  • Today’s Performance Tip: Views are for Convenience, Not Performance!

    - by Jonathan Kehayias
    I tweeted this last week on twitter and got a lot of retweets so I thought that I’d blog the story behind the tweet. Most vendor databases have views in them, and when people want to retrieve data from a database, it seems like the most common first stop they make are the vendor supplied Views.  This post is in no way a bash against the usage or creation of Views in a SQL Server Database, I have created them before to simplify code and compartmentalize commonly required queries so that there...(read more)

  • Is it wise to store a big lump of json on a database row

Is there any other way of doing this? I'm thinking of the following, but the current setup is really the most convenient one since I also have to use the data on the client side: store the product details in a file. So something like ASIN123.json store the product details in one big file. (I'm guessing it will be a drag to extract data from this file) store each of the fields in the details in its own table field Thanks in advance!

  • SQL SERVER – Storing 64-bit Unsigned Integer Value in Database

    - by Pinal Dave
    Here is a very interesting question I received in an email just another day. Some questions just are so good that it makes me wonder how come I have not faced it first hand. Anyway here is the question - “Pinal, I am migrating my database from MySQL to SQL Server and I have faced unique situation. I have been using Unsigned 64-bit integer in MySQL but when I try to migrate that column to SQL Server, I am facing an issue as there is no datatype which I find appropriate for my column. It is now too late to change the datatype and I need immediate solution. One chain of thought was to change the data type of the column from Unsigned 64-bit (BIGINT) to VARCHAR(n) but that will just change the data type for me such that I will face quite a lot of performance related issues in future. In SQL Server we also have the BIGINT data type but that is Signed 64-bit datatype. BIGINT datatype in SQL Server have range of -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807). However, my digit is much larger than this number. Is there anyway, I can store my big 64-bit Unsigned Integer without loosing much of the performance of by converting it to VARCHAR.” Very interesting question, for the sake of the argument, we can ask user that there should be no need of such a big number or if you are taking about identity column I really doubt that if your table will grow beyond this table. Here the real question which I found interesting was how to store 64-bit unsigned integer value in SQL Server without converting it to String data type. After thinking a bit, I found a fairly simple answer. I can use NUMERIC data type. I can use NUMERIC(20) datatype for 64-bit unsigned integer value, NUMERIC(10) datatype for 32-bit unsigned integer value and NUMERIC(5) datatype for 16-bit unsigned integer value. Numeric datatype supports 38 maximum of 38 precision. Now here is another thing to keep in mind. Using NUMERIC datatype will indeed accept the 64-bit unsigned integer but in future if you try to enter negative value, it will also allow the same. Hence, you will need to put any additional constraint over column to only accept positive integer there. Here is another big concern, SQL Server will store the number as numeric and will treat that as a positive integer for all the practical purpose. You will have to write in your application logic to interpret that as a 64-bit Unsigned Integer. On another side if you are using unsigned integers in your application, there are good chance that you already have logic taking care of the same.

I've tried purging wine/* but that had unresolved dependencies as well. It's a giant mess.

  • Designing a completely new database/gui solution for my compnay

    - by user1277304
    I'm no expert when it come to everything Visual Studio 2010 and utilizing SQL server 2008. I'm sure some of my personal projects I've built for personal use would get laughed off the face of the planet, but SQLCe has been the solution I was looking for those home type of projects. And they work, flawlessly. Now I feel it's time to step up to the big league. I want to develop a complete, unified and module based solution for my company that I'm working for. We're still using stuff from the 80s for goodness sake! I use Excel and query the ancient database on my own because I can't stand the GUI. Nothing against people of age, but the IDE our programmers are using is from the stone age, and they use APL of all things with it. I've yet to see a radio button control anywhere in the GUI where it would make sense. Anyway, I want to do this right from the ground up. I'm by no means a newbie when it comes to programming in .NET 2010, however, I want the entire solution to be professionally done. I want version control, test projects, project flow, SQL 2008 integration and all the bells and whistles that come with that. I know for a fact that if we had something like that running, not only would development costs and time be slashed four fold, but the possibilities for expansion and performance would sky rocket. (Between the GUI an our DB engine, it can only use ONE CORE! ONE! It's 2012 for goodness sake!) Our business is growing and our current ancient solution just can't keep up, and I'd hate to see our business go down in flames because our programmer is stuck in the 80's and refuses to use anything current. So I ask you guys, the experts and know-it-alls, where do I start? Are there any gems of good books out there in the haystack of all "This for dummies" type of deals? I already have several people backing me in this endeavor, and while it may seem brash to just usurp the current programmers, I'm doing this for the company as a whole.

