  • Windows XP clients do not update server 2008 DNS forward lookup zone.

    - by whatsisname
    I have a Cisco 5505 working as a DHCP server, and a server 2008 DNS server running an AD domain. I am having problems with all XP computers not updating the forward lookup zone. The reverse lookup zone updates are working. Windows vista and 7 computers update just fine. Additionally the DNS server accepts both secure and non-secure updates. When people are connected through the Cisco's VPN, they cannot resolve to any machines that have reverse lookup zones, but they can resolve entries in the forward lookup zone. I have tried ipconfig /registerdns, but the forward lookup zone entries for the XP clients are not being populated. How can I get the XP Dynamic DNS client to make the updates, or what can I do to debug what's going on? Thanks

  • SQL SERVER – Implementing IF … THEN in SQL SERVER with CASE Statements

    - by Pinal Dave
    Here is the question I received the other day in email. “I have business logic in my .net code and we use lots of IF … ELSE logic in our code. I want to move the logic to Stored Procedure. How do I convert the logic of the IF…ELSE to T-SQL. Please help.” I have previously received this answer few times. As data grows the performance problems grows more as well. Here is the how you can convert the logic of IF…ELSE in to CASE statement of SQL Server. Here are few of the examples: Example 1: If you are logic is as following: IF -1 < 1 THEN ‘TRUE’ ELSE ‘FALSE’ You can just use CASE statement as follows: -- SQL Server 2008 and earlier version solution SELECT CASE WHEN -1 < 1 THEN 'TRUE' ELSE 'FALSE' END AS Result GO -- SQL Server 2012 solution SELECT IIF ( -1 < 1, 'TRUE', 'FALSE' ) AS Result; GO If you are interested further about how IIF of SQL Server 2012 works read the blog post which I have written earlier this year . Well, in our example the condition which we have used is pretty simple but in the real world the logic can very complex. Let us see two different methods of how we an do CASE statement when we have logic based on the column of the table. Example 2: If you are logic is as following: IF BusinessEntityID < 10 THEN FirstName ELSE IF BusinessEntityID > 10 THEN PersonType FROM Person.Person p You can convert the same in the T-SQL as follows: SELECT CASE WHEN BusinessEntityID < 10 THEN FirstName WHEN BusinessEntityID > 10 THEN PersonType END AS Col, BusinessEntityID, Title, PersonType FROM Person.Person p However, if your logic is based on multiple column and conditions are complicated, you can follow the example 3. Example 3: If you are logic is as following: IF BusinessEntityID < 10 THEN FirstName ELSE IF BusinessEntityID > 10 AND Title IS NOT NULL THEN PersonType ELSE IF Title = 'Mr.' THEN 'Mister' ELSE 'No Idea' FROM Person.Person p You can convert the same in the T-SQL as follows: SELECT CASE WHEN BusinessEntityID < 10 THEN FirstName WHEN BusinessEntityID > 10 AND Title IS NOT NULL THEN PersonType WHEN Title = 'Mr.' THEN 'Mister' ELSE 'No Idea' END AS Col, BusinessEntityID, Title, PersonType FROM Person.Person p I hope this solution is good enough to convert the IF…ELSE logic to CASE Statement in SQL Server. Let me know if you need further information about the same.

