  • How to implement SHA-2 in SQL Server 2005 or 2008 with a CLR assembly

    SQL Server 2012 supports SHA-256 and SHA-512 through the HASHBYTES() function, but earlier versions of SQL Server do not. SHA-256, SHA-384 and SHA-512 can, however, be implemented in SQL Server 2005 or SQL Server 2008 with the CLR assembly described in this article. Optimize SQL Server performance“With SQL Monitor, we can be proactive in our optimization process, instead of waiting until a customer reports a problem,” John Trumbul, Sr. Software Engineer.

  • Methodology for Documenting Existing Code Base

    - by George Stocker
    I work as part of a team on an existing application that has no inline documentation, nor does it have technical documentation. As I've been working on various bug reports on the application, I've written a sort of breadcrumb trail for myself - bug numbers in various places so that the next developer can refer to that bug number to see what was going on. My question is thus: What is the most effecient method for documenting this code? Should I document as I touch the area (the virus method, if you will), or should I document from each section on its own, and not follow paths that branch out into other areas of the application? Should I insert inline comments where none previously existed (with the fear that I may end up incorrectly identifying what the code does)? What method would you use to accurately and quickly document a rather large application that has no existing inline documentation, nor inline references to external documentation?

  • Avoid SQL Injection with Parameters

    - by simonsabin
    The best way to avoid SQL Injection is with parameters. With parameters you can’t get SQL Injection. You only get SQL Injection where you are building a SQL statement by concatenating your parameter values in with your SQL statement. Annoyingly many TSQL statements don’t take parameters, CREATE DATABASE for instance, or really annoyingly ALTER USER. In these situations you have to rely on using QUOTENAME or REPLACE to avoid SQL Injection. (Kimberly Tripp takes about this in her recent blog post Little...(read more)

  • ASP.NET Session State SQL Server 2008 R2 Freezes with High CPU Usage

    - by jtseng
    Our ASP.Net website uses SQL Server as the session state provider. We currently host the database on SQL Server 2005 since it does not play well on 2008 R2. We would like to know why, and how to fix it. hardware setup Our current session state server has SQL Server 2005 with the files hosted on a single local disk. It is one of our oldest servers since it has served us well, and we never felt the need to upgrade it. The database is about 2 GB holding 6000 sessions. (The sessions are a little big, but we need it.) We have another server with SQL Server 2008 R2 with a much faster CPU, much more RAM, and a much faster hard disk. situation One day, we have a huge surge in traffic. The transaction log growth on SQL Server freezes the server for 10's of seconds, allowing only a few requests through in minutes. So we load up the new server with ASPState with very large data and log files and point all of our applications to the new server. It chugs along fine for about 5 minutes, and then the CPU usage jumps up to 50% of the 16 cores that Standard Edition can use and freezes for 10's of seconds at a time. The files do not record any autogrowth events. The disk queue is nice and low. RAM usage is low. CPU usage on our old server has never been higher than 5%. What happened on the new server? Alternatively, I would like to hear success stories with ASP.NET session state server running on SQL Server 2008 R2 with an average write load of 30MB/sec with bursts up to 200MB/sec.

  • keeping connection open all time in sql

    - by Costi
    I have developed a Windows application in c# in which multiple users can add some numbers and their name and can view the data entered. The problem that I have is that the sever is on my laptop and every time I log off or close my laptop, they are losing connection to the DB and can not add or view any more. It seems that the port is closed or something. Is there a way to keep the port and their connection established all the time even when I'm logging out?

  • SQL Server 2005 SE SP3 on Windows Server 2008 R2 x64 premature query disconnections

    - by southernpost
    New Dell PowerEdge R910, 4x8 Intel X7560, 192GB RAM, hardware NUMA, local RAID, Broadcom NetExtreme II multiport NIC, unteamed, TCP Offload disabled, RSS disabled, NetDMA disabled, Hyperthreading disabled. SQL Server 2005 SE x64 SP3 on Windows Server 2008 R2 EE x64. No other apps on server. Max Mem = 180GB, Max DOP = 4. Existing Windows Server 2003 R2 EE x64 app server connecting to Dell via firewall using SQL Authenticated logins. Symptoms: Intermittent errors at the app server: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.) Findings: Running queries from SSMS located on another machine within the same domain as the SQL Server run without error. SQLIO showed good performance. Windows and SQL logs show no related messages. Microsoft reveiwed PssDiag trace and stated that "We are not seeing timeouts from SQL Side. The queries bring run against the database are timing out within 9secs. This is a database connectivity error." "we can also see from the AttnSeq column that we are also not seeing any Attentions from the SQL Side.". Dell has confirmed that we are using the latest Broadcom drivers.

  • How to create an alias for a named SQL Server instance

    - by Svish
    On my developer computer I have an SQL Server instance named *developer_2005*. In the resource setting files of a C# application we are creating, the instance name is set to foobar (not really, but just as an example). So when I run the application (in debug or realease) it tries to connect to an SQL Server on localhost, named foobar. I am wondering if it is possible to create an alias or something like that, so that the application actually finds an SQL Server on localhost named foobar, but it is actually connecting to the instance named *developer_2005*. The connection string in the config file of the application is Data Source=localhost\foobar;Initial Catalog=barfoo;Integrated Security=True with provider name System.Data.SqlClient. If I change localhost\foobar to *localhost\developer_2005* then the application can connect like it should. How can I create an alias so that I won't have to change the string in the file? I tried, in SQL Server Management Studio, to create a Server Registration with registered server name "localhost\developer", but this didn't seem to do any good. Not even sure what that really did... But then I discovered SQL Server Configuration Manager\SQL Native Client COnfiguration\Aliases. And I kind of assume this is where the solution lies. But I can't quite figure out how to add a new one... When creating a new one, I have to provide Alias Name, Port No, Protocol and Server, and I don't really have a clue what to put in either of them.

