  • Session is Closed! NHibernate shouldn't be trying to grab data

    - by Jeremy Holovacs
    I have a UnitOfWork/Service pattern where I populate my model using NHibernate before sending it to the view. For some reason I still get the YSOD, and I don't understand why the object collection is not already populated. My controller method looks like this: public ActionResult PendingRegistrations() { var model = new PendingRegistrationsModel(); using (var u = GetUnitOfWork()) { model.Registrations = u.UserRegistrations.GetRegistrationsPendingAdminApproval(); } return View(model); } The service/unit of work looks like this: public partial class NHUserRegistrationRepository : IUserRegistrationRepository { public IEnumerable<UserRegistration> GetRegistrationsPendingAdminApproval() { var r = from UserRegistration ur in _Session.Query<UserRegistration>() where ur.Status == AccountRegistrationStatus.PendingAdminReview select ur; NHibernateUtil.Initialize(r); return r; } } What am I doing wrong?

  • Rails Multiple Table Inheritance question

    - by Tony
    I am starting to implement an MTI solution and have a basic question. I have 3 physical models - SMSNotifications, EmailNotifications, TwitterNotifications and they are subclasses of notification. At times in my code, I want to say Notifications.find(:all)so that I can get a set of results sorted by their creation time. Then I want to do things based on their subclass. What is the way to write Notifications.find(:all) and have Rails look through the subclass tables and combine the results? Right now Rails still thinks I have a physical Notifications table which goes against my MTI design. I am also considering the possibility that I should be using STI instead. I would probably have 10 empty columns per row but if getting all notifications requires a query for each type of notification, then I feel like this could be a big issue. Thanks!

  • can oracle types be updated like tables?

    - by Omnipresent
    I am converting GTT's to oracle types as explained in an excellent answer by APC. however, some GTT's are being updated based on a select query from another table. For example: UPDATE my_gtt_1 c SET (street, city, STATE, zip) = (SELECT src.unit_address, src.unit_city, src.unit_state, src.unit_zip_code FROM (SELECT mbr.ROWID row_id, unit_address, RTRIM(a.unit_city) unit_city, RTRIM(a.unit_state) unit_state, RTRIM(a.unit_zip_code) unit_zip_code FROM table_1 b, table_2 a, my_gtt_1 mbr WHERE type = 'ABC' AND id = b.ssn_head AND a.h_id = b.h_id AND row_id >= v_start_row AND row_id <= v_end_row) src WHERE c.ROWID = src.row_id) WHERE state IS NULL OR state = ' '; if my_gtt_1 was not a global temporary table but an oracle collection type then is it possible to do updates this complex? Or in these cases we are better off using the global temporary table?

  • SQL GROUP BY with "default values"

    - by Christoph Schiessl
    I'm trying to create SELECT statement with a GROUP BY clause, which should return "default values". Imagine the following simple MySQL table: CREATE TABLE `tracker` ( `id` INTEGER PRIMARY KEY auto_increment, `date` DATETIME NOT NULL, `customer_id` INTEGER NOT NULL ); The table contains only one record: INSERT INTO `tracker` (`date`, `customer_id`) VALUES('2010-05-03', 1); After wards I'm executing the following SQL query: SELECT DATE(`date`), COUNT(customer_id) FROM tracker WHERE DATE(`date`) >= '2010-05-01' AND DATE(`date`) <= '2010-05-05' GROUP BY DATE(`date`) ORDER BY DATE(`date`); And get the expected result set: +----+---------------------+-------------+ | id | date | customer_id | +----+---------------------+-------------+ | 1 | 2010-05-10 00:00:00 | 1 | +----+---------------------+-------------+ However, I would like the result set to look like this: +--------------+--------------------+ | DATE(`date`) | COUNT(customer_id) | +--------------+--------------------+ | 2010-05-01 | 0 | | 2010-05-02 | 0 | | 2010-05-03 | 1 | | 2010-05-04 | 0 | | 2010-05-05 | 0 | +--------------+--------------------+ Is it possible to achieve this behavior?

