  • HTML stops at a PHP script made to connect to a mysql database. No errors printed.

    - by DavidR
    I'm trying to set up a login script for PHP using the tutorial on this site. The problem is that the site stops when it hits these lines, no error, no text: <?php $conn = mysql_connect('localhost', 'root', 'password') or die('error line7' . mysql_error()); mysql_select_db('mydb', $conn) or die('error line8' . mysql_error()); ?> If I take out these lines, the rest of the html runs perfectly. I've double checked my passwords and everything, nothing is working. I know very little about php and mysql other than what I've learned trying to set this up.

  • Ruby on Rails: building a model with an attribute not in the database?

    - by randombits
    I have a model that sets one of its attributes based off of a form parameter that a user submits. The model is a child resource to a parent resource Home. A hypothetical example is the following: A class Person has an age attribute. The user submits a birthdate as an HTTP POST parameter and from that, I need to derive the age of the user. So I'd do something like this: @home.people.build(:name => params[:name], :birthdate => params[:birthdate]) Rails would barf on that for obvious reasons, complaining it doesn't know what the attribute birthdate is. What's the proper way of going about this? Is it possible to use the build constructor with the supplied solution so that my foreign key relations are also setup properly? If not, what's a better way to work around this problem?

    - by Senthil
    I'm unable to get SQL and Rails to play properly when trying to find Categories that are created each day, the past 7 days. So basically I want to find each Category sorted by the day they were created for the past 7 days. I found this on stackoverflow, but it isn't finding a Category that I just created: Category.all(:conditions => ["created_at > ? AND created_at < ?", t.at_beginning_of_day, t.tomorrow.at_beginning_of_day]) Any help?

  • PHP MySQLi isn't letting me alter a table (adding a new column)

    - by asdasd
    Well thats pretty much it. This is my query: $query = 'ALTER TABLE permissions ADD '.$name.' INT NOT NULL DEFAULT \'0\''; Where $name is already checked to exist with only lower case alpha letters, and not more than 20 length. Im just starting this out with very simple names. The next 4 lines of code after that one are: if($stmt = $db -> prepare($query)) { $success = $stmt -> execute(); $stmt -> close(); if(!$success) echo 'ERROR: Unsuccessful query: ',$db->error,PHP_EOL; } And I get back, every time ERROR: Unsuccessful query: And no error message. Is there a way to get more error messages so I can see what is failing? I can add new columns through phpmyadmin, but that really doesnt help me at all. The $db is fine, i do lots of stuff before and after this one section. It is only adding new column to the table that fails. side question: prepare() rejected my query every time when i tried to make those 2 variables, the $name and the 0 value as ? ? prepared statement values. Thats why they are in the real query and not bound later. If i could change that too I would like that.

  • How to secure the communication between an MSSQL database and a c# administrative tool?

    - by citronas
    How can I secure the communication between a C# programm running locally on my computer and a MSSQL Server in a hosted environment? I have an asp.net application that is secured by SSL encryption. So using the asp.net from an open wlan connection is no problem. How can I achieve the same kind of encryption for my administrative tool? Would it be best to write a service? But how would that connection to the service be secured?

  • Should I design the application or model (database) first?

    - by YonahW
    I am getting ready to start building a new web project in my spare time to bring to fruition an idea that has been bouncing around my head for a while. I have never gotten down whether I am better off first building the model and then the consuming application or the other way around. What are the best practices? What would you build first and why? I imagine that in general the application should generally drive the model, however the application like many websites really doesn't do much without the model. For some reason I find it easier at times to think in terms of the model since the application is really just actions on the model. Is this a poor way of thinking about things? What advantages/disadvantages does each option have?

  • Python appengine Query does not work when using a variable.

    - by Lloyd
    Hi, I am trying to use a fetcher method to retrieve items from my datastore. If I use the following def getItem(item_id): q = Item.all() q.filter("itemid = ", item_id) It fails because nothing is returned. If I hard code in an item like def getItem(item_id): q = Item.all() q.filter("itemid = ", 9000) it fetches just fine, and sings merrily along. I have tried every which way to get this to work. I have used result = db.GqlQuery("SELECT * FROM Item WHERE item_id = :1 LIMIT 1", title).fetch(1) to the same effect. If I hard code in a number, works fine. I have tried setting the select statement as a local string, assembling it that way, casting the int as a string, and nothing. When I output the SELECT statement to the screen, looks fine. I can cut ans paste the output into the string, and whammo, it works. Any help would be appreciated.

  • How could I cache images that I'm pulling from a magento database through ajax?

    - by wes
    Here's script being called through ajax: <?php require_once '../app/Mage.php'; umask(0); /* not Mage::run(); */ Mage::app('default'); $cat_id = ($_POST['cat_id']) ? $_POST['cat_id'] : NULL; try { $category = new Mage_Catalog_Model_Category(); $category->load($cat_id); $collection = $category->getProductCollection(); $output = '<ul>'; foreach ($collection as $product) { $cProduct = Mage::getModel('catalog/product'); $cProduct->load($product->getId()); $output .= '<li><img id="'.$product->getId().'" src="' . (string)Mage::helper('catalog/image')->init($cProduct, 'small_image')->resize(75) . '" class="thumb" /></li>'; } $output .= '</ul>'; echo $output; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } I'm just passing in the Category ID, which I've tacked onto the navigation links, then doing some work to eventually just pass back all product images in that category. I'm using this on a drag and drop build-a-bracelet type of application, and the amount of images returned is sometimes in the 500s. So it get's pretty held up during transmission, sometimes 10 seconds or so. I know I'd do good by caching them some way, just not sure how to go about it. Any help is much appreciated. Thanks. -Wes

