  • MySQL - Selecting the top occuring entries

    - by RC
    Hi, Should be a simple one. Database is mydb. One of the columns is mydata. What SELECT query do I need in order to select the top 3 occuring results from mydata, but sorted alphabetically? For example, if my data is this: mydata ====== kilo (x 1 occurrence) lima (x 9 occurrences) golf (x 5 occurrences) echo (x 9 occurrences) zulu (x 8 occurrences) How do I get it to return "echo, lima, zulu", which are the top three frequently occurring entries sorted alphabetically? Thanks! EDIT: Just to add, they need to be distinct entries. Thanks!

  • TFS 2008 and Common libraries folder structure.

    - by Doerr
    TFS 2008 and Common Libraries I have created a Team Project called "Common Library" that will host code used in numerous different Team Projects throughout TFS. For sake of argument, lets say we have 2 distinct Librarys under the "Common Library" Team Projects, MailProject and LoggingProject. Other projects throughout TFS will be using the binary representation of these projects via branching and not the actual source code. What is the best way to set up the folder structure for this Team Project? Do I add the project to the "Common Library" and simply "include" the bin/release folder as part of the project? I have seen some examples of people creating a seperate "Deploy" folder. I assume this is synonamous with the bin/release folder?

  • conceptually different entities with a few similar properties should be stored in one table or more?

    - by Haghpanah
    Assume A and B are conceptually different entities that have a few similar properties and of course their own specific properties. In database design, should I put those two entities in one big aggregated table or two respectively designed tables. For instance, I have two types of payment; Online-payment and Manual-payment with following definition, TABLE [OnlinePayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [TrackingCode] [nvarchar](32), [ReferingCode] [nvarchar](32), [BankingAccID] [uniqueidentifier], [Status] [int], [Amount] [money], [Comments] [nvarchar](768), [CreatedAt] [datetime], [ShopingCartID] [uniqueidentifier], ) And TABLE [ManualPayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [BankingAccID] [uniqueidentifier], [BankingOrgID] [uniqueidentifier], [BranchName] [nvarchar](64), [BranchCode] [nvarchar](16), [Amount] [money], [SlipNumber] [nvarchar](64), [SlipImage] [image], [PaidAt] [datetime], [Comments] [nvarchar](768), [CreatedAt] [datetime], [IsApproved] [bit], [ApprovedByID] [uniqueidentifier], ) One of my friends told me that creating two distinct tables for such similar entities is not a well design method and they should be put in one single table for the sake of performance and ease of data manipulations. I’m now wondering what to do? What is the best practice in such a case?

  • NOT LIKE not working on comparison to a column

    - by rodling
    Data is fairly large and takes few minutes to run it every time, so its taking a lot of time debugging this problem. When I run like concat('%',T.item,'%') on smaller data it seems to identify items properly. However, when I run it on the main DB (the code shown), it still shows many(maybe even all) of the exceptions. EDIT: it seems when i add NOT it stops identifying items select distinct T.comment from (select comment, source, item from data, non_informative where ticker != "O" and source != 7 and source != 6) as T where T.comment not like concat('%',T.item,'%') order by T.comment; comment and source are in data, item is in non_informative Some items from T.item: 'Stock Analysis -', '#InsideTrades', 'IIROC Trade' Example comment which should be removed '#InsideTrades #4 | MACNAB CRAIG (Director,Officer,Chief Executive Officer): Filed Form 4 for $NNN (NATIONAL RETA' Can't seem to figure out it why shows all the items

    - by gkshope
    I'm a newbie to Android. Actually, I want to query data from Media provider with Content provider & content resolver. c = mContent.query(CONTENT_URI,projection,where,null,null); My question is, how can I query data from media provider as below using a GROUP BY clause: select DISTINCT _id, count(_id), _data FROM aaa_table WHERE _data LIKE "A" OR _data LIKE "B" GROUP BY _id; I have tried setting projection and where as follows: final String[] projection = new String[] { "_id", "COUNT ("+ _id +")" , "_data" }; and where: _data LIKE "A" OR _data LIKE "B" but, I couldn't find how to set the query option GROUP BY _id. Please help me.

  • Fetching a result twice with deferend name

    - by user1799842
    I have 1 table with tasks named opentask:columns: id,title,description,expires,creator_id,creator_name, executer_id, executer_name, priority_id, status_id1 table with users named user: with columns: user_id, username What I want is to create a query where there will be all columns from opentask table where the executer_id will be equal to the user_id of user table AND the creator_id will be equal to the user_id again. This creates a confusion because the first equality excludes the second.So I need somehow to create a query where I will include the usernames for the executer with something like where "opentask.executer_id=user_user_id" and at the same time I will include the username again (as a differend name?) for the creator with something like "where opentask.executer_id=user_user_id"So I try this, which of course I know that is missing something, can you help? SELECT DISTINCT id, title, description, expires, creator_id, executer_id, oc_opentask.priority_id, oc_opentask.status_id, priority_name, status_name, user_id, username, (SELECT username FROM oc_opentask, oc_user WHERE oc_opentask.creator_id=oc_user.user_id) AS username2 FROM oc_opentask, oc_opentask_priority, oc_user, oc_opentask_status WHERE oc_opentask.priority_id=oc_opentask_priority.priority_id AND oc_opentask.executer_id=oc_user.user_id AND oc_opentask.status_id=oc_opentask_status.status_id ORDER BY oc_opentask.expires DESC