    I am having trouble with an assertQuery(). In the html I have (verified by outputting the body) <input type="text" name="LASTNAME" id="LASTNAME" value="" maxlength="25" size="20" /> So I wrote a query for it to test to make sure this element exists and that the value is empty $this->assertQuery('input#LASTNAME[value=""]', 1); PhpUnit says the assertion fails Failed asserting node DENOTED BY input#LASTNAME[value=""] EXISTS Can you give me some insight into why this assertion fails and how to write it properly? Thanks in advance!

  • Towards Ultra-Reusability for ADF - Adaptive Bindings

    - by Duncan Mills
    The task flow mechanism embodies one of the key value propositions of the ADF Framework, it's primary contribution being the componentization of your applications and implicitly the introduction of a re-use culture, particularly in large applications. However, what if we could do more? How could we make task flows even more re-usable than they are today? Well one great technique is to take advantage of a feature that is already present in the framework, a feature which I will call, for want of a better name, "adaptive bindings". What's an adaptive binding? well consider a simple use case.  I have several screens within my application which display tabular data which are all essentially identical, the only difference is that they happen to be based on different data collections (View Objects, Bean collections, whatever) , and have a different set of columns. Apart from that, however, they happen to be identical; same toolbar, same key functions and so on. So wouldn't it be nice if I could have a single parametrized task flow to represent that type of UI and reuse it? Hold on you say, great idea, however, to do that we'd run into problems. Each different collection that I want to display needs different entries in the pageDef file and: I want to continue to use the ADF Bindings mechanism rather than dropping back to passing the whole collection into the taskflow   If I do use bindings, there is no way I want to have to declare iterators and tree bindings for every possible collection that I might want the flow to handle  Ah, joy! I reply, no need to panic, you can just use adaptive bindings. Defining an Adaptive Binding  It's easiest to explain with a simple before and after use case.  Here's a basic pageDef definition for our familiar Departments table.  <executables> <iterator Binds="DepartmentsView1" DataControl="HRAppModuleDataControl" RangeSize="25"             id="DepartmentsView1Iterator"/> </executables> <bindings> <tree IterBinding="DepartmentsView1Iterator" id="DepartmentsView1">   <nodeDefinition DefName="oracle.demo.model.vo.DepartmentsView" Name="DepartmentsView10">     <AttrNames>       <Item Value="DepartmentId"/>         <Item Value="DepartmentName"/>         <Item Value="ManagerId"/>         <Item Value="LocationId"/>       </AttrNames>     </nodeDefinition> </tree> </bindings>  Here's the adaptive version: <executables> <iterator Binds="${pageFlowScope.voName}" DataControl="HRAppModuleDataControl" RangeSize="25"             id="TableSourceIterator"/> </executables> <bindings> <tree IterBinding="TableSourceIterator" id="GenericView"> <nodeDefinition Name="GenericViewNode"/> </tree> </bindings>  You'll notice three changes here.   Most importantly, you'll see that the hard-coded View Object name  that formally populated the iterator Binds attribute is gone and has been replaced by an expression (${pageFlowScope.voName}). This of course, is key, you can see that we can pass a parameter to the task flow, telling it exactly what VO to instantiate to populate this table! I've changed the IDs of the iterator and the tree binding, simply to reflect that they are now re-usable The tree binding itself has simplified and the node definition is now empty.  Now what this effectively means is that the #{node} map exposed through the tree binding will expose every attribute of the underlying iterator's collection - neat! (kudos to Eugene Fedorenko at this point who reminded me that this was even possible in his excellent "deep dive" session at OpenWorld  this year) Using the adaptive binding in the UI Now we have a parametrized  binding we have to make changes in the UI as well, first of all to reflect the new ID that we've assigned to the binding (of course) but also to change the column list from being a fixed known list to being a generic metadata driven set: <af:table value="#{bindings.GenericView.collectionModel}" rows="#{bindings.GenericView.rangeSize}"         fetchSize="#{bindings.GenericView.rangeSize}"           emptyText="#{bindings.GenericView.viewable ? 'No data to display.' : 'Access Denied.'}"           var="row" rowBandingInterval="0"           selectedRowKeys="#{bindings.GenericView.collectionModel.selectedRow}"           selectionListener="#{bindings.GenericView.collectionModel.makeCurrent}"           rowSelection="single" id="t1"> <af:forEach items="#{bindings.GenericView.attributeDefs}" var="def">   <af:column headerText="#{bindings.GenericView.labels[def.name]}" sortable="true"            sortProperty="#{def.name}" id="c1">     <af:outputText value="#{row[def.name]}" id="ot1"/>     </af:column>   </af:forEach> </af:table> Of course you are not constrained to a simple read only table here.  It's a normal tree binding and iterator that you are using behind the scenes so you can do all the usual things, but you can see the value of using ADFBC as the back end model as you have the rich pantheon of UI hints to use to derive things like labels (and validators and converters...)  One Final Twist  To finish on a high note I wanted to point out that you can take this even further and achieve the ultra-reusability I promised. Here's the new version of the pageDef iterator, see if you can notice the subtle change? <iterator Binds="{pageFlowScope.voName}"  DataControl="${pageFlowScope.dataControlName}" RangeSize="25"           id="TableSourceIterator"/>  Yes, as well as parametrizing the collection (VO) name, we can also parametrize the name of the data control. So your task flow can graduate from being re-usable within an application to being truly generic. So if you have some really common patterns within your app you can wrap them up and reuse then across multiple developments without having to dictate data control names, or connection names. This also demonstrates the importance of interacting with data only via the binding layer APIs. If you keep any code in the task flow generic in that way you can deal with data from multiple types of data controls, not just one flavour. Enjoy!

