• Combining IN and NOT IN in SQL as single result

  - by UltraVi01

  I apologize for the vague title. I am attempting to write a query that returns an alias column with matching values (resulting from an IN) as well as an alias column with values that do not match (using NOT IN). I want the result set to have: userId | matches | nonmatches. I currently have the following query which returns the matches as expected. I am having trouble getting the nonmatches in the result set -- that is, from a NOT IN statement SET @userId = 9; SELECT ug.user_id, COUNT(DISTINCT goal_id) as matches FROM user_goal ug WHERE ug.user_id!=@userId AND goal_id IN (SELECT iug.goal_id FROM user_goal iug WHERE user_id=@userId) GROUP BY user_id ORDER BY matches DESC LIMIT 4 So, the NOT IN would look something like this: goal_id NOT IN(SELECT uggg.goal_id FROM user_goal uggg WHERE user_id=@userId) AS nonmatches I am just not sure how to incorporate the NOT IN statement in my query so I get all the results

• SQL: Optimize insensive SELECTs on DateTime fields

  - by Fedyashev Nikita

  I have an application for scheduling certain events. And all these events must be reviewed after each scheduled time. So basically we have 3 tables: items(id, name) scheduled_items(id, item_id, execute_at - datetime) - item_id column has an index option. reviewed_items(id, item_id, created_at - datetime) - item_id column has an index option. So core function of the application is "give me any items(which are not yet reviewed) for the actual moment". How can I optimize this solution for speed(because it is very core business feature and not micro optimization)? I suppose that adding index to the datetime fields doesn't make any sense because the cardinality or uniqueness on that fields are very high and index won't give any(?) speed-up. Is it correct? What would you recommend? Should I try no-SQL? -- mysql -V 5.075 I use caching where it makes sence.

• SQL Convert Nvarchar(255) to DateTime problem

  - by steven

  Hi, I'm using SQL server 2008. I have 2 Tables: Table 1 and Table 2. Table 1 has 1 column called: OldDate which is nvarchar(255), null Table 2 has 1 column called: NewDate which is datetime, not null Example data in Table 1: 26/07/03 NULL NULL 23/07/2003 7/26/2003 NULL 28/07/03 When i try CAST(OldDate as datetime) I get this error: Arithmetic overflow error converting expression to data type datetime. I need to insert OldDate into NewDate with no errors. I can't skip some rows. Anyhelp would be appreciated.

• Entity Framework 4 and 0:1, 0:1 relationships

  - by Eric J.

  I'm using the Model First approach with EF 4 and hit a snag with two tables, Participant (singular because pre-existing from another app) and ActiveParticipants. A Participant may or may not be associated with exactly one ActiveParticipant and vice versa. When I create an association, everything seems to go well on the surface, but then I get a runtime error complaining that Participant does not contain the column ActiveParticipant_Id. It does contain a column ActiveParticipantId (no underscore). When I view the diagram as XML, there's a line like this: <Property Name="ActiveParticipant_Id" Type="uniqueidentifier" Nullable="true" /> Why is it adding an underscore? Is there anything special I need to do for 0:1, 0:1 relationships?

• C# Same DataSource + Multiple DataGridViews = Data Binding Issues?

  - by C. Griffin

  Here's what I'm doing: I have (2) DataGridView controls DGV #1 is bound to the DataSet, DGV #2 is bound to a DataView of the SAME DataSet Now, what I'm needing to accomplish here is this: When a user checks a boolean column on the original DGV, the second DGV should now display the newly checked row also. The context is that the first DGV is a master list, and the second one is a "favorite" view of the first. When I check the rows, the favorite column does NOT update. Do I need to use a DataAdapter to actually update the database, or can I operate directly on the DataSet (DataTable) -- or even with the Rows in the original DataGridView?

• How to Merge two databases in one in MS SQL Server 2008?

  - by SzamDev

  Hi I have 2 PCs, each one of them has MS SQL Server 2008 installed on it and there is a database with data in it. I need a way that I can move data in my DB from this MS SQL Server to another one (another PC which has the same DB) move data from one PC to another one - There is one proplem, the ID column, because each DB in my 2 PCs has data in it so this column counts from 1,2,3,....... ( data will be conflict with other data in my DB ) Is there any way to solve my proplem and move data successfully?

