  • Search a string to find which records in table are inside said string

    - by Improfane
    Hello, Say I have a string. Then I have a number of unique tokens or keywords, potentially a large number in a database. I want to search and find out which of these database strings are inside the string I provide (and get the IDs of them). Is there a way of using a query to search the provided string or must it be taken to application space? Am I right in thinking that this is not a 'full text search'? Would the best method be to insert it into the database to make it a full text search?

  • getting the Contact's Birthday of a HTC Sense phone

    - by Pentium10
    I am not sure, but probably HTC Sense does the following, syncs my Facebook contacts to my phone along with their mobile number and their birthday. This shows well in the agenda and the user panel. But as it turns out it doesn't use the standard SDK way to store the birthdays. As if I use the following code to get the birthday of a contact it returns NO data for those contacts. public String getBirthday() { if (data.containsKey(BIRTHDAY)) { return CRUtils.getString(data, BIRTHDAY); } else { // read birthday Cursor c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + this.getId() + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, null); if (c != null) { try { if (c.moveToFirst()) { String s = c.getString(0); this.setBirthday(s); return s; } } finally { c.close(); } } return ""; } } How can I fix this?

  • Favoriting system on Appengine

    - by Mateusz Cieslak
    Hi, I have the following model structure class Authors(db.Model) : nickname = db.StringProperty(required=True) fullname = db.StringProperty(required=True) class Articles(db.Model) : title = db.StringProperty(required=True) body = db.StringProperty(required=True) author = db.ReferenceProperty(Authors, required=True) class Favorites(db.Model) : who = db.ReferenceProperty(Authors, required=True) what = db.ReferenceProperty(Articles, required=True) I'd like to display 10 last articles according to this pattern: article.title, article.body, article.author(nickname), info if this article has been already favorited by the signed in user. I have added a function which I use to get the authors of these articles using only one query (it is described here) But I don't know what to do with the favorites (I'd like to know which of the displayed articles have been favorited by me using less than 10 queries (I want to display 10 articles)). Is it possible?

  • hibernate not throwing stale state exception nor it is overwriting data

    - by Reddy
    Our application do the following. 1. Start the transaction. 2. Execute a query using prepared statement 3. Check a condition to see the number of rows updated are equal to the required number. 4. It commits on success of above condition otherwise it will roll back However the problem is that when two threads are simultaneously enter this code. Thread-1 is updating a row in step 2. It checked the condition and committed successfully since the condition is successful. Thread-2 started execution somewhere between steps 1 & 4, and it is failing on at condition checking at step 3 (as it is getting number of updated rows as 0). I expected second thread to throw an exception but it is not. What could be the problem?

  • How to import and export only data of whole database in access 2007

    - by DiegoMaK
    Hi, I have two identical databases with same structure, database a in computer a and database b in computer b. The data of database a*(a.accdb)* and database b*(b.accdb)* are different. then in database a i have for example ID:1, 2, 3 and in database B i Have ID:4,5,6 Then i need merge these databases data in only one database(a or b, doesn't matter) so the final database looks like. ID:1,2,3,4,5,6 I search an easy way to do this. because i have many tables. and do this by union query is so tedious. I search for example for a backup option for only data without scheme as in postgreSQl or many others RDBMS, but i don't see this options in access 2007. pd:only just table could be duplicate values(i guess that pk doesn't allow copy a duplicate value and all others values will be copied well). if i wrong please correct me. thanks for your help.

  • Business Objects Web Intelligence-style reporting in a Winform app. Is this possible?

    - by George
    I have a WinForm app that displays results in a Gridview control. If a user right mouse clicks on a row, he can then, from a popup menu, select a command to perform on the row much like windows File Explorer. But now I want to be able to give the user the ability to construct a filter so that he can control which rows are displayed in the grid w/o effecting the functionality of the application. I would also like the user to be able to select the columns/fields that he sees in the grid. For the basis of this question, let's assume that the data displayed in grid comes from a single table. business Objects' Web Intelligence and Desktop Intelligence applications give me very flexible and powerful reporting capabilities, but I want to integrate this capability into my WinForm application. Does Business Objects, or maybe Crystal Reports provide this sort of functionality? I can construct my own query builder but I'd rather not reinvent sliced bread.

  • SQL Server Error: maximum number of prefixes. The maximum is 3.

