  • Why does XPath.selectNodes(context) always use the whole document in JDOM

    - by Simeon
    Hi, I'm trying to run the same query on several different contexts, but I always get the same result. This is an example xml: <root> <p> <r> <t>text</t> </r> </p> <t>text2</t> </root> So this is what I'm doing: final XPath xpath = XPath.newInstance("//t"); List<Element> result = xpath.selectNodes(thisIsThePelement); // and I've debuged it, it really is the <p> element And I always get both <t> elements in the result list. I need just the <t> inside the <p> I'm passing to the XPath object. Any ideas would be of great help, thanks.

  • Using MongoDB's map/reduce to "group by" two fields

    - by ibz
    I need something slightly more complex than the examples in the MongoDB docs and I can't seem to be able to wrap my head around it. Say I have a collection of objects of the form {date: "2010-10-10", type: "EVENT_TYPE_1", user_id: 123, ...} Now I want to get something similar to a SQL GROUP BY query, grouping over both date and type. That is, I want the number of events of each type in each day. Also, I'd like to make it unique by user_id, ie. if a user has more events in the same day, count it only once. I'm trying to do this with map/reduce. I do db.logs.mapReduce(function() { emit(this.type, 1); }, function(k, vals) { var total = 0; for (var i = 0; i < vals.length; i++) total += vals[i]; return total; }}) which nicely groups by type, but now, how can I group by date at the same time? Seems the key in emit() can't be an array (I thought about doing emit([this.date, this.type], 1)). Also, how can I ensure the per-user uniqueness? I'm just starting with MongoDB and I'm still having trouble grasping the basic concepts. Also, there is not much documentation available out there. Any help from more experienced users is appreciated. Thanks!

  • Applying for .net jobs as a "self learner"

    - by DeanMc
    Hi All, I have recently started applying for .Net jobs. I currently work in a sales role with a large telco. I found out quite late that I like programming and as such bought my house and made commitments that mean college is not an option. What I would like to know is, is it harder to get a junior job as a self learner? I have gotten a few enquiries regarding my C.V but nothing concrete yet. I try to be involved in projects as I get the chance and tend to put up any worthwhile projects as I develop them. Some examples of my work are: A Xaml lexer and parser: http://www.xlight.mendhak.com A font obfuscation tool: http://www.silverlightforums.com/showthread.php?1516-Font-Obsfucation-Tool-ALPHA A tagger for m4a: http://projectaudiophile.codeplex.com/SourceControl/list/changesets I, of course think that these are great examples of my work but that is my opinion based on self learning. The other query is how much should I actually know? I've never used linked lists but I know that strings are immutable and I understand what that means. I am only touching on T-SQL but I understand things like how properties function in IL (as two standard methods :) ). I suppose I understand a lot of concepts but specific features need some looking up to implement as I may not know the syntax off the top of my head.

  • archiving strategies and limitations of data in a table

    - by Samuel
    Environment: Jboss, Mysql, JPA, Hibernate Our web application will be catering to a large amount of users (~ 1,000,000) and there are a lots of child table where user specific data are stored (e.g. personal, health, forum contributions ...). What would be the best practice to archive user & user specific information. [a] Would it be wise to move the archived user & user specific information to their respective tables within the same database (e.g. user_archive, user_forum_comments_archive ...) OR [b] Would you just mark the database entries with a flag in the original table(s) and just query only non archived entries. We have a unique constraint on User.loginid, how do you handle this requirement if the users are archived via 1-[a] (i.e if a user with loginid 'samuel' gets moved into the archive table and if a new user gets added with the same name in the original table, how would you prevent this. What would be the best strategy to address the unique key constraints. We have a requirement to selectively archive records and bring it back if necessary, will you rely on database tools are would you handle this via your persistence APIs exposed by the JPA entity model.

  • Populate an SSRS Report parameter(hidden) by a sproc or user defined function

    - by Nauman
    My SSRS report fetches data from my DATAWAREHOUSE. The ASP.NET application I have is connected to an OLTP database. I invoke the SSRS Report from my ASP.NET application and provide a parameter as CustomerID(this is an application key in datawarehouse) to my report. Since my report is connected to my datawarehouse, I do not query my report databased on the OLTP's CustomerID. Instead I use my datawarehouse's surrogate key (CustomerDimKey). Now, in my report, I need to find the correct surrogate key for the CustomerID parameter, which I passed from my ASP.NET application! My report already has a parameter as @CustomerDimKey(this is used across all the report sprocs). We used it for testing, but now we'll hide this as we have integrated it with the ASP.NET application. I have already added a new parameter to the report as @CustomerID(this will have the OLTP's CustomerID), which will now get a value from ASP.NET. I need to know a way to re-use the @CustomerDimKey report parameter, which should now get value from a sql statement or a sproc once the report is requested. Based on the value contained by the @CustomerID parameter.

