• Specify default group and permissions for new files in a certain directory

  - by mislav

  I have a certain directory in which there is a project shared by multiple users. These users use SSH to gain access to this directory and modify/create files. This project should only be writeable to a certain group of users: lets call it "mygroup". During an SSH session, all files/directories created by the current user should by default be owned by group "mygroup" and have group-writeable permissions. I can solve the permissions problem with umask: $ cd project $ umask 002 $ touch test.txt File "test.txt" is now group-writeable, but still belongs to my default group ("mislav", same as my username) and not to "mygroup". I can chgrp recursively to set the desired group, but I wanted to know is there a way to set some group implicitly like umask changes default permissions during a session. This specific directory is a shared git repo with a working copy and I want git checkout and git reset operations to set the correct mask and group for new files created in the working copy. The OS is Ubuntu Linux. Update: a colleague suggests I should look into getfacl/setfacl of POSIX ACL but the solution below combined with umask 002 in the current session is good enough for me and is much more simple.

• SQL where clause to work with Group by clause after performing a count()

  - by Matt

  Tried my usual references at w3schools and google. No luck I'm trying to produce the following results. QTY is a derived column | Position | QTY -------------------- 1 Clerk 2 2 Mgr 2 Here's what I'm not having luck with: SELECT Position, Count(position) AS 'QTY' FROM tblemployee Where ('QTY' != 1) GROUP BY Position I know that my Position is set up as varchar(255) Count produces a integer data and my where clasue is accurate so that leads me to believe that that Count() is jamming me up. Please throw up an example so I can reference later. Thanks for the help!

• Adding to the browser user agent string?

  - by stwissel

  I have a plug-in that handles its own url schema (something like mystuf:// ). If a user clicks on such a link when the plug-in isn't installed (s)he gets an ugly error. So I extended my installer to write into the Registry (for Internet Explorer) and the user.js (for Firefox) to ADD a custom string to the user agent string. These additions survive a browser upgrade nicely (Microsoft uses this technique to indicate the presence of the dotNet Framework). Now I need to extend this to Apple Safari and Google Chrome on all supported platforms. To be clear: I'm not looking how to REPLACE the user agent string, but how to amend it with additional information. Any hint?

• Why might SQL execute more quickly on SQL Server 2000 when NOT using a stored procedure?

  - by Kofi Sarfo

  I could see nothing wrong with the execution plan. Besides, as I understand it, SQL Server 2000 extended many of the performance benefits of stored procedures to all SQL statements by recognising new T-SQL statements against T-SQL statements of existing execution plans (by retaining execution plans for all SQL statements in the procedure cache, not just stored procedure execution plans) It's a fairly straight forward SELECT statement with sensible table joins, no transactions included or linked servers being referenced within the query and WITH (NOLOCK) table hints applied. The stored procedure was created by dbo and the user has all the necessary permissions. So my question is this: What are the likely reasons for a query to take only a few seconds to run but then take several minutes when identical T-SQL is run via a stored procedure?

• User authentication using CodeIgniter

  - by marcin_koss

  I have a problem creating authentication part for my application. Below is the simplified version of my controllers. The idea is that the MY_controller checks if session with user data exists. If it doesn’t, then redirects to the index page where you have to log in. MY_controller.php class MY_Controller extends Controller { function __construct() { parent::__construct(); $this->load->helper('url'); $this->load->library('session'); if($this->session->userdata('user') == FALSE) { redirect('index'); } else { redirect('search'); } } } order.php - main controller class Orders extends MY_Controller { function __construct() { parent::__construct(); $this->load->helper('url'); $this->load->library('session'); } function index() { // Here would be the code that validates information input by user. // If validation is successful, it creates user session. $this->load->view('header.html', $data); // load header $this->load->view('index_view', $data); // load body $this->load->view('footer.html', $data); // load footer } function search() { //different page } what is happening is that the browser is telling me that “The page isn’t redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete.” It seems like the redirect() is being looped. I looked at a few other examples of user auth and they were build using similar technique.

• ODBC Linked server in sql 2005 doesn’t work from remote box

  - by mhj96813

  I have a dev workstation with sql 2005 installed and in it I created a linked server to a odbc connection to a clarion database. I can run select statements against it inside sql Mgt studio. When I take a second workstation and connect to the sql on the first box using sql mgt studio, then try the exact same query I get OLE DB provider "MSDASQL" for linked server "liveclarion" returned message "[SoftVelocity Inc.][TopSpeed ODBC Driver][ISAM]ISAM Table Not Found". Any thoughts? It appears to have the same functionality on a second sql server. No remote sql mgt studio connect success in queries against my linked ODBC clarion DB. All done with windows authentication and the same AD user.