  • Handling the distinction between undefined- and null-parameters in JavaScript

    - by Jakob
    I know very well that null and undefined are distinct in JavaScript. However, I can't seem to decide whether or not use that fact when my own functions are passed one of those as its argument. Or, expressed in a different way, should myFoo(undefined) return the same thing as myFoo(null) or is everything fine if it doesn't? Or, in yet another case, since myBar(1, 2, 3) is the same thing as myBar(1, 2, 3, undefined, undefined), should myBar(1, 2, 3, null, null) return the same thing as myBar(1, 2, 3)? I feel that there's potential for confusion in both cases and that a library should probably follow a convention when handling null/undefined. I'm not really asking for personal opinions (so please express those as comments rather than answers). I'm asking if anyone knows if there is a best practice that one should stick to when it comes to handling this distinction. References to external sources are very welcome!

  • Render multiple layers in XNA

    - by Charles
    I'm using XNA, and I've run into a little problem. I need to support multiple layers, each with a distinct z order (I call these "viewports"). A picture is worth a thousand words, so here's what it should look like: There are several things to notice here. Sprites do not render outside of their viewport, as you can see with Sprite B. Also, notice how the viewports are rendered - it's very similar to "layers" in Photoshop. Although Sprite C is has a z order of -1000, C still renders above Sprite A because its viewport's z-order is a greater than A's viewport's z-order. There's one last detail that I couldn't display very well in the above picture. Each viewport needs to optionally render a color over its region of the screen - you could think of it as a "tinting" affect. I'm completely at a loss when it comes to doing this the best way in XNA, so I could really use a short snippet of C#/VB.NET code that demonstrates this in action. Any help would be greatly appreciated.

  • SQL-Join with NULL-columns

    - by tstenner
    I'm having the following tables: Table a +-------+------------------+------+-----+ | Field | Type | Null | Key | +-------+------------------+------+-----+ | bid | int(10) unsigned | YES | | | cid | int(10) unsigned | YES | | +-------+------------------+------+-----+ Table b +-------+------------------+------+ | Field | Type | Null | +-------+------------------+------+ | bid | int(10) unsigned | NO | | cid | int(10) unsigned | NO | | data | int(10) unsigned | NO | +-------+------------------+------+ When I want to select all rows from b where there's a corresponding bid/cid-pair in a, I simply use a natural join SELECT b.* FROM b NATURAL JOIN a; and everything is fine. When a.bid or a.cid is NULL, I want to get every row where the other column matches, e.g. if a.bid is NULL, I want every row where a.cid=b.cid, if both are NULL I want every column from b. My naive solution was this: SELECT DISTINCT b.* FROM b JOIN a ON ( ISNULL(a.bid) OR a.bid=b.bid ) AND (ISNULL(a.cid) OR a.cid=b.cid ) Is there any better way to to this?

  • Confused by "let" in Clojure

    - by Tom Dalling
    I just started playing with Clojure, and I wrote a small script to help me understand some of the functions. It begins like this: (def *exprs-to-test* [ "(filter #(< % 3) '(1 2 3 4 3 2 1))" "(remove #(< % 3) '(1 2 3 4 3 2 1))" "(distinct '(1 2 3 4 3 2 1))" ]) Then it goes through *exprs-to-test*, evaluates them all, and prints the output like this: (doseq [exstr *exprs-to-test*] (do (println "===" (first (read-string exstr)) "=========================") (println "Code: " exstr) (println "Eval: " (eval (read-string exstr))) ) ) The above code is all working fine. However, (read-string exstr) is repeated so I tried to use let to eliminate the repetition like so: (doseq [exstr *exprs-to-test*] (let [ex (read-string exstr)] ( (do (println "===" (first ex) "=========================") (println "Code: " exstr) (println "Eval: " (eval ex)) ) )) ) But this works once for the first item in *exprs-to-test*, then crashes with a NullPointerException. Why is the addition of let causing the crash?

  • SQL Query taking too long

    - by user345426
    I am trying to optimize the SQL query listed below. It is basically a search engine code that retrieves products based on the products name. It also checks products model number and whether or not it is enabled. This executes in about 1.6 seconds when I run it directly through the phpMyAdmin tool but takes about 3 seconds in total to load in conjunction with the PHP file it is placed in. I need to add a category search functionality and now that is crashing the MySQL server, HELP! SELECT DISTINCT p.products_id , p.products_image , p.products_price , s.specials_new_products_price, p.products_weight , p.products_unit_quantity , pd.products_name , pd.products_img_alt , pd.products_affiliate_url FROM products AS p LEFT JOIN vendors v ON v.vendors_id = p.vendors_id LEFT JOIN specials AS s ON s.products_id = p.products_id AND s.status = 1, categories AS c , products_description AS pd , products_to_categories AS p2c WHERE ( ( pd.products_name LIKE '%cleaning%' AND pd.products_name LIKE '%supplies%' ) OR ( p.products_model LIKE '%cleaning%' AND p.products_model LIKE '%supplies%' ) OR p.products_id = 'cleaning supplies' OR v.vendors_prefix = 'cleaning supplies' OR CONCAT( CAST(v.vendors_prefix AS CHAR), '-', CAST(p.products_id AS CHAR) ) = 'cleaning supplies' ) AND p.products_status = '1' AND c.categories_status = '1' AND p.products_id = pd.products_id AND p2c.products_id = pd.products_id AND p2c.categories_id = c.categories_id ORDER BY pd.products_name