  • SQL SERVER – Weekly Series – Memory Lane – #035

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Row Overflow Data Explanation  In SQL Server 2005 one table row can contain more than one varchar(8000) fields. One more thing, the exclusions has exclusions also the limit of each individual column max width of 8000 bytes does not apply to varchar(max), nvarchar(max), varbinary(max), text, image or xml data type columns. Comparison Index Fragmentation, Index De-Fragmentation, Index Rebuild – SQL SERVER 2000 and SQL SERVER 2005 An old but like a gold article. Talks about lots of concepts related to Index and the difference from earlier version to the newer version. I strongly suggest that everyone should read this article just to understand how SQL Server has moved forward with the technology. Improvements in TempDB SQL Server 2005 had come up with quite a lots of improvements and this blog post describes them and explains the same. If you ask me what is my the most favorite article from early career. I must point out to this article as when I wrote this one I personally have learned a lot of new things. Recompile All The Stored Procedure on Specific TableI prefer to recompile all the stored procedure on the table, which has faced mass insert or update. sp_recompiles marks stored procedures to recompile when they execute next time. This blog post explains the same with the help of a script.  2008 SQLAuthority Download – SQL Server Cheatsheet You can download and print this cheat sheet and use it for your personal reference. If you have any suggestions, please let me know and I will see if I can update this SQL Server cheat sheet. Difference Between DBMS and RDBMS What is the difference between DBMS and RDBMS? DBMS – Data Base Management System RDBMS – Relational Data Base Management System or Relational DBMS High Availability – Hot Add Memory Hot Add CPU and Hot Add Memory are extremely interesting features of the SQL Server, however, personally I have not witness them heavily used. These features also have few restriction as well. I blogged about them in detail. 2009 Delete Duplicate Rows I have demonstrated in this blog post how one can identify and delete duplicate rows. Interesting Observation of Logon Trigger On All Servers – Solution The question I put forth in my previous article was – In single login why the trigger fires multiple times; it should be fired only once. I received numerous answers in thread as well as in my MVP private news group. Now, let us discuss the answer for the same. The answer is – It happens because multiple SQL Server services are running as well as intellisense is turned on. Blog post demonstrates how we can do the same with the help of SQL scripts. Management Studio New Features I have selected my favorite 5 features and blogged about it. IntelliSense for Query Editing Multi Server Query Query Editor Regions Object Explorer Enhancements Activity Monitors Maximum Number of Index per Table One of the questions I asked in my user group was – What is the maximum number of Index per table? I received lots of answers to this question but only two answers are correct. Let us now take a look at them in this blog post. 2010 Default Statistics on Column – Automatic Statistics on Column The truth is, Statistics can be in a table even though there is no Index in it. If you have the auto- create and/or auto-update Statistics feature turned on for SQL Server database, Statistics will be automatically created on the Column based on a few conditions. Please read my previously posted article, SQL SERVER – When are Statistics Updated – What triggers Statistics to Update, for the specific conditions when Statistics is updated. 2011 T-SQL Scripts to Find Maximum between Two Numbers In this blog post there are two different scripts listed which demonstrates way to find the maximum number between two numbers. I need your help, which one of the script do you think is the most accurate way to find maximum number? Find Details for Statistics of Whole Database – DMV – T-SQL Script I was recently asked is there a single script which can provide all the necessary details about statistics for any database. This question made me write following script. I was initially planning to use sp_helpstats command but I remembered that this is marked to be deprecated in future. 2012 Introduction to Function SIGN SIGN Function is very fundamental function. It will return the value 1, -1 or 0. If your value is negative it will return you negative -1 and if it is positive it will return you positive +1. Let us start with a simple small example. Template Browser – A Very Important and Useful Feature of SSMS Templates are like a quick cheat sheet or quick reference. Templates are available to create objects like databases, tables, views, indexes, stored procedures, triggers, statistics, and functions. Templates are also available for Analysis Services as well. The template scripts contain parameters to help you customize the code. You can Replace Template Parameters dialog box to insert values into the script. An invalid floating point operation occurred If you run any of the above functions they will give you an error related to invalid floating point. Honestly there is no workaround except passing the function appropriate values. SQRT of a negative number will give you result in real numbers which is not supported at this point of time as well LOG of a negative number is not possible (because logarithm is the inverse function of an exponential function and the exponential function is NEVER negative). Validating Spatial Object with IsValidDetailed Function SQL Server 2012 has introduced the new function IsValidDetailed(). This function has made my life very easy. In simple words, this function will check if the spatial object passed is valid or not. If it is valid it will give information that it is valid. If the spatial object is not valid it will return the answer that it is not valid and the reason for the same. This makes it very easy to debug the issue and make the necessary correction.

