• Editable, growable DataGrid that retains values on postback and updates underlying DataTable

  - by jlstrecker

  I'm trying to create an ASP.NET/C# page that allows the user to edit a table of data, add rows to it, and save the data back to the database. For the table of data, I'm using a DataGrid whose cells contain TextBoxes or CheckBoxes. I have a button for adding rows (which works) and a button for saving the data. However, I'm quite stuck on two things: The TextBoxes and CheckBoxes should retain their values on postback. So if the user edits a TextBox and clicks the button to add more rows, the edits should be retained when the page reloads. However, the edits should not be saved to the database at this point. When the user clicks the save button, or anytime before, the DataTable underlying the DataGrid needs to be updated with the values of the TextBoxes and CheckBoxes so that the DataTable can be sent to the database. I have a method that does this, but I can't figure out when to call it. Any help getting this to work, or suggestions of alternative user interfaces that would behave similarly, would be appreciated.

• Get the first and last posts in a thread

  - by Grampa

  I am trying to code a forum website and I want to display a list of threads. Each thread should be accompanied by info about the first post (the "head" of the thread) as well as the last. My current database structure is the following: threads table: id - int, PK, not NULL, auto-increment name - varchar(255) posts table: id - int, PK, not NULL, auto-increment thread_id - FK for threads The tables have other fields as well, but they are not relevant for the query. I am interested in querying threads and somehow JOINing with posts so that I obtain both the first and last post for each thread in a single query (with no subqueries). So far I am able to do it using multiple queries, and I have defined the first post as being: SELECT * FROM threads t LEFT JOIN posts p ON t.id = p.thread_id ORDER BY p.id LIMIT 0, 1 The last post is pretty much the same except for ORDER BY id DESC. Now, I could select multiple threads with their first or last posts, by doing: SELECT * FROM threads t LEFT JOIN posts p ON t.id = p.thread_id ORDER BY p.id GROUP BY t.id But of course I can't get both at once, since I would need to sort both ASC and DESC at the same time. What is the solution here? Is it even possible to use a single query? Is there any way I could change the structure of my tables to facilitate this? If this is not doable, then what tips could you give me to improve the query performance in this particular situation?

• Map inheritance from generic class in Linq To SQL

  - by Ksenia Mukhortova

  Hi everyone, I'm trying to map my inheritance hierarchy to DB using Linq to SQL: Inheritance is like this, classes are POCO, without any LINQ to SQL attributes: public interface IStage { ... } public abstract class SimpleStage<T> : IStage where T : Process { ... } public class ConcreteStage : SimpleStage<ConcreteProcess> { ... } Here is the mapping: <Database Name="NNN" xmlns="http://schemas.microsoft.com/linqtosql/mapping/2007"> <Table Name="dbo.Stage" Member="Stage"> <Type Name="BusinessLogic.Domain.IStage"> <Column Name="ID" Member="ID" DbType="Int NOT NULL IDENTITY" IsPrimaryKey="true" IsDbGenerated="true" AutoSync="OnInsert" /> <Column Name="StageType" Member="StageType" IsDiscriminator="true" /> <Type Name="BusinessLogic.Domain.SimpleStage" IsInheritanceDefault="true"> <Type Name="BusinessLogic.Domain.ConcreteStage" IsInheritanceDefault="true" InheritanceCode="1"/> </Type> </Type> </Table> </Database> In the runtime I get error: System.InvalidOperationException was unhandled Message="Mapping Problem: Cannot find runtime type for type mapping 'BusinessLogic.Domain.SimpleStage'." Neither specifying SimpleStage, nor SimpleStage<T> in mapping file helps - runtime keeps producing different types of errors. DC is created like this: StreamReader sr = new StreamReader(@"MappingFile.map"); XmlMappingSource mapping = XmlMappingSource.FromStream(sr.BaseStream); DataContext dc = new DataContext(@"connection string", mapping); If Linq to SQL doesn't support this, could you, please, advise some other ORM, which does. Thanks in advance, Regards! Ksenia

