  • C# - LINQ Statements with OR clauses

    - by user70192
    Hello, I am trying to use LINQ to return a list of tasks that are in one of three states. These states are: 10 - Completed 11 - Incomplete 12 - Skipped The state is available through a property called "TaskStateID". I can do this in LINQ with just one state as shown here: var filteredTasks = from task in tasks select task; // Do stuff with filtered tasks string selectedComboBoxValue = GetFilterComboBoxValue(); if (selected ComboBoxValue == 3) { filteredTasks = filteredTasks.Where(p => p.TaskStateID == 10); // How do I use an 'OR' here to say p.TaskStateID == 10 OR p.TaskStateID == 11 OR p.TaskStateID == 12 } As shown in the comment above, how do I use an 'OR' in a LINQ statement to say p.TaskStateID == 10 OR p.TaskStateID == 11 OR p.TaskStateID == 12? Thank you

  • CakePHP HABTM Filtering

    - by James Haigh
    Hi, I've got two tables - users and servers, and for the HABTM relationship, users_servers. Users HABTM servers and vice versa. I'm trying to find a way for Cake to select the servers that a user is assigned to. I'm trying things like $this->User->Server->find('all'); which just returns all the servers, regardless of whether they belong to the user. $this->User->Server->find('all', array('conditions' => array('Server.user_id' => 1))) just gives an unknown column SQL error. I'm sure I'm missing something obvious but just need someone to point me in the right direction. Thanks!

  • Best canvas for drawing in wxPython?

    - by Pablo Rodriguez
    I have to draw a graph of elements composing a topological model of a physical network. There would be nodes and arches, and the latter could be unidirectional or bidirectional. I would like to capture the clicking events for the nodes and the arches (to select the element and show its properties somewhere), and the dragging events for the nodes (to move them around) and arches (to connect or disconnect elements). I've done some research and I've narrowed the alternatives down to OGL (Object Graphics Library) and FloatCanvas. I would not like to go down to the DrawingContext, but it is not discarded if necessary. Which canvas option would you choose?

  • What's happening in this Perl foreach loop?

    - by benjamin button
    I have this Perl code: foreach (@tmp_cycledef) { chomp; my ($cycle_code, $close_day, $first_date) = split(/\|/, $_,3); $cycle_code =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; $close_day =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; $first_date =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; #print "$cycle_code, $close_day, $first_date\n"; $cycledef{$cycle_code} = [ $close_day, split(/-/,$first_date) ]; } The value of tmp_cycledef comes from output of an SQL query: select cycle_code,cycle_close_day,to_char(cycle_first_date,'YYYY-MM-DD') from cycle_definition d order by cycle_code; What exactly is happening inside the for loop?

  • mysql_fetch_array() not displaying all results

    - by user1666995
    I have a database with a calendar table (each row represents one day) with 4 years of rows (2012, 2013, 2014, 2015). I use the column name calyear for the year. I use the following code to find values for distinct years then display it: $year = mysql_query("SELECT DISTINCT calyear FROM calendar"); while($yeararray = mysql_fetch_array($year)) { echo($yeararray['calyear']."<br />"); } The problem is it only displays the years 2013, 2014, 2015 even though when I use echo(mysql_num_rows($year); it displays the value 4 which I take to mean all 4 years are there. I'm not quite sure where I'm going wrong with this.

  • SQL returns non-array value in PHP

    - by DeadMG
    $request = 'SELECT * FROM flight WHERE Id = \''.$_SESSION['LFLightRadio'].'\''; $data = mysql_fetch_array(mysql_query($request, $SQL)); echo '<table class="table">'; foreach($data as $key => $value) { echo '<th class="head" align="center" height="19">'.$key.'</th>'; } echo '<tr>'; foreach($data as $key => $value) { echo '<td class="cell" align="center" height="19">'.$value.'</td>'; } echo '</tr></table>'; I know that the LFlightRadio value is set, and is a value returned by the Id value of a previously returned row from the flight database. So within "flight", a record definitely exists with this Id. But, this still gives me a non-array result, so that when I try to use foreach on it, it errors out. Suggestions?

  • Getting counts of 0 from a query with a double group by

    - by Maltiriel
    I'm trying to write a query that gets the counts for a table (call it item) categorized by two different things, call them type and code. What I'm hoping for as output is the following: Type Code Count 1 A 3 1 B 0 1 C 10 2 A 0 2 B 13 2 C 2 And so forth. Both type and code are found in lookup tables, and each item can have just one type but more than one code, so there's also a pivot (aka junction or join) table for the codes. I have a query that can get this result: Type Code Count 1 A 3 1 C 10 2 B 13 2 C 2 and it looks like (with join conditions omitted): SELECT typelookup.name, codelookup.name, COUNT(item.id) FROM typelookup LEFT OUTER JOIN item JOIN itemcodepivot RIGHT OUTER JOIN codelookup GROUP BY typelookup.name, codelookup.name Is there any way to alter this query to get the results I'm looking for? This is in MySQL, if that matters. I'm not actually sure this is possible all in one query, but if it is I'd really like to know how. Thanks for any ideas.

