  • Is it possible to have a cell in table1 "point to" a cell in table2?

    - by Lewray
    I have a hierarchical structure in a database driven software application. Each row in parentTable 'owns' a number of rows in childTable. If the childTable does not have a value set in columnA then it should return the value specified in the appropriate row of parentTable columnB. Is it possible to implement a pointer or cell reference somehow so that I do not have to copy values from parent to child. (A change in parent could result in a large number of changes in child). If this is not possible, could anyone suggest a different approach?

  • Connect to my virtualbox mysql server

    - by WebweaverD
    I wonder if someone here could help me, this is my set up: I am on a windows 7 machine running a ubuntu virtualbox as my local web server and database server (mysql). I have just got hold of a copy of Komodo which i am running on my windows machine which I would like to hook up to my database. The fields it needs are hostname, port, socket, username and password. I know the username/password but am unsure how to find out what to put for the other fields. The ubuntu vb has an ip of 192.168.0.10, which is in my hosts file as http://swishprint.dev I hope I have asked this in the right place, any help much appreciated.

  • How can records be deleted without activating the delete trigger?

    - by Servaas Phlips
    Hello there, Since about a month we are experiencing records that are disappearing from our database without any reason. (part of) Our database structure is at http://i.imgur.com/i15nG.png Now users and credentials can never be deleted. We noticed however that thanks to our backups that unfortanetely users disappeared from the database. The users and credentials that disappear appear to be completely random. In order to find out which application deletes this records we created triggers with the following checks: CREATE TRIGGER Credential_SoftDelete ON [Credential] INSTEAD OF DELETE AS DECLARE @message nvarchar(255) DECLARE @hostName nvarchar(30) DECLARE @loginName nvarchar(30) DECLARE @deletedId nvarchar(30) SELECT @deletedId=credentialid FROM deleted; SELECT @hostName=host_name,@loginName=login_name FROM sys.dm_exec_sessions WHERE session_id=@@SPID; SELECT @message = '[FAULT] Credential : ' + USER_NAME() + ' deleted ' +@deletedId + ' on ' + @@SERVERNAME + ' from [' + @hostname + ' by ' + @loginName; EXEC xp_logevent 50001,@message,ERROR GO Now after we added this trigger we hoped to find out which application deletes these credentials by searching in the log files. Unfortanetely the credentials are still deleted and the trigger Credential_SoftDelete is never logged. I did try run a delete on the database where the trigger is installed and where the users have disappeared. I ran the following query on the database: DELETE FROM [User] WHERE userid=296 and the trigger prevented deletion of this user and also logged this in the log events. This was actually on exact the same database where the users disappeared. (so no test copy or something like that) Please note that we also use replication, the type of replication we use is merge replication. How is this possible? Can the fact that we use replication on this database be the cause of this problem?

  • Windows, Apache and MSSQL Authentication

    - by user1114330
    I have a create database script written in perl. I remember it working just fine another machine. A couple years later using a Vista machine I am trying to use it again and it keeps failing. The main difference is that now I am using Apache instead of IIS. In the script the IUSR account is granted permissions as it needs to write to the database as a part of another program. IIS has been uninstalled on this machine but the IUSR account still exists. The NT AUTHORITY\IUSR is also seen in the logins drop down in MSSQL(2012). The machine is running Vista Home Edition. However when running the script I get errors that say that NT AUTHORITY\IUSR cannot be found. I tried also with COMPUTERNAME\IUSR just for the heck of it and of course it was not found. I also tried with IUSR alone and for some reason the user isn't being "found"? Any ideas?

  • What questions do I need to ask for a database sync?

    - by user65745
    I am currently helping to implement an RFID inventory management system for my company. The software that we are locked into has been at best buggy and unreliable. The software provider is now rolling out a major release. My problem is that the new software release keeps a local database on each machine that then syncs to a master database online. According to the software company we cannot do a scaled rollout because of data corruption issues between the software releases. What questions can I be asking and what sort of testing can I do on my end to make sure this software works? Any suggestions would be very helpful.