• Executing a .NET Managed Assembly from SQL Server 2008 - Pro's, Con's & Recommendations

  - by RPM1984

  Hi guys, looking for opinions/recommendations/links for the following scenario im currently facing. The Platform: .NET 4.0 Web Application SQL Server 2008 The Task: Overhaul a component of the system that performs (fairly) complex mathematical operations based on a specific user activity, and updates numerous tables in the database. A common user activity might be "Bob" decides to post a forum topic. This results in (the end-solution) needing to look at various factors (about the post he did), then after doing some math based on lookup values/ratios as well as other data in the database, inserting some other data as a result of these operations. The Options: Ok - so here's what im thinking. Although it would be much easier to do this in C# (LINQ-SQL) it doesnt make much sense as the majority of the computations are based on values in the db, and it will get difficult to control/optimize/debug the LINQ over time. Hence, im leaning towards created a managed assembly (C# Class Library) that contains the lookup values (constants) as well as leveraging the math classes in the existing .NET BCL. Basically i'd expose a few methods that can be called by the T-SQL Stored Procedures. This to me has the following advantages: Simplicity of math. Do complex math in .NET vs complex math in T-SQL. No brainer. =) Abstraction of computatations, configurable "lookup" values and business logic from raw T-SQL. T-SQL only needs to care about the data, simplifying the stored procedures and making it easier to maintain. When it needs to do math it delegates off to the managed assembly. So, having said that - ive never done this before (call .NET assmembly from T-SQL), and after some googling the best site i could come up with is here, which is useful but outdated. So - what am i asking? Well, firstly - i need some better references on how to actually do this. "This" being how to call a C# .NET 4 Assembly from within T-SQL Stored Procedures in SQL Server 2008. Secondly, who out there has done this, what problems (if any) did you face? Realize this may be difficult to provide a "correct answer", so ill try to give it to whoever gives me the answer with a combination of good links and a list of pro's/con's/problems with this implementation. Cheers!

• SQL Server 2008 - cannot register default instance MSSQLSERVER

  - by Paul Moss

  Hello, I have installed SQL Server 2008 Developer on Windows 7 64 bit. In Management Studio I cannot register the default instance MSSQLSERVER, it cannot find it although the service is running. I get the message: Cannot connect to PHOENIX\MSSQLSERVER. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) (Microsoft SQL Server, Error: 87) However Management Studio does show the SQL Server 2005 Express instance (that was installed with VS 2008 Pro) which appeared as already registered. I an using Windows Authentication as I installed it in mixed mode. Any ideas would be appreciated, many thanks paul

• Drupal 7: cancel user registration if a wrong field value has been submitted.

  - by Alexander Farber

  Hello, I have a Drupal 7 with 1 field added to registration form - a List with possible values Robot / Male / Female: # select * from field_data_field_gender; entity_type | bundle | deleted | entity_id | revision_id | language | delta | field_gender_value -------------+--------+---------+-----------+-------------+----------+-------+-------------------- user | user | 0 | 6 | 6 | und | 0 | Male user | user | 0 | 5 | 5 | und | 0 | Male user | user | 0 | 7 | 7 | und | 0 | Female user | user | 0 | 1 | 1 | und | 0 | Male The first value Robot is a default value - to prevent SPAM robots from registering at my site. Is there a way to cancel user registration, when a new user submits the registration web form with the default Robot value? (i.e. only Male and Female values are allowed). I've looked at the core Trigger module, but don't see anything suitable there. I've looked at the hook_user_presave and hook_user_insert API docs, but don't see a way there to cancel an ongoing user registration. (I was expecting to do that by returning a special value from those methods...) Thank you! Alex

• How to create select SQL statement that would produce "merged" dataset from two tables(Oracle DBMS)?

  - by Roman Kagan

  Here's my original question: merging two data sets Unfortunately I omitted some intircacies, that I'd like to elaborate here. So I have two tables events_source_1 and events_source_2 tables. I have to produce the data set from those tables into resultant dataset (that I'd be able to insert into third table, but that's irrelevant). events_source_1 contain historic event data and I have to do get the most recent event (for such I'm doing the following: select event_type,b,c,max(event_date),null next_event_date from events_source_1 group by event_type,b,c,event_date,null events_source_2 contain the future event data and I have to do the following: select event_type,b,c,null event_date, next_event_date from events_source_2 where b>sysdate; How to put outer join statement to fill the void (i.e. when same event_type,b,c found from event_source_2 then next_event_date will be filled with the first date found GREATLY APPRECIATE FOR YOUR HELP IN ADVANCE.