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 UDF – User Defined Function to Strip HTML – Parse HTML – No Regular Expression The UDF used in the blog does fantastic task – it scans entire HTML text and removes all the HTML tags. It keeps only valid text data without HTML task. This is one of the quite commonly requested tasks many developers have to face everyday. De-fragmentation of Database at Operating System to Improve Performance Operating system skips MDF file while defragging the entire filesystem of the operating system. It is absolutely fine and there is no impact of the same on performance. Read the entire blog post for my conversation with our network engineers. Delay Function – WAITFOR clause – Delay Execution of Commands How do you delay execution of the commands in SQL Server – ofcourse by using WAITFOR keyword. In this blog post, I explain the same with the help of T-SQL script. Find Length of Text Field To measure the length of TEXT fields the function is DATALENGTH(textfield). Len will not work for text field. As of SQL Server 2005, developers should migrate all the text fields to VARCHAR(MAX) as that is the way forward. Retrieve Current Date Time in SQL Server CURRENT_TIMESTAMP, GETDATE(), {fn NOW()} There are three ways to retrieve the current datetime in SQL SERVER. CURRENT_TIMESTAMP, GETDATE(), {fn NOW()} Explanation and Comparison of NULLIF and ISNULL An interesting observation is NULLIF returns null if it comparison is successful, whereas ISNULL returns not null if its comparison is successful. In one way they are opposite to each other. Here is my question to you - How to create infinite loop using NULLIF and ISNULL? If this is even possible? 2008 Introduction to SERVERPROPERTY and example SERVERPROPERTY is a very interesting system function. It returns many of the system values. I use it very frequently to get different server values like Server Collation, Server Name etc. SQL Server Start Time We can use DMV to find out what is the start time of SQL Server in 2008 and later version. In this blog you can see how you can do the same. Find Current Identity of Table Many times we need to know what is the current identity of the column. I have found one of my developers using aggregated function MAX () to find the current identity. However, I prefer following DBCC command to figure out current identity. Create Check Constraint on Column Some time we just need to create a simple constraint over the table but I have noticed that developers do many different things to make table column follow rules than just creating constraint. I suggest constraint is a very useful concept and every SQL Developer should pay good attention to this subject. 2009 List Schema Name and Table Name for Database This is one of the blog post where I straight forward display script. One of the kind of blog posts, which I still love to read and write. Clustered Index on Separate Drive From Table Location A table devoid of primary key index is called heap, and here data is not arranged in a particular order, which gives rise to issues that adversely affect performance. Data must be stored in some kind of order. If we put clustered index on it then the order will be forced by that index and the data will be stored in that particular order. Understanding Table Hints with Examples Hints are options and strong suggestions specified for enforcement by the SQL Server query processor on DML statements. The hints override any execution plan the query optimizer might select for a query. 2010 Data Pages in Buffer Pool – Data Stored in Memory Cache One of my earlier year article, which I still read it many times and point developers to read it again. It is clear from the Resultset that when more than one index is used, datapages related to both or all of the indexes are stored in Memory Cache separately. TRANSACTION, DML and Schema Locks Can you create a situation where you can see Schema Lock? Well, this is a very simple question, however during the interview I notice over 50 candidates failed to come up with the scenario. In this blog post, I have demonstrated the situation where we can see the schema lock in database. 2011 Solution – Puzzle – Statistics are not updated but are Created Once In this example I have created following situation: Create Table Insert 1000 Records Check the Statistics Now insert 10 times more 10,000 indexes Check the Statistics – it will be NOT updated Auto Update Statistics and Auto Create Statistics for database is TRUE Now I have requested two things in the example 1) Why this is happening? 2) How to fix this issue? Selecting Domain from Email Address This is a straight to script blog post where I explain how to select only domain name from entire email address. Solution – Generating Zero Without using Any Numbers in T-SQL How to get zero digit without using any digit? This is indeed a very interesting question and the answer is even interesting. Try to come up with answer in next 10 minutes and if you can’t come up with the answer the blog post read this post for solution. 2012 Simple Explanation and Puzzle with SOUNDEX Function and DIFFERENCE Function In simple words - SOUNDEX converts an alphanumeric string to a four-character code to find similar-sounding words or names. DIFFERENCE function returns an integer value. The  integer returned is the number of characters in the SOUNDEX values that are the same. Read Only Files and SQL Server Management Studio (SSMS) I have come across a very interesting feature in SSMS related to “Read Only” files. I believe it is a little unknown feature as well so decided to write a blog about the same. Identifying Column Data Type of uniqueidentifier without Querying System Tables How do I know if any table has a uniqueidentifier column and what is its value without using any DMV or System Catalogues? Only information you know is the table name and you are allowed to return any kind of error if the table does not have uniqueidentifier column. Read the blog post to find the answer. Solution – User Not Able to See Any User Created Object in Tables – Security and Permissions Issue Interesting question – “When I try to connect to SQL Server, it lets me connect just fine as well let me open and explore the database. I noticed that I do not see any user created instances but when my colleague attempts to connect to the server, he is able to explore the database as well see all the user created tables and other objects. Can you help me fix it?” Importing CSV File Into Database – SQL in Sixty Seconds #018 – Video Here is interesting small 60 second video on how to import CSV file into Database. ColumnStore Index – Batch Mode vs Row Mode Here is the logic behind when Columnstore Index uses Batch Mode and when it uses Row Mode. A batch typically represents about 1000 rows of data. Batch mode processing also uses algorithms that are optimized for the multicore CPUs and increased memory throughput. Follow up – Usage of $rowguid and $IDENTITY This is an excellent follow up blog post of my earlier blog post where I explain where to use $rowguid and $identity.  If you do not know the difference between them, this is a blog with a script example.