  • Widget_Controller for different types of data (MVC)

    - by steve-o
    Hello, I have a few widgets I need to show on a site - they are all relating to different types of data (e.g user, house). Each type of data and its relations is represented in specific models, but as far as a controller or helper is concerned, is it an ok plan to have a generic Widget controller/helper which generates the necessary widgets, even though each widget is dealing with distinct data? I don't really want to generate these widgets within the User and House controllers, as these controllers are dealing with different types of functionality. I'd imagine that the Widget_Controller could just contain static methods for generating these widgets, e.g: Widget_Controller::user_panel(); Does that make sense? Cheers!

  • Sqlalchemy: Many to Many relationship error

    Dear everyone, I am following the Many to many relationship described on http://www.sqlalchemy.org/docs/mappers.html#many-to-many #This is actually a VIEW tb_mapping_uGroups_uProducts = Table( 'mapping_uGroups_uProducts', metadata, Column('upID', Integer, ForeignKey('uProductsInfo.upID')), Column('ugID', Integer, ForeignKey('uGroupsInfo.ugID')) ) tb_uProducts = Table( 'uProductsInfo', metadata, Column('upID', Integer, primary_key=True) ) mapper( UnifiedProduct, tb_uProducts) tb_uGroupsInfo = Table( 'uGroupsInfo', metadata, Column('ugID', Integer, primary_key=True) ) mapper( UnifiedGroup, tb_uGroupsInfo, properties={ 'unifiedProducts': relation(UnifiedProduct, secondary=tb_mapping_uGroups_uProducts, backref="unifiedGroups") }) where the relationship between uProduct and uGroup are N:M.

  • Is it bad practice to select upstream servers based upon the HTTP method?

    - by PartlyCloudy
    I'm wondering if it is bad practice to have a reverse proxy that selects the upstream server depending on the HTTP method used? The background is that I have an abitrary web server that handles POST requests with some logic behind. The same resources also contain static content, that can be retrieved using GET. After some benchmarking I realized that nginx would handle the static content way faster than my abitrary web server doing this. I checked the option to forward incoming requests internally using nginx, which is feasible. But this would lead to the fact that different servers would serve a distinct resource, only depending on issuing a GET or POST, including different header fields.

  • Most efficient way to maintain a 'set' in SQL Server?

    - by SEVEN YEAR LIBERAL ARTS DEGREE
    I have ~2 million rows or so of data, each row with an artificial PK, and two Id fields (so: PK, ID1, ID2). I have a unique constraint (and index) on ID1+ID2. I get two sorts of updates, both with a distinct ID1 per update. 100-1000 rows of all-new data (ID1 is new) 100-1000 rows of largely, but not necessarily completely overlapping data (ID1 already exists, maybe new ID1+ID2 pairs) What's the most efficient way to maintain this 'set'? Here are the options as I see them: Delete all the rows with ID1, insert all the new rows (yikes) Query all the existing rows from the set of new data ID1+ID2, only insert the new rows Insert all the new rows, ignore inserts that trigger unique constraint violations Any thoughts?

  • Can't INSERT INTO SELECT into a table with identity column

    - by Eran Goldin
    In SQL server, I'm using a table variable and when done manipulating it I want to insert its values into a real table that has an identity column which is also the PK. The table variable I'm making has two columns; the physical table has four, the first of which is the identity column, an integer IK. The data types for the columns I want to insert are the same as the target columns' data types. INSERT INTO [dbo].[Message] ([Name], [Type]) SELECT DISTINCT [Code],[MessageType] FROM @TempTableVariable END This fails with Cannot insert duplicate key row in object 'dbo.Message' with unique index 'IX_Message_Id'. The duplicate key value is (ApplicationSelection). But when trying to insert just Values (...) it works ok. How do I get it right?

I want to create a splitview like Android gmail app (image attached). but i am not sure how to create arrow cut on the active (clicked) listview only (like shown in the image) and other listview are normal. Can someone guide me how to approach it. Sorry for confusing everyone. Updated the image with black circle. the nice inward arrow (shown under black circle) is what i am looking for. As you see this inward arrow will appear only for the active left side listview only and others will have a straight line, also left side has a distinct appearance. I want to know the approach for these using jquery mobile, jquery, css etc.

I am not able to understand how to place this big where condition (which contains a sub-query as well) in place of the "String selection" i.e. 3rd parameter of the method. Shall i simple write the entire where part(including the sub-query) as a string in the 3rd parameter or else there is some other better way for doing the same? Please suggest me the best way to do the same. Regards,