  • Managing Data Growth in SQL Server

    'Help, my database ate my disk drives!'. Many DBAs spend most of their time dealing with variations of the problem of database processes consuming too much disk space. This happens because of errors such as incorrect configurations for recovery models, data growth for large objects and queries that overtax TempDB resources. Rodney describes, with some feeling, the errors that can lead to this sort of crisis for the working DBA, and their solution.

  • Prolog - How do you distinguish between just a string, and a variable? [closed]

    - by Mr Prolog
    When you are querying a Prolog database, often you will use terms that start with an uppercase letter as your variables. However, let's say that one of the constraints on your query is that a person's location must be "Dallas", and you want to query all the information in the database who meet those specifications. How would do you correctly make sure that Dallas is not interpreted as a variable to store a value in, and is interpreted as a string instead, for usage as a constraint on the query?

  • XMLHttpRequest not working, trying to test database connection [closed]

    - by Frederick Marcoux

  • Taking a Projects Development to the Next Level

    - by user1745022
    I have been looking for some advice for a while on how to handle a project I am working on, but to no avail. I am pretty much on my fourth iteration of improving an "application" I am working on; the first two times were in Excel, the third Time in Access, and now in Visual Studio. The field is manufacturing. The basic idea is I am taking read-only data from a massive Sybase server, filtering it and creating much smaller tables in Access daily (using delete and append Queries) and then doing a bunch of stuff. More specifically, I use a series of queries to either combine data from multiple tables or group data in specific ways (aggregate functions), and then I place this data into a table (so I can sort and manipulate data using DAO.recordset and run multiple custom algorithms). This process is then repeated multiple times throughout the database until a set of relevant tables are created. Many times I will create a field in a query with a value such as 1.1 so that when I append it to a table I can store information in the field from the algorithms. So as the process continues the number of fields for the tables change. The overall application consists of 4 "back-end" databases linked together on a shared drive, with various output (either front-end access applications or Excel). So my question is is this how many data driven applications that solve problems essentially work? Each backend database is updated with fresh data daily and updating each takes around 10 seconds (for three) and 2 minutes(for 1). Project Objectives. I want/am moving to SQL Server soon. Front End will be a Web Application (I know basic web-development and like the administration flexibility) and visual-studio will be IDE with c#/.NET. Should these algorithms be run "inside the database," or using a series of C# functions on each server request. I know you're not supposed to store data in a database unless it is an actual data point, and in Access I have many columns that just hold calculations from algorithms in vba. The truth is, I have seen multiple professional Access applications, and have never seen one that has the complexity or does even close to what mine does (for better or worse). But I know some professional software applications are 1000 times better then mine. So Please Please Please give me a suggestion of some sort. I have been completely on my own and need some guidance on how to approach this project the right way.

  • Auditing DDL Changes in SQL Server databases

    Even where Source Control isn't being used by developers, it is still possible to automate the process of tracking the changes being made to a database and put those into Source Control, in order to track what changed and when. You can even get an email alert when it happens. With suitable scripting, you can even do it if you don't have direct access to the live database. Grant shows how easy this is with SQL Compare.

  • Help with DB Structure, vOD site

    - by Chud37
    I have a video on demand style site that hosts series of videos under different modules. However with the way I have designed the database it is proving to be very slow. I have asked this question before and someone suggested indexing, but i cannot seem to get my head around it. But I would like someone to help with the structure of the database here to see if it can be improved. The core table is Videos: ID bigint(20) (primary key, auto-increment) pID text airdate text title text subject mediumtext url mediumtext mID int(11) vID int(11) sID int(11) pID is a unique 5 digit string to each video that is a shorthand identifier. Airdate is the TS, (stored in text format, right there maybe I should change that to TIMESTAMP AUTO UPDATE), title is self explanatory, subject is self explanatory, url is the hard link on the site to the video, mID is joined to another table for the module title, vID is joined to another table for the language of the video, (english, russian, etc) and sID is the summary for the module, a paragraph stored in an external database. The slowest part of the website is the logging part of it. I store the data in another table called 'Hits': id mediumint(10) (primary key, auto-increment) progID text ts int(10) Again, here (this was all made a while ago) but my Timestamp (ts) is an INT instead of ON UPDATE CURRENT TIMESTAMP, which I guess it should be. However This table is now 47,492 rows long and the script that I wrote to process it is very very slow, so slow in fact that it times out. A row is added to this table each time a user clicks 'Play' on the website and then so the progID is the same as the pID, and it logs the php time() timestamp in ts. Basically I load the entire database of 'Hits' into an array and count the hits in each day using the TS column. I am guessing (i'm quite slow at all this, but I had no idea this would happen when I built the thing) that this is possibly the worst way to go about this. So my questions are as follows: Is there a better way of structuring the 'Videos' table, is so, what do you suggest? Is there a better way of structuring 'hits', if so, please help/tell me! Or is it the fact that my tables are fine and the PHP coding is crappy?