  • Window Functions in SQL Server

    When SQL Server introduced Window Functions in SQL Server 2005, it was done in a rather tentative way, with only a handful of functions being introduced. This was frustrating, as they remove the last excuse for cursor-based operations by providing aggregations over a partition of the result set, and imposing an ordered sequence over a partition. Now, with SQL Server 2012, we are soon to enjoy a full range of Window Functions. They are going to make for some much simpler SQL queries.

  • SQL Server 2008 Express + Reporting Services on Windows 7

    - by TimothyP
    I'm trying to install SQL Server Express 2008 and Reporting Services on a x64 Windows 7 Machine for development purposes. I've installed SQL Server 2008 Express with the Microsoft Web Platform Installer I had to manually enable the SQL Server Browser in the Sql Server Configuration Manager and tried to enable the SQL Server Agent but that simply doesn't work. Keeps throwing an RPC error: "The remote procedure call failed. [0x800706be]". The start mode is set to Disabled and I cannot change it. Even though I selected the SQL Server Express with advanced services in the web platform installer I could not find any reference to SQL Server Reporting Services so I used the SQL Server Installation Center x64 application to "upgrade" to SQL Server Express 2008 with advanced services... this installed many things but still I couldn't find any reference to SQL Server Reporting Services other than an application called: "Reporting Services Configuration Manager" This opens up a dialog called "Reporting Services Configuration Connection" which is asking for a server name (shows the name of my machine) and a Find button. When I click the find button I get: "Unable to connect to the Reporting Server WMI provider. Details: Invalid Namespace". I found some references on the web to solve this problem, but they refer to a directory: "%ProgamFiles%\Microsoft SQL Server\MSRS10.SQL2008\Reporting Services\" which does not exist anywhere on my system. (The directories for SQL Server are there, but there is no Reporting Services directory anywhere). What am I doing wrong here? Wasn't the web platform installer supposed to handle all this? Thnx for any advice. PS: Most google results refer to 2005 vs 2008 problems, but I never had 2005 installed on this system, it's a newly installed development machine.