  • MySQL reclaim index space after large delete?

    - by cdunn
    After performing a large delete in MySQL, I understand you need to run a NULL ALTER to reclaim disk space, is this also true for reclaiming index space? We have tables using 10G of index space and have deleted/archived large chunks of this data and unsure if we need to rebuild the table in order to decrease the size of the index. Can anyone offer any advice? We are trying to avoid rebuilding the table since it would take quite awhile and lock the table. Thanks!

  • Matching a smaller piece of text in a local variable to a larger piece of text that I have pulled in a query

    - by Hoser
    I think this is a simple question, but google searching for 30 minutes was mostly wasted time as all I can find is matching a variable to a 'randompieceoftext'. Anyways, suppose I have a local variable called @ServerName. This server name will be something like CCPWIQAUL. I need to match this server name to various path names, which is of the form: serverName.something.somethingelse.com These path names are pulled from a database, and will be in the column vManagedEntity.Path How do I do something like this? Is @ServerName is IN vManagedEntity.Path?

  • Too many connections to Sql Server 2008

    - by Luis Forero
    I have an application in C# Framework 4.0. Like many app this one connects to a data base to get information. In my case this database is SqlServer 2008 Express. The database is in my machine In my data layer I’m using Enterprise Library 5.0 When I publish my app in my local machine (App Pool Classic) Windows Professional IIS 7.5 The application works fine. I’m using this query to check the number of connections my application is creating when I’m testing it. SELECT db_name(dbid) as DatabaseName, count(dbid) as NoOfConnections, loginame as LoginName FROM sys.sysprocesses WHERE dbid > 0 AND db_name(dbid) = 'MyDataBase' GROUP BY dbid, loginame When I start testing the number of connection start growing but at some point the max number of connection is 26. I think that’s ok because the app works When I publish the app to TestMachine1 • XP Mode Virtual Machine (Windows XP Professional) • IIS 5.1 It works fine, the behavior is the same, the number of connections to the database increment to 24 or 26, after that they stay at that point no matter what I do in the application. The problem: When I publish to TestMachine2 (App Pool Classic) • Windows Server 2008 R2 • IIS 7.5 I start to test the application the number of connection to the database start to grow but this time they grow very rapidly and don’t stop growing at 24 or 26, the number of connections grow till the get to be 100 and the application stop working at that point. I have check for any difference on the publications, especially in Windows Professional and Windows Server and they seem with the same parameters and configurations. Any clues why this could be happening? , any suggestions?

  • Spoof database connection to be local instead of remote

    - by spydon
    I am trying to connect one of our clients "as is" programs to a remote database instead of a local one, they say that they have coded it to be able to do it, but for some reason the program crashes when trying to connect to a remote database. I don't have the source code so I can't really dig much deeper than that and the company does not provide any upgrades or custom modifications. I can succesfully connect to the database through SqlDbx and HeidiSQL so I know that the server is set up correctly. This is why I need to find a way to spoof a remote connection on port 1433 to appear like a local database connection to the program. I thought about editing the hosts file, but it will most likely crash other programs if I bind localhost to another IP than 127.0.0.1. Any ideas?

  • Should I never put a transactional replication distributor on a subscriber server?

    - by Stuart Branham
    What factors into choosing a distribution server for transactional replication? In our topology, we've always had the distributor reside on the publishing server. We rarely generate snapshots and performance is good enough, so this is okay for us today. One of our instances is moving to a cluster, so we need to move the distributor off for resilience/symmetry. Right now our two choices are to use a server physically close to the publishers, or our single subscription server. Our publisher is in our main office, and our subscriber is in a colocation facility off-site which our ISP runs. We have a pretty good line to it. The reason we're even considering the latter is to save work and licensing costs.

  • How to use filegroups for DB split?