• Complex sorting on MySQL database

  - by ChrisR

  I'm facing the following situation. We've got an CMS with an entity with translations. These translations are stored in a different table with a one-to-many relationship. For example newsarticles and newsarticle_translations. The amount of available languages is dynamically determined by the same CMS. When entering a new newsarticle the editor is required to enter at least one translation, which one of the available languages he chooses is up to him. In the newsarticle overview in our CMS we would like to show a column with the (translated) article title, but since none of the languages are mandatory (one of them is mandatory but i don't know which one) i don't really know how to construct my mysql query to select a title for each newsarticle, regardless of the entered language. And to make it all a little harder, our manager asked for the possibilty to also be able to sort on title, so fetching the translations in a separate query is ruled out as far as i know. Anyone has an idea on how to solve this in the most efficient way? Here are my table schema's it it might help > desc news; +-----------------+----------------+------+-----+-------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------------+----------------+------+-----+-------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | category_id | int(1) | YES | | NULL | | | created | timestamp | NO | | CURRENT_TIMESTAMP | | | user_id | int(10) | YES | | NULL | | +-----------------+----------------+------+-----+-------------------+----------------+ > desc news_translations; +-----------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------------+------------------+------+-----+---------+----------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | enabled | tinyint(1) | NO | | 0 | | | news_id | int(1) unsigned | NO | | NULL | | | title | varchar(255) | NO | | | | | summary | text | YES | | NULL | | | body | text | NO | | NULL | | | language | varchar(2) | NO | | NULL | | +-----------------+------------------+------+-----+---------+----------------+ PS: i've though about subqueries and coalesce() solutions but those seem rather dirty tricks, wondering if something better is know that i'm not thinking of?

• Pagination in Joomla!

  I'm a bit new to Joomla! and I'm building my new web site using Joomla! 1.5.8 with a template bought from RocketTheme. The long article in question is a gallery of photos, and I wanted to create a horizontal pagination nav-bar in the footer of the gallery, I just clicked pagebreak where I wanted to paginate in my article in the WYSIWYG editor and thought that it's actually all I have to do. What I got was ugly; a vertically directed navigation bar placed in the top right side of my gallery with the links to each part of the article, the all without the minimum styling. And as I see it's a table! Why not outputting a list instead of a table! (Well this is not actually my concern right now). I can understand CSS and html, but I'm not really a PHP guy, so I don't understand how to use pagination.php or pagenavigation.php! Do I have to customize one of them to have my nav-bar? What I have to do to get that horizontal nav-bar? Really thanks in advance. Wassim

• Can using Chronic impair your sense of time?

  - by Trip

  Haha.. I'm using Chronic to parse the time users add in the Calendar. Where the code works and implements the right time, the end result is that, IF a user adds a time, then it has no date, and because it has no date, it will not show in results. Any ideas? def set_dates unless self.natural_date.blank? || Chronic.parse(self.natural_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_date) self.date = nil self.time = Chronic.parse(self.natural_date) else self.date = Chronic.parse(self.natural_date).to_date self.time = nil end end unless self.natural_end_date.blank? || Chronic.parse(self.natural_end_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_end_date) self.end_date = nil self.end_time = Chronic.parse(self.natural_end_date) else self.end_date = Chronic.parse(self.natural_end_date).to_date self.end_time = nil end end end Edit: Here is the time_provided? method: def time_provided?(natural_date_string) date_span = Chronic.parse(natural_date_string, :guess => false) (date_span.last - date_span.first).to_i == 1 end

• mySQL select and group by values

  - by Foo

  I'd like to count and group rows by specific values. This seems fairly simple, but I can't seem to do it. I have a table set up similar to this: Table: Ratings id pID uID rating 1 1 2 7 2 1 7 7 3 1 5 4 4 1 1 1 id is the primary key, piD and uID are foreign-keys. Rating contains values between 1 and 10, and only between 1 and 10. I want to run some statistics and count the number of ratings with a certain value. In the example above, two have left a rating of 7. So I wrote the following query: SELECT COUNT(*) AS 'count' , 'rating' FROM 'ratings' WHERE pID= '1' GROUP BY `rating` ORDER BY `rating` Which yields the nice result as: count ratings 1 1 1 4 2 7 I'd like to get the mySQL query to include values between 1 and 10 as well. For example: Desired Result count ratings 1 1 0 2 0 3 1 4 0 5 0 6 2 7 0 8 0 9 0 10 Unfortunately, I'm relatively new to SQL and I've been reading through everything I could get my hands on for the past hour, but I can't get it to work. I've been leaning along the lines of a some type of JOIN. If anyone can point me in the right direction, it'd be appreciated. Thanks.