  • Remote Desktop to Server 2008R2 fails from one particular Win7 client

    - by Jesse McGrew
    I have a VPS running Windows Web Server 2008 R2. I'm able to connect using Remote Desktop from my home PC (Windows 7), personal laptop (Windows 7), and work laptop (Windows XP). However, I cannot connect from my work PC (Windows 7). I receive the error "The logon attempt failed" in the RDP client, and the server event log shows "An account failed to log on" with this explanation: Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: username Account Domain: hostname Failure Information: Failure Reason: Unknown user name or bad password.

The server is part of a domain but my account is local, so I'm logging in using a username of the form hostname\username. None of the clients are part of a domain. The server uses a self-signed certificate, and connecting from home I get a warning about that, but connecting from work I just get the logon error.

  • Windows Server 2008R2 Virtual Lab Activation strategies?

    - by William Hilsum
    I have a ESXi server that I use for testing, however, I am often needing to create additional Windows Server virtual machines. Typically, if I do not need a VM for more than 30 days, I simply do not activate. However, I have been doing a lot of HA/DRS testing recently and I have had a few servers up for more than this time. I have a MSDN account with Microsoft and have already received extra keys for Windows Server 2008 R2. I am doing nothing illegal and I am sure if I asked, they would issue more - but, I do not want to tempt fate! I have got 3 different "activated" windows snapshots I can get to at any time. If I try to clone these machines, I get the usual "did you copy or move them VM" message. If I choose copy, as far as I can see, it changes the BIOS ID and NIC MACs which is enough to disable activation. If I choose move, it keeps the activation fine (obviously, I know to change the NIC MAC - I believe I can leave the BIOS ID without problems). However, either of these options keeps the same SID code for the computer and user accounts. After the activation period has expired, as far as I can see, all that happens is optional updates do not work - it seems that the normal updates work fine. Based on this, as you can easily get in to Windows when not activated without any sort of workaround, I was wondering if it is ok just to leave a machine un activated? (However, I obviously would prefer if it was activated!) Alternatively, how dangerous is it run multiple machines on a non domain environment with the same SID? I am just interested to know if anyone can recommend a strategy for me? I have only found one solution that deals with bypassing activation - I am not interested in doing anything remotely dodgy... at a stretch, I am happy to rearm (I have never needed to keep a server past 100 days), but, I would rather have a proper strategy in place.

  • How to run VisualSvn Server on port 443 running IIS on same server?

    - by Metro Smurf
    Server 2008 R2 SP1 VisualSvn Server 2.1.6 The IIS server has about 10 sites. One of them uses https over port 443 with the following bindings: http x.x.x.39:80 site.com http x.x.x.39:80 www.site.com https x.x.x.39:443 VisualSvn Server Properties server name: svn.SomeSite.com server port: 443 Server Binding: x.x.x.40 No sites on IIS are listening to x.x.x.40. When starting up VisualSvn server, the following errors are thrown: make_sock: could not bind to address x.x.x.40:443 (OS 10013) An attempt was made to access a socket in a way forbidden by its access permissions. no listening sockets available, shutting down When I stop Site.com on IIS, then VisualSvn Server starts up without a problem. When I bind VisualSvn server to port 8443 and start Site.com, then VisualSvn Server starts without a problem. My goal is to be able to access the VisualSvn Server with a normal url, i.e., one that does't use a port number in the address: https://svn.site.com vs https://svn.site.com:8443 What needs to be configured to allow VisualSvn Server to run on port 443 with IIS running on the same server?

  • Moving Microsoft Exchange server to the private network.

