  • 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#?

  • Using NVL function in SQL, please help!

    - by user363024
    I'm needing to select first and last name in a table which is working fine in the following SQL, but the part that isn't working is the NVL function. The file should show all pilots at a company that fly helicopters and IF they don't have a licence the field HT_NAME should come up as 'N/A' and the field for end hours flown should be 0. I've put NVL function in as my text details but it still isn't working. Have i made a syntax error? Help would be appreciated. Select E.EMP_NBR, E.EMP_FIRSTNAME || ' ' || E.EMP_LASTNAME, E.EMP_PILOT, ED.HT_NBR, NVL(HT.HT_NAME, 'N/A'), NVL(ED.END_HRS_FLOWN, 0), ED.END_LAST_ANNUAL_REVIEW_DATE From ENDORSEMENT ED, EMPLOYEE E, HELICOPTER_TYPE HT WHERE HT.HT_NBR = ED.HT_NBR (+) ORDER BY ED.END_HRS_FLOWN DESC, E.EMP_FIRSTNAME || ' ' || E.EMP_LASTNAME ASC; should make employees who are not pilots appear with a N/A under heli type and 0 under hours flown. It isn't working - even though I have tried multiple things to repair it.

  • mySQL php query - news/ friends feed

    - by rpsep2
    I want to show a user the recent uploads from their friends. I have the users friends id's in an array: $friends A user could have, potentially, thousands of friends. I can select the uploads from 1 of a users friends with: $row = $mysqli->query("SELECT * FROM photos WHERE uploader_id = ".$friend." ORDER BY date_uploaded DESC LIMIT ".$page.", 25"); But I need to find all of a users friends uploads. I thought about doing this in a loop iterating over the $friends array, but then I'd be potentially running thousands of mysql queries. How can I do this most efficiently? so to clarify: search a 'photos' table for photos which are uploaded by specific users(friends), held in $friends variable, sort by date_uploaded and limit to x results so I can have pages 1, 2, 3 etc.

  • JTable Design Guide in Swing Application

    - by zwang
    I have a really hard design problem in my swing application. Generally Speaking, I have a JTable and a JLabel to display. The label is right below the JTable. When the height of these two components doesn't exceed a threshold, then the jtable and label displays as normal. Then height of these two components will increase as the number of records filled in the table increases. When the height of these two components exceeds a threshold, I want there is a scrollbar in the JTable and the height of these two components will be the threshold. Is this design Possible? I have draft to illustate my UI design requirement. But I don't know how to post it in this forum. And any reply are appreciate. Best Regards, Zheng.

  • 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.

  • ASP.NET MVC / Linq-to-SQL classes: Can I get it to infer readable display names?

    - by Gary McGill
    If I have a table Orders with fields CustomerID, OrderID and OrderDate, then the "Linq-to-SQL classes" generated class will be called Orders, with members called CustomerID, OrderID and OrderDate. So far so good. However, if I then do Html.LabelFor(m => m.OrderDate) then the generated text will be "OrderDate" instead of "Order Date". I tried using Order_Date as the field name, but that didn't work. Is there any way to get it to infer a better display name? [I know that I can use data annotations to specify the display name explicitly, but I really don't want to do that for all my classes/members - I just want it to work by convention.]

  • 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?

  • Stop invalid data in a attribute with foreign key constraint using triggers?

    - by Eternal Learner
    How to specify a trigger which checks if the data inserted into a tables foreign key attribute, actually exists in the references table. If it exist no action should be performed , else the trigger should delete the inserted tuple. Eg: Consider have 2 tables R(A int Primary Key) and S(B int Primary Key , A int Foreign Key References R(A) ) . I have written a trigger like this : Create Trigger DelS BEFORE INSERT ON S FOR EACH ROW BEGIN Delete FROM S where New.A <> ( Select * from R;) ); End; I am sure I am making a mistake while specifying the inner sub query within the Begin and end Blocks of the trigger. My question is how do I make such a trigger ?

  • Approach to data wrapping

    - by Mikhail
    I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

  • MS Access "#Name?" in unbound field on SOME machines

    - by alkorya
    I have a datasheet form bound to table. I added 2 unbound fields and set their Control Source properties to user defined VBA functions: 1. ConcatRelated (http://allenbrowne.com/func-concat.html) 2. Custom function that returns a string: Public Function GetLowestSatatus(LookupField As String, JSAID As Integer) As String On Error Resume Next GetLowestSatatus = DLookup(LookupField, "JsaStatuses", "ID=" & DMin("StatusID", "Tasks", "JSAID =" & JSAID)) End Function It works fine on my and some other machines but there are machines I got "#Name?" in these 2 unbound fields. All machines configured identically. Any ideas? Thank you!

  • Ideas for Quick Hierarchical Listing - .NET

    - by Robert
    I have a table in SQL Server listing corporate departments and their sections and subsections (3 levels). I would like to create some web-based listing of this, but similar to a TreeList. I was thinking to set up nested Ajax Accordions, but it was taking me way too long to put together. I would even settle for a GridView with non-repeating column values. Is there a way I can implement my idea without it taking me more than an hour or so for a newbie to complete? Any controls in ASP.NET or Ajax I can bind to would be great.

  • NHibernate: Can I access a generated primary key after saving a model?

