  • how to join tables sql server

    - by Rick
    Im having some trouble with joining two tables. This is what my two tables look like: Table 1 Customer_ID CustomerName Add. 1000 John Smith 1001 Mike Coles 1002 Sam Carter Table 2 Sensor_ID Location Temp CustIDFK 1000 NY 70 1002 NY 70 1000 ... ... 1001 1001 1002 Desired: Sensor_ID Location Temp CustIDFK 1000 NY 70 John Smith 1002 NY 70 Sam Carter 1000 ... ... John Smith 1001 Mike Coles 1001 1002 I have made Customer_ID from table 1 my primary key, created custIDFK in table 2 and set that as my foreign key. I am really new to sql server so I am still having trouble with the whole relationship piece of it. My goal is to match one customer_ID with one Sensor_ID. The problem is that the table 2 does not have "unique IDs" since they repeat so I cant set that to my foreign key. I know I will have to do either an inner join or outer join, I just dont know how to link the sensor id with customer one. I was thinking of giving my sensor_ID a unique ID but the data that is being inserted into table 2 is coming from another program. Any suggestions?

  • Python Macros: Use Cases?

    - by Rick Copeland
    If Python had a macro facility similar to Lisp/Scheme (something like MetaPython), how would you use it? If you are a Lisp/Scheme programmer, what sorts of things do you use macros for (other than things that have a clear syntactic parallel in Python such as a while loop)?

  • How can you tell if an HTML dropdown is displaying the list of options

    - by Ross Goddard
    Is there a way to determine if a given drop down is currently active and displaying it's list of options? I am currently binding to the mousedown event of the dropdown and populating the options when the user clicks on it. Unfortunately the mousedown event fires when the user selects the option as well. If I can determine if the drop down is already displaying it's options, then I can skip populating the options.

  • Reuse classes in an id based css

    - by C. Ross
    I have a id based CSS file where I noticed I'm mostly repeating myself. What I'd like to do is specify that an item with an id follows a certain class + some other rules. For example: I'd like id id1 to have all the properties of class LinkButton applied as well as the value back-color: green. Is there a way to do this in the css file? Is there a better way to do what I'm looking at?

  • Define variable in variable/parameter and use in javascript?

    - by Ross
    I want to defined a variable/parameter in CSS and access it by javascript. What is the best way of doing this? One option I thought of would be to place a cutsom attribute on the body element, then access that attribute via jQuery. A little more info: I'm defining colour sets in CSS. I've created a function with RaphaelJS to draw a gradient background on the page. I want this function to use a highlight colour (which is not used elsewhere on the DOM) which will be defined in the CSS along with the other colour elements. Thanks

  • MySQL FULLTEXT not working

    - by Ross
    I'm attempting to add searching support for my PHP web app using MySQL's FULLTEXT indexes. I created a test table (using the MyISAM type, with a single text field a) and entered some sample data. Now if I'm right the following query should return both those rows: SELECT * FROM test WHERE MATCH(a) AGAINST('databases') However it returns none. I've done a bit of research and I'm doing everything right as far as I can tell - the table is a MyISAM table, the FULLTEXT indexes are set. I've tried running the query from the prompt and from phpMyAdmin, with no luck. Am I missing something crucial? UPDATE: Ok, while Cody's solution worked in my test case it doesn't seem to work on my actual table: CREATE TABLE IF NOT EXISTS `uploads` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` text NOT NULL, `size` int(11) NOT NULL, `type` text NOT NULL, `alias` text NOT NULL, `md5sum` text NOT NULL, `uploaded` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ; And the data I'm using: INSERT INTO `uploads` (`id`, `name`, `size`, `type`, `alias`, `md5sum`, `uploaded`) VALUES (1, '04 Sickman.mp3', 5261182, 'audio/mp3', '1', 'df2eb6a360fbfa8e0c9893aadc2289de', '2009-07-14 16:08:02'), (2, '07 Dirt.mp3', 5056435, 'audio/mp3', '2', 'edcb873a75c94b5d0368681e4bd9ca41', '2009-07-14 16:08:08'), (3, 'header_bg2.png', 16765, 'image/png', '3', '5bc5cb5c45c7fa329dc881a8476a2af6', '2009-07-14 16:08:30'), (4, 'page_top_right2.png', 5299, 'image/png', '4', '53ea39f826b7c7aeba11060c0d8f4e81', '2009-07-14 16:08:37'), (5, 'todo.txt', 392, 'text/plain', '5', '7ee46db77d1b98b145c9a95444d8dc67', '2009-07-14 16:08:46'); The query I'm now running is: SELECT * FROM `uploads` WHERE MATCH(name) AGAINST ('header' IN BOOLEAN MODE) Which should return row 3, header_bg2.png. Instead I get another empty result set. My options for boolean searching are below: mysql> show variables like 'ft_%'; +--------------------------+----------------+ | Variable_name | Value | +--------------------------+----------------+ | ft_boolean_syntax | + -><()~*:""&| | | ft_max_word_len | 84 | | ft_min_word_len | 4 | | ft_query_expansion_limit | 20 | | ft_stopword_file | (built-in) | +--------------------------+----------------+ 5 rows in set (0.02 sec) "header" is within the word length restrictions and I doubt it's a stop word (I'm not sure how to get the list). Any ideas?

