• Repository vs Data Access

  - by vdh_ant

  Hi guys In the context of the n-tier application, is there a difference between what you would consider your data access classes to be and your repositories? I tend to think yes but I just wanted to see what other thought. My thinking is that the job of the repository is just to contain and execute the raw query itself, where as the data access class would create the context, execute the repository (passing in the context), handle mapping the data model to the domain model and return the result back up... What do you guys think? Also do you see any of this changing in a Linq to XML scenario (assuming that you change the context for the relevant XDocument)? Cheers Anthony

• Basic Login Script using php and mysql inquiry

  - by Matt

  Attempting to write a check for a login script to see if the username is available. Would the best way to write this query be to check if isset(!_POST[]) for both values (nick and pass) then connect to database WHERE the mysql database for the usernick requested return the user id if the usernick exists evaluate if isset($id) to see if the user name is taken and use that to continue to creating an entry Does this logically sound like a method to check for login without using excessive code sorry for not posting the code, it is on another computer and this computer is locked down by my administrator at work... Also, is there another way to evaluate if a value exists in the database? For instance, instead of setting $id to the return value of the mysql database can i just ping the mysql database for the information and have it return a Boolean result so I am not putting out any user information. Thanks, Matt

• jquery calendarpicker callback pass querystring

  - by user577318

  Trying to use this CalendarPicker source and docs here: http://bugsvoice.com/applications/bugsVoice/site/test/calendarPickerDemo.jsp I need to be able to pass the date selected as query string variable of "searchdate" and reload page also updating current date for calendarPicker with querystring date on page reload. This is what I have so far: jQuery(document).ready(function() { var calendarPicker = jQuery("#calendarpicker").calendarPicker({ monthNames:["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], dayNames: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"], years:0, months:6, days:5, showDayArrows:true, callback:function(cal) { // Simple output to test calendar date change jQuery("#output").html("Selected date: " + cal.currentDate.getFullYear()+"-"+cal.currentDate.getMonth()+"-"+cal.currentDate.getDate() ); // Not working well since it also includes arrows from datepicker as selectors jQuery(".calDay").children().click(function() { window.location.href="mysite.com?searchdate="+cal.currentDate.getFullYear()+"-"+cal.currentDate.getMonth()+"-"+cal.currentDate.getDate(); }); } }); Any help greatly appreciated. Can this be done with ajax? I am attempting to update a table of events by datepicker.

• C# failing LDAP queries

  - by jpkomick

  I'm trying to access an LDAP directory via the SearchRequest object in C#. I can make the same calls via an LDAP library running in and iPhone app, as well as directly via a terminal session. However, the C# queries all seem to fail. var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=*,course=094398,class=*", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); This returns a list of terms for the course calendar. However, making the following calls won't return results for specific courses var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=1330,course=094398", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); The attributeLst object has proper attribute names included, but the query always returns with zero results. Any suggestions anyone has would be greatly appreciated. Thanks.

• Use HTTParty methods in a subclass

  - by cpjolicoeur

  I'm trying to write an API wrapper in ruby and am stumped on how I can call HTTParty methods from a subclass. For instance, I want the user to create a connection to the api and then be able to query results from subclasses. module ApiWrapper class Connection include HTTParty base_uri '...' def initialize( u, p ) ... end def contacts ApiWrapper::Contact end end end module ApiWrapper class Contact def all # issue httparty get request here that is created from the Connection class end end end ## The user would do this conn = ApiWrapper::Connection.new( 'username', 'password' ) contacts = conn.contacts.all

• 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.

• CakePHP. How can i make a model test in a table with another primary key?

  - by Marcelo

  I have this table CREATE TABLE myexamples.problems ( id INT, name VARCHAR(45) NULL , pk_id INT AUTO_INCREMENT PRIMARY KEY ); But when I try test a model in cakephp, it fails because the table has two autoincrement attributes. The following query CREATE TABLE `test_suite_problems` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(45) DEFAULT NULL, `pk_id` int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`pk_id`) ) DEFAULT CHARSET=latin1, COLLATE=latin1_swedish_ci, ENGINE=InnoDB; raise this error: "1075: Incorrect table definition; there can be only one auto column and it must be defined as a key" I have in the model class <?php class Problem extends AppModel { var $name = 'Problem'; var $displayField = 'name'; var $primaryKey='problems'; } ?> But I don't know how to make the field ID not having an autoincrement attribute, and I can't change the table structure.

