• Self Assesstment Tests for Programmers

  - by THX1138.6

  I want to help the Dev team identify areas of knowledge (practical and theoretical) that they can work on. Though I am big believer in focusing on people's strengths being a good programmer requires (I think) being challenged by concepts and ideas that don't always come naturally. We work largely in the web app space using PHP & MySQL but better skills in data modelling, query optimisation, use of MVC and OOP etc. would help the team and the company a lot. I want to help the Dev team manage their careers, explore and expand their skills sets. Be all they can be and better than they were previously. I know its an idealistic goal but work must be about more than simply getting the work done. There should be some time to review, to learn, to grow and get better. Any thoughts, ideas, opinions and directions to tests or similar resources would be greatly appreciated.

• Does performance even matter anymore? [closed]

  - by Jeff Dahmer

  The performance differences between C/C++ and C# are astounding. An ASP.NET page loads in 1/8 the time that a PHP script does haha.... WPF, aka " The Future ", (you know it will be, all the companies are gonna want cool looking desktop apps, don't kid yourself.) And it has huge performance hits just to start up. We've let Microsoft make us as developers lazy! Why do I hate this, it's such a good thing? Are we at a point in time where the majority of computers can handle this kinda crap? I remember when performance used to matter. Anyways, I'm writing a .NET library and ever since I found out LINQ is slower than traditional delegates which is slower than the normal procedural code... well it's a guilty evil I feel for every LINQ query I write, because they are so beautiful. Am I just too much of a performance stickler? Or just too big of a nerd?

• Filter DataTable to show only the most recent transaction for each user

  - by Dan Neely

  I have a datatable that contains rows of transaction data for multiple users. Each row includes UserID and UserTransactionID columns. What would I use for as a RowFilter in the tables DefaultView to only show the row for each user that has the highest UserTransactionID value? sample data and results UserID UserTransactionID PassesFilter 1 1 False 1 2 False 1 3 True 2 1 True 3 1 False 3 2 True My data is orginating in a non-SQL source, the DataTable is being created to be bound to a DataGridView so I can't make changes to a query being used to get the data initially.

• Localization as an afterthought-- screwed?

  - by David

  So I signed on with a startup web development company as a subcontractor. They are putting together a large, complex user/product management system for a company that needs to support multiple levels of hierarchial localization. I signed a 3 month contract, and upon looking at their code, wish I hadn't. They opted to write their own MVC framework (I guess the client company didn't want to use a prewritten one) and it's extremely poorly written. There's SQL scattered throughout almost every model view and controller (and there's no parameter-based find methods, it's all SQL) and they haven't even THOUGHT about localization yet-- something that will have an affect on nearly EVERY query. The due date is 4 months away, and I honestly think we'd make good progress by scrapping the whole thing and going with CakePHP. Have any of you been in a similar situation, and what did you do? PS: This is written in PHP/MySQL.

• Is it possible to create a new T-SQL Operator using CLR Code in SQL Server?

  - by Eoin Campbell

  I have a very simple CLR Function for doing Regex Matching public static SqlBoolean RegExMatch(SqlString input, SqlString pattern) { if (input.IsNull || pattern.IsNull) return SqlBoolean.False; return Regex.IsMatch(input.Value, pattern.Value, RegexOptions.IgnoreCase); } It allows me to write a SQL Statement Like. SELECT * FROM dbo.table1 WHERE dbo.RegexMatch(column1, '[0-9][A-Z]') = 1 -- match entries in col1 like 1A, 2B etc... I'm just thinking it would be nice to reformulate that query so it could be called like SELECT * FROM dbo.table1 WHERE column1 REGEXLIKE '[0-9][A-Z]' Is it possible to create new comparison operators using CLR Code. (I'm guessing from my brief glance around the web that the answer is NO, but no harm asking)

• Why would you want a case sensitive database?

  - by Khorkrak

  What are some reasons for choosing a case sensitive collation over a case insensitive one? I can see perhaps a modest performance gain for the DB engine in doing string comparisons. Is that it? If your data is set to all lower or uppercase then case sensitive could be reasonable but it's a disaster if you store mixed case data and then try to query it. You have then apply a lower() function on the column so that it'll match the corresponding lower case string literal. This prevents index usage in every dbms. So wondering why anyone would use such an option.

• Free Online tools for testing mysql queries - having features like PhPMyAdmin

  - by Sandeepan Nath

  Can anybody tell me any "free online hosted database servers" (don't know if that is the correct term) where we can do query testing and all those things that we can do on tools like PhpMyAdmin? does something like that exist? Like we have http://jsfiddle.net/ for testing js codes. I checked http://sqlzoo.net/ but this is very much limited and there are some predefined tables in some given examples on which we can alter things. That's all. It does not allow me to do a lots of other things like creating tables etc. A nice resource - PhpMyAdmin's demo site . Use the latest stable version here. You have full control over the MySQL server, however you should not change root, debian-sys-maint or pma user password or limit their permissions. If you do so, demo can not be accessed until privileges are restored, so you just break things for you and other users.