  • Escape Quote in C# for javascript consumption

    - by Jason
    I have a ASP.Net web handler that returns results of a query in JSON format public static String dt2JSON(DataTable dt) { String s = "{\"rows\":["; if (dt.Rows.Count > 0) { foreach (DataRow dr in dt.Rows) { s += "{"; for (int i = 0; i < dr.Table.Columns.Count; i++) { s += "\"" + dr.Table.Columns[i].ToString() + "\":\"" + dr[i].ToString() + "\","; } s = s.Remove(s.Length - 1, 1); s += "},"; } s = s.Remove(s.Length - 1, 1); } s += "]}"; return s; } The problem is that sometimes the data returned has quotes in it and I would need to javascript-escape these so that it can be properly created into a js object. I need a way to find quotes in my data (quotes aren't there every time) and place a "/" character in front of them. Example response text (wrong): {"rows":[{"id":"ABC123","length":"5""}, {"id":"DEF456","length":"1.35""}, {"id":"HIJ789","length":"36.25""}]} I would need to escape the " so my response should be: {"rows":[{"id":"ABC123","length":"5\""}, {"id":"DEF456","length":"1.35\""}, {"id":"HIJ789","length":"36.25\""}]} Also, I'm pretty new to C# (coding in general really) so if something else in my code looks silly let me know.

  • How to get height for NSAttributedString at a fixed width

    - by bonaldi
    I want to do some drawing of NSAttributedStrings in fixed-width boxes, but am having trouble calculating the right height they'll take up when drawn. So far, I've tried: Calling - (NSSize) size, but the results are useless (for this purpose), as they'll give whatever width the string desires. Calling - (void)drawWithRect:(NSRect)rect options:(NSStringDrawingOptions)options with a rect shaped to the width I want and NSStringDrawingUsesLineFragmentOrigin in the options, exactly as I'm using in my drawing. The results are ... difficult to understand; certainly not what I'm looking for. (As is pointed out in a number of places, including this Cocoa-Dev thread). Creating a temporary NSTextView and doing: [[tmpView textStorage] setAttributedString:aString]; [tmpView setHorizontallyResizable:NO]; [tmpView sizeToFit]; When I query the frame of tmpView, the width is still as desired, and the height is often correct ... until I get to longer strings, when it's often half the size that's required. (There doesn't seem to be a max size being hit: one frame will be 273.0 high (about 300 too short), the other will be 478.0 (only 60-ish too short)). I'd appreciate any pointers, if anyone else has managed this.

  • Is there a tag in XHTML that you can put anywhere in the body - even inside TABLE elements?

    - by Iain Fraser
    I would like to be able to place an empty tag anywhere in my document as a marker that can be addressed by jQuery. However, it is important that the XHTML still validates. To give you a bit of background as to what I'm doing: I've compared the current and previous versions of a particular document and I'm placing markers in the html where the differences are. I'm then intending to use jQuery to highlight the parent block-level elements when highlightchanges=true is in the URL's query string. At the moment I'm using <span> tags but it occurred to me that this sort of thing wouldn't validate: <table> <tr> <td>Old row</td> </tr> <span class="diff"></span><tr> <td>Just added</td> </tr> </table> So is there a tag I can use anywhere? Meta tag maybe? Thanks for your help! Iain

  • What is the best database structure for this scenario?

    - by Ricketts
    I have a database that is holding real estate MLS (Multiple Listing Service) data. Currently, I have a single table that holds all the listing attributes (price, address, sqft, etc.). There are several different property types (residential, commercial, rental, income, land, etc.) and each property type share a majority of the attributes, but there are a few that are unique to that property type. My question is the shared attributes are in excess of 250 fields and this seems like too many fields to have in a single table. My thought is I could break them out into an EAV (Entity-Attribute-Value) format, but I've read many bad things about that and it would make running queries a real pain as any of the 250 fields could be searched on. If I were to go that route, I'd literally have to pull all the data out of the EAV table, grouped by listing id, merge it on the application side, then run my query against the in memory object collection. This also does not seem very efficient. I am looking for some ideas or recommendations on which way to proceed. Perhaps the 250+ field table is the only way to proceed. Just as a note, I'm using SQL Server 2012, .NET 4.5 w/ Entity Framework 5, C# and data is passed to asp.net web application via WCF service. Thanks in advance.