    - by Alexey Shatygin
    In one of the offices, we have a 50-computers network, which had only one server machine: Windows 2003 Server Microsoft ISA Server Microsoft Exchange 2003 This server worked as a gateway (proxy server), mail server, file server, firewall and domain controller. It had two network interfaces, one for WAN (let's say 222.222.222.222) and one for LAN (192.168.1.1). I set up a Linux box to be the gateway (without a proxy), so the Linux box now has the following interfaces: 222.222.222.222 (our external IP, we removed it from the Windows machine) and 192.168.1.100 (internal IP), but we need to keep the old Windows server as a mail server and a proxy for some of our users, until we prepare another Linux machine for that, so I need the mail server on that machine to be available from the Internet. I set up iptables rules to redirect all the incoming connections on the 25th and 110th ports of our external IP to 192.168.1.1:25 and 192.168.1.1:110 and when I try to telnet our SMTP service telnet 222.222.222.222 25 I get the greetings from our windows server's (192.168.1.1) SMTP service, and that's works fine. But when I telnet POP3 service telnet 222.222.222.222 110 I only get the blank black screen and the connection seem to disappear if I press any button. I've checked the ISA rules - everything seems to be the same for 110th and 25th ports. When I telnet on 110th ports of our Windows server from our new gateway machine like this: telnet 192.168.1.1 110 I get the acces to it's POP3 service: +OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 (...) ready. What sould I do, to make the POP3 service available through our new gateway?

    - by tesmar
    Hi, I am new to Windows Server but have been given a copy of Standard R2. I want to use it on my old Desktop as a file server/ Time Machine like backup device. Is this possible? Is it possible to use it like Dropbox where I can sync a folder with it over the web (perhaps using DynDNS since I am on cable modem?) Sincerely, tesmar

  • Data Driven MSTest: DataRow is always null

    - by David Back
    I am having a problem using Visual Studio data driven testing. I have tried to deconstruct this to the simplest example. I am using Visual Studio 2012. I create a new unit test project. I am referencing system data. My code looks like this: namespace UnitTestProject1 { [TestClass] public class UnitTest1 { [DeploymentItem(@"OrderService.csv")] [DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "OrderService.csv", "OrderService#csv", DataAccessMethod.Sequential)] [TestMethod] public void TestMethod1() { try { Debug.WriteLine(TestContext.DataRow["ID"]); } catch (Exception ex) { Assert.Fail(); } } public TestContext TestContext { get; set; } } } I have a very small csv file that I have set the Build Options to to 'Content' and 'Copy Always'. I have added a .testsettings file to the solution, and set enable deployment, and added the csv file. I have tried this with and without |DataDirectory|, and with/without a full path specified (the same path that I get with Environment.CurrentDirectory). I've tried variations of "../" and "../../" just in case. Right now the csv is at the project root level, same as the .cs test code file. I have tried variations with xml as well as csv. TestContext is not null, but DataRow always is. I have not gotten this to work despite a lot of fiddling with it. I'm not sure what I'm doing wrong. Does mstest create a log anywhere that would tell me if it is failing to find the csv file, or what specific error might be causing DataRow to fail to populate? I have tried the following csv files: ID 1 2 3 4 and ID, Whatever 1,0 2,1 3,2 4,3 So far, no dice.

  • Why do not C++11's move constructor/assignment operator act as expected

    - by xmllmx
    #include <iostream> using namespace std; struct A { A() { cout << "A()" << endl; } ~A() { cout << "~A()" << endl; } A(A&&) { cout << "A(A&&)" << endl; } A& operator =(A&&) { cout << "A& operator =(A&&)" << endl; return *this; } }; struct B { // According to the C++11, the move ctor/assignment operator // should be implicitly declared and defined. The move ctor // /assignment operator should implicitly call class A's move // ctor/assignment operator to move member a. A a; }; B f() { B b; // The compiler knows b is a temporary object, so implicitly // defined move ctor/assignment operator of class B should be // called here. Which will cause A's move ctor is called. return b; } int main() { f(); return 0; } My expected output should be: A() A(A&&) ~A() ~A() However, the actual output is: (The C++ compiler is: Visual Studio 2012) A() ~A() ~A() Is this a bug of VC++? or just my misunderstanding?

  • Sql Server Compact Edition version error.