• Infopath form publishing and root content type ?

  - by Steve B

  Hi, I have several infopath 2010 form template that I want to publish to a form library in SharePoint 2010 Server with enterprise CaL. All of this forms have a common part (a template part actually). Is it possible to define a common "parent" content type of this forms ? In fact, I want : Form content type (SP OOB) My root form content type, with standard columns "requester", "process name", etc. Form 1 Form 2 etc. other unrelated form 1 other unrelated form 2 Instead of the standard behavior : Form content type (SP OOB) Form 1 Form 2 other unrelated form 1 other unrelated form 2 etc. Behind this question I want to be able to create a dashboard of all form request using a content query web, by simply specifying the content type ... One last word: the idea is to allow a customer (assuming its knowledge is limited to IP 2010 basic form design). So I can't accept answers like "extract files, use a text editor and hack the xsf file"... thx in advance

• How to know the Geometry coordinates for google Maps

  - by Sam

  I found a sample script on Google Code about : Google Maps Javascript API V3 Overlays - http://code.google.com/apis/maps/documentation/javascript/overlays.html#OverlaysOverview And I want to apply this code to other countries (France, spain...) but I don't know where/how to find the Geometry code like in this script (see commented line) Here is the code: var australia = new google.maps.LatLng(-25, 133); map = new google.maps.Map(document.getElementById('map_canvas'), { center: australia, zoom: 4, mapTypeId: google.maps.MapTypeId.ROADMAP }); layer = new google.maps.FusionTablesLayer({ query: { select: 'geometry', from: '815230' // This one }, styles: [{ polygonOptions: { fillColor: "#00FF00", fillOpacity: 0.3 } }, { where: "birds > 300", polygonOptions: { fillColor: "#0000FF" } }, { where: "population > 5", polygonOptions: { fillOpacity: 1.0 } }] }); layer.setMap(map); P.S. I tried to change the google.maps.LatLng(-25, 133) to France Lat&Long but this is used only to center the map on that position. Thank you for your help

• Building highly scalable web services

  - by christopher-mccann

  My team and I are in the middle of developing an application which needs to be able to handle pretty heavy traffic. Not facebook level but in the future I would like to be able to scale to that without massive code re-writes. My thought was to modularise out everything into seperate services with their own interfaces. So for example messaging would have a messaging interface that might have send and getMessages() as methods and then the PHP web app would simply query this interface through soap or curl or something like that. The messaging application could then be any kind of application so a Java application or Python or whatever was suitable for that particular functionality with its own seperate database shard. Is this a good approach?

• Alternative databases to use when putting IIS Logs into a database using LogParser

  - by Robin Day

  We have run some scripts that use LogParser to dump our IIS logs into a SQL Server database. We can then query this to get simple stats on hits, usage etc. It's also good when linking it to error log databases and performance counter database to compare usage with errors, etc. Having implemented this for just one system and for the last 2-3 weeks we already have a 5GB database with around 10 million records. This is making any queries to this database quite slow and will no doubt cause storage issues if we continue to log as we are. Can anyone suggest any alternative databases that we could use for this data that would be more efficient for such logs? I'd be particularly interested in any experience of Google's BigTable or Amazon's SimbleDB. Are either of these suitable for reporting queries? COUNTs, GROUP BYs, PIVOTs?

• best way to get new access_token using PHP sdk

  - by randy

  I am getting the error "An active access token must be used to query information about the current user". There seems to be tons of articles and ideas, but am very confused and it seems that things are changing as well. A lot say to use offline-access but that appears to be going away. I did find this article. Does anyone have an example using the PHP SDK? I tried doing something like the below but it does not seem to work; $FBuser is still zero: $token_url = "https://graph.facebook.com/oauth/access_token?" . "client_id=" . FB_APP_ID . "&client_secret=" . FB_APP_SECRET . "&grant_type=client_credentials"; list($name, $ACCESS_TOKEN) = explode("=", file_get_contents($token_url) ); $facebook->setAccessToken(ACCESS_TOKEN); $FBuser = $facebook->getUser();

• better way to write this

  - by ash34

  Hi, I have to create a hash of the form h[:bill] = ["Billy", "NA", 20, "PROJ_A"] by login where 20 is the cumulative number of hours reported by the login for all task transactions returned by the query where each login has multiple reported transactions. Did I do this in a bad way or this seems alright. h = Hash.new Task.find_each(:include => [:user], :joins => :user, :conditions => ["from_date >= ? AND from_date <= ? AND category = ?", Date.today - 30, Date.today + 30, 'PROJ1']) do |t| h[t.login.intern] = [t.user.name, 'NA', h[t.login.intern].nil? ? (t.hrs_per_day * t.num_days) : h[t.login.intern][2] + (t.hrs_day * t.workdays), t.category] end Also if I have to aggregate not just by login but login and category how do I accomplish this? thanks, ash

• Intermittent "No Database Selected" in PHP/MySQL?