  • How can I filter a Perl DBIx recordset with 2 conditions on the same column?

    - by BrianH
    I'm getting my feet wet in DBIx::Class - loving it so far. One problem I am running into is that I want to query records, filtering out records that aren't in a certain date range. It took me a while to find out how to do a "<=" type of match instead of an equality match: my $start_criteria = ">= $start_date"; my $end_criteria = "<= $end_date"; my $result = $schema->resultset('MyTable')->search( { 'status_date' => \$start_criteria, 'status_date' => \$end_criteria, }); The obvious problem with this is that since the filters are in a hash, I am overwriting the value for "status_date", and am only searching where the status_date <= $end_date. The SQL that gets executed is: SELECT me.* from MyTable me where status_date <= '9999-12-31' I've searched CPAN, Google and SO and haven't been able to figure out how to apply 2 conditions to the same column. All documentation I've been able to find shows how to filter on more than 1 column, but not 2 conditions on the same column. I'm sure I'm missing something obvious - hoping someone here can point it out to me? Thanks in advance! Brian

  • Saving HttpResponse/Request to file system

    - by chrisjlong
    Here is my scenario. User fills out this large page which is dynamically created based off DB values. Those values can change. When the user fills out the page and hits submit we want to save a copy of the page as html on the server, this way if the text or wording changes, when they go back to view their posted information, it is historically accurate. So I basically need to do this protected void buttonSave_Click(object sender, EventArgs e) { //collect information into an object to save it in the db bool result = BusinessLogic.Save(myBusinessObject); if (result) //!!! Here is where I need to save this page as an html file on my servers IFS!!!! else //whatever Response.Redirect("~/SomeOtherPage.aspx"); } Any help is greatly apprciated. Also I CANNOT just request the data from the url because query string parameters are a big no no in this case. The key to pull the database info up (at its highest level) is all in session so I cant just request a url and save it. Thanks!

  • Use an Array to Cycle Through a MySQL Where Statement

    - by Ryan
    I'm trying to create a loop that will output multiple where statements for a MySQL query. Ultimately, my goal is to end up with these four separate Where statements: `fruit` = '1' AND `vegetables` = '1' `fruit` = '1' AND `vegetables` = '2' `fruit` = '2' AND `vegetables` = '1' `fruit` = '2' AND `vegetables` = '2' My theoretical code is pasted below: <?php $columnnames = array('fruit','vegetables'); $column1 = array('1','2'); $column2 = array('1','2'); $where = ''; $column1inc =0; $column2inc =0; while( $column1inc <= count($column1) ) { if( !empty( $where ) ) $where .= ' AND '; $where = "`".$columnnames[0]."` = "; $where .= "'".$column1[$column1inc]."'"; while( $column2inc <= count($column2) ) { if( !empty( $where ) ) $where .= ' AND '; $where .= "`".$columnnames[1]."` = "; $where .= "'".$column2[$column2inc]."'"; echo $where."\n"; $column2inc++; } $column1inc++; } ?> When I run this code, I get the following output: `fruit` = '1' AND `vegetables` = '1' `fruit` = '1' AND `vegetables` = '1' AND `vegetables` = '2' `fruit` = '1' AND `vegetables` = '1' AND `vegetables` = '2' AND `vegetables` = '' Does anyone see what I am doing incorrectly? Thanks.

  • Session Variable Not Being Updated? ASP.NET

    - by davemackey
    I have a three step wizard. On the first step I use a repeater to create a series of buttons that an individual can select from. When the user selects one of the buttons the value of the button is saved to session state. They are taken to the next step and shown a similar list of buttons that are based on what they previously selected. Thus, if you choose "Hamburger" you might receive the options of "onion", "lettuce", "tomato" while if you choose "Hot Dog" you might receive "sauerkraut" and "ketchup". Lets say an individual chooses Hamburger. This is saved into session state like so: Public Sub Button_ItemCommand(ByVal Sender As Object, ByVal e As RepeaterCommandEventArgs) ' ******** Lets pass on the results of our query in LinqDataSource1_Selecting. Session("food_select") = RTrim(e.CommandName) Wizard1.ActiveStepIndex = 1 End Sub Now, this works fine and dandy. But lets say I select hamburger and then realize I'm really hankering for a hot dog. I go back to the first wizard step and click on the hot dog button - but when the wizard progresses to the next step I still see the options for hamburgers! The session variable has not been updated. Why? Thanks!

