  • UITableView Cell IndexPath

    - by Reonarudo
    Hello, Can anyone tell me how can I get a cell IndexPath? I was saving the IndexPath in the tableView: cellForRowAtIndexPath: method but this only loads when the cell is viewed and I need to know its index path on the viewDidLoad method. this resulted in a null value because as I said it only loads its value after the cell was viewed once. Thank you. EDIT The intention is being able to jump to a specific cell that has its specific number but its not linear with the sections and rows count.

  • SQL latest/top items in category

    - by drozzy
    What is a scalable way to select latest 10 items from each category. I have a schema list this: item category updated so I want to select 10 last update items from each category. The current solution I can come up with is to query for categories first and then issue some sort of union query: query = none for cat in categories: query += select top 10 from table where category=cat order by updated I am not sure how efficient this will be for bigger databases (1 million rows). If there is a way to do this in one go - that would be nice. Any help appreciated.

  • iOS 6&7: Storyboard, master detail ViewController when detailViewController is dynamic

    - by Cam
    I'm building an app for iPhone, I want to use storyboard in XCode to do a simple selection from a tableView (let's call it master table view controller with couple rows) then through navigation it goes to next page and shows a detail view for that selection. I have in my code a base class representing my detailViewController, and have 2-3 driver classes of this base class representing what I want to show in detail view controller in second page, can someone give me an idea how to set destination viewController (detailViewController) dynamically to one of my child class based on the selected row in master view controller using storyboard? Usually you assign a class to destination class in storyboard for your detail view controller with using segue, but since my destination class could be a different (child class) how you set this in storyboard? Thank you, Kam

  • Complex Join - involving date ranges and sum...

    - by calumbrodie
    I have two tables that I need to join... I want to join table1 and table2 on 'id' - however in table two id is not unique. I only want one value returned for table two, and this value represents the sum of a column called 'total_sold' - within a specified date range (say one month).. SELECT ta.id, tb.total_sold as total_sold_this_week FROM table_a as ta LEFT JOIN table_b as tb ON ta.id=tb.id AND tb.date_sold BETWEEN ADDDATE(NOW(),INTERVAL -3 WEEK) AND NOW() this works but does not SUM the rows - only returning one row for each id... how do I get the sum from table b instead of only one row??? Please criticise if format of question could use more work - I can rewrite and provide sample data if required - this is a trivialised version of a much larger problem. -Thanks

  • Scrapy Not Returning Additonal Info from Scraped Link in Item via Request Callback

    - by zoonosis
    Basically the code below scrapes the first 5 items of a table. One of the fields is another href and clicking on that href provides more info which I want to collect and add to the original item. So parse is supposed to pass the semi populated item to parse_next_page which then scrapes the next bit and should return the completed item back to parse Running the code below only returns the info collected in parse If I change the return items to return request I get a completed item with all 3 "things" but I only get 1 of the rows, not all 5. Im sure its something simple, I just can't see it. class ThingSpider(BaseSpider): name = "thing" allowed_domains = ["somepage.com"] start_urls = [ "http://www.somepage.com" ] def parse(self, response): hxs = HtmlXPathSelector(response) items = [] for x in range (1,6): item = ScrapyItem() str_selector = '//tr[@name="row{0}"]'.format(x) item['thing1'] = hxs.select(str_selector")]/a/text()').extract() item['thing2'] = hxs.select(str_selector")]/a/@href').extract() print 'hello' request = Request("www.nextpage.com", callback=self.parse_next_page,meta={'item':item}) print 'hello2' request.meta['item'] = item items.append(item) return items def parse_next_page(self, response): print 'stuff' hxs = HtmlXPathSelector(response) item = response.meta['item'] item['thing3'] = hxs.select('//div/ul/li[1]/span[2]/text()').extract() return item

  • MDX query- How do I use a member property?