• MySQL query paralyzes site

  - by nute

  Once in a while, at random intervals, our website gets completely paralyzed. Looking at SHOW FULL PROCESSLIST;, I've noticed that when this happens, there is a specific query that is "Copying to tmp table" for a loooong time (sometimes 350 seconds), and almost all the other queries are "Locked". The part I don't understand is that 90% of the time, this query runs fine. I see it going through in the process list and it finishes pretty quickly most of the time. This query is being called by an ajax call on our homepage to display product recommendations based your browsing history (a la amazon). Just sometimes, randomly (but too often), it gets stuck at "copying to tmp table". Here is a caught instance of the query that was up 109 seconds when I looked: SELECT DISTINCT product_product.id, product_product.name, product_product.retailprice, product_product.imageurl, product_product.thumbnailurl, product_product.msrp FROM product_product, product_xref, product_viewhistory WHERE ( (product_viewhistory.productId = product_xref.product_id_1 AND product_xref.product_id_2 = product_product.id) OR (product_viewhistory.productId = product_xref.product_id_2 AND product_xref.product_id_1 = product_product.id) ) AND product_product.outofstock='N' AND product_viewhistory.cookieId = '188af1efad392c2adf82' AND product_viewhistory.productId IN (24976, 25873, 26067, 26073, 44949, 16209, 70528, 69784, 75171, 75172) ORDER BY product_xref.hits DESC LIMIT 10 Of course the "cookieId" and the list of "productId" changes dynamically depending on the request. I use php with PDO.

• ruby on rails implement search with auto complete

  - by user429400

  I've implemented a search box that searches the "Illnesses" table and the "symptoms" table in my DB. Now I want to add auto-complete to the search box. I've created a new controller called "auto_complete_controller" which returns the auto complete data. I'm just not sure how to combine the search functionality and the auto complete functionality: I want the "index" action in my search controller to return the search results, and the "index" action in my auto_complete controller to return the auto_complete data. Please guide me how to fix my html syntax and what to write in the js.coffee file. I'm using rails 3.x with the jquery UI for auto-complete, I prefer a server side solution, and this is my current code: main_page/index.html.erb: <p> <b>Syptoms / Illnesses</b> <%= form_tag search_path, :method => 'get' do %> <p> <%= text_field_tag :search, params[:search] %> <br/> <%= submit_tag "Search", :name => nil %> </p> <% end %> </p> auto_complete_controller.rb: class AutoCompleteController < ApplicationController def index @results = Illness.order(:name).where("name like ?", "%#{params[:term]}%") + Symptom.order(:name).where("name like ?", "%#{params[:term]}%") render json: @results.map(&:name) end end search_controller.rb: class SearchController < ApplicationController def index @results = Illness.search(params[:search]) + Symptom.search(params[:search]) respond_to do |format| format.html # index.html.erb format.json { render json: @results } end end end Thanks, Li

• Stable/repeatable random sort (MySQL, Rails)

  - by Matt Rogish

  I'd like to paginate through a randomly sorted list of ActiveRecord models (rows from MySQL database). However, this randomization needs to persist on a per-session basis, so that other people that visit the website also receive a random, paginate-able list of records. Let's say there are enough entities (tens of thousands) that storing the randomly sorted ID values in either the session or a cookie is too large, so I must temporarily persist it in some other way (MySQL, file, etc.). Initially I thought I could create a function based on the session ID and the page ID (returning the object IDs for that page) however since the object ID values in MySQL are not sequential (there are gaps), that seemed to fall apart as I was poking at it. The nice thing is that it would require no/minimal storage but the downsides are that it is likely pretty complex to implement and probably CPU intensive. My feeling is I should create an intersection table, something like: random_sorts( sort_id, created_at, user_id NULL if guest) random_sort_items( sort_id, item_id, position ) And then simply store the 'sort_id' in the session. Then, I can paginate the random_sorts WHERE sort_id = n ORDER BY position LIMIT... as usual. Of course, I'd have to put some sort of a reaper in there to remove them after some period of inactivity (based on random_sorts.created_at). Unfortunately, I'd have to invalidate the sort as new objects were created (and/or old objects being removed, although deletion is very rare). And, as load increases the size/performance of this table (even properly indexed) drops. It seems like this ought to be a solved problem but I can't find any rails plugins that do this... Any ideas? Thanks!!