  • WDS "No response" only when notify and wait for approval

    - by Cylindric
    I have a WDS server setup for use with MDT2010, and everything was working fine until this morning. Now, whenever I try to boot from LAN, I get an error: Downloaded WDSNBP... Architecture: x64 WDSNBP started using DHCP Referral. Contacting Server: 10.50.10.12 (Gateway: 0.0.0.0) No response from Windows Deployment Services server. Launching pxeboot.com My PXE Response Policy setting on the WDS is set to this: [ ] Do not respond to any client computer [ ] Respond only to known client computers [o] Respond to all (known and unknown) client computers [X] For unknown clients, notify administrator and respond after approval The odd thing is that if I clear the approval option (so any computer gets a response) it works fine. I have delegated permissions on the AD OU to the computer object WDS is running on, but that doesn't seem to have helped. As it works without approval, I can only assume my DHCP options are fine and this is some sort of AD permission problem. (Server is Windows Server 2008 SP2)

  • How to make sure my GPO are applied in the correct order

    - by Florent
    I'm deploying VMware player through a GPO, and I'd like to apply specific ACLs to the install folder, and to the D:\VMWARE folder I'm creating during the player install. I also have to add the vmware user account the "can log on locally" right. To do so, I've created a GPO whose scope is the same as my Vmware player install GPO. This GPO works well, BUT when applied at the same time as my deployment GPO, it seems to be applied before the deploy GPO, and then : - Cannot find the vmware user account - Cannot find the c:\program files\vmware folder - Cannot find the D:\vmware folder because none of them have already been created by the vmware player install. And the only way for me to apply my security GPO is to execute gpudate /force command manually, which i don't want to use (it's supposed to be an automatic install) I've checked the gpo processing order, my security GPO should be applied AFTER my install GPO (security GPO is number 1, deploy GPO is number to), but it don't seem to be the case. Does anyone got an idea to solve this ?

  • Windows 7 Pro sysprep not working

    - by Callum D
    Hello, I'm trying to sysprep a Windows 7 Professional machine, prior to grabbing an image for mass deployment on identical hardware, and am having a hard time getting sysprep to work (at all). I've created an XML answer file with WSIM, and have a basic setupcomplete.cmd file, but none of the configurations in the answer file seem to be applied. I've read technet articles and googled, and I still have no idea why this is happening. Is someone able to have a look at the answer file I've attached and let me know where I'm going wrong? thanks, Callum AutoUnattend.XML <?xml version="1.0" encoding="utf-8"?> <unattend xmlns="urn:schemas-microsoft-com:unattend"> <settings pass="specialize"> <component name="Microsoft-Windows-Shell-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <AutoLogon> <Password> <Value>**********************************</Value> <PlainText>false</PlainText> </Password> <Username>administrator</Username> <LogonCount>1</LogonCount> <Enabled>true</Enabled> </AutoLogon> <WindowsFeatures> <ShowMediaCenter>false</ShowMediaCenter> <ShowWindowsMediaPlayer>false</ShowWindowsMediaPlayer> </WindowsFeatures> <CopyProfile>true</CopyProfile> <DoNotCleanTaskBar>true</DoNotCleanTaskBar> <RegisteredOrganization>SomeCompany (UK) Ltd.</RegisteredOrganization> <RegisteredOwner>SomeCompany User</RegisteredOwner> <ShowWindowsLive>false</ShowWindowsLive> <TimeZone>GMT Standard Time</TimeZone> </component> <component name="Security-Malware-Windows-Defender" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <DisableAntiSpyware>true</DisableAntiSpyware> </component> </settings> <settings pass="oobeSystem"> <component name="Microsoft-Windows-International-Core" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <SystemLocale>en-UK</SystemLocale> <UserLocale>en-UK</UserLocale> <UILanguage>en-US</UILanguage> <InputLocale>0809:00000809</InputLocale> </component> <component name="Microsoft-Windows-Shell-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <OOBE> <HideEULAPage>true</HideEULAPage> <HideWirelessSetupInOOBE>true</HideWirelessSetupInOOBE> <NetworkLocation>Work</NetworkLocation> <ProtectYourPC>1</ProtectYourPC> </OOBE> <UserAccounts> <AdministratorPassword> <Value>*************************************************=</Value> <PlainText>false</PlainText> </AdministratorPassword> </UserAccounts> </component> <component name="Microsoft-Windows-Deployment" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <Reseal> <Mode>OOBE</Mode> </Reseal> </component> </settings> <settings pass="generalize"> <component name="Microsoft-Windows-Security-SPP" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <SkipRearm>0</SkipRearm> </component> </settings> <settings pass="windowsPE"> <component name="Microsoft-Windows-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <UseConfigurationSet>true</UseConfigurationSet> </component> </settings> <cpi:offlineImage cpi:source="wim:c:/wim/install.wim#Windows 7 PROFESSIONAL" xmlns:cpi="urn:schemas-microsoft-com:cpi" /> </unattend>