  - by ANE

  Have a PHP/MySQL form with a dropdown box containing a list of 350 names. When any random name is selected, sometimes it works & displays info about that name from the database, and sometimes the form gives the error "No Database Selected". Here's what I've tried, pretty much grasping at straws as I'm not a programmer: Increasing max_connections in /etc/my.cnf from 200 to 2000 (even though only 4-5 connections are made and it's a lightly used server) Changing mysql_pconnect to mysql_connect Adding the word true to this connection string: $mysql = mysql_pconnect($hostname_mysql, $username_mysql, $password_mysql, true) or trigger_error(mysql_error(),E_USER_ERROR); Changing the word require_once to require on this line: [?php require('/home/user/Connections/mysql.php'); ?] Enabling MySQL & PHP query & error logging. (no errors logged) Here is the code: [removed old bad code] Update: Working answer from Rob Apodaca below.

• Active Directory: User UPN or DN for NTLM name, using pure LDAP?

  - by Bernd Haug

  I have a Java app that can authenticate to LDAP by logging users into the AD LDAP server with the NTLM name (which they are used to - this is a requirement). I now also need to do authorization, and hence need to find a forest-unique identifier for the user (DN or UPN should work), from which I can further query the directory. The method needs to be absolutely portable, even if the AD is structured in an unusual fashion, otherwise I could just do a string replacement and search for a UPN of "${ntlm-user}@${ntlm-domain}.${configured-trailing-domain}" How can I do this, using pure LDAP? Currently, I'm using the java.naming.directory package, which I'd like to keep using, since it doesn't throw up problems when not binding with a DN but logging in with an NTLM name?

This may be a simple question, but I am trying to teach myself query and this has me stuck.. Any answers would be great. Thanks.

• Get all related products based on their full-text search relationship

  - by MikeJ

  I have a Product table with the fields Id, Title, Description, Keywords (just comma separated list of keywords). Table is full-text indexed. When I view one product, I do a query and search the full-text catalog for any related products based on the Keywords field. select * from Products where Contains(Products.*, @keywordsFromOneProduct) Works like a charm. Now I would like to list all products and all their related products in a big list and I want to avoid calling this method for each item. Any ideas how could I do it? I was thinking about a job that would go through products one by one and build a one-many mapping table (fields ProductId, RelatedProductId), but I wonder is there a better way?

• SQL Server CE 3.5 SP1 Stored Procedures

  - by Robert

  I have been tasked with taking an existing WinForms application and modifying it to work in an "occasionally-connected" mode. This was to be achieved with SQL Server CE 3.5 on a user's laptop and sync the server and client either via SQL Server Merge Replication or utilizing Microsoft's Sync Framework. Currently, the application connects to our SQL Server and retrieves, inserts, updates data using stored procedures. I have read that SQL Server CE does not support stored procedures. Does this mean that all my stored procedures will need to be converted to straight SQL statements, either in my code or as a query inside a tableadapter? If this is true, what are my alternatives?

• Load Balancing and Failover for Read-Only PostgreSQL Database

  - by Eric J.

  Scenario Multiple application servers host web services written in Java, running in SpringSource dm Server. To implement a new requirement, they will need to query a read-only PostgreSQL database. Issue To support redundancy, at least two PostgreSQL instances will be running. Access to PostgreSQL must be load balanced and must auto-fail over to currently running instances if an instance should go down. Auto-discovery of newly running instances is desirable but not required. Research I have reviewed the official PostgreSQL documentation on this issue. However, that focuses on the more general case of read/write access to the database. Top google results tend to lead to older newsgroup messages or dead projects such as Sequoia or DB Balancer, as well as one active project PG Pool II Question What are your real-world experiences with PG Pool II? What other simple and reliable alternatives are available?

• 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...