• Assign Multiple Custom User Roles to a Custom Post Type

  - by OUHSD Webmaster

  Okay here's the situation.... I'm working on a my business website. There will be a work/portfolio area. "Work" is a custom post type. "Designer" is a custom user role. "Client" is a custom user role. In creating a new "Work" post I would like to be able to select both a "designer" and "Client" to assign to the piece of work, as I would assign an author to a regular ol' post. I tried the method from this answer but it did not work for me. ) I placed it in my functions.php file. ` add_filter('wp_dropdown_users', 'test'); function test($output) { global $post; //Doing it only for the custom post type if($post->post_type == 'work') { $users = get_users(array('role'=>'designer')); //We're forming a new select with our values, you can add an option //with value 1, and text as 'admin' if you want the admin to be listed as well, //optionally you can use a simple string replace trick to insert your options, //if you don't want to override the defaults $output .= "<select id='post_author_override' name='post_author_override' class=''>"; foreach($users as $user) { $output .= "<option value='".$user->id."'>".$user->user_login."</option>"; } $output .= "</select>"; } return $output; } ` Any help would be extremely appreciated!

• SQL: How can i update a value on a column only if that value is null?

  - by user321185

  Hey, I have an SQL question which may be basic to some but is confusing me. Here is an example of column names for a table 'Person': PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood Let's say that I input the row: 121312, Rayna, Pieterson, BMW123d, Brown, NULL, NULL Now I want to update the values for this person, but only if the new value is not null, Update: 121312, Rayna, Pieterson, NULL, Blonde, Fanta, NULL The new row needs to be: 121312, Rayna, Pieterson, BMW123d, Blonde, Fanta, NULL So I was thinking something along the lines of: Update Person(PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood) set Car = @Car (where @Car is not null), HairColour = @HairColour (where @HairColour...)... etc. My only concern is that I can't group all the conditions at the end of the query because it will require all the values to have the same condition. Can't i do something like Update HairColour if @HairColour is not Null

• SQL: without a cursor, how to select records making a unique integer id (identity like) for dups?

  - by Dr. Zim

  If you have the select statement below where the PK is the primary key: select distinct dbo.DateAsInt( dateEntered) * 100 as PK, recordDescription as Data from MyTable and the output is something like this (the first numbers are spaced for clarity): PK Data 2010 01 01 00 New Years Day 2010 01 01 00 Make Resolutions 2010 01 01 00 Return Gifts 2010 02 14 00 Valentines day 2010 02 14 00 Buy flowers and you want to output something like this: PK Data 2010 01 01 01 New Years Day 2010 01 01 02 Make Resolutions 2010 01 01 03 Return Gifts 2010 02 14 01 Valentines day 2010 02 14 02 Buy flowers Is it possible to make the "00" in the PK have an "identity" number effect within a single select? Otherwise, how could you increment the number by 1 for each found activity for that date? I am already thinking as I type to try something like Sum(case when ?? then 1 end) with a group by.

• A simple group-by (no count) in Django

  - by Daniel Quinn

  If this were raw-SQL, it'd be a no-brainer, but in Django, this is proving to be quite difficult to find. What I want is this really: SELECT user_id FROM django_comments WHERE content_type_id = ? AND object_pk = ? GROUP BY user_id It's those last two lines that're the problem. I'd like to do this the "Django-way" but the only thing I've found is mention of aggregates and annotations, which I don't think solve this issue... do they? If someone could explain this to me, I'd really appreciate it.

• Link Button on asp.net user control not firing

  - by andyriome

  Hi I have a user control, which is added to another user control. The nested user control is built up of a gridview, an image button and a link button. The nested user control is added to the outer control as a collection object based upon the results bound to the gridview. The problem that I have is that my link button doesn't work. I click on it and the event doesn't fire. Even adding a break point was not reached. As the nested user control is added a number of times, I have set image button to have unique ids and also the link button. Whilst image button works correctly with its java script. The link button needs to fire an event in the code behind, but despite all my efforts, I can't make it work. I am adding the link button to the control dynamically. Below is the relevant code that I am using: public partial class ucCustomerDetails : System.Web.UI.UserControl { protected override void CreateChildControls( ) { base.CreateChildControls( ); string strUniqueID = lnkShowAllCust.UniqueID; strUniqueID = strUniqueID.Replace('$','_'); this.lnkShowAllCust.ID = strUniqueID; this.lnkShowAllCust.Click += new EventHandler(this.lnkShowAllCust_Click); this.Controls.Add(lnkShowAllCust); } protected override void OnInit (EventArgs e) { CreateChildControls( ); base.OnInit(e); } protected override void OnLoad(EventArgs e) { base.EnsureChildControls( ); } protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) { CreateChildControls( ); } } protected void lnkShowAllCust_Click(object sender, EventArgs e) { this.OnCustShowAllClicked(new EventArgs ( )); } protected virtual void OnCustShowAllClicked(EventArgs args) { if (this.ViewAllClicked != null) { this.ViewAllClicked(this, args); } } public event EventHandler ViewAllClicked; } I have been stuggling with this problem for the last 3 days and have had no success with it, and I really do need some help. Can anyone please help me?
