  • My Lucene queries only ever find one hit

    - by Bob
    I'm getting started with Lucene.Net (stuck on version 2.3.1). I add sample documents with this: Dim indexWriter = New IndexWriter(indexDir, New Standard.StandardAnalyzer(), True) Dim doc = Document() doc.Add(New Field("Title", "foo", Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) doc.Add(New Field("Date", DateTime.UtcNow.ToString, Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) indexWriter.AddDocument(doc) indexWriter.Close() I search for documents matching "foo" with this: Dim searcher = New IndexSearcher(indexDir) Dim parser = New QueryParser("Title", New StandardAnalyzer()) Dim Query = parser.Parse("foo") Dim hits = searcher.Search(Query) Console.WriteLine("Number of hits = " + hits.Length.ToString) No matter how many times I run this, I only ever get one result. Any ideas?

  • How do I get a count of events each day with SQL?

    - by upl8
    I have a table that looks like this: Timestamp Event User ================ ===== ===== 1/1/2010 1:00 PM 100 John 1/1/2010 1:00 PM 103 Mark 1/2/2010 2:00 PM 100 John 1/2/2010 2:05 PM 100 Bill 1/2/2010 2:10 PM 103 Frank I want to write a query that shows the events for each day and a count for those events. Something like: Date Event EventCount ======== ===== ========== 1/1/2010 100 1 1/1/2010 103 1 1/2/2010 100 2 1/2/2010 103 1 The database is SQL Server Compact, so it doesn't support all the features of the full SQL Server. The query I have written so far is SELECT DATEADD(dd, DATEDIFF(dd, 0, Timestamp), 0) as Date, Event, Count(Event) as EventCount FROM Log GROUP BY Timestamp, Event This almost works, but EventCount is always 1. How can I get SQL Server to return the correct counts? All fields are mandatory.

  • MVC 2 in 2 Minutes!

    - by Steve Michelotti
    In a couple of recent Code Camps, I’ve given my presentation: Top 10 Ways MVC 2 Will Boost Your Productivity. In the presentation, I cover all major new features introduced in MVC 2 with a focus on productivity enhancements. To drive the point home, I conclude with a final demo where I build a couple of screens from scratch highlighting many (but not all) of the features previously covered in the talk. A couple of weeks ago, I was asked to make it available online so here it is. In 2 minutes the demo builds a couple screens from scratch that provide a goal setting tracker for a user. MVC 2 features included in the video are: Template Helpers / Editor Templates Server-side/Client-side Validation Model Metadata for View Model HTML Encoding Syntax Dependency Injection Abstract Controllers Custom T4 Templates Custom MVC Visual Studio 2010 Code Snippets The complete code samples and slide deck can be downloaded here: Top 10 Ways MVC 2 Will Boost Your Productivity.

  • Approaching SICP in Clojure instead of Scheme

    - by ironicaldiction
    I am a third year bachelor student in a software engineering program, and I brought up the idea of reading SICP to an adviser to gain a deeper and more fundamental understanding of the principles behind all this software we engineer. He suggested not to learn Scheme to complete the book (because it's not as common as modern dialects of Lisp) but to do the exercises in Clojure instead. It's an already difficult book, if I do attempt the book's exercises in the more modern Clojure, how would that work? For example, I can't find any real solutions, the syntax they teach for Scheme is different, etc.

  • mysql filtering result using left outer join

    - by user288178
    my query: SELECT content.*, activity_log.content_id FROM content LEFT JOIN activity_log ON content.id = activity_log.content_id AND sess_id = '$sess_id' WHERE activity_log.content_id IS NULL AND visibility = $visibility AND content.reported < ".REPORTED_LIMIT." AND content.file_ready = 1 LIMIT 1 The purpose of that query is to get 1 row from the content table that has not been viewed by the user (identified by session_id), but it still returns contents that have been viewed. What is wrong? ( I have checked the table making sure that the content_ids are there) Note: I think this is more efficient than using subqueries, thoughts?