  • Solr date field tdate vs date?

    - by user550178
    So I have a question about Solr's field date types which is pretty straight forward: what's the difference between a 'date' field and a 'tdate' one? The schema .xml claims that 'For faster range queries, consider the tdate type' and 'A Trie based date field for faster date range queries and date faceting. ' Fair enough... but what's the precisionStep="6" all about? should i change this? does it change the way i would create the query in case I use the tdate? What's the real advantage or what does Solr do that makes it better? P.S went through google, Solr manual, solr wiki and the java docs without any luck so I'd appreciate a kind and explanatory answer :)... Also checked: http://www.lucidimagination.com/blog/2009/05/13/exploring-lucene-and-solrs-trierange-capabilities/ http://web.archiveorange.com/archive/v/AAfXfqRYyLnDFtskmLRi

    I've a nice situation, I think at beginning this a usual query but I'm having some problem trying to solve this, the situation is: I've a list of "Houses", and each house have a list of "Windows". And I want to filter for a catalog only the Houses witch have a Blue windows, so my extension method of House is something like: public static List<House> FilterByWindow (this IEnumerable<House> houses, Window blueOne){ houses.Select(p=>p.Windows.Where(q=>q.Color == blueOne.Color)); return houses.ToList(); } Is this correct or I'm losing something? Some better suggestion?

  • Passing Results from SQL to Google Maps API in CodeIgniter

    - by Jason Shultz
    I'm hoping to use google maps on my site. My addresses are stored in a db. I’m pulling up a page where the information is all dynamic. For example: mysite.com/site/business/5 (where 5 is the id of the business). Let’s say I do a query like this: function addressForMap($id) { $this->db->select(‘b.id, b.busaddress, b.buscity, b.buszip’); $this->db->from(‘business as b’); $this->db->where(‘b.id, $id); } How can I output the info to the google maps api correctly so that it display’s the map appropriately? The API interface takes the results like this: $marker['address'] = 'Crescent Park, Palo Alto';

  • Getting a value from a row at particular time

    - by Swetha Bindu
    I had a row in my database: starttime:4/6/2012 2:00pm, Endtime:31/12/9999, name:"swetha", status:"open"..... When I update this row I changed the starttime to the current time (getdate()) and have no issues. I am running a Windows Service each day at 1am to modify a value in the row. I would like to know the status of my row at 4/6/2012 11:59 pm when my service runs. There is no need to do an update at 4/6/2012 11:59 pm and the last update may be at any time of the day however my requirement is to get the status value at 4/6/2012 11:59 pm. I would like to have the query in SQL Server 2008. Can anyone please help me to find a solution?