    - by Robin Jain
    In my project I have one DB used for everything. I want it to break into two databases. Static tables having look up values are to be stored in one DB and another DB would be having tables with dynamic data. My problem is that how would I use foreign key constraint in between those two DBs. Can someone help me out and suggest a way to proceed, better if I'm provided an example for the same. I thought of using synonyms for tables and then constraints on synonyms. but later I came to know that synonyms couldn't be used for constraints. I need to maintain relationships among the tables from both DB as the issue is with update, with a new release I just want to update look up tables and for the same I want to split my DB. I want to know how FileGroups could be used for this.

  • Do I need to install mssql before I can use mssql.so with php on unix?

    - by lock
    I didn't install any MSSQL instance on my localhost that runs windows. I just used the xampp package and uncommented the modules used for mssql. The mssql server resides on another Windows Server so I believe I only needed a simple connector module. I hoped that it would be the same for Unix. But whenever I open my site on the unix production server, (i use codeigniter btw) the logs tell me it stops script execution after Database Driver Class Initialized. I am not really familiar on installing apache and friends on unix and I wasn't responsible on how the server was set-up. But it turns out that there is no mssql.so found on the php modules directory so i tried to google for one. While the forums are telling me to just compile the script, I couldn't just do that simply as I have no write access to the server and plus it seems upon installation of php, phpize didn't get installed with it too. Hope someone can shed light to me regarding this. I think its just easier if I can get a mssql.so for PHP 4.4.4

  • BizTalk Server 2013 beta on Windows 8 (with Visual Studio 2012, SQL Server 2012 &amp; ESB Toolkit 2.2)

    - by Vishal
    Hello BizTalkers, Finally, Microsoft released the beta version of BizTalk Server 2010 R2 and now its called BizTalk Server 2013. I had tried the BTS 2010 R2 CTP version on Windows Azure VM and particularly I was excited about the RESTful services support and ESB fully integrated into BizTalk. Well didn’t get chance to test it much, Azure & VM running cost associated . Anyways, I was waiting for this announcement and I was so much glad that Microsoft finally released the on premise one.  Check what’s new in the BizTalk Server 2013.  Officially Microsoft says that BizTalk Server 2013 “beta” is not supported on Windows 8 but I was curious to try it out. Below is my installation and configuration experience. Virtual Machine configuration: VM Ware Workstation 9.0. Windows 8 Enterprise x64. SQL Server 2012. Visual Studio 2012 Ultimate. BizTalk Server 2013 beta. Windows 8 Machine name: WIN8 Local Administrator account name: Admin First I installed Windows 8 Enterprise on a VM Ware Workstation 9.0 and updated the OS. Even Windows 8 is the new release so luckily didn’t had much updates to perform. Next Installed Visual Studio 2012 Ultimate which was straightforward installation. Next Installed SQL Server 2012. Select New SQL Server stand-alone installation & followed the steps as shown in the screenshot below.   Once the installation is finished, fire up SQL Server Management Studio and try connecting. Initially when the management studio opened up, I thought why did Visual Studio 2010 open when I tried opening SQL Management studio but well, they made the interface alike VS 2010. Cool, I like it. Next is the real deal, download the BizTalk Server 2013 and unzip to particular folder. Double click the Setup.exe and follow the steps in the screenshots. Install Microsoft BizTalk Server 2013 beta. I selected all the normal artifacts and also all the artifacts under Additional Software's. So far so good. Next Launch BizTalk Server Configuration and I used Basic configuration as shown in screenshot below. Didn’t expect to see this but “wala”. Successful in the first shot. Still I wasn’t sure & something would have gone wrong so fired up the BizTalk Server Administration Console and that too came up just fine. Still was not able to believe so created a simple messaging application:  message in –> message out and that too worked just fine. Finally I was convinced that BizTalk Server 2013 did work on Windows 8. Next step was to install the ESB Toolkit 2.2 which is now integrated with BizTalk Server and does not come as a separate standalone installation file. Again run the BizTalk Setup.exe from the unzipped folder. Install Microsoft ESB Toolkit. Next, unlike ESB Configuration would  not open up by itself so go to “Windows 8 so called Start” (I could not resist to write this) and open the ESB Toolkit Configuration wizard. Below screenshot display the configurations I used. Also you can find them on MSDN here. Finally after the ESB Configuration, I open Admin Console and checked the 2 ESB application deployed. Cool. This concludes my experience about installation and configuration of BizTalk Server 2013 Beta & ESB Toolkit 2.2 on Windows 8. I will try and keep writing about BizTalk Server 2013 and its use with RESTful Services etc. Thanks, Vishal Mody