  • How to manage credentials on multiserver environment

    - by rush
    I have a some software that uses its own encrypted file for password storage ( such as ftp, web and other passwords to login to external systems, there is no way to use certificates ). On each server I've several instances of this software, each instance has its own password file. At the moment number of servers is permanently growing and it's getting harder and harder to manage all passwords on all instances up to date. Unfortunately, some servers are in cegregated network and there is no access from them to some centralized storage, but it works vice versa. My first idea was to create a git repository, encrypt each password with gpg and store it there and deliver it within deployment system, but security team was not satisfied with this idea and as it is insecure to store passwords in repository even in encrypted view ( from their words ). Nothing similar comes to my mind. Is there any way to implement safe and secure password storage with minimal effort to manage all passwords up-to-date? ps. if that matters I've red hat everywhere.

  • Going from imagex/AIK to WDT

    - by lross1309
    I was looking learning Windows Deployment Toolkit. I have been using AIK to create answer files and sysprep to clean the referece computer and imagex to capture and apply images. I have some .wim files I need to keep (they also have an answer file in them). I was wondering, if I start using WDT, can I import these images and have WDT deploy them or do I have to start over with capturing the images using WDT? If I can import, how do you deploy them in the same manner that imagex would use the images internal answer file using WDT? Leon

  • deploying a Python application from a PHP developer

    - by user1218776
    I'm a little confused on the deployment process for Python. Let's say you create a brand new project with virtualenv source bin/activate pip install a few libraries write a simple hello world app pip freeze the dependencies When I deploy this code into a machine, do I need first make sure the machine is sourced before installing dependencies? I don't mean to sound like a total noob but in the PHP world, I don't have to worry about this because it's already part of the project. All the dependencies are registered with the autoloader in place. The steps would be: rsync the files (or any other method) source bin/activate pip install the dependencies from the pip freeze output file It feels awkward, or just wrong and very error prone. What are the correct steps to make? I've searched around but it seems many tutorials/articles make an assumption that anyone reading the article has past python experience (imo).

  • What is the best way to clone Win7 machines?

    - by John Hoge
    I'm looking to buy 5 new Win7 boxes and would like to ease deployment by cloning the OS. What I would like to do is install a fresh OS (Dell doesn't seem to sell machines without preinstalled crapware anymore) and then install a few apps on the first one. Once it is just right, I want to clone the OS and install the image on the other four machines and just change the machine name. Is this possible to do without any extra third party software? What I am thinking of doing is backing up the disk image of the first machine to a network share, and then booting the others to the windows install DVD and restoring the same image on each machine. Has anyone had any luck with this technique?

  • Remote deploying wars to a liferay installation

    - by iftrue
    With vanilla tomcat, you can POST to URLs beneath SOMURL/manager/ with a proper manager user role defined. The liferay deployment of tomcat, however, is missing the manager and host-manager applications, and when I copy the directories from a vanilla Tomcat installation, I get the exception below: Exception: javax.servlet.ServletException: Error allocating a servlet instance org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:558) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:636) root cause java.lang.SecurityException: Servlet of class org.apache.catalina.manager.HTMLManagerServlet is privileged and cannot be loaded by this web application org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:558) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:636) What's the proper way to remote deploy wars to a liferay instance? (Not portlets, in my case.)