    - by Tim
    I am working on .NET ClickOnce project that uses Sql Server 2005 Compact Edition to synchronize remote data through the use of a Merge replication. This application has been live for nearly a year now, and while we encounter occasional synchronization errors, things run quite smoothly for the most part. Yesterday a user reported an error that I have never seen before and have yet to find any information for online. Many users synchronize every night, and I haven't received error reports from anyone else, so this issue must be isolated to this particular user / client machine. Here are the full details of the error: -Error Code : 80004005 -Message : The message contains an unexpected replication operation code. The version of SQL Server Compact Edition Client Agent and SQL Server Compact Edition Server Agent should match. [ replication operation code = 31 ] -Minor Error : 28526 -Source : Microsoft SQL Server Compact Edition -Numeric Parameters : 31 One interesting thing that I've found is that his data does get synchronized to the server, so this error must occur after the upload completes. I have yet to determine whether or not changes at the server are still being downloaded to his subscription. Thinking that maybe there was some kind of version conflict going on, I had a remote desktop session with this user last night and uninstalled both the application and the SQL Server Compact Edition prerequisite, then reinstalled both from our ClickOnce publication site. I also removed his existing local database file so that upon synchronization, an entirely new subscription would be issued to him. Still his errors continue. I suppose the error may be somewhat general, and the text in the error message stating that the versions should match may not necessarily reflect the problem at hand. This site contains the only official reference to this error that I've been able to find, and it offers no more detail than the error message itself. Has anyone else encountered this error? Or at least know more about SQL Compact to have a better guess as to what is going on here? Any help / suggestions will be greatly appreciated!

  • Using jQuery with Windows 8 Metro JavaScript App causes security error

    - by patridge
    Since it sounded like jQuery was an option for Metro JavaScript apps, I was starting to look forward to Windows 8 dev. I installed Visual Studio 2012 Express RC and started a new project (both empty and grid templates have the same problem). I made a local copy of jQuery 1.7.2 and added it as a script reference. <!-- SomeTestApp references --> <link href="/css/default.css" rel="stylesheet" /> <script src="/js/jquery-1.7.2.js"></script> <script src="/js/default.js"></script> Unfortunately, as soon as I ran the resulting app it tosses out a console error: HTML1701: Unable to add dynamic content ' a' A script attempted to inject dynamic content, or elements previously modified dynamically, that might be unsafe. For example, using the innerHTML property to add script or malformed HTML will generate this exception. Use the toStaticHTML method to filter dynamic content, or explicitly create elements and attributes with a method such as createElement. For more information, see http://go.microsoft.com/fwlink/?LinkID=247104. I slapped a breakpoint in a non-minified version of jQuery and found the offending line: div.innerHTML = " <link/><table></table><a href='/a' style='top:1px;float:left;opacity:.55;'>a</a><input type='checkbox'/>"; Apparently, the security model for Metro apps forbids creating elements this way. This error doesn't cause any immediate issues for the user, but given its location, I am worried it will cause capability-discovery tests in jQuery to fail that shouldn't. I definitely want jQuery $.Deferred for making just about everything easier. I would prefer to be able to use the selector engine and event handling systems, but I would live without them if I had to. How does one get the latest jQuery to play nicely with Metro development?

  • Authentication Problem in Silverlight - Cannot connect to SQL Server

    - by Johann
    Hi All, At the moment, when I try to register a user using the default Business Template in Silverlight, I am getting an error. Basically I am following a tutorial found on Channel 9 on how to build a business app with Silverlight. "An error has occurred while establishing a connection to the server. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 5) An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 1326)". I found a blog where it identifies the problem, and followed every step, however I am still getting the same problems. Here is my connection string:- <add name="SIEventManagerEntities" connectionString="metadata=res://*/EventManagerDBModel.csdl|res://*/EventManagerDBModel.ssdl|res://*/EventManagerDBModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MONFU-PC;Initial Catalog=SIEventManager;Integrated Security=SSPI;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> Any help would really be very much appreciated! Thanks

  • SQL SERVER – T-SQL Errors and Reactions – Demo – SQL in Sixty Seconds #005 – Video