• updating all other records

  - by Andrew Welch

  Hi, I've got a query below. I want to add a condition that if the parameter of @IsPrestigeFeatured = 0 then update all of the other rows < PropertyId in the IsprestigeFeatured column to 0 and if @IsPrestigeFeatured = 1 then IsprestigeFeatured = 1 where propertyId = PropertyId.

Is there something special needed for cross-frame posting?

• WordPress get_post_count?

  - by Scott B

  I'd like to create a function that retrieves the post count for a given query. I don't want to use get_posts obviously as its way to expensive for this purpose. However, that's exactly what I'm having to use in absense of a get_post_count function. My code is... global $post; $cat=get_cat_ID('mymenu'); $catHidden=get_cat_ID('hidden'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => $NumberOfPostsToShow)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2);

• MySQL - Skip Duplicate WordPress Entries

  - by 55skidoo

  I'm writing a script to display the 10 most recently "active" WordPress blog posts (i.e. those with the most recent comments). Problem is, the list has a lot of duplicates. I'd like to weed out the duplicates. Is there an easy way to do this by changing the MySQL query (like IGNORE, WHERE) or some other means? Here's what I have so far: <?php function cd_recently_active() { global $wpdb, $comments, $comment; $number = 10; //how many recently active posts to display? enter here if ( !$comments = wp_cache_get( 'recent_comments', 'widget' ) ) { $comments = $wpdb->get_results("SELECT comment_date, comment_author, comment_author_url, comment_ID, comment_post_ID, comment_content FROM $wpdb->comments WHERE comment_approved = '1' ORDER BY comment_date_gmt DESC LIMIT $number"); wp_cache_add( 'recent_comments', $comments, 'widget' ); } ?>

  I have a table with shifts history along with emp ids. I'm using this query to retrieve a list of employees and their total shifts by specifying the range to count from: SELECT ope_id, count(ope_id) FROM operator_shift WHERE ope_shift_date >=to_date( '01-MAR-10','dd-mon-yy') and ope_shift_date <= to_date('31-MAR-10','dd-mon-yy') GROUP BY OPE_ID which gives OPE_ID COUNT(OPE_ID) 1 14 2 7 3 6 4 6 5 2 6 5 7 2 8 1 9 2 10 4 10 rows selected. How do I choose the employee with the highest number of shifts under the specified range date?

• Some special characters defined in "ISO-8859-1" can't be shown when encoding with "UTF-8"

  - by Mike.Huang

  I need to get a string from URL request of brower, and then create a text image by requested text. I know the default encoding of the Java net transmission is "ISO-8859-1", it can works normally with all characters what defined in "ISO-8859-1". But when I request a multi-byte Unicode character (e.g. chinese or something like ¤?), then I need to decode it by "UTF-8" from "ISO-8859-1". My codes like: String reslut = new String(requestString.getBytes("ISO-8859-1"), "UTF-8"); Everything is fine, but I found some characters in ISO-8859-1 are not been shown now, which characters are 0x80 - 0xFF(defined in" ISO-8859-1"), i.e. the characters after 0x80 (in "ISO-8859-1") not been shown when converted to "UTF-8" from "ISO-8859-1". Any other method can solve this query?

• How do I sort in solr by term frequency in multiple fields?

  - by user1488380

  I have been assigned a task that I should change our solr search to sort a list returned by solr by using the term frequency. Well, I´ve found a way to do so simply by using omitNorms="true". The problem is, that this won´t work when I am doing a field - search, say by name: q=name:jones Following this example I get a list of document whose term frequency is the highest for the "name" field. But What I wanted to achieve is to have a query that is giving my a list of documents whose term frequency is the highest for ALL fields. Example: If a User named Jones also has the word "Jones" in his biography 10 times I want that document ranked higher. Is that possible ?

• Is it possible to implement a GC.GetAliveInstancesOf<T>() (for use in debugging)?

  - by Omer Raviv

  Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific base class. I'll emphasize that I only want to use this method during debugging, so I don't care that the GC may change an object's address in memory during runtime. One idea might be to somehow harness the !dumpheap –type command of SOS, and do some magic trick to create a temporary variable and have it point out to the memory address printed by SOS. Does anyone have a solution that works?