    - by littlecharva
    Howdy, So I've got a simple table with an ID field that's incrementally generated on INSERT. I've set the mapping up in NHibernate to reflect this: <id name="ID"> <generator class="identity" /> </id> And it all works fine. Trouble is, I need to get the generated ID after I've saved a new model to use elsewhere: var model = new MyModel(); session.SaveOrUpdate(model); But at this stage model.ID == null, not the ID. Any ideas? Anthony

  • SQL IF ELSE with output params stored proc help

    - by Kettenbach
    Hi All, I have a stored proc (SS2008) that takes a couple int ids and needs to look up if they exist in a table before adding a record. I have an int output param I would like to return and set its value based on what occrured. I have this so far, but it always returns 1. Can someone point me in the right direction? BEGIN TRY IF EXISTS ( SELECT * FROM tbMap WHERE (cId= @CId) ) SET @result = -1; -- This C User is already mapped ELSE IF EXISTS ( SELECT * FROM tbMap WHERE (dId = @DId) ) SET @result = -2; -- This D User is already mapped ELSE INSERT INTO tbMap ( Login , Email , UserName , CId , DId) SELECT @UserName , usr.EmailAddress , usr.UserName , @CId , @DId FROM tbUser usr WHERE usr.iUserID = @DId SET @result = 1; RETURN END TRY What am I missing? Thanks for any tips. Cheers, ~ck in San Diego

  • copy child collection to another object

    - by Bogdan
    Hi everyone, I have a one-to-many relationship between Part and Params (a "Part" has many "Params). I'm trying to do something naive like this: Part sourcePart = em.find(Part.class, partIdSource); Part destPart = em.find(Part.class, partIdDest); Collection<Param> paramListSource = sourcePart.getParamList(); destPart.setParamList(paramListSource); Basically I want to copy all the parameters from sourcePart to destPart. Hopefully the persistence provider will automatically set the right foreign keys in the Param table/entity. The above code will obviously not work. Is there any easy way of doing this, or do I have to do create a new collection, then add each Param (creating new Param, setting attributes, etc) ?

  • What is the best way to store categorical references in SQL tables?

    - by jlafay
    I'm wanting to store a wide array of categorical data in MySQL database tables. Let's say that for instance I want to to information on "widgets" and want to categorize attributes in certain ways, i.e. shape category. For instance, the widgets could be classified as: round, square, triangular, spherical, etc. Should these categories be stored within a table to reference them best from an application? Another possibility, I would imagine, would be to add a column to widgets that contained a shape column that contained a tiny int. That way my application could search shapes by that and then use a coordinating enum type that would map the shape int meanings. Which would be best? Or is there another solution that I'm not thinking of yet?

  • Trouble with Canvas rendering in Safari/Opera

    - by Jon
    Been banging my head against this one for a while, and figured I'd turn to the experts for some advice. I've made a jQuery snippet that grabs the values from a table and plots them in a line graph on a canvas element (also generated by the JS). All's well in Firefox and Chrome, but Safari and Opera aren't displaying the plotted points. I've reviewed in Firebug, Web Inspector debugger, JSLint, and checked the markup with the w3 validator, but still can't find anything glaringly obvious. Any chance one of you guys could help me out? Here's a page with a simplified example: http://bit.ly/aAshPQ Thanks!

  • Model in sub-directory via app_label?

    - by prometheus
    In order to place my models in sub-folders I tried to use the app_label Meta field as described here. My directory structure looks like this: project apps foo models _init_.py bar_model.py In bar_model.py I define my Model like this: from django.db import models class SomeModel(models.Model): field = models.TextField() class Meta: app_label = "foo" I can successfully import the model like so: from apps.foo.models.bar_model import SomeModel However, running: ./manage.py syncdb does not create the table for the model. In verbose mode I do see, however, that the app "foo" is properly recognized (it's in INSTALLED_APPS in settings.py). Moving the model to models.py under foo does work. Is there some specific convention not documented with app_label or with the whole mechanism that prevents this model structure from being recognized by syncdb?

  • Mysql_insert_id with Doctrine

    Hi! I have a couple of tables (mySQL) that i would like to update with the help of Doctrine. The products table id is auto-incrementing, and here's a brief description on what I would like to do: $prod = new Products(); $prod->type = '0'; $categ = new CategoriesToProducts(); $categ->cat = '111'; $categ->product = $prod->id; $conn = Doctrine_Manager::connection(); $conn->flush(); How can I do this while using flush? Using a regular save is an alternative, but there will be multiple transactions while doing such. I have tried to find a Mysql_insert_id version for doctrine, but without any luck. Thanks!

  • Inheritance in kohana

    - by Binaryrespawn
    Hi all, I have recently started to use Kohana and I know inheritance is in infancy stages at the moment. The work around is using a $_has_one annotation on the child class model. In may case i have "page" as the parent of "article". I have something like, protected $_has_one = array('mypage'=>array('model'=>'page', 'foreign_key'=>'id')); In my controller, I have an action which queries the database. In this query I am trying to access fields form the parent of "article" which is the "page". $n->articles=ORM::factory('article')->where('expires','=',0) ->where('articledate','<',date('y-m-d')) ->where('expirydate','>',date('y-m-d')) ->where('mypage->status','=','PUBLISHED') ->order_by('articledate','desc') ->find_all(); The status column resides in the page table and my query is generating an error to the effect of "cannot find status", clearly because it belongs to the parent. Any ideas ?

  • Float as DateTime

    - by lp1
    SQL Server 2008 I almost have, I think, what I'm looking to do. I'm just trying to fine tune the result. I have a table that stores timestamps of all transactions that occur on the system. I'm writing a query to give an average transaction time. This is what I have so far: With TransTime AS ( select endtime-starttime AS Totaltime from transactiontime where starttime > '2010-05-12' and endtime < '2010-05-13') Select CAST(AVG(CAST(TotalTime As Float))As Datetime) from TransTime I'm getting the following result: 1900-01-01 00:00:00.007 I can't figure out how to strip the date off and just display the time, 00:00:00:007. Any help would be appreciated. Thank you.
