  • Possible to exclude or reorder a column from `*` ?

    - by Earlz
    Is it possible to exclude a column from a select * from table statement with SQL Server? I have a need for this and this is my only option other than parsing a raw SQL string to get out the required field names (I really don't want to do that). Just to be bold. When the query is made I do not have access to the list of fields needed from the table but I do know which field I do not need. This is part of a complex multi-part query. Surely there must be some way even if it's "hackish" such as using table variables or views My other option is to reorder the columns. My problem is with ExecuteScalar SQL functions which get the first row and first column.

  • Best way in Python to determine all possible intersections in a matrix?

    - by ssweens
    So if I have a matrix (list of lists) of unique words as my column headings, document ids as my row headings, and a 0 or 1 as the values if the word exists in that particular document. What I'd like to know is how to determine all the possible combinations of words and documents where more than one word is in common with more than one document. So something like: [[Docid_3, Docid_5], ['word1', 'word17', 'word23']], [[Docid_3, Docid_9, Docid_334], ['word2', 'word7', 'word23', 'word68', 'word982']], and so on for each possible combination. Would love a solution that provides the complete set of combinations and one that yields only the combinations that are not a subset of another, so from the example, not [[Docid_3, Docid_5], ['word1', 'word17']] since it's a complete subset of the first example. I feel like there is an elegant solution that just isn't coming to mind and the beer isn't helping. Thanks.

  • Check if exists, if so, update by 1++, if not insert

    - by Scarface
    Hey guys quick question, I currently have an insert statement $query= "INSERT into new_mail VALUES ('$to1', '0')"; where fields are username, and message_number Currently what I would do to check if the entry exists, is do a select query then check the number of rows with mysql_num_rows (php). If rows==1 then I get the current message_number and set it equal to $row['message_number']++1. Then I update that entry with another query. Is there an easier way to do all this in just mysql with just one query (check if exists, if not insert, if so update message_number, increase by 1)?

  • How do you preserve the updated_at date field when saving the the database in Symfony?

    - by Failpunk
    This has to be simple... I'm trying to preserve the current date that is already stored in an updated_at field in the DB. I'm updating a single field value in the same row and then saving but I don't want it to update the updated_at field. I want to preserve the existing updated_at value. I only want to do this in one, maybe two situations so I don't need to overwrite the model for every other action in the program. I've tried this: $originalDate = $this->getUpdatedAt(); $this->setUpdatedAt($originalDate); $this->save(); This seems like it should work but still it seems to update the field.

  • Export XML with only one MySQL request ?

    - by mere-teresa
    I want to export in XML format some data from 7 tables (MySQL database), and then I want to import in another database. And I have a update or insert rule for data. I already have a SQL query retrieving all data, with JOINs on my 7 tables. But...when I try to put data in XML format, I reach a limit. My PHP loop can catch each row, but I would like to benefit from hierachical structure of the XML, and all I have are rows with the same data repeated. It is better to query once and to construct the XML tree in PHP or to query each time I want access to a lower level ?

  • ReorderListView in WPF

    - by Philipp Schmid
    I love the controls from the Bag-Of-Tricks. I am interested in modifying the ReorderListBox control to get a ReorderListView control. However, simply changing the base class from ListBox to ListView is not working. When I try to add a ReorderListView to XAML like this: <lib:ReorderListView Grid.Row="1"> <ReorderListView.View> <GridView> <GridViewColumn Header="Data1" /> </GridView> </ReorderListView.View> </lib:ReorderListView> I get an error ("The tag 'ReorderListView.View' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'.) How do I modify the ReorderListBox example to get this to work? Has anyone already succeeded in doing this?

  • .NET Regular Expressions - Shorter match

    - by Xavier
    Hi Guys, I have a question regarding .NET regular expressions and how it defines matches. I am writing: var regex = new Regex("<tr><td>1</td><td>(.+)</td><td>(.+)</td>"); if (regex.IsMatch(str)) { var groups = regex.Match(str).Groups; var matches = new List<string>(); for (int i = 1; i < groups.Count; i++) matches.Add(groups[i].Value); return matches; } What I want is get the content of the two following tags. Instead it returns: [0]: Cell 1</td><td>Cell 2</td>... [1]: Last row of the table Why is the first match taking </td> and the rest of the string instead of stopping at </td>?

  • What's the most efficient way to manage large datasets with Javascript/jQuery in IE?

    - by RenderIn
    I have a search that returns JSON, which I then transform into a HTML table in Javascript. It repeatedly calls the jQuery.append() method, once for each row. I have a modern machine, and the Firefox response time is acceptable. But in IE 8 it is unbearably slow. I decided to move the transformation from data to HTML into the server-side PHP, changing the return type from JSON to HTML. Now, rather than calling the jQuery.append() time repeatedly, I call the jQuery.html() method once with the entire table. I noticed Firefox got faster, but IE got slower. These results are anecdotal and I have not done any benchmarking, but the IE performance is very disappointing. Is there something I can do to speed up the manipulation of large amounts of data in IE or is it simply a bad idea to process very much data at once with AJAX/Javascript?