  • Draw text on a loaded pdf file with Zend Framework

    - by Rick de Graaf
    Hello, I'm trying to load a existing pdf file, and fill this with database information. Loading the file and everything is working, except for writing data to the loaded page. It doesn't write text to the loaded page. If I add a new page en use a foreach to apply drawing to all pages, all added pages are written, except for the loaded one. Below is the code I'm using: $pdf = Zend_Pdf::load('./documents/agreements/_root/gegevens.pdf'); // Load pdf $pdf->pages = array_reverse($pdf->pages); // reverse pages $pdf->pages[] = new Zend_Pdf_Page(Zend_Pdf_Page::SIZE_A4); // Add a page (A4) $font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA); // Set font foreach($pdf->pages as $page) // Apply settings+text to every page (total of 2) { $page->setFont($font, 36); $page->setAlpha(0.25); $page->drawText('LALALALALALALA', 62, 260, 'UTF-8'); } $pdf->save('./documents/agreements/Gegevens_'.$this->school_id.'.pdf'); // Save file

  • Zend_Date and Zend Locale; can't get it to work ><

    - by Rick de Graaf
    Loving Zend Framework, hating Zend_Date... I'm buidling an app where one of the functions is to track the time one spends on a certain task. This works great. My previous question was my incapability to get the sum of all the timestamps (time spent on each task). Well that works as a charm, but when I echo this value, it adds one hour. Using gmdate() (just for checking) and the value turns out exactly as it's supposed to. I thought to solve this problem easeliy with Zend_Local, but I can't get the damn thing to work! This is my bootstrap code: protected function _initLocale() { $locale = new Zend_Locale('nl_NL'); $locale->setLocale($locale); Zend_Registry::set('Zend_Locale', $locale); } This is the code in my view file: $date = new Zend_Date($this->timequery, null, $locale); echo $date->toString(Zend_Date::HOUR.':'.Zend_Date::MINUTE.':'.Zend_Date::SECOND); The timestamp I'm processing is: 2632 which equals 00:43:52. The output I get is: 01:43:52 I know the extra hour comes from the time difference, but I can seem to solve this with Zend_Local and Zend_Date.

  • Disappearing Inlineshapes

    - by Rick
    I frequently edit files that have numerous inlineshapes, one per paragraph. One of the edits I make is to eliminate "double" paragraph marks either using Search and Replace or a simple macro that performs the same operation (e.g., search for "^p^p" and replace with "^p"). This operation works fine in Word 97-2003 documents (.doc), but when I try it on .docx documents, I lose all of the inlineshapes. The .docx files seem to ignore the inlineshape, therefore seeing the paragraphs containing them as "empty". Search and Replace sees "^p^p", replaces it with "^p", and the graphic goes away. Any thoughts on how to work around this?

  • Javascript new object (function ) vs inline invocation

    - by Sheldon Ross
    Is there any considerations to determine which is better practice for creating an object with private members? var object = new function () { var private = "private variable"; return { method : function () { ..dosomething with private; } } } VS var object = function () { ... }(); Basically what is the difference between using NEW here, and just invoking the function immediately after we define it?