  • Custom object based on database table

    - by Archangel
    Suppose that I have a database query which looks like below - select name, gender, birthday from person where person_id = 1; When this query is executed, some records from the database are returned. I want to make a custom object which will contain the exact attributes as the column names, with the corresponding values. As an example, suppose that the object is X. So it will have three attributes which are X.name, X.gender and X.birthday, with the corresponding values from the records. Is it doable in PHP? If so, then how?

  • COUNT issue across multiple tables

    - by Kim
    I am trying to count across 2 tables and I dont see whats wrong with my query yet I get a wrong result. User 2 does not exist in table_two, so the zero is correct. SELECT t1.creator_user_id, COUNT(t1.creator_user_id), COUNT(t2.user_id) FROM table_one AS t1 LEFT JOIN table_two AS t2 ON t2.user_id = t1.creator_user_id GROUP BY t1.creator_user_id, t2.user_id Actual result 1 192 192 2 9 0 Expected result 1 16 12 2 9 0 The result indicate a missing group by condition, but I already got both fields used. Where am I wrong ? Also, can I sum up all users that doesnt exist in table_two for t1 ? Like user 3 exists 21 times in t1, then the results would be: 1 16 12 (users with > 0 in t2 will need their own row) 2 30 0 (user 2=9 + user 3=21 => 30) Its okay for the user Id to be wrong for sum of t1 for all users with 0 in t2. If not possible, then I'll just do two queries.

  • Pagination links do not work after first page

    - by TheStack
    Hello, I am trying to fix this pagination script. It seems when I click on the pagination links [1][2][3][4]or[5] , it doesn't work. It just shows the first page and when clicking on the next numbers nothing happens. I hoping someone can see something in the script that I can not see. The main page looks like this (pagination.php): <?php include_once('generate_pagination.php'); ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" data-page="1"></div> <ul id="pagination"> <?php generate_pagination() ?> </ul> <br /> <br /> <a href="#" class="category" id="marketing">Marketing</a> <a href="#" class="category" id="automotive">Automotive</a> <a href="#" class="category" id="sports">Sports</a> Then, generate_pagination.php: <?php function generate_pagination($sql) { include_once('config.php'); $per_page = 3; //Calculating no of pages $result = mysql_query($sql); $count = mysql_fetch_row($result); $pages = ceil($count[0]/$per_page); //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li class="page_numbers" id="'.$i.'">'.$i.'</li>'; } } $ids=$_GET['ids']; generate_pagination("SELECT COUNT(*) FROM explore WHERE category='$ids'"); ?> Here is the jquery file (jquery_pagination.js): $(document).ready(function(){ //Display Loading Image function Display_Load() { $("#loading").fadeIn(900,0); $("#loading").html("<img src='bigLoader.gif' />"); } //Hide Loading Image function Hide_Load() { $("#loading").fadeOut('slow'); }; //Default Starting Page Results $("#pagination li:first").css({'color' : '#FF0084'}).css({'border' : 'none'}); Display_Load(); $("#content").load("pagination_data.php?page=1", Hide_Load()); //Pagination Click $("#pagination li").click(function(){ Display_Load(); //CSS Styles $("#pagination li") .css({'border' : 'solid #dddddd 1px'}) .css({'color' : '#0063DC'}); $(this) .css({'color' : '#FF0084'}) .css({'border' : 'none'}); //Loading Data var pageNum = this.id; $("#content").load("pagination_data.php?page=" + pageNum, function(){ Hide_Load(); $(this).attr('data-page', pageNum); }); }); // Editing below. // Sort content Marketing $("a.category").click(function() { Display_Load(); var this_id = $(this).attr('id'); $.get("pagination.php", { category: this.id }, function(data){ //Load your results into the page var pageNum = $('#content').attr('data-page'); $("#pagination").load('generate_pagination.php?category=' + pageNum +'&ids='+ this_id ); $("#content").load("filter_marketing.php?page=" + pageNum +'&id='+ this_id, Hide_Load()); }); }); }); Lastly, filter_marketing.php (when a user clicks the filter link buttons): <?php include('config.php'); $per_page = 3; if(count($_GET)>0) { if($_GET['page']!=''){ $page=$_GET['page']; } if($_GET['id']!=''){ $id=$_GET['id']; } } $page= ($_GET['page']!='') ? $_GET['page']: false; $id= ($_GET['id']!='') ? $_GET['id']: false; $start = ($page-1)*$per_page; if($page && $id){ $sql = "SELECT * FROM explore WHERE category='$id' ORDER BY category LIMIT $start,$per_page"; } else { die('Error: missing parameters.

  • Catch Id (INT AUTO INCREMENT) of a Record after INSERT INTO Statement

    - by Johannes
    This is my first time I use MySQL as datastorage for my C# Application, as I've seen that there is no UNIQUEIDENTIFIER type as in SQL server I decieded to use INT with AUTO_INCREMENT, my problem is now if I execute a INSERT, how may I get the ID of the Record I just added. My quick and dirty solution has been to execute a SELECT MAX(ID) FROM table Statement. But this doesn't seem consistent. I belive there is a better solution something like mysql_insert_id() (PHP). Any Idea how to resolve this in C#?