  • MS SQL Specific Tables Hanging at Queries

    - by Jonn
    I have SQL Server 2008. I run a query in a table on a database. The weirdest thing keeps happening. I run a simple select statement on the table. I know there are 62 rows in the table but it gets stuck at row 48 and goes on "querying...". Waited already for hours and it didn't move on from there. I only know of two programs, and one reporting service connecting to that particular table and one other user. Does anyone have any idea on what could be causing this and how I could trace the source of the lock on that table? As a side note, I noted that the logs only had a notice that Autogrow failed the day before I checked. Could this have something to do with it?

  • Zend_Auth_Adapter_DbTable identity not unique

    - by volf
    For authentication on a website i use Zend_Auth_Adapter_DbTable. Everything work's fine, but Zend Framework only allow unique Identitys in the table. As an identity i use the mail-address from my users. The problem is, that there are more items in the table with this mail-adress. User can delete there account and so i don't delete the whole row, i only change the status to -2 or something else. active user has the status 1. i try to use it like so: $authAdapter = new Zend_Auth_Adapter_DbTable($db, 'user', 'email', 'password', "? AND `status`='1'"); $authAdapter->setIdentity($email); $authAdapter->setCredential($password); But it doesn't work. If i delete the inactive user with the same mail-address, everything work's. Why is that?

  • Rails creating and updating 2 model records simultaneously

    - by LearnRails
    I have 2 tables product and history product table id name type price location 1 abc electronics $200 aisle1 history table id product_id status 1 1 price changed from $200 to $180 Whenever the product price or location is updated by a user by hitting the update button, 1) the changes should be automatically be reflected in the history status column without the user having to enter that manually. if the price is updated from 200 to 180 then a new history row will be created with new id and the status column will say ' price changed from $200 to $180' if the location is updated from aisle1 to aisle 2 then status displays ' loc changed from ailse1 to aisle 2' I tried to @product = Product.new(params[:product]) @history= History.new(params[:history]) if @product.save @history.new(attributes) == I am not sure of whether this approach is correct I would really appreciate if someone could tell me how the history can be automatically updated in this case.

  • Using PHP to determine if a remote file has been replaced?

    - by Rob
    I have a MySQL database with some URLs in it. One URL per row. Each URL has my script on it. What I am wanting to do, is check if the file is still there via a PHP script. Not check if it 404'd, but rather check if it has been modified or replaced. Is this possible? If so, how would it be accomplished? I was thinking making the remote file echo some string, and having the local file check the page for that string, but that seems a little inefficient and sloppy.

    - by just_azho
    Hi, folks I'm trying to achieve following by linq2sql, but not successful. I've Member and Reference tables. DB is design in such a manner that Member can have multiple (=0) References. What I want as a result of query is, list (rows) of members, where all references of the member are "collected" in one column. What I had achieved is following query, but for this one there exist a row for each Reference. var refs = (from m in db.Members join r in db.References on m.PID equals r.PID into g from o in g.DefaultIfEmpty() select new { member = m, name = (o == null ? "" : o.NameSurname) }); I feel I need to insert SelectMany somewher :) Could you please give hints on achieving the goal?

  • PHP/MySQL - an array filter for bots

    - by Mike
    Hello, I'm making a hit counter. I have a database and I store the IP and $_SERVER['HTTP_USER_AGENT']; of the visitors. Now I need to add a filter, so I can put away the hits, that are made by bots. I found out, that many bots usually keep some common words in the $_SERVER['HTTP_USER_AGENT']; , so I's like to make and array of words, that would keep the bot from displaying in the results. Here is what I have now: while($row = mysql_fetch_array($yesterday, MYSQL_ASSOC)) { <-- Here I need a code, that would run through an array and check, if it containts the keywords and if it doesn't ... just count++; -- } Also if you know any other way of detecting and removing the bots from the results, I'd be verry thankful. Cheers

  • Am I underestimating MySQL ?

    - by user281434
    Hi I'm about to implement a feature on my website that recommends content to users based on the content they already have in their library (a la Last.fm). A single table holds all the records of the content they have added, so a row might look something like: -------------------- | userid | content | -------------------- | 28 | a | -------------------- When I want to recommend some content for a user, I use a query to get all the user id's that have content a added in their library. Then, out of those user id's, I make another query that finds the next most common content among those users (fx. 'b'), and show that to the user. My problem is when I'm thinking about the big picture here. Say that eventually my site will hold something like 500.000 rows in the table, will this make the MySQL response very slow or am I underestimating MySQL here?

  • How can I insert a line at the beginning of a file with Perl's Tie::File?

    - by thebourneid
    I'm trying to insert/add a line 'COMMENT DUMMY' at the beginnig of a file as a first row if /PATTERN/ not found. I know how to do this with OPEN CLOSE function. Probably after reading the file it should look something like this: open F, ">", $fn or die "could not open file: $!"; ; print F "COMMENT DUMMY\n", @array; close F; But I have a need to implement this with the use of the Tie::File function and don't know how. use strict; use warnings; use Tie::File; my $fn = 'test.txt'; tie my @lines, 'Tie::File', $fn or die "could not tie file: $!"; untie @lines;

  • Databinding a list (in an object) to a combobox in VB.net

    - by Casey
    VB 2008 .NET 3.5 I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment. My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc. I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment." In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use. I have tried a few ideas, but none of them work properly. Any ideas on how to do this?

I'm sorry I didn't really word this very much... You might need more clarification to answer properly and I'll be glad to give any more info. Any help would be greatly appreciated, thanks!

  • Problem when exiting search in iPhone

    - by camilo
    Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!