    - by WaggingSiberian
    I'm a complete newb to MDX / OLAP, "data warehousing" in general. I have the following MDX query and would like my results to display the month's number (1 = January, 12 = December). Luckily, the cube creator create a member property named "Month Number Of Year" When I try to run the query, I get the following... "Query (4, 8) The function expects a tuple set expression for the 1 argument. A string or numeric expression was used." Any suggestions for fixing this? Thanks! WITH MEMBER [Measures].[Tmp] as '[Measures].[Budget] / [Measures].[Net Income]' SELECT {[Date].[Month].Properties("Month Number Of Year")} ON COLUMNS, {[Measures].[Budget],[Measures].[Net Income],[Measures].[Tmp]} ON ROWS FROM [AnalyticsCube]

  • How to get a list of unchecked checkboxes when submitting a form?

    - by SzamDev
    Hi I have this code for example : $b = ""; while ($row = mysql_fetch_array($rows)) { if ($row['enabled'] == 1) { $b = "checked"; } else { $b = "": } echo "<\input name='nam[$row[id]]' type='checkbox' value='$row[id]' $b /"; } When I execute this code, I will get a list of checkboxes, some of them are checked and others are not. I can use this code to get a list of checked checkboxes. if (isset($_POST['sub'])) { //check if form has been submitted or not $nam = $_POST['nam']; if (!empty($nam)) { foreach($nam as $k=>$val){ // proccess operation with checked checkboxes } } I need to know how I can get list of unckecked checkboxes after submitting the form. Thanks in advance.

  • Can this MySQL subquery be optimised?

    - by Dan
    I have two tables, news and news_views. Every time an article is viewed, the news id, IP address and date is recorded in news_views. I'm using a query with a subquery to fetch the most viewed titles from news, by getting the total count of views in the last 24 hours for each one. It works fine except that it takes between 5-10 seconds to run, presumably because there's hundreds of thousands of rows in news_views and it has to go through the entire table before it can finish. The query is as follows, is there any way at all it can be improved? SELECT n.title , nv.views FROM news n LEFT JOIN ( SELECT news_id , count( DISTINCT ip ) AS views FROM news_views WHERE datetime >= SUBDATE(now(), INTERVAL 24 HOUR) GROUP BY news_id ) AS nv ON nv.news_id = n.id ORDER BY views DESC LIMIT 15

  • DataView.RowFilter an ISO8601

    - by Ryan
    I have a DataTable (instance named: TimeTable) whose DefaultView (instance named: TimeTableView) I am trying to use to filter based on a date. Column clock_in contains an ISO8601 formatted string. I would like to select all the rows in this DataTable/DefaultView between 2009-10-08T08:22:02Z and 2009-10-08T20:22:02Z. What would I have to filter on this criteria? I tried: TimeTableView = TimeTable.DefaultView; TimeTableView.RowFilter = "clock_in >= #2009-10-08T08:22:02Z# and #2009-10-08T20:22:02Z#"; This is not working for me. Am I operating on the wrong object or is my filter syntax wrong?

  • correct approach to store in database

    - by John
    I'm developing an online website (using Django and Mysql). I have a Tests table and User table. I have 50 tests within the table and each user completes them at their own pace. How do I store the status of the tests in my DB? One idea that came to my mind is to create an additional column in User table. That column containing testid's separated by comma or any other delimiter. userid | username | testscompleted 1 john 1, 5, 34 2 tom 1, 10, 23, 25 Another idea was to create a seperate table to store userid and testid. So, I'll have only 2 columns but thousands of rows (no of tests * no of users) and they will always continue to increase. userid | testid 1 1 1 5 2 1 1 34 2 10

  • Accessing Textboxes in Repeater Control

    - by CccTrash
    All the ways I can think to do this seem very hackish. What is the right way to do this, or at least most common? I am retrieving a set of images from a LINQ-to-SQL query and databinding it and some other data to a repeater. I need to add a textbox to each item in the repeater that will let the user change the title of each image, very similar to Flickr. How do I access the textboxes in the repeater control and know which image that textbox belongs to? Here is what the repeater control would look like, with a submit button which would update all the image rows in Linq-to-SQL:

  • How do I do a where clause in sql and return a count back?