• How to remove empty tables from a MySQL backup file.

  - by user280708

  I have multiple large MySQL backup files all from different DBs and having different schemas. I want to load the backups into our EDW but I don't want to load the empty tables. Right now I'm cutting out the empty tables using AWK on the backup files, but I'm wondering if there's a better way to do this. If anyone is interested, this is my AWK script: EDIT: I noticed today that this script has some problems, please beware if you want to actually try to use it. Your output may be WRONG... I will post my changes as I make them. # File: remove_empty_tables.awk # Copyright (c) Northwestern University, 2010 # http://edw.northwestern.edu /^--$/ { i = 0; line[++i] = $0; getline if ($0 ~ /-- Definition/) { inserts = 0; while ($0 !~ / ALTER TABLE .* ENABLE KEYS /) { # If we already have an insert: if (inserts > 0) print else { # If we found an INSERT statement, the table is NOT empty: if ($0 ~ /^INSERT /) { ++inserts # Dump the lines before the INSERT and then the INSERT: for (j = 1; j <= i; ++j) print line[j] i = 0 print $0 } # Otherwise we may yet find an insert, so save the line: else line[++i] = $0 } getline # go to the next line } line[++i] = $0; getline line[++i] = $0; getline if (inserts > 0) { for (j = 1; j <= i; ++j) print line[j] print $0 } next } else { print "--" } } { print }

• Is it possible to load an entire SQL Server CE database into RAM?

  - by DanM

  I'm using LinqToSql to query a small SQL Server CE database. I've noticed that any operations involving sub-properties are disappointingly slow. For example, if I have a Customer table that is referenced by an Order table via a foreign key, LinqToSql will automatically create an EntitySet<Order> property. This is a nice convenience, allowing me to do things like Customer.Order.Where(o => o.ProductName = "Stopwatch"), but for some reason, SQL Server CE hangs up pretty bad when I try to do stuff like this. One of my queries, which isn't really that complicated takes 3-4 seconds to complete. I can get the speed up to acceptable, even fast, if I just grab the two tables individually and convert them to List<Customer> and List<Order>, then join then manually with my own query, but this is throwing out a lot of the appeal of LinqToSql. So, I'm wondering if I can somehow get the whole database into RAM and just query that way, then occasionally save it. Is this possible? How? If not, is there anything else I can do to boost the performance? Note: My database in its initial state is about 250K and I don't expect it to grow to more than 1-2Mb. So, loading the data into RAM certainly wouldn't be a problem from a memory point of view.

• Why does Java return a date in GMT-4.5 when choosing Co-ordinated Universal Time time zone in Window

  - by Simon Nickerson

  We have seen a strange issue on some Windows XP machines involving the "Co-ordinated Universal Time" time zone. Not all Windows XP machines seem to have it, but on those that do, the following simple Java program public class TimeTest { public static void main(String[] args) { System.out.println(java.util.TimeZone.getDefault()); System.out.println(new java.util.Date()); } } on JDK 1.6.0_06 prints: sun.util.calendar.ZoneInfo[id="America/Caracas",offset=-16200000,dstSavings=0,useDaylight=false,transitions=5,lastRule=null] Fri Nov 13 05:34:14 VET 2009 (i.e. 4 and a half hours behind GMT). I should add that I am based in London, and have never been to South America. :-) My questions are: Where does Java get this time zone from? I thought Co-ordinated Universal Time was supposed to be the new name for GMT. Why do some Windows machines have this time zone but not others?