• Ruby on Rails ActiveRecord: eager loading issue with foreign and primary key

  - by Krishnaswamy Subramanian

  The eager loading on Ruby on Rails is not working properly for the following scenario. First we had a model called marks which has the following fields id, student, subject, mark the student is a string column which has the active directory login value, later on for reporting functionality we introduce another table called user which has the following fields id, ad_name, full_name Now on the Mark model, we have added the belongs to class belongs_to :student_details, :class_name = "User", :foreign_key = "student", :primary_key = "ad_name" and when loading using the ActiveRecord's find method we are passing in the include conditon for eager loading Marks.find(:all, :include = :reserved_user) but when the find is executed, for each and every mark a student select query executed. Is this a known bug in ROR? or am i missing something?

• How do you get average of sums in SQL (multi-level aggregation)?

  - by paxdiablo

  I have a simplified table xx as follows: rdate date rtime time rid integer rsub integer rval integer primary key on (rdate,rtime,rid,rsub) and I want to get the average (across all times) of the sums (across all ids) of the values. By way of a sample table, I have (with consecutive identical values blanked out for readability): rdate rtime rid rsub rval ------------------------------------- 2010-01-01 00.00.00 1 1 10 2 20 2 1 30 2 40 01.00.00 1 1 50 2 60 2 1 70 2 80 02.00.00 1 1 90 2 100 2010-01-02 00.00.00 1 1 999 I can get the sums I want with: select rdate,rtime,rid, sum(rval) as rsum from xx where rdate = '2010-06-01' group by rdate,rtime,rid which gives me: rdate rtime rid rsum ------------------------------- 2010-01-01 00.00.00 1 30 (10+20) 2 70 (30+40) 01.00.00 1 110 (50+60) 2 150 (70+80) 02.00.00 1 190 (90+100) as expected. Now what I want is the query that will also average those values across the time dimension, giving me: rdate rtime ravgsum ---------------------------- 2010-01-01 00.00.00 50 ((30+70)/2) 01.00.00 130 ((110+150)/2) 02.00.00 190 ((190)/1) I'm using DB2 for z/OS but I'd prefer standard SQL if possible.

• Kendo UI, searchable Combobox

  - by user2083524

  I am using the free Kendo UI Core Framework. I am looking for a searchable Combobox that fires the sql after inserting, for example, 2 letters. Behind my Listbox there are more than 10000 items and now it takes too much time when I load or refresh the page. Is it possible to trigger the sql query only by user input like the autocomplete widget do? My code is: <link href="test/styles/kendo.common.min.css" rel="stylesheet" /> <link href="test/styles/kendo.default.min.css" rel="stylesheet" /> <script src="test/js/jquery.min.js"></script> <script src="test/js/kendo.ui.core.min.js"></script> <script> $(document).ready(function() { var objekte = $("#objekte").kendoComboBox({ placeholder: "Objekt auswählen", dataTextField: "kurzname", dataValueField: "objekt_id", minLength: 2, delay: 0, dataSource: new kendo.data.DataSource({ transport: { read: "test/objects.php" }, schema: { data: "data" } }), }).data("kendoComboBox"); </script>

• How to build an interactive search engine web interface using python

  - by asmaier

  I have build a static web interface for searching data from some tables in my PostgreSQL database. The query website consists of a simple textfield for entering the search term, the result website presents the results as a simple html table. The server side code for searching the PostgreSQL database and returning the results is written in python using psycopg2. Now I would like to add some interactive "Ajax features" to my search engine. When entering the search term I would like to be able to see a list of possible search terms like Google does it. On the results page, I would like to be able to sort the table showing the results. What would be the easiest/recommended way to implement these features for my search engine web site? Do I need a full-fledged web framework like Django for that?

• Optimize SQL with Interbase

  - by Roland Bengtsson

  I was inspired by the good answers from my previous question about SQL. Now this SQL is run on a DB with Interbase 2009. It is about 21 GB in size. SELECT DistanceAsMeters, Bold_Id, Created, AddressFrom.CityName_CO as FromCity, AddressTo.CityName_CO as ToCity FROM AddrDistance LEFT JOIN Address AddressFrom ON AddrDistance.FromAddress = AddressFrom.Bold_Id LEFT JOIN Address AddressTo ON AddrDistance.ToAddress = AddressTo.Bold_Id Where DistanceAsMeters = 0 and PseudoDistanceAsCostKm = 0 and not AddrDistance.bold_id in (select bold_id from DistanceQueryTask) Order By Created Desc There are 840000 rows with AddrDistance 190000 rows with Address and 4 with DistanceQueryTask. The question is, can this be done faster? I guess, the same query is run many times select bold_id from DistanceQueryTask. Note that I'm not interested in stored procedures, just plain SQL :)