  • How to store a list in a column of a database table.

    - by John Berryman
    Howdy! So, per Mehrdad's answer to a related question, I get it that a "proper" database table column doesn't store a list. Rather, you should create another table that effectively holds the elements of said list and then link to it directly or through a junction table. However, the type of list I want to create will be composed of unique items (unlike the linked question's fruit example). Furthermore, the items in my list are explicitly sorted - which means that if I stored the elements in another table, I'd have to sort them every time I accessed them. Finally, the list is basically atomic in that any time I wish to access the list, I will want to access the entire list rather than just a piece of it - so it seems silly to have to issue a database query to gather together pieces of the list. AKX's solution (linked above) is to serialize the list and store it in a binary column. But this also seems inconvenient because it means that I have to worry about serialization and deserialization. Is there any better solution? If there is no better solution, then why? It seems that this problem should come up from time to time. ... just a little more info to let you know where I'm coming from. As soon as I had just begun understanding SQL and databases in general, I was turned on to LINQ to SQL, and so now I'm a little spoiled because I expect to deal with my programming object model without having to think about how the objects are queried or stored in the database. Thanks All! John

  • Should I remove all inheritance from my model in order to work with ria services?

    - by TimothyP
    I've posted some questions on this before, but it's different. So consider a small portion of our model: Person Customer Employee Spouse Person is the base class which has 3 classes that inherit from it. These 4 are very central in our design and link to many other entities. I could solve all the problems I'm experiencing with ria-services by removing the inheritance but that would really increase the complexety of the model. The first problem I experienced was that I couldn't query for Customers, Employees or Spouses, but someone gave me a solution, which was to add something like this to the DomainService: public IQueryable<Employee> GetEmployees() { return this.ObjectContext.People.OfType<Employee>(); } public IQueryable<Customer> GetCustomers() { return this.ObjectContext.People.OfType<Customer>(); } public IQueryable<Spouse> GetSpouses() { return this.ObjectContext.People.OfType<Spouse>(); } Next I tried something that seemed very normal to me: var employee = new Employee() { //.... left out to reduce the length of this question }; var spouse = new Spouse() { //.... left out to reduce the length of this questions }; employee.Spouse = spouse; context.People.Add(spouse); context.People.Add(employee); context.SubmitChanges(); Then I get the following exception: Cannot retrieve an entity set for the derived entity type 'Spouse'. Use EntityContainer.GetEntitySet(Type) to get the entity set for the base entity type 'Person'. Even when the spouse is already in the database, and I retreive it first I get similar exceptions. Also note that for some reason in some places "Persons" is used instead of "People"... So how do I solve this problem, what am I doing wrong and will I keep running into walls when using ria services with inheritance? I found some references on the web, all saying it works and then some DomainService code in which they suposedly changed something but no details... I'm using VS2010 RC1 + Silveright 4

  • Generate an ID via COM interop

    - by Erik van Brakel
    At the moment, we've got an unmaintanable ball of code which offers an interface to a third party application. The third party application has a COM assembly which MUST be used to create new entries. This process involves two steps: generate a new object (basically an ID), and update that object with new field values. Because COM interop is so slow, we only use that to generate the ID (and related objects) in the database. The actual update is done using a regular SQL query. What I am trying to figure out if it's possible to use NHibernate to do some of the heavy lifting for us, without bypassing the COM assembly. Here's the code for saving something to the database as I envision it: using(var s = sessionFactory.OpenSession()) using(var t = s.BeginTransaction()) { MyEntity entity = new MyEntity(); s.Save(entity); t.Commit(); } Regular NH code I'd say. Now, this is where it gets tricky. I think I have to supply my own implementation of NHibernate.Id.IIdentifierGenerator which calls the COM assembly in the Generate method. That's not a problem. What IS a problem is that the COM assembly requires initialisation, which does take a bit of time. It also doesn't like multiple instances in the same process, for some reason. What I would like to know is if there's a way to properly access an external service in the generator code. I'm free to use any technique I want, so if it involves something like an IoC container that's no problem. The thing I am looking for is where exactly to hook-up my code so I can access the things I need in my generator, without having to resort to using singletons or other nasty stuff.