    - by Ian Boyd
    Trying to run a cross-server update: UPDATE cmslive.CMSFintrac.dbo.lsipos SET PostHistorySequencenNmber = ( SELECT TransactionNumber FROM Transactions WHERE Transactions.TransactionDate = cmslive.CMSFintrac.dbo.lsipos.TransactionDate) Gives the error: Server: Msg 117, Level 15, State 2, Line 5 The number name 'cmslive.CMSFintrac.dbo.lsipos' contains more than the maximum number of prefixes. The maximum is 3. What gives? Note: Rearranging the query into a less readable join form: UPDATE cmslive.CMSFintrac.dbo.lsipos SET PostHistorySequenceNumber = B.TransactionNumber FROM cmslive.CMSFintrac.dbo.lsipos A INNER JOIN Transactions B ON A.TransactionDate = B.TransactionDate does not give an error.

  • Decoupling into DAL and BLL - my concerns.

    - by novice_man
    Hi, In many posts concerning this topic I come across very simple examples that do not answer my question. Let's say a have a document table and user table. In DAL written in ADO.NET i have a method to retries all documents for some criteria. Now I the UI I have a case where I need to show this list along with the names of the creator. Up to know I have it done with one method in DAL containig JOIN statement. However eveytime I have such a complex method i have to do custom mapping to some object that doesn't mark 1:1 to DB. Should it be put into another layer ? If so then I will have to resing from join query for iteration through results and querying each document author. . . which doen't make sense... (performance) what is the best approach for such scenarios ?

  • MySQL: Count occurrences of known (or enumerated) distinct values

    - by Eilidh
    After looking at how to count the occurrences of distinct values in a field, I am wondering how to count the occurrences of each distinct value if the distinct values are known (or enumerated). For example, if I have a simple table - TrafficLight Colour ------------ ------ 1 Red 2 Amber 3 Red 4 Red 5 Green 6 Green where one column (in this case Colour) has known (or enumerated) distinct values, how could I return the count for each colour as a separate value, rather than as an array, as in the linked example. To return an array with a count of each colour (using the same method as in the linked example), the query would be something like SELECT Colour COUNT(*) AS ColourCount FROM TrafficLights GROUP BY Colour, and return an array - Colour ColourCount ------ ----------- Red 3 Amber 1 Green 2 What I would like to do is to return the count for each Colour AS a separate total (e.g. RedCount). How can I do this?

  • Passing URIs as URL arguments in Drupal

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • Find Elements by Attribute using XDocument

    This query seems to be valid, but I have 0 results. IEnumerable<XElement> users = (from el in XMLDoc.Elements("Users") where (string)el.Attribute("GUID") == userGUID.ToString() select el); My XML is as follows: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <Users> <User GUID="68327fe2-d6f0-403b-a7b6-51860fbf0b2f"> <Key ID="F7000012ECEAD101"> ... </Key> </User> </Users> Do you have any clues to shed some light onto this?

  • Advantage Data Architect doesn't accept 'output to', are there any other options for outputting a ta

    - by likesalmon
    I'm trying to output the results of a SELECT query to a tab delimited text file in Advantage Data Architect. I know I can use the 'Export to' feature to do this, but there are a lot of tables and that is going to take forever. I would rather use the SQL editor, but I found out it does not accept the OUTPUT TO argument, even though that command is part of Sybase SQL. I would like to do this: SELECT * FROM tablename; OUTPUT TO 'C:/ExportDirectory' DELIMITED BY '\t' FORMAT TEXT; Is there another way?

  • Echo mysql results in a loop?

    - by Roy D. Porter
    I am using turn.js to make a book. Every div within the 'deathnote' div becomes a new page. <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page </div> //ends book What I am doing is trying to get 3 'content' (content being a name and cause of death) divs onto 1 page, and then generate a new page. So here is what i want: <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"> //creates new page but leaves it open <div> CONTENT </div> <div> CONTENT </div> <div> CONTENT </div> </div> //ends the page </div> //ends book Seems simple enough, however the content is data from a MySQL DB, so i have to echo it in using PHP. Here is what i have so far <div id="deathnote"> <div style="background-image:url(images/coverpage.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <?php $pagecount = 0; $db = new mysqli('localhost', 'username', 'passw', 'DB'); if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error .

  • Avoiding dog-piling or thundering herd in a memcached expiration scenario

    - by Quintin Par
    I have the result of a query that is very expensive. It is the join of several tables and a map reduce job. This is cached in memcached for 15 minutes. Once the cache expires the queries are obviously run and the cache warmed again. But at the point of expiration the thundering herd problem issue can happen. One way to fix this problem, that I do right now is to run a scheduled task that kicks in the 14th minute. But somehow this looks very sub optimal to me. Another approach I like is nginx’s proxy_cache_use_stale updating; mechanism. The webserver/machine continues to deliver stale cache while a thread kicks in the moment expiration happens and updates the cache. Has someone applied this to memcached scenario though I understand this is a client side strategy? If it benefits, I use Django.

  • How do I list all non-system stored procedures?