  • Does approaching SICP in clojure have a high chance of success? [on hold]

    - by ironicaldiction
    I am a third year bachelor student in a software engineering program, and I brought up the idea of reading SICP to an adviser to gain a deeper and more fundamental understanding of the principles behind all this software we engineer. He suggested not to learn scheme to complete the book (because it's not as common as modern dialects of lisp) but to do the exercises in clojure instead. My worry is that completing exercises in clojure instead of scheme will make an already difficult book tortuous. If I do attempt the book's exercises in the more modern clojure, will it be difficult to succeed (for example, because I can't find any real solutions, the syntax they teach for scheme is different, etc.), or do you think approaching the book in clojure could be just as successful as approaching it in scheme? I'm really not knowledgeable enough about either clojure or scheme to make an argument about this, so I wanted to know if I should bring it up or not.

  • Grails: Querying Associations causes groovy.lang.MissingMethodException

    - by Paul
    Hi, I've got an issue with Grails where I have a test app with: class Artist { static constraints = { name() } static hasMany = [albums:Album] String name } class Album { static constraints = { name() } static hasMany = [ tracks : Track ] static belongsTo = [artist: Artist] String name } class Track { static constraints = { name() lyrics(nullable: true) } Lyrics lyrics static belongsTo = [album: Album] String name } The following query (and a more advanced, nested association query) works in the Grails Console but fails with a groovy.lang.MissingMethodException when running the app with 'run-app': def albumCriteria = tunehub.Album.createCriteria() def albumResults = albumCriteria.list { like("name", receivedAlbum) artist { like("name", receivedArtist) } // Fails here maxResults(1) } Stacktrace: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (tunehub.LyricsService$_getLyrics_closure1_closure2) values: [tunehub.LyricsService$_getLyrics_closure1_closure2@604106] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), trim() at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy:61) at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy) (...truncated...)

  • Silverlight Isolated Storage and loading big files

    - by Thomas Joulin
    In a Windows Phone 7 application, I would like to query a big XML file (list of cities) stored using Isolated Storage. If I do that this way, will the file be loaded to memory ( 5 mo) ? If so, what other solution do I have? Edit: More details. I want to use AutoCompleteBox (http://www.jeff.wilcox.name/2008/10/introducing-autocompletebox/), but instead of using a web service (this is fixed data, no need to be online), I want to query a file/database/isolated storage... I have a fixed list of cities. I said in the comments it's 40k, but it finally seems closer to 1k rows.

  • for loop with count from array, limit output? PHP

How do I get around this? My function query is as follows: function news_comments() { require_once '../data/queries.php'; // get newsID from the url $urlID = $_GET['news_id']; // run our query for newsID information $news_comments = selectQuery('*', 'news_comments', 'WHERE news_id='.$urlID.'', 'ORDER BY comment_date', 'DESC', '10'); // requires 6 params // check query for results if(!$news_comments) { // loop error session and initiate var foreach($_SESSION['errors'] as $error=>$err) { print htmlentities($err) .

  • What is use of universal character names in identifiers in C++11

    - by Jan Hudec
    The new C++ standard specifies universal character names, written as \uNNNN and \UNNNNNNNN and representing the characters with unicode codepoints NNNN/NNNNNNNN. This is useful with string literals, especially since explicitly UTF-8, UTF-16 and UCS-4 string literals are also defined. However, the universal character literals are also allowed in identifiers. What is the motivation behind that? The syntax is obviously totally unreadable, the identifiers may be mangled for the linker and it's not like there was any standard function to retrieve symbols by name anyway. So why would anybody actually use an identifier with universal character literals in it?

  • Simplicity-efficiency tradeoff

    - by sarepta
    The CTO called to inform me of a new project and in the process told me that my code is weird. He explained that my colleagues find it difficult to understand due to the overly complex, often new concepts and technologies used, which they are not familiar with. He asked me to maintain a simple code base and to think of the others that will inherit my changes. I've put considerable time into mastering LINQ and thread-safe coding. However, others don't seem to care nor are impressed by anything other than their paycheck. Do I have to keep it simple (stupid), just because others are not familiar with best practices and efficient coding? Or should I continue to do what I find best and write code my way?