  • Why is this postgresql query so slow?

    - by user315975
    I'm no database expert, but I have enough knowledge to get myself into trouble, as is the case here. This query SELECT DISTINCT p.* FROM points p, areas a, contacts c WHERE ( p.latitude > 43.6511659465 AND p.latitude < 43.6711659465 AND p.longitude > -79.4677941889 AND p.longitude < -79.4477941889) AND p.resource_type = 'Contact' AND c.user_id = 6 is extremely slow. The points table has fewer than 2000 records, but it takes about 8 seconds to execute. There are indexes on the latitude and longitude columns. Removing the clause concering the resource_type and user_id make no difference. The latitude and longitude fields are both formatted as number(15,10) -- I need the precision for some calculations. There are many, many other queries in this project where points are compared, but no execution time problems. What's going on?

  • How to feed an xml database with tags obtained thru html forms ?

    - by blaise1
    Hello! Not a programmer, I begin with xml, html forms and xslt on Mac. I plan to use a form to post short texts in a xhtml page and invite end users to add some annotations to the said text. The users would select a specific part of the text posted and each annotation would stand for one specific chain of characters. My goal is to consolidate the tags obtained from various user's annotations to one xml "knowledge base" containing the original text with all the revision indicators. Then I plan to use xslt sheets to product various reports based on the tags obtained. my two questions are : 1- am I dreaming ? Is it really possible to do that with xml, xforms, xslt without using java, php, ajax or other seasoned programmer's tools ? 2- What should be my focus for further explorations aiming in that direction ? Which schema, events, sequences should I study ? Je vous remercie à l'avance, Please excuse my English. Blaise

  • MySQL Locking table from Stored FUNCTION

    - by Brandon
    I have a function in a MySQL Database that determines some sync parameters for a mobile device. The function determines the last date/time the user synchronized with the database. During my sync operation I call this server side function twice. As soon as I call it the second time - the entire Sync_Records table is locked. I cannot write to it from any other connection anywhere (note, after first call, the table is not locked). I changed the function to a Procedure - and all is fine - no locking after the second call. The entire sync operation (including both calls to the function/procedure) is within a transaction. This is an InnoDb table. The function/procedure simply does two select statements. They are storing results in local variables and then returning the date time variable. I don't understand why the tables are locked. Does anyone have any ideas?

  • jpa join query on a subclass

    - by Brian
    I have the following relationships in JPA (hibernate). Object X has two subclasses, Y and Z. Object A has a manyToOne relationship to object X. (Note, this is a one-sided relationship so object X cannot see object A). Now, I want to get the max value of a column in object A, but only where the relationship is of a specific subtype, ie...Y. So, that equates to...get the max value of column1 in object A, across all instances of A where they have a relationship with Y. Is this possible? I'm a bit lost as how to query it. I was thinking of something like: String query = "SELECT MAX(a.columnName) FROM A a join a.x; Query query = super.entityManager.createQuery(query); query.execute(); However that doesn't take account of the subclass of X...so I'm a bit lost. Any help would be much appreciated.

  • DDEX Firebird editing queries duplicates columns in Visual Studio 2008

    - by A Bothe
    Hello everybody! I don't know if some of you also has experienced it but when I edit a query in Visual Studio (it uses DDEX 2.0.5 for accessing the Firebird 2.5 database), it duplicates some of the columns. What's really interesting is the fact that only System.Boolean columns are duplicated: Originally, there was only ,for instance, a 'PRO_DELETED' field... Now I wanted to sort my results by this field - I had to change the select statement in the so-called QueryBuilder by adding "ORDER BY PRO_DELETED" ...After clicking OK it somehow created a new column (!?) called 'PRO_DELETED1' My question is: Why does DDEX add such a new row to the column view and why can't I access the original PRO_DELETED field anymore? Thanks in advance!

  • Sending files through a webservice

    - by Jay
    Hi, I have to send some files through a webservice in C#. The files to be sent can be from different locations i.e. there is one folder having 4 files and another folder having 5 files. Assuming i have a mechanism to select which files to send. What would be the best way to send those files? Should I be sending them one by one and let the client figure out how to put them together, or zip all the files into a single file and send that zip file to the client. If there is any other way to implement this, I would be more than happy to look into that approach too. Thanks

  • Control SQL Server CLR Reserved Memory

    - by Ryu
    I've recently enabled CLR on my 64 bit SQL Server 2005 machine for usage of about 3 procs. When I run the following query to gather some info on memory usage... select single_pages_kb+ multi_pages_kb + virtual_memory_committed_kb as TotalMemoryUsage, virtual_memory_reserved_kb from sys.dm_os_memory_clerks where type = 'MEMORYCLERK_SQLCLR' I get 129 mb MemoryUsage and 6.3 gb Virtual Memory Reserved The total memory of the machine is 21 gig. What does reserved virtual memory mean exactly and how can I control the size that is allocated? 6 gig is overkill for what we're doing and the memory would be much better utilized by the sproc cache. I'm concerned this reserved memory will cause swapping to the page file. Please help me take back control of the memory! Thanks