  • Uninterruptible Windows Process

    - by Nullstr1ng
    Hi Guys, We're starting a new custom project right now from a client and one of the requirements is the process cannot be terminated unless the system is shutting down, restarting, or logging-off. This application monitors the USB interface. We will be using WMI to query the device periodically. The client want's to run the application on Windows XP Operating System and doesn't like installing .NET. So we targeted Visual Basic 6 as our language. My main concern is this application cannot be terminated. Our Project Adviser talks about Anti-virus and yes, some of the anti virus cannot be terminated. I was thinking how to do the same in Visual Basic 6. I know there will be API involved on the project but where should I go? so API is ok with me. I saw some articles that converts the EXE to a SERVICE, create Windows Service in Visual Basic 6, etc. So please .. share your thoughts.

If you have two classes: class A { @Id public Long id; } class B { @Id public Long id; @ManyToOne @JoinColumn(name = "parent_id", referencedColumnName = "id") public A parent; } B - A is a many to one relationship. I understand that I could add a Collection of Bs to A however I do not want that association. So my actual question is, Is there an HQL or Criteria way of creating the SQL query: select * from A left join B on (b.parent_id = a.id) This will retrieve all A records with a Cartesian product of each B record that references A and will include A records that have no B referencing them. If you use: from A a, B b where b.a = a then it is an inner join and you do not receive the A records that do not have a B referencing them. I have not found a good way of doing this without two queries so anything less than that would be great. Thanks.

  • Setting Connection Parameters via ADO for MSSQL

    - by taspeotis
    Is it possible to set a connection parameter on a connection to SQL Server and have that variable persist throughout the life of the connection? The parameter must be usable by subsequent queries. We have some old Access reports that use a handful of VBScript functions in the SQL queries (let's call them GetStartDate and GetEndDate) that return global variables. Our application would set these before invoking the query and then the queries can return information between date ranges specified in our application. We are looking at changing to a ReportViewer control running in local mode, but I don't see any convenient way to use these custom functions in straight T-SQL. I have two concept solutions (not tested yet), but I would like to know if there is a better way. Below is some psuedo code. Set all variables before running Recordset.OpenForward Connection->Execute("SET @GetStartDate = ..."); Connection->Execute("SET @GetEndDate = ..."); // Repeat for all parameters Will these variables persist to later calls of Recordset->OpenForward? Can anything reset the variables aside from another SET/SELECT @variable statement? Create an ADOCommand "factory" that automatically adds parameters to each ADOCommand object I will use to execute SQL // Command has been previously been created ADOParameter *Parameter1 = Command->CreateParameter("GetStartDate"); ADOParameter *Parameter2 = Command->CreateParameter("GetEndDate"); // Set values and attach etc... What I would like to know if there is something like: Connection->SetParameter("GetStartDate", "20090101"); Connection->SetParameter("GetEndDate", 20100101"); And these will persist for the lifetime of the connection, and the SQL can do something like @GetStartDate to access them. This may be exactly solution #1, if the variables persist throughout the lifetime of the connection.

  • t-sql most efficient row to column? crosstab for xml path, pivot

    - by ajberry
    I am looking for the most performant way to turn rows into columns. I have a requirement to output the contents of the db (not actual schema below, but concept is similar) in both fixed width and delimited formats. The below FOR XML PATH query gives me the result I want, but when dealing with anything other than small amounts of data, can take awhile. select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o I've looked at pivot but most of the examples I have found are aggregating information. I just want to combine the child rows and tack them onto the parent. I should also point out I don't need to deal with the column names either since the output of the child rows will either be a fixed width string or a delimited string. For example, given the following tables: OrderId CustomerId ----------- ----------- 1 1 2 2 3 3 DetailId OrderId ProductId ----------- ----------- ----------- 1 1 100 2 1 158 3 1 234 4 2 125 5 3 101 6 3 105 7 3 212 8 3 250 for an order I need to output: orderid Products ----------- ----------------------- 1 100 158 234 2 125 3 101 105 212 250 or orderid Products ----------- ----------------------- 1 100|158|234 2 125 3 101|105|212|250 Thoughts or suggestions? I am using SQL Server 2k5. Example Setup: create table _orders ( OrderId int identity(1,1) primary key nonclustered ,CustomerId int ) create table _details ( DetailId int identity(1,1) primary key nonclustered ,OrderId int ,ProductId int ) insert into _orders (CustomerId) select 1 union select 2 union select 3 insert into _details (OrderId,ProductId) select 1,100 union select 1,158 union select 1,234 union select 2,125 union select 3,105 union select 3,101 union select 3,212 union select 3,250 using FOR XML PATH: select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o which outputs what I want, however is very slow for large amounts of data. One of the child tables is over 2 million rows, pushing the processing time out to ~ 4 hours. orderid Products ----------- ----------------------- 1 100 158 234 2 125 3 101 105 212 250