• Lucene case sensitive & insensitive search

  - by zvikico

  I have a Lucene index which is currently case sensitive. I want to add the option of having a case insensitive search as a fall-back. This means that results that match the case will get more weight and will appear first. For example, if the number of results is limited to 10, and there are 10 matches which match my case, this is enough. If I only found 7 results, I can add 3 more results from the case-insensitive search. My case is actually more complex, since I have items with different weights. Ideally, having a match with "wrong" case will add some weight. Needless to say, I do not want duplicate results. One possible approach is to have 2 indexes. One with case and one without and search both. Naturally, there's some redundancy here, since I need to index twice. Is there a better solution? Ideas?

• How to increase the value of a quantity field with jQuery?

  - by amir

  I have a form with some quantity field and a plus and minus sign on each side, <form id="myform"> product1 <input type="submit" value="+" id="add"> <input type="text" id="qty1"> <input type="submit value="-" id="minus"> product2 <input type="submit" value="+" id="add"> <input type="text" id="qty2"> <input type="submit value="-" id="minus"> </form> I'd like to increase the value of the field by one if the add button is pressed and decrease by one if minus is pressed. Also the value shouldn't get less than 0. Is there a way to do this in jQuery?

• How can I get a set of radio buttons to accept NULL (nothing checked)?

  - by Ethan

  I'm working on a Rails application where I have some a set of two radio buttons where users can click "yes" or "no". The MySQL DB column created by the ActiveRecord migration is a tinyint. If the user doesn't click either radio button I want MySQL to store NULL. (The column allows NULL.) And when they come back to edit the data, neither button should be checked. What's happening is that ActiveRecord is storing 0 and then when I come back the "No" button is checked. Rails 2.3.5 Form code (I'm using Haml): = f.radio_button( :model_attribute, true ) Yes = f.radio_button( :model_attribute, false ) No (In retrospect it probably would have been better to use a single checkbox, but it would be difficult to change that now.)

• Nested BooleanQuery?

  - by KailZhang

  I'm using a BooleanQuery to combine several queries. I find that if I add a BooleanQuery to the BooleanQuery, then no result is returned. The added BooleanQuery is a MUST_NOT one, like -city_id:100. But as lucene's spec says, BooleanQuery could be nested, which I think means it's okay to add such BooleanQuery. Now I have to get all clauses from the BooleanQuery to be added, and then add them to the container BooleanQuery one by one. I'm a bit confused. Anybody could help? Thank you very much!

• Windows Phone 7 Control Caching - 'Element is already the child of another element'

  - by will

  I'm trying to speed up my windows phone 7 page load times. I have a 'static' page that has a dynamically created in a Panorama control - static meaning that the content never changes. On the first load I look at my config file, create the individual PanoramaItem controls and add them to the main Panorama control. I'm trying to keep a List in a static place so that the initial creation would only happen once and I could just add a fully rendered version to my Panorama control when the page was rendered. Works fine on first load, but when I try to add the cached PanoramaItems to the Panorama control I get the message "Element is already the child of another element". This makes sense since I already added before. But I can see a way to disconnect the PanoramaItems with the first Panorama control... I could be going about the control caching thing all wrong as well... Let me know if there's another way to do this.

• MySql database design for a quiz

  - by Mark

  I'm making an online quiz with php and mysql and need a bit of help deciding how to design the database for optimal insert of questions/answers and to select questions for the quiz. The table will hold 80 questions each with 4 possible options plus the correct answer. When retrieving the questions and options from the database I will randomly select 25 questions and their options. Is it better to make a single column for all questions, options, and correct answers? For example: ID | Q | OPT1 | OPT2 | OPT3 | OPT4 | ANS Or would it be better to make a column for each individual question, option, and correct answer? For example: Q1 | Q1_OPT1 | Q1_OPT2 | Q1_OPT3 | Q1_OPT5 | Q1_ANS | Q2 | Q2_OPT1 | Q2_OPT2...

• cakephp links not relative

  - by Dan

  In my layout, I have a menu that I've included as an element, and it contains a link like so.. <? $html->link('New Part Number','/part_numbers/add'); ?> The problem that I have is that cake isn't redirecting correctly and it ends up sending me to "http://localhost/part_numbers/add" instead of "http://localhost/my_client_folder/client_app/part_numbers/add" (I'm building this locally). My cakephp app is stored a few directories below my webroot folder, but I thought cakephp would autodetect how to build the linking no matter where the application was located, right? So do i need to configure the application root folder, or create a route or something? Thanks!