  • Hibernate not using schema and catalog name in id generation with strategy increment

    - by Ben
    Hi, I am using the hibernate increment strategy to create my IDs on my entities. @GenericGenerator(name="increment-strategy", strategy="increment") @Id @GeneratedValue(generator="increment=strategy") @Column(name="HDR_ID", unique=true, nullable=false) public int getHdrId(){ return this.hdrId; } The entity has the following table annotation @Table(name = "PORDER.PUB.PO_HEADER", schema = "UVOSi", catalog = "VIRT_UVOS") Please note I have two datasources. When I try to insert an entity Hibernate creates the following SQL statement: select max(hdr_id) from PORDER.PUB.PO_HEADER which causes the following error: Group specified is ambiguous, resubmit the query by fully qualifying group name. When I create a query by hand with entityManager.createQuery() hibernate uses the fully qualified name select XXX from VIRT_UVOS.UVOSi.PORDER.PUB.PO_HEADER and that works fine. So how do I get Hibernate to use the fully qualified name in the Id autogeneration? Btw. I am using Hibernate 3.2 and Seam 2.2 running on JBoss 4.2.3 Regards Immo

  • Hbase schema design -- to make sorting easy?

    - by chen
    I have 1M words in my dictionary. Whenever a user issue a query on my website, I will see if the query contains the words in my dictionary and increment the counter corresponding to them individually. Here is the example, say if a user type in "Obama is a president" and "Obama" and "president" are in my dictionary, then I should increment the counter by 1 for "Obama" and "president". And from time to time, I want to see the top 100 words (most queried words). If I use Hbase to store the counter, what schema should I use? -- I have not come up an efficient one yet. If I use word in my dictionary as row key, and "counter" as column key, then updating counter(increment) is very efficient. But it's very hard to sort and return the top 100. Anyone can give a good advice? Thanks.

  • Gotchas INSERTing into SQLite on Android?

    - by paul.meier
    Hi friends, I'm trying to set up a simple SQLite database in Android, handling the schema via a subclass of SQLiteOpenHelper. However, when I query my tables, the columns I think I've inserted are never present. Namely, in SQLiteOpenHelper's onCreate(SQLiteDatabase db) method, I use db.execSQL() to run CREATE TABLE commands, then have tried both db.execSQL and db.insert() to run INSERT commands on the tables I've just created. This appears to run fine, but when I try to query them I always get 0 rows returned (for debugging, the queries I'm running are simple SELECT * FROM table and checking the Cursor's getCount()). Anybody run into anything like this before? These commands seem to run on command-line sqlite3. Are they're gotchas that I'm missing (e.g. INSERTS must/must not be semicolon terminated, or some issue involving multiple tables)? I've attached some of the code below. Thanks for your time, and let me know if I can clarify further. @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+ LEVEL_TABLE +" (" + " "+ _ID +" INTEGER PRIMARY KEY AUTOINCREMENT," + " level TEXT NOT NULL,"+ " rows INTEGER NOT NULL,"+ " cols INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ DYNAMICS_TABLE +" (" + " level_id INTEGER NOT NULL," + " row INTEGER NOT NULL,"+ " col INTEGER NOT NULL,"+ " type INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ SCORE_TABLE +" (" + " level_id INTEGER NOT NULL," + " score INTEGER NOT NULL,"+ " date_achieved DATE NOT NULL,"+ " name TEXT NOT NULL);"); this.enterFirstLevel(db); } And a sample of the insert code I'm currently using, which gets called in enterFirstLevel() (some values hard-coded just to get it running...): private void insertDynamic(SQLiteDatabase db, int row, int col, int type) { ContentValues values = new ContentValues(); values.put("level_id", "1"); values.put("row", Integer.toString(row)); values.put("col", Integer.toString(col)); values.put("type", Integer.toString(type)); db.insertOrThrow(DYNAMICS_TABLE, "col", values); } Finally, query code looks like this: private Cursor fetchLevelDynamics(int id) { SQLiteDatabase db = this.leveldata.getReadableDatabase(); try { String fetchQuery = "SELECT * FROM " + DYNAMICS_TABLE; String[] queryArgs = new String[0]; Cursor cursor = db.rawQuery(fetchQuery, queryArgs); Activity activity = (Activity) this.context; activity.startManagingCursor(cursor); return cursor; } finally { db.close(); } }