  • In Sphinx, can I register a bunch of keywords that should always be translated into links?

    - by Ross Rogers
    My doc strings have references to other python classes that I've defined. Every time Sphinx encounters one of these classes, I want it to insert a link to the documentation for that other class. Is this possible in Sphinx? Specifically, I have a doc string like: '''This class contains a bunch of Foo objects''' I could write: '''This class contains a bunch of :class:`~foo.Foo` objects''' but I would prefer that Sphinx finds all text matching Foo and makes it seem as though I had typed :class:~foo.Foo

  • What RESTful API would you use for a turn-based game server?

    - by Ross
    How would you model a turn-based game server as a RESTful API? For example, a chess server, where you could play a game of chess against another client of the same API. You would need some way of requesting and negotiating a game with the other client, and some way of playing the individual moves of the game. Is this a good candidate for a REST (RESTful) API? Or should this be modelled a different way?

  • Facebook like button issue.

    - by Ross Hale
    Hello community, We're having some trouble getting our like button to work. It seemed to work last week but suddenly it's stopped working. Basically when clicking "Like", we get an error saying: You failed to provide a valid list of administators. You need to supply the administors using either a "fb:app_id" meta tag, or using a "fb:admins" meta tag to specify a comma-delimited list of Facebook users. Our section looks like this: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" xml:lang="en" lang="en"> <head> <meta property="fb:app_id" content="number"/> <meta property="fb:admins" content="number"/> <meta property="og:title" content="title"/> <meta property="og:type" content="website"/> <meta property="og:url" content="url with trailing slash"/> <meta property="og:image" content="url to image"/> <meta property="og:site_name" content="Site Name"/> </head> Help?

  • What algorithm can calculate the power set of a given set?

    - by ross
    I would like to efficiently generate a unique list of combinations of numbers based on a starting list of numbers. example start list = [1,2,3,4,5] but the algorithm should work for [1,2,3...n] result = [1],[2],[3],[4],[5] [1,2],[1,3],[1,4],[1,5] [1,2,3],[1,2,4],[1,2,5] [1,3,4],[1,3,5],[1,4,5] [2,3],[2,4],[2,5] [2,3,4],[2,3,5] [3,4],[3,5] [3,4,5] [4,5] Note. I don't want duplicate combinations, although I could live with them, eg in the above example I don't really need the combination [1,3,2] because it already present as [1,2,3]

  • Rewrite query string "?x=y" style to "/x/y" style

    - by Ross
    I have a PHP MVC framework I've built from scratch which uses the traditional domain.com/controller/action URL routing. While I'm currently handling the below conversion in the router I'd like to replace them in the URL for cosmetic reasons. For example: controller/action?filter=bank Becomes: controller/action/filter/bank I've done a bit of experimentation with a regex but can't seem to find a match. I'm also not sure how to rewrite it using RewriteCond. Thanks in advance.

  • How can I allow undefined options when parsing args with Getopt

    - by Ross Rogers
    If I have a command line like: my_script.pl -foo -WHATEVER My script knows about --foo, and I want Getopt to set variable $opt_foo, but I don't know anything about -WHATEVER. How can I tell Getopt to parse out the options that I've told it about, and then get the rest of the arguments in a string variable or a list. An example: use strict; use warnings; use Getopt::Long; my $foo; GetOptions('foo' => \$foo); print 'remaining options: ', @ARGV; Then, issuing perl getopttest.pl -foo -WHATEVER gives Unknown option: whatever remaining options:

  • Installing PostgreSQL on Windows

    - by Ross
    I'm in a bit of a mess here. I installed PostgreSQL on my Vista computer a couple of days ago but then when asked to enter the password for the postgre user account I couldn't remember it (allegedly I was asked during setup but I don't remember that). Anyway, so I uninstalled Pg with the intention of reinstalling it, removed the user account, it's /Users/ directory and it's special privelleges ("Advanced user profile properties") but when I come to install Pg it seems to think the account still exists as when I supply a password during setup it says that it is not the correct password - meaning that the account still exists somewhere. Is there anyway I can recover this?