  • Do I need to disable access to a publisher database when setting up SQL Server 2000 Transactional Re

    - by Kev
    I have a production database i.e. where there are constant updates and I've configured this to be published to another server using Transactional Replication. When I configure transactional replication I've been doing the following: disable access to the source database backup source DB then restore to subscription server configure replication re-enable DB access to our apps The problem with this approach is scheduling in downtime, having to suspend all the various timed scheduled tasks we run and shutting down access to our various applications that are dependant on this database. Can I just configure transactional replication without disabling access to the publishing database and the subscriber database will correctly catch up? i.e. are all the DML statements queued on the publisher and as soon as the subscriber is ready they are picked off and executed?

  • Select Data From XML in MS SQL Server (T-SQL)

    - by Doug Lampe
    So you have used XML to give you some schema flexibility in your database, but now you need to get some data out.  What do you do?  The solution is relatively  simple:   DECLARE @iDoc INT /* Stores a pointer to the XML document */ DECLARE @XML VARCHAR(MAX) /* Stores the content of the XML */   set @XML = (SELECT top 1 Xml_Column_Name FROM My_Table where Primary_Key_Column = 'Some Value')   EXEC sp_xml_preparedocument @iDoc OUTPUT, @XML   SELECT * FROM OPENXML(@iDoc,'/some/valid/xpath',2)                      WITH (output_column1_name varchar(50)  'xml_node_name1',                                                     output_column2_name varchar(50)  'xml_node_name2')   EXEC sp_xml_removedocument @iDoc   In this example, the XML data would look something like this:   <some>   <valid>     <xpath>       <xml_node_name1>Value1</xml_node_name1>       <xml_node_name2>Value2</cml_node_name2>     </xpath>   </valid> </some>   The resulting query should give you this:   output_column1_name    output_column2_name ------------------------------------------ Value1                 Value2   Note that in this example we are only looking at a single record at a time.  You could use a cursor to iterate through multiple records and insert the XML data into a temporary table.

  • SQL DB design to support user feeds (in application like facebook)

    - by Yoav
    I have a social network server with a MySql DB. I want to show the users feeds like done in Facebook. Example - UserX now Friend with userY, userX did like on postX etc. Currently I have table: C1 : UserId C2 : LogType (now friend, did like etc) C3 : ObjectId (Can be userId or postId) - set depending on the LogType. Currently to get all related logs to show to the user I do the following queries: 1. Get All user Friends userIds 2. Query all rows which C1 is in userIds (I query completed) 3. Scan the DB and see - if LogType equals DidLike, check if post's OwnerId is the userId - if yes add it to logs. And so on. Obvious this is not efficient at all. I am looking for a better way. I thought I had in mind: Create a new table (in addition to the Log table) C1 : UserId C2 : LogId (from Log table) C3 : UserID of the one who did the action When querying logs - look in the table and get related Logs (by LogId) from LogTable. Updating the table: Whenever user doing action that should be in the log: 1. Add the Log entry to LogTable. 2. Scan the DB and see which users are interested with the Log (Who my friends are, Who is the owner of the post) and add related entries to the new table. (must be done in BG). 3. If user UNFRIEND another user - then look in the logs for all rows where C3 == UNFRIENDED user id and delete them. Any opinions? Other suggestions?

  • My coworker created a 96 columns SQL table

    - by Eric
    Here we are in 2010, software engineers with 4 or 5 years or experience, still designing tables with 96 fracking columns. I told him it's gonna be a nightmare. I showed him that we have to use ordinals to interface MySQL with C#. I explained that tables with more columns than rows are a huge smell. Still, I get the "It's going to be simpler this way". What should I do? EDIT * This table contains data from sensors. We have sensor 1 with Dynamic_D1X Dynamic_D1Y [...] Dynamic_D6X Dynamic_D6Y [...]

  • ClearTrace for SQL Server 2012

    - by Bill Graziano
    I’ve updated the beta for ClearTrace that support SQL Server 2012.  This requires SQL Server 2012 to be installed on the computer where ClearTrace is running.  It will read traces from SQL Server 2008 R2, SQL Server 2008 and SQL Server 2005. It includes some minor improvements in performance and handling large SQL statements. It should also give better errors. If you do find any of those errors, please report them in the support forum.

  • Foreign key restrictions -> yes or no?

    - by This is it
    I would like to hear some”real life experience” suggestions if foreign key restrictions are good or bad thing to enforce in DB. I would kindly ask students/beginners to refrain from jumping and answering quickly and without thinking. At the beginning of my career I thought that stupidest thing you can do is disregard the referential integrity. Today, after "few" projects I'm thinking different. Quite different. What do you think: Should we enforce foreign key restrictions or not? *Please explain your answer.

  • Can’t connect to SQL Server 2008 - looks like Shared Memory problem

    - by Proposition Joe
    I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio. I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) Why is it returning a Named Pipes error? Why would it not just use Shared Memory, as this has a higher priority order in the list of connection protocols? It seems like it is not listening on Shared Memory for some reason? When I set Named Pipes to enabled and try to connect, I get the same error message. My windows account is does not have administrator priviliges on my computer - perhaps this is making a difference in some way (as some of the discussions in this post about an "SuperSocketNetLib\Lpc" registry key seems to suggest). I have tried restarting the SQL Server service, by the way, and also tried to get someone to log onto the machine with an admin account to restart the SQL Server service. Still no luck.