• add gtk.widget in a gnome Applet

  - by dominos

  Hi, I have a question : I write a little gnome applet, and when we click on a button i want to add a gtk.widget under the "gnome-panel" like the calendar of the clock-applet. But I don't know how to do this. It's my code : listButton = gtk.Button(_("lastest")) self.listTwitt = gtk.TreeView() mainLayout = gtk.VBox() mainLayout.pack_start(listButton) mainLayout.pack_start(self.listTwitt) self.applet.add(mainLayout) With this code, when i click on the button, the list shows up in the gnome panel : it's because I add it in the mainLayout. So how do I add it under the "gnome-panel". Thanks

• arg function not using URL alias

  - by cinqoTimo

  I am running Drupal 6, and I'm using PHP for block visibility. <?php $city = arg(0); $page = arg(1); if ($city == 'tampa' && $page != 'art'){ return 'TRUE'; } else{ return FALSE; } ?> I was having trouble with this block of code, so I decided to insert: <?php print arg(0).arg(1); ?> in my page.tpl.php. What I found was that on some of my pages, arg(0) was showing 'node' when the URL is actually 'tampa', and of course, arg(1) is showing the node ID. However, on other pages, such as my calendar, arg(0) is actually showing 'tampa' instead of 'node'. I have used this a lot in the past, and have never had this problem. Is there a reason why Drupal is disregarding my aliases on certain pages? If so, how can I fix it?

• ASP.Net MVC: Change Routes dynamically

  - by Frank

  Hi, usually, when I look at a ASP.Net MVC application, the Route table gets configured at startup and is not touched ever after. I have a couple of questions on that but they are closely related to each other: Is it possible to change the route table at runtime? How would/should I avoid threading issues? Is there maybe a better way to provide a dynamic URL? I know that IDs etc. can appear in the URL but can't see how this could be applicable in what I want to achieve. How can I avoid that, even though I have the default controller/action route defined, that default route doesn't work for a specific combination, e.g. the "Post" action on the "Comments" controller is not available through the default route? Background: Comment Spammers usually grab the posting URL from the website and then don't bother to go through the website anymore to do their automated spamming. If I regularly modify my post URL to some random one, spammers would have to go back to the site and find the correct post URL to try spamming. If that URL changes constantly I'd think that that could make the spammers' work more tedious, which should usually mean that they give up on the affected URL.

• Index question: Select * with WHERE clause. Where and how to create index

  - by Mestika

  Hi, I’m working on optimizing some of my queries and I have a query that states: select * from SC where c_id ="+c_id” The schema of ** SC** looks like this: SC ( c_id int not null, date_start date not null, date_stop date not null, r_t_id int not null, nt int, t_p decimal, PRIMARY KEY (c_id, r_t_id, date_start, date_stop)); My immediate bid on how the index should be created is a covering index in this order: INDEX(c_id, date_start, date_stop, nt, r_t_id, t_p) The reason for this order I base on: The WHERE clause selects from c_id thus making it the first sorting order. Next, the date_start and date_stop to specify a sort of “range” to be defined in these parameters Next, nt because it will select the nt Next the r_t_id because it is a ID for a specific type of my r_t table And last the t_p because it is just a information. I don’t know if it is at all necessary to order it in a specific way when it is a SELECT ALL statement. I should say, that the SC is not the biggest table. I can say how many rows it contains but a estimate could be between <10 and 1000. The next thing to add is, that the SC, in different queries, inserts the data into the SC, and I know that indexes on tables which have insertions can be cost ineffective, but can I somehow create a golden middle way to effective this performance. Don't know if it makes a different but I'm using IBM DB2 version 9.7 database Sincerely Mestika

• Is there a good web-based project management app with scheduling?

  - by Andykiteman

  Ideally something as intuitive as basecamp, with good usability and accessibility. The best I've seen is huddle.net but it's still weak in several areas. Must have: Projects - ability to add people & tasks and schedule tasks to people Calendar - showing when people are busy or available Role based access - Admins and non-admins History - ability to look back at all history Anyone seen a product that's worth a look? Clarification: Must be hosted i.e. not require my own hardware or IT staff I'm looking for an app to schedule people with specific tasks at specific times and monitor the outcomes. I'm already using Mingle (for stories), Basecamp (to run the business) and Exceptional (to track bugs). I'm not looking for a bug-tracking system or a story management application (I already looked at VersionOne, but chose Mingle due to it's nicer UI) My response to the answer being auto-selected: I still don't feel the answer (chosen for me) is the correct one. It's a useful list but little more, and doesn't provide the solution I was seeking.