    - by chobo2
    Hi I am using mssql and I want to make a query that returns a count back with a where clause. Like say I have a product Table ProductId ProductName Active So how would I make it I have like Select Count(*) From Product now I don't know how to filter it so it only could if Active = true; So if there are 3 active products then it would return a count of 3 even if there is a hundred rows in the db and the other 97 are only not active. so the where clause would be probably like where active = true I am not sure how to put them together though.

  • How do I customize what a third party MSM does?

    - by sqlrob
    I'm trying to convert a project in Visual Studio 2008 from static linking of the CRT to dynamic linking. This was easy enough, and I added the CRT MSM and policy MSM to my Wix file with no problems. I am not that happy with the MSI that is output though, it is much larger than what I expected. Looking at the MSI with Orca shows three copies of the CRT DLLs that I need. From looking at the conditions, one of the sets is used for pre-XP installs. Since the system requirements are XP and later, how do I remove this component without touching the original MSM? This needs to be done in an automated build, so Orca isn't a possible solution. Plus, when I tried it with Orca, the filesize remained the same after deleting the File and Component rows. And somewhat related, how do I set the permanent attribute in the components that remain?

  • Implement keyboard control in JavaScript Grid

    - by Vanco
    I finished building a JavaScript grid control, end everything works fine. Paging, button navigation, column sorting, etc. The cells in the grid are DIVs which are generated using Mootools 1.2.4 (which is heavily used throughout the control). I want to implement keyboard control for the grid, both for paging (page up/page down) and for moving with arrow keys inside the rows/cells of the grid. I think that I have to attach an event handler on each cell of the grid and detect what key is being pressed in order to take an appropriate action. But, I can't set the focus on the cells. What am I missing? How do I do this? Any help is appreciated.

  • T-SQL: How Do I Create A "Private" Function Inside A Stored Procedure

    - by RPM1984
    Okay so im writing a SQL Server 2008 Stored Procedure (maintenance script). In doing so, being a good boy i've done plenty of error handling, checking rowcounts, printing output messages, etc But in doing this, ive found myself writing over and over again something like this: SELECT @RowsAffected = @@ROWCOUNT IF @RowsAffected > 0 BEGIN PRINT CAST(@RowsAffected, NVARCHAR(2)) + 'rows updated.' END Or debug messages like this: PRINT 'User ' + CAST(@UserId AS NVARCHAR(5)) + ' modified successfully' Is there a way i can create a kind of 'subroutine' inside the stored procedure (like a private method) that can accept something as a parameter (doesnt have to though) and do some logic? I want to be able to do something like this: CheckRowCounts Or this: PrintUserUpatedMessage(@UserId) Which would then perform the above logic (check rowcount, print message, etc) And yes obviously i can create a UDF, but then i would need to create/drop it etc as this logic is only required for the life of the execution of this stored procedure. Getting sick and tired of writing the same code over and over again, and changing all the different areas ive used it when i get an error =) Can anyone help?

  • Duplicate partitioning key performance impact

    - by Anshul
    I've read in some posts that having duplicate partitioning key can have a performance impact. I've two tables like: CREATE TABLE "Test1" ( CREATE TABLE "Test2" ( key text, key text, column1 text, name text, value text, age text, PRIMARY KEY (key, column1) ... ) PRIMARY KEY (key, name,age) ) In Test1 column1 will contain column name and value will contain its corresponding value.The main advantage of Test1 is that I can add any number of column/value pairs to it without altering the table by just providing same partitioning key each time. Now my question is how will each of these table schema's impact the read/write performance if I've millions of rows and number of columns can be upto 50 in each row. How will it impact the compaction/repair time if I'm writing duplicate entries frequently?

