb -e "delete from mytable where insertedtime < '2010-04-01 00:00:00'") there is no output. When running the command interactively when running the mysql client i ge the following: mysql>delete from mytable where insertedtime < '2010-04-01 00:00:00'; Query OK, 0 rows affected (0.00 sec) I want to get the rows affected count into my shell variable. Any help would be most appreciated.

  • NHibernate - get List<long> representing primary keys?

    - by Nathan
    I have a situation where I definitely don't want to get the whole domain object. Basically, the entity has a primary key of long (.NET)/bigint(sql server 2005). I simply need to pass the primary key to an external system which will access the database directly - and since the list of ids could be large, I don't want to rehydrate the entire domain object just to get the Id. In linq2sql, I could accomplish this with a projection, but I am restricted to NHibernate 1.2.1.4000, which doesn't support Linq. Is there a way to accomplish this using NHibernate 1.2.1.4000? (I am open to using a named-query if that will work)

  • Google Suggest - What determines the sort order of suggested queries on google?

    - by John Himmelman
    How is this sort order determined? Is it ranked by popularity, number of results, or a mysterious google algorithm? Does there algorithm take into account the search popularity of a query (using google-trends data or something)? Edit: I found a news article dating back to when google suggest was made public in 2004. Here is an excerpt... How does it work? "Our algorithms use a wide range of information to predict the queries users are most likely to want to see. For example, Google Suggest uses data about the overall popularity of various searches to help rank the refinements it offers." Source: http://www.free-seo-news.com/newsletter138.htm

  • MySQL: Count occurrences of known (or enumerated) distinct values

    - by Eilidh
    After looking at how to count the occurrences of distinct values in a field, I am wondering how to count the occurrences of each distinct value if the distinct values are known (or enumerated). For example, if I have a simple table - TrafficLight Colour ------------ ------ 1 Red 2 Amber 3 Red 4 Red 5 Green 6 Green where one column (in this case Colour) has known (or enumerated) distinct values, how could I return the count for each colour as a separate value, rather than as an array, as in the linked example. To return an array with a count of each colour (using the same method as in the linked example), the query would be something like SELECT Colour COUNT(*) AS ColourCount FROM TrafficLights GROUP BY Colour, and return an array - Colour ColourCount ------ ----------- Red 3 Amber 1 Green 2 What I would like to do is to return the count for each Colour AS a separate total (e.g. RedCount). How can I do this?

  • Google App Engine - Dealing with concurrency issues of storing an object

    - by Spines
    My User object that I want to create and store in the datastore has an email, and a username. How do I make sure when creating my User object that another User object doesn't also have either the same email or the same username? If I just do a query to see if any other users have already used the username or the email, then there could be a race condition. UPDATE: The solution I'm currently considering is to use the MemCache to implement a locking mechanism. I would acquire 2 locks before trying to store the User object in the datastore. First a lock that locks based on email, then another that locks based on username. Since creating new User objects only happens at user registration time, and it's even rarer that two people try to use either the same username or the same email, I think it's okay to take the performance hit of locking. I'm thinking of using the MemCache locking code that is here: http://appengine-cookbook.appspot.com/recipe/mutex-using-memcache-api/ What do you guys think?

  • Some facebook friends' birthdays returning as null but I have the correct API permissions

    - by Andrei Radulescu
    I'm tring to get my friends' birthdays in my app and some of them are null. I thought that those people don't have a birthday set, but they actually do. My fql query is: SELECT uid,name,birthday_date FROM user WHERE uid IN (SELECT uid2 from friend where uid1=me()) My app has the "friends_birthday" permission set. I also tried with "birthday" instead of "birthday_date". Same result. I imagine that this happens because they opted out somehow, but I don't know how. Is there an alternate solution to actually get their birthdays from facebook? Thanks!