• Sorting in Lua, counting number of items

  - by Josh

  Two quick questions (I hope...) with the following code. The script below checks if a number is prime, and if not, returns all the factors for that number, otherwise it just returns that the number prime. Pay no attention to the zs. stuff in the script, for that is client specific and has no bearing on script functionality. The script itself works almost wonderfully, except for two minor details - the first being the factor list doesn't return itself sorted... that is, for 24, it'd return 1, 2, 12, 3, 8, 4, 6, and 24 instead of 1, 2, 3, 4, 6, 8, 12, and 24. I can't print it as a table, so it does need to be returned as a list. If it has to be sorted as a table first THEN turned into a list, I can deal with that. All that matters is the end result being the list. The other detail is that I need to check if there are only two numbers in the list or more. If there are only two numbers, it's a prime (1 and the number). The current way I have it does not work. Is there a way to accomplish this? I appreciate all the help! function get_all_factors(number) local factors = 1 for possible_factor=2, math.sqrt(number), 1 do local remainder = number%possible_factor if remainder == 0 then local factor, factor_pair = possible_factor, number/possible_factor factors = factors .. ", " .. factor if factor ~= factor_pair then factors = factors .. ", " .. factor_pair end end end factors = factors .. ", and " .. number return factors end local allfactors = get_all_factors(zs.param(1)) if zs.func.numitems(allfactors)==2 then return zs.param(1) .. " is prime." else return zs.param(1) ..

• How do you make an added row from QueryAddRow() the first row of the result from a query?

  - by JS

  I am outputting a query but need to specify the first row of the result. I am adding the row with QueryAddRow() and setting the values with QuerySetCell(). I can create the row fine, I can add the content to that row fine. If I leave the argument for the row number off of QuerySetCell() then it all works great as the last result of the query when output. However, I need it to be first row of the query but when I try to set the row attribute with the QuerySetCell it just overwrites the first returned row from my query (i.e. my QueryAddRow() replaces the first record from my query). What I currently have is setting a variable from recordCount and arranging the output but there has to be a really simple way to do this that I am just not getting. This code sets the row value to 1 but overwrites the first returned row from the query. <cfquery name="qxLookup" datasource="#application.datasource#"> SELECT xID, xName, execution FROM table </cfquery> <cfset QueryAddRow(qxLookup)/> <cfset QuerySetCell(qxLookup, "xID","0",1)/> <cfset QuerySetCell(qxLookup, "xName","Delete",1)/> <cfset QuerySetCell(qxLookup, "execution", "Select this to delete",1)/> <cfoutput query="qxLookup"> <tr> <td> <a href="##" onclick="javascript:ColdFusion.navigate('xSelect/x.cfm?xNameVar=#url.xNameVar#&xID=#qxLookup.xID#&xName=#URLEncodedFormat(qxLookup.xName)#', '#xNameVar#');ColdFusion.Window.hide('#url.window#')">#qxLookup.xName#</a> </td> <td>#qxLookup.execution#</td> </tr> </cfoutput> </table> Thanks for any help.

• JQuery-AJAX: No further request after timeout and delay in form post

  - by Nogga

  I got a form containing multiple checkboxes. This form shall be sent to the server to receive appropriate results from a server side script. This is already working. What I would achieve now: 1) Implementing a timeout: This is already working, but as soon as a timeout occurs, a new request is not working anymore. 2) Implementing a delay in requesting results: A delay shall be implemented so that not every checkbox is resulting in a POST request. This is what I have right now: function update_listing() { // remove postings from table $('.tbl tbody').children('tr').remove(); // get the results through AJAX var request = $.ajax({ type: "POST", url: "http://localhost/hr/index.php/listing/ajax_csv", data: $("#listing_form").serialize(), timeout: 5000, success: function(data) { $(".tbl tbody").append(data); }, error: function(objAJAXRequest, strError) { $(".tbl tbody").append("<tr><td>failed " + strError + "</td></tr>"); } }); return true; } Results are for now passed as HTML table rows - I will transform them to CSV/JSON in the next step. Thanks so much for your advice.