  • SQL optional parameters through VB.net

    - by ScaryJones
    I've a document search page with three listboxes that allow multiple selections. They're: Category A Year Category B Only category A is mandatory, the others are optional parameters and might be empty. Each document can belong to multiple options in Category A and multiple options Category B but each document only has one year associated with it. I've kind of got this working through building up a dynamic SQL string but it's messy and I hate using it so I thought I'd ask here if anyone could see an easier way of doing this. An example of the kind of dynamic SQL query i end up with follows: select * from library where libraryID in (select distinct libraryID from categoryAdocs where categoryAdocID in (4)) or year in (2004)

  • How to use R-Tree for plotting large number of map markers on google maps

    - by Eeyore
    After searching SO and multiple articles I haven't found a solution to my problem. What I am trying to achieve is to load 20,000 markers on Google Maps. R-Tree seems like a good approach but it's only helpful when searching for points within the visible part of the map. When the map is zoomed out it will return all of the points and...crash the browser. There is also the problem with dragging the map and at the end of dragging re-running the query. I would like to know how I can use R-Tree and be able to achieve the all of the above.

  • Access DoCmd.OpenForm Not Working

    - by user961743
    Looking for a second set of eyes to figure out my problem with an Access form filter. I created a search form, when filled in, appends search criteria to a string variable (strQuery) that is put in place to the [WhereCondition] for opening a form. However, when the script is ran, nothing comes up except for a filtered form with no records. Here is the line that opens the form: DoCmd.OpenForm "ADD_NEW_NCMR", , , strQuery Before the line is ran, strQuery equals: 1=1 AND [NCMR].[NCMR_NUM] = '12-129' The form name, and table.column combination are all correct. In fact, using the DCount function returns the result of 1, which is correct for this query, and returns the correct number for other queries as well. This makes me think that there is nothing wrong with the where condition. DCount("[NCMR_NUM]", "NCMR", strQuery)

  • How to debug when CakePHP Model::save() doesn't attempt an INSERT

    - by RyOnLife
    I am having a bear of a time saving the simplest record from a model called ItemView: if($this->save($this->data)) { echo 'worked'; } else { echo 'failed'; } Where $this-data is: Array ( [ItemView] => Array ( [list_id] => 1 [user_id] => 1 ) ) And my table is: CREATE TABLE IF NOT EXISTS `item_views` ( `id` int(11) NOT NULL auto_increment, `list_id` int(11) NOT NULL, `user_id` int(11) default NULL, `user_ip` int(10) unsigned default NULL, `created` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ROW_FORMAT=FIXED AUTO_INCREMENT=1 ; Looking at the query dump in debug mode, Cake isn't even attempting an INSERT, so I have no idea how to debug. Any help would be appreciated.

  • Web Search API which allows automated queries

    - by Spi1988
    I need to develop a java desktop application which sends queries to a search engine in order to obtain the very first highest ranked pages (Example: the first 4 pages only). Some heavy processing needs to be performed on the retrieved pages, so the time between a query and another won't be less then a minute. I would like to know whether there is any web search API for java, suitable for my situation, i.e. which allows the use of automated queries? (since in my case, the queries are generated programatically, and not through user interaction) I have checked Google's AJAX Search API and also Yahoo's Search Boss, however they only allow queries triggered by direct user interaction.