  • GROUP_CONCAT in CodeIgniter

    - by mickaelb91
    I'm just blocking to how create my group_concat with my sql request in CodeIgniter. All my queries are listed in a table, using Jtable library. All work fine, except when I try to insert GROUP_CONCAT. Here's my model page : function list_all() { $login_id = $this->session->userdata('User_id'); $this->db->select('p.project_id, p.Project, p.Description, p.Status, p.Thumbnail, t.Template'); $this->db->from('assigned_projects_ppeople a'); $this->db->where('people_id', $login_id); $this->db->join('projects p', 'p.project_id = a.project_id'); $this->db->join('project_templates t', 't.template_id = p.template_id'); $this->db->select('GROUP_CONCAT(u.Asset SEPARATOR ",") as assetslist', FALSE); $this->db->from('assigned_assets_pproject b'); $this->db->join('assets u', 'u.asset_id = b.asset_id'); $query = $this->db->get(); $rows = $query->result_array(); //Return result to jTable $jTableResult = array(); $jTableResult['Result'] = "OK"; $jTableResult['Records'] = $rows; return $jTableResult; } My controller page : function listRecord(){ $this->load->model('project_model'); $result = $this->project_model->list_all(); print json_encode($result); } And to finish my view page : <table id="listtable"></table> <script type="text/javascript"> $(document).ready(function () { $('#listtable').jtable({ title: 'Table test', actions: { listAction: '<?php echo base_url().'project/listRecord';?>', createAction: '/GettingStarted/CreatePerson', updateAction: '/GettingStarted/UpdatePerson', deleteAction: '/GettingStarted/DeletePerson' }, fields: { project_id: { key: true, list: false }, Project: { title: 'Project Name' }, Description: { title: 'Description' }, Status: { title: 'Status', width: '20px' }, Thumbnail: { title: 'Thumbnail', display: function (data) { return '<a href="<?php echo base_url('project');?>/' + data.record.project_id + '"><img class="thumbnail" width="50px" height="50px" src="' + data.record.Thumbnail + '" alt="' + data.record.Thumbnail + '" ></a>'; } }, Template: { title: 'Template' }, Asset: { title: 'Assets' }, RecordDate: { title: 'Record date', type: 'date', create: false, edit: false } } }); //Load person list from server $('#listtable').jtable('load'); }); </script> I read lot of posts talking about that, like replace ',' separator by ",", or use OUTER to the join, or group_by('p.project_id') before using get method, don't work. Here is a the output of the query in json : {"Result":"OK","Records":[{"project_id":"1","Project":"Adam & Eve : A Famous Story","Description":"The story about Adam & Eve reviewed in 3D Animation movie !","Status":"wip","Thumbnail":"http:\/\/localhost\/assets\/images\/thumb\/projectAdamAndEve.png","Template":"Animation Movie","assetslist":"Apple, Adam, Eve, Garden of Eden"}]} We can see the GROUP_CONCAT is here (after "assetslist"), but the column stills empty. If asked, I can post the database SQL file. Thank you.

  • Combine config-paramters with parameters passed from commanline

    - by Frederik
    I have created a SSIS-package that imports a file into a table (simple enough). I have some variables, a few set in a config-file such as server, database, importfolder. at runtime I want to pass the filename. This is done through a stored procedure using dtexec. When setting the paramters throught the configfile it works fine also when setting all parameters in the procedure and passing them with the \Set statement (se below). when I try to combine the config-version with settings parameters on the fly I get an error refering to the config-files path that was set at design time. Has anybody come across this and found a solution for it?