  • Force 'Replace Into' to use a certain index

    - by Bobby
    I have a MySQL (5.0) table with 3 rows which are considered a combined Unique Index: CREATE TABLE `test`.`table_a` ( `Id` int(11) NOT NULL AUTO_INCREMENT, `field1` varchar(5) COLLATE latin1_swedish_ci NOT NULL DEFAULT '', `field2` varchar(5) COLLATE latin1_swedish_ci NOT NULL DEFAULT '', `field3` varchar(5) COLLATE latin1_swedish_ci NOT NULL DEFAULT '', PRIMARY KEY (`Id`), INDEX `IdxUnqiue` (`field1`(5),`field2`(5),`field3`(5)) ) ENGINE=MyISAM; This table should be filled with a REPLACE INTO query: REPLACE INTO table_a ( Field1, Field2, Field3 ) VALUES ( "Test1", "Test2", "Test3" ) The behavior I'd like to see is that this query always overrides the previous inserted row, because IdxUnique is...ahm, triggered. But unfortunately, there's still the primary index which seems to kick in and always inserts a new row. What I get: Query was executed 3 times: +---Id---+---Field1---+---Field2---+---Field3---+ | 1 | Test1 | Test2 | Test2 | | 2 | Test1 | Test2 | Test2 | | 3 | Test1 | Test2 | Test2 | +--------+------------+------------+------------+ What I want: Query was executed 3 times: +---Id---+---Field1---+---Field2---+---Field3---+ | 3 | Test1 | Test2 | Test2 | +--------+------------+------------+------------+ So, can I tell REPLACE INTO to use just a certain Index or to consider one 'more inportant' then another?

  • MySQL: Storage of multiple text fields for a record

    - by Tom
    An inexperienced question: I need to store about 10 unknown-length text fields per record into a MySQL table. I expect no more than 50K rows in total for this table but speed is important. The database actions will be solely SELECTs for all practical purposes. I'm using InnoDB. In other words: id | text1 | text2 | text3 | .... | text10 As I understand that MySQL will store the text elsewhere and use its own indicators on the table itself, I'm wondering whether there's any fundamental performance implications that I should be worrying about given the way the data is stored? (i.e. several "sub-fetches" from the table). Thank you.

  • Different execution plan for similar queries

    - by Graham Clements
    I am running two very similar update queries but for a reason unknown to me they are using completely different execution plans. Normally this wouldn't be a problem but they are both updating exactly the same amount of rows but one is using an execution plan that is far inferior to the other, 4 secs vs 2 mins, when scaled up this is causing me a massive problem. The only difference between the two queries is one is using the column CLI and the other DLI. These columns are exactly the same datatype, and are both indexed exactly the same, but for the DLI query execution plan, the index is not used. Any help as to why this is happening is much appreciated. -- Query 1 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail AS b WHERE a.DLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a -- Query 2 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail b WHERE a.CLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a

  • MySQL 5.1 implicit cast from now() to a date field

    - by Savageman
    Hello, I have an issue with MySQL 5.1. A datetime data type isn't implicitly casted to match a date column. SELECT * FROM my_table WHERE my_date_field = NOW() This request doesn't return any rows using MySQL 5.1, but works well with version 5.0. If we use CURDATE() instead of NOW() it works both in MySQL 5.0 and MySQL 5.1. If the cast is explicit (CAST(NOW() AS DATE)), it also works both in MySQL 5.0 and MySQL 5.1. The problem only appears with implicit cast from datetime to date. Doesn't anyone already encountered this issue or has a clue about how to solve this problem? I know it's not the best to use NOW() instead of CURTIME(), but this isn't the question here. It is currently used in an application and the purpose is to avoid rewriting everything. Thanks!

  • Restore Emacs Session/Desktop

    - by Patrick McLaren
    I've been searching for how to restore an emacs session, with no luck. I'm looking to restore all previously open buffers, some of which might contain erc, shells, directory listings, files, etc. Every time I open emacs, I spend a considerable amount of time arranging my buffers; splitting them into rows and columns, opening a shell, arranging irc channels. It takes a while to get onto work. I've tried adding the following to my init.el (desktop-save-mode 1) And then using M-x desktop-save. This only seems to restore files that are open, not shells or anything else running within buffers. I've also checked the following questions (sorry, not able to post links yet): Session management in emacs using Desktop library Emacs session / projects / window management Emacs: reopen buffers from last session on startup? And read through: DeskTop and EmacsSession at emacswiki.org/emacs/SessionManagement Here's a screenshot example of my emacs session. A simple answer would be to just focus on real work :P

  • updating batches of data

    - by gaponte69
    I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...