  • SQL indexes for "not equal" searches

    - by bortzmeyer
    The SQL index allows to find quickly a string which matches my query. Now, I have to search in a big table the strings which do not match. Of course, the normal index does not help and I have to do a slow sequential scan: essais=> \d phone_idx Index "public.phone_idx" Column | Type --------+------ phone | text btree, for table "public.phonespersons" essais=> EXPLAIN SELECT person FROM PhonesPersons WHERE phone = '+33 1234567'; QUERY PLAN ------------------------------------------------------------------------------- Index Scan using phone_idx on phonespersons (cost=0.00..8.41 rows=1 width=4) Index Cond: (phone = '+33 1234567'::text) (2 rows) essais=> EXPLAIN SELECT person FROM PhonesPersons WHERE phone != '+33 1234567'; QUERY PLAN ---------------------------------------------------------------------- Seq Scan on phonespersons (cost=0.00..18621.00 rows=999999 width=4) Filter: (phone <> '+33 1234567'::text) (2 rows) I understand (see Mark Byers' very good explanations) that PostgreSQL can decide not to use an index when it sees that a sequential scan would be faster (for instance if almost all the tuples match). But, here, "not equal" searches are really slower. Any way to make these "is not equal to" searches faster? Here is another example, to address Mark Byers' excellent remarks. The index is used for the '=' query (which returns the vast majority of tuples) but not for the '!=' query: essais=> EXPLAIN ANALYZE SELECT person FROM EmailsPersons WHERE tld(email) = 'fr'; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------------------ Index Scan using tld_idx on emailspersons (cost=0.25..4010.79 rows=97033 width=4) (actual time=0.137..261.123 rows=97110 loops=1) Index Cond: (tld(email) = 'fr'::text) Total runtime: 444.800 ms (3 rows) essais=> EXPLAIN ANALYZE SELECT person FROM EmailsPersons WHERE tld(email) != 'fr'; QUERY PLAN -------------------------------------------------------------------------------------------------------------------- Seq Scan on emailspersons (cost=0.00..27129.00 rows=2967 width=4) (actual time=1.004..1031.224 rows=2890 loops=1) Filter: (tld(email) <> 'fr'::text) Total runtime: 1037.278 ms (3 rows) DBMS is PostgreSQL 8.3 (but I can upgrade to 8.4).

  • My Linq to Sql Insert code seems to work fine but I don't get a record in the database

  • Can in-memory SQLite databases be used concurrently?

    - by Kent Boogaart
    In order to prevent a SQLite in-memory database from being cleaned up, one must use the same connection to access the database. However, using the same connection causes SQLite to synchronize access to the database. Thus, if I have many threads performing reads against an in-memory database, it is slower on a multi-core machine than the exact same code running against a file-backed database. Is there any way to get the best of both worlds? That is, an in-memory database that permits multiple, concurrent calls to the database?

  • How do I query delegation properties of an active directory user account?

    - by Mark J Miller
    I am writing a utility to audit the configuration of a WCF service. In order to properly pass credentials from the client, thru the WCF service back to the SQL back end the domain account used to run the service must be configured in Active Directory with the setting "Trust this user for delegation" (Properties - "Delegation" tab). Using C#, how do I access the settings on this tab in Active Directory. I've spent the last 5 hours trying to track this down on the web and can't seem to find it. Here's what I've done so far: using (Domain domain = Domain.GetCurrentDomain()) { Console.WriteLine(domain.Name); // get domain "dev" from MSSQLSERVER service account DirectoryEntry ouDn = new DirectoryEntry("LDAP://CN=Users,dc=dev,dc=mydomain,dc=lcl"); DirectorySearcher search = new DirectorySearcher(ouDn); // get sAMAccountName "dev.services" from MSSQLSERVER service account search.Filter = "(sAMAccountName=dev.services)"; search.PropertiesToLoad.Add("displayName"); search.PropertiesToLoad.Add("userAccountControl"); SearchResult result = search.FindOne(); if (result != null) { Console.WriteLine(result.Properties["displayName"][0]); DirectoryEntry entry = result.GetDirectoryEntry(); int userAccountControlFlags = (int)entry.Properties["userAccountControl"].Value; if ((userAccountControlFlags & (int)UserAccountControl.TRUSTED_FOR_DELEGATION) == (int)UserAccountControl.TRUSTED_FOR_DELEGATION) Console.WriteLine("TRUSTED_FOR_DELEGATION"); else if ((userAccountControlFlags & (int)UserAccountControl.TRUSTED_TO_AUTH_FOR_DELEGATION) == (int)UserAccountControl.TRUSTED_TO_AUTH_FOR_DELEGATION) Console.WriteLine("TRUSTED_TO_AUTH_FOR_DELEGATION"); else if ((userAccountControlFlags & (int)UserAccountControl.NOT_DELEGATED) == (int)UserAccountControl.NOT_DELEGATED) Console.WriteLine("NOT_DELEGATED"); foreach (PropertyValueCollection pvc in entry.Properties) { Console.WriteLine(pvc.PropertyName); for (int i = 0; i < pvc.Count; i++) { Console.WriteLine("\t{0}", pvc[i]); } } } } The "userAccountControl" does not seem to be the correct property. I think it is tied to the "Account Options" section on the "Account" tab, which is not what we're looking for but this is the closest I've gotten so far. The justification for all this is: We do not have permission to setup the service in QA or in Production, so along with our written instructions (which are notoriously only followed in partial) I am creating a tool that will audit the setup (WCF and SQL) to determine if the setup is correct. This will allow the person deploying the service to run this utility and verify everything is setup correctly - saving us hours of headaches and reducing downtime during deployment.