    - by pinaldave
    We got tremendous response to video of Error and Reaction of SQL in Sixty Seconds #002. We all have idea how SQL Server reacts when it encounters T-SQL Error. Today Rick explains the same in quick seconds. After watching this I felt confident to answer talk about SQL Server’s reaction to Error. We received many request to follow up video of the earlier video. Many requested T-SQL demo of the concept. In today’s SQL in Sixty Seconds Rick Morelan has presented T-SQL demo of very visual reach concept of SQL Server Errors and Reaction. More on Errors: Explanation of TRY…CATCH and ERROR Handling Create New Log file without Server Restart Tips from the SQL Joes 2 Pros Development Series – SQL Server Error Messages I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can.

  • Problems with self-signed SSL certificate for SSTP in Windows Server Foundation 2008

    - by John Barton
    I am trying to configure SSTP in Windows Server Foundation 2008. I want to use a self-signed SSL certificate to do authentication. When the server is running, I get the following error when trying to connect: 0x800B0109: A certificate chain processed, but terminated in a root certificate that is not trusted by the trust provider. I created the self-signed certificate in the IIS "Server Certificates" panel. From that panel, I exported the certificate, with the private key, to a .pfx file. I installed this certificate on the client computer which I tried to connect from. The certificate bound to the SSL listener in the RRAS-Security panel is present in the Trusted Root Certificate Authority stores on both machines. I've been getting super annoyed setting up certificates. Any advice here?

  • SQL SERVER – DMV – sys.dm_exec_query_optimizer_info – Statistics of Optimizer

    - by pinaldave
    Incredibly, SQL Server has so much information to share with us. Every single day, I am amazed with this SQL Server technology. Sometimes I find several interesting information by just querying few of the DMV. And when I present this info in front of my client during performance tuning consultancy, they are surprised with my findings. Today, I am going to share one of the hidden gems of DMV with you, the one which I frequently use to understand what’s going on under the hood of SQL Server. SQL Server keeps the record of most of the operations of the Query Optimizer. We can learn many interesting details about the optimizer which can be utilized to improve the performance of server. SELECT * FROM sys.dm_exec_query_optimizer_info WHERE counter IN ('optimizations', 'elapsed time','final cost', 'insert stmt','delete stmt','update stmt', 'merge stmt','contains subquery','tables', 'hints','order hint','join hint', 'view reference','remote query','maximum DOP', 'maximum recursion level','indexed views loaded', 'indexed views matched','indexed views used', 'indexed views updated','dynamic cursor request', 'fast forward cursor request') All occurrence values are cumulative and are set to 0 at system restart. All values for value fields are set to NULL at system restart. I have removed a few of the internal counters from the script above, and kept only documented details. Let us check the result of the above query. As you can see, there is so much vital information that is revealed in above query. I can easily say so many things about how many times Optimizer was triggered and what the average time taken by it to optimize my queries was. Additionally, I can also determine how many times update, insert or delete statements were optimized. I was able to quickly figure out that my client was overusing the Query Hints using this dynamic management view. If you have been reading my blog, I am sure you are aware of my series related to SQL Server Views SQL SERVER – The Limitations of the Views – Eleven and more…. With this, I can take a quick look and figure out how many times Views were used in various solutions within the query. Moreover, you can easily know what fraction of the optimizations has been involved in tuning server. For example, the following query would tell me, in total optimizations, what the fraction of time View was “reference“. As this View also includes system Views and DMVs, the number is a bit higher on my machine. SELECT (SELECT CAST (occurrence AS FLOAT) FROM sys.dm_exec_query_optimizer_info WHERE counter = 'view reference') / (SELECT CAST (occurrence AS FLOAT) FROM sys.dm_exec_query_optimizer_info WHERE counter = 'optimizations') AS ViewReferencedFraction Reference : Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, PostADay, SQL, SQL Authority, SQL DMV, SQL Optimization, SQL Performance, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, SQLServer, T SQL, Technology