  • Nested sql queries in rails when :has_and_belongst_to_many

    - by Godisemo
    Hello, In my application I the next task that has not already been done by a user. I have Three models, A Book that has many Tasks and then I have a User that has has and belongs to many tasks. The table tasks_users table contains all completed tasks so I need to write a complex query to find the next task to perform. I have came up with two solutions in pure SQL that works, but I cant translate them to rails, thats what I need help with SELECT * FROM `tasks` WHERE `tasks`.`book_id` = @book_id AND `tasks`.`id` NOT IN ( SELECT `tasks_users`.`task_id` FROM `tasks_users` WHERE `tasks_users`.`user_id` = @user_id) ORDER BY `task`.`date` ASC LIMIT 1; and equally without nested select SELECT * FROM tasks LEFT JOIN tasks_users ON tasks_users.tasks_id = task.id AND tasks_users.user_id = @user_id WHERE tasks_users.task_id IS NULL AND tasks.book_id = @book_id LIMIT 1; This is what I Have done in rails with the MetaWhere plugin book.tasks.joins(:users.outer).where(:users => {:id => nil}) but I cant figure out how to get the current user there too, Thanks for any help!

  • How to extract all IDs accessed from a mysql general log using the linux commandline?

    - by shlomoid
    This should be a trivial question for anyone who's good with bash/sed/awk. Unfortunately, I'm not, yet :) I've got a general log from MySQL which contains some queries that have a common parameter, they query on a specific id field. The queries look like update tbl set col='binary_values' where id=X; I need to process the log and extract all the IDs that these queries touched, each in it's own line. The purpose of this is to figure out how many times each ID is accessed. Eventually I'd group and count the values. The binary values are indeed binary junk, so they kinda messed up some things I've been trying to do. Eventually we solved the problem temporarily using a python script, but I'm sure the linux command line tool set can do it too. How would you do it?

  • linq to sql string property from non-null column with default

    - by Barry Fandango
    I have a LINQ to SQL class "VoucherRecord" based on a simple table. One property "Note" is a string that represents an nvarchar(255) column, which is non-nullable and has a default value of empty string (''). If I instantiate a VoucherRecord the initial value of the Note property is null. If I add it using a DataContext's InsertOnSubmit method, I get a SQL error message: Cannot insert the value NULL into column 'Note', table 'foo.bar.tblVoucher'; column does not allow nulls. INSERT fails. Why isn't the database default kicking in? What sort of query could bypass the default anyway? How do I view the generated sql for this action? Thanks for your help!

  • Good error flagging | PHP

    - by Wayne
    For everyone that was thinking of the error_reporting() function, then it isn't, what I need is whenever a MySQL query has been done, and the statement has like if($result) { echo "Yes, it was fine... bla bla"; } else { echo "Obviously, the echo'ing will show in a white page with the text ONLY..."; } Whenever statements have been true or false, I want the error to be appeared when redirected with the header() function and echo the error reporting in a div somewhere on the page. Basically something like this: $error = ''; This part appears inside the div tags <div><?php echo $error; ?></div> So the error part will be echoed when redirected with the header() if($result) { $error = "Yes, it was fine... bla bla"; header("Location: url"); } else { $error = "Something wrong happened..."; header("Location: url"); } But that just doesn't work :(

  • Simplest way to use a DatagridView with Linq to SQL

    - by Martín Marconcini
    Hi, I have never used datagrids and such, but today I came across a simple problem and decided to "databind" stuff to finish this faster, however I've found that it doesn't work as I was expecting. I though that by doing something as simple as: var q = from cust in dc.Customers where cust.FirstName == someString select cust; var list = new BindingList<Customer>(q.ToList()); return list; Then using that list in a DataGridView1.DataSource was all that I needed, however, no matter how much I google, I can't find a decent example on how to populate (for add/edit/modify) the results of a single table query into a DataGridView1. Most samples talk about ASP.NET which I lack, this is WinForms. Any ideas? I've came across other posts and the GetNewBindingList, but that doesn't seem to change much. What am I missing (must be obvious)? Thanks in advance. Martin.