  • Select columns from join table only without requiring a join

    - by Kent Boogaart
    Given these tables: create table Orders ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table Items ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table OrdersItems ( OrderId INT not null, ItemId INT not null, primary key (OrderId, ItemId) ) Is it possible to use HQL/criteria API to contruct a query that results in the following SQL: SELECT [OrderId], [ItemId] FROM [OrdersItems] I've tried both of these approaches: var hqlResults = session .CreateQuery("select order.id, item.id from Order order inner join order.Items item") .List(); var criteriaResults = session .CreateCriteria<Order>() .CreateAlias("Items", "item", NHibernate.SqlCommand.JoinType.None) .SetProjection(Projections.Property("id"), Projections.Property("item.id")) .List(); But both approaches insist on generating a join (or fail because the join isn't present, in using criteria), resulting in SQL such as: select order.Id, item.Id from Orders order inner join OrdersItems ordersItems on order.Id = ordersItems.ArticleId inner join Items item on ordersItems.CategoryId = item.Id Is there any way to have NHibernate generate a query that selects columns only from the join table, without requiring a join?

  • s expression representation for c

    - by wirrbel
    Experimenting with various lisps lately (clojure especially) i have wondered if there are any s expression based representations of (subsets) of c, so you could use lisp/closure to write macros and then convert the s-expression c tree to pure c. I am not asking for a to-c-compilers of lisp/scheme/clojure but more of using lisps to transform a c syntax tree. Little background to why i am asking this question: i find myself to really enjoy certain clojure macros like the threading macros -> doto etc. And i feel that they would be great in a non FP environment as well.

  • Left Join not returning all rows

    - by DisgruntledGoat
    I have this query in MySQL: SELECT pr.*, pr7.value AS `room_price_high` FROM `jos_hp_properties` pr LEFT OUTER JOIN `jos_hp_properties2` pr7 ON pr7.property=pr.id WHERE pr7.field=23 The jos_hp_properties table has 27 rows but the query only returns one. Based on this question I think it may be because of the WHERE clause. The jos_hp_properties2 table has fields id, property, field, value, where field is a foreign key to a third table (which I don't need to get data from). Is there a way to select all the rows from the first table, including the value from table #2 where the field is 23 (or NULL if there is no field 23)?

  • Determining Connections between data in a single table

    - by user1689749
    Hi I'm a BA / programmer type doing data analysis on a legacy system. I've been teaching myself SQL to help, but I've appeared to hit upon a problem bigger than my abilities. I have two tables (generalized for simplicity): Table Objects Object_PK Table Components Component_PK Object_FK Component_Type There are 100+ distinct values in Component_Type_Code. Given that any object can have N number of Components, how can I see which Component_Type(s) appear with other Component_Type(s)? For example, the following query tells me what component_types appear with the component_type 'Component_type_1': select component_type_code, count(*) from components where object_fk in ( select object_fk from components where component_type_code = 'component_type_1' ) group by component_type_code I'd like to get a query to show me all connections My apologies for the formatting. Any help is appreciated. I've looked at cube and rollup, but didn't know how to apply to this situtation.

When I click the Aptana icon in my Unity bar nothing happens. No error pops up! I gave permission on the sh file and on the directory (/opt/Aptana_Studio_3) but still same problem. If I try executing the sh file in the /opt/Aptana_Studio_3 folder, it says "Syntax error: "(" unexpected Aptana". Also I cannot execute the Aptana binary file directly. I have been trying to solve the problem for a while now. Any help would be much appreciated. EDIT: I have Oracle Java 7 installed. I have read some post about backwards compatibility problem with Java 6 but dont know whether that's the issue. I will edit the question if I find something new.