    - by bubbassauro
    I want to create a query to list of all user defined stored procedures, excluding the ones that are system stored procedures, considering that: Checking the name like "sp_" doesn't work because there are user stored procedures that start with "sp_". Checking the property is_ms_shipped doesn't work because there are system stored procedures that have that flag = 0, for example: sp_alterdiagram (it is not MSShipped but appears under System Stored Procedures in SQL Server Management Studio). There must be a property, or a flag somewhere since you can see the "System Stored Procedures" in a separate folder in SQL 2005. Does anyone know? Edit: A combination of the suggestions below worked for me: select * from sys.objects O LEFT OUTER JOIN sys.extended_properties E ON O.object_id = E.major_id WHERE O.name IS NOT NULL AND ISNULL(O.is_ms_shipped, 0) = 0 AND ISNULL(E.name, '') <> 'microsoft_database_tools_support' AND O.type_desc = 'SQL_STORED_PROCEDURE' ORDER BY O.name

  • Regex for finding valid sphinx fields

    - by mlissner
    I'm trying to validate that the fields given to sphinx are valid, but I'm having difficulty. Imagine that valid fields are cat, mouse, dog, puppy. Valid searches would then be: @cat search terms @(cat) search terms @(cat, dog) search term @cat searchterm1 @dog searchterm2 @(cat, dog) searchterm1 @mouse searchterm2 So, I want to use a regular expression to find terms such as cat, dog, mouse in the above examples, and check them against a list of valid terms. Thus, a query such as: @(goat) Would produce an error because goat is not a valid term. I've gotten so that I can find simple queries such as @cat with this regex: (?:@)([^( ]*) But I can't figure out how to find the rest. I'm using python & django, for what that's worth.

  • NHibernate - get List<long> representing primary keys?

    - by Nathan
    I have a situation where I definitely don't want to get the whole domain object. Basically, the entity has a primary key of long (.NET)/bigint(sql server 2005). I simply need to pass the primary key to an external system which will access the database directly - and since the list of ids could be large, I don't want to rehydrate the entire domain object just to get the Id. In linq2sql, I could accomplish this with a projection, but I am restricted to NHibernate 1.2.1.4000, which doesn't support Linq. Is there a way to accomplish this using NHibernate 1.2.1.4000? (I am open to using a named-query if that will work)

  • How to query_posts after the current timestamp and sort reverse chronologically?

    I am using the following code in Wordpress to query events (custom post type) and order them by date chronologically.. query_posts( array( 'post_type' => 'events', 'showposts' => 10, 'orderby' => 'meta_value_num','meta_key' => '_ecmb_datetime' ) ); Where the meta key _ecmb_datetime is, this is the timestamp of the event. I don't want to show events that have already happened, so my question is how do I only show events happening after my current time, and how do I sort reverse chronologically? Any help is greatly appreciated

  • How to integrate access control with my ORM in a .net windows form application?

    - by Ying
    I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.

  • C# mysqlreader on same connection error

    - by dominiquel
    Hi, I must find a way to do this in C#, if possible... I must loop on my folder list (mysql table), and for each folder I instanciate I must do another query, but when I do this it says : "There is already an open DataReader associated with this Connection" and I am inside a mysqlreader loop already. Note that I have oversimplified the code just to show you, the fact is that I must do queries inside a mysqlreader loop, and it looks to be impossible as they are on the same connection? MySqlConnection cnx = new MySqlConnection(connexionString); cnx.Open(); MySqlCommand command= new MySqlCommand("SELECT * FROM folder WHERE folder_id = " + id, cnx); MySqlDataReader reader= commande.ExecuteReader(); while (reader.Read()) { this.folderList[this.folderList.Length] = new CFolder(reader.GetInt32"folder_id"), cnx); } reader.Close(); cnx.Close();

  • Updating rows using "in" operator in "where" clause

    - by doublep
    Hi. I stumbled upon SQL behavior I don't understand. I needed to update several rows in a table at once; started with just finding them: SELECT * FROM some_table WHERE field1 IN (SELECT ...) This returned a selection of about 60 rows. Now I was pretty confident I got the subquery right, so I modified the first part only: UPDATE some_table SET field2 = some_value WHERE field1 IN (SELECT ...) In other words, this was exactly as the first query after the WHERE. However, it resulted in 0 rows updated, whereas I would expect those 60. Note that the statement above would change field2, i.e. I verified that some_value was not present in the selected rows. The subquery was a modestly complicated SQL piece with 2 (different) tables, 1 view, joins and its own WHERE clause. In case this matters, it happened with Oracle Database 10g. So, the question is, why UPDATE didn't touch the rows returned by SELECT?