• Concatenate and group multiple rows in Oracle

  - by user1693347

  Suppose I have a table like this: NAME GROUP name1 groupA name2 groupB name5 groupC name4 groupA name3 groupC I'd like to have a result like this: GROUP NAMES groupA name1,name4 groupB name2 groupC name3,name5 If there were only one column in the table, I could concatenate the records by doing the following, but with grouping in the context, I really don't have much idea. Any suggestion is welcome, thanks in advance! Concatatenating one column table: SELECT names FROM (SELECT SYS_CONNECT_BY_PATH(names,' ') names, level FROM name_table START WITH names = (SELECT names FROM name_table WHERE rownum = 1) CONNECT BY PRIOR names < names ORDER BY level DESC) WHERE rownum = 1

• Obtaining Index value of dictionary

  - by Maudise

  I have a piece of code which looks at the following public Test As Dictionary(Of String, String()) Which is brought in tester = New Dictionary(Of String, String()) tester.add("Key_EN", {"Option 1_EN", "Option 2_EN", "Option 3_EN"}) tester.add("Key_FR", {"Option 1_FR", "Option 2_FR", "Option 3_FR"}) tester.add("Key_DE", {"Option 1_DE", "Option 2_DE", "Option 3_DE"}) There's then a combo box which looks at the following dim Language as string Language = "_EN" ' note this is done by a drop down combo box to select _EN or _FR etc. cboTestBox.items.AddRange(tester("Key" & Language)) What I need to be able to do is to see what index position the answer is in and convert it back to the Key_EN. So, for example _DE is selected, then the options of "Option 1_DE", "Option 2_DE", "Option 3_DE" would be displayed. If they chose Option 3_DE then I need to be able to convert this to Option 3_EN. Many thanks Maudise

• D_WIN32_WINNT compiler warning with Boost

  - by bobber205

  Not sure what to make of this error. Added -D_WIN32_WINNT=0x0501 to Visual Studio's "Command Line" options under Project Properties but it says it doesn't recognize it and the warning still appears. I am also not sure how to add the Preprocessor Definition. :) Thanks for any help! 1Please define _WIN32_WINNT or _WIN32_WINDOWS appropriately. For example: 1- add -D_WIN32_WINNT=0x0501 to the compiler command line; or 1- add _WIN32_WINNT=0x0501 to your project's Preprocessor Definitions.

• Why is [date] + [time] non-deterministic in SQL Server 2008?

  - by John Gietzen

  I'm trying to do the following for my IIS logs table: ALTER TABLE [W3CLog] ADD [LogTime] AS [date] + ([time] - '1900-01-01') PERSISTED However, SQL Server 2008 tells me: Computed column 'LogTime' in table 'W3CLog' cannot be persisted because the column is non-deterministic. The table has this definition: CREATE TABLE [dbo].[W3CLog]( [Id] [bigint] IDENTITY(1,1) NOT NULL, ... [date] [datetime] NULL, [time] [datetime] NULL, ... ) Why is that non-deterministic? I really need to index that field. The table currently has 1598170 rows, and it is a pain to query if we can't do an index seek on the full time. Since this is being UNION'd with some other log formats, we can't very easily just use the two columns separately.

• Problem decrementing in Java with '-='

  - by hanesjw

  I'm making a scrolling game on Android and am having a hard time figuring out why the code below does not decrement past 0. Objects start at the end of the screen (so the x position is equal to the width of the screen) the objects move accross the screen by decrementing their x positions. I want them to scroll off of the screen, but when the x position hits 0, the objects just stay at 0, they do not move into the negatives. Here is my code to move objects on the screen private void incrementPositions(long delta) { float incrementor = (delta / 1000F) * Globals.MAP_SECTION_SPEED; for(Map.Entry<Integer, HashMap<Integer, MapSection>> column : scrollingMap.entrySet()) { for(Map.Entry<Integer, MapSection> row : column.getValue().entrySet()) { MapSection section = row.getValue(); section.x -= incrementor; } } } It works ok if I change section.x -= incrementor; to section.x = section.x - (int)incrementor; but if i do that the scrolling doesn't appear as smooth.
