  • Help on choosing which SQL Server 2008 scale-out solution to pick (replication, ...)

    - by usr
    I am currently crossing the jungle of SQL Server scale-out technologies like replication, log-shipping, mirroring... I have the following constraints on my choice: I want the read-only load to be spread accross the primary and the secondary (mirror, subscriber) server Write load can be sent directly to the primary server The solution should be nearly maintainance free. Schema changes should just replicate to the secondary server (attention: replication has some serious constraints here as it seems) Written data should be accessible very quickly (in under 1s, but better would be instantaneously) on the secondary server On server failure I can tollerate up to one hour of data loss easily. I am more concerned with easy scalability Here are some options for what I could pick: http://msdn.microsoft.com/en-us/library/bb510414.aspx. Any experience you could share?

  • Interview Q: given an array of numbers, return array of products of all other numbers (no division)

    - by polygenelubricants
    I was asked this question in a job interview, and I'd like to know how others would solve it. I'm most comfortable with Java, but solutions in other languages are welcome. Given an array of numbers, nums, return an array of numbers products, where products[i] is the product of all nums[j], j != i. Input : [1, 2, 3, 4, 5] Output: [(2*3*4*5), (1*3*4*5), (1*2*4*5), (1*2*3*5), (1*2*3*4)] = [120, 60, 40, 30, 24] You must do this in O(N) without using division.

  • Why is [date] + [time] non-deterministic in SQL Server 2008?

    - by John Gietzen
    I'm trying to do the following for my IIS logs table: ALTER TABLE [W3CLog] ADD [LogTime] AS [date] + ([time] - '1900-01-01') PERSISTED However, SQL Server 2008 tells me: Computed column 'LogTime' in table 'W3CLog' cannot be persisted because the column is non-deterministic. The table has this definition: CREATE TABLE [dbo].[W3CLog]( [Id] [bigint] IDENTITY(1,1) NOT NULL, ... [date] [datetime] NULL, [time] [datetime] NULL, ... ) Why is that non-deterministic? I really need to index that field. The table currently has 1598170 rows, and it is a pain to query if we can't do an index seek on the full time. Since this is being UNION'd with some other log formats, we can't very easily just use the two columns separately.

  • How to make a staging table in ms sql 2005?

    - by chobo2
    Hi I heard about doing staging tables and I am wondering how you actually do it. I want to do a sqlbulk copy into a staging table. Then then update the real table. I heard in mssql 2008 that you can use something called merge but I am using ms sql 2005 so I heard I have to use a update inner join? I am not sure how that would look like(I am guessing best way would be to write it in SP). Also the staging table needs to be able to handle concurrent updates. I was thinking of putting another column in the staged as GUID so that way I know which records belong to which group and when it is time to delete the records from the staged table I can just use that. So can anyone show me any examples or tutorials on how to do it? Also how fast is this way? Say if your updating 50,000 records how long would that take(a guesstimate is fine)

  • using remote MS Access database which connects to remote SQL server

    - by Manjot
    Hi, We have a Microsoft Access database + application (on Server A) which connects to a remote SQL server (Server B) using System DSN ODBC connection (on Server A) to the SQL database server. The users are open this Access database remotely as it is on a shared location on the server A. They still have to create a local ODBC connection on their computers to connect to Server B. Is there anyway that they can access the Access database and not have to create a local ODBC connection? thanks in advance

  • Performance issues concurrently running MySQL and MS SQL Sever

    - by pacifika
    We're considering installing MySQL on the same database server that has been running MS SQL Server. From my research there are no technical issues running both concurrently, but I am worried that the performance will be affected. Is by default SQL Server set up to use all available memory for example? What should I look out for? Thanks

  • Which SQL Server version to install on Windows Server 2008 R2

    - by Dan
    We have a test server running Windows Server 2008 R2 that I want to put SQL Server 2008 onto. I have an MSDN subscription and thought I could install (x64 version) SQL2008 but the installation warned me this wasn't compatible with this version of windows (reporting that I am running Windows 7). When I log onto my MSDN to download an update the only SQL Server R2 options I have are for Express edition or Enterprise evaluation (I am logged in to subscriber downloads). Is there no standard R2 edition or am I missing something?

  • Error configuring SQL Reporting Services 2005 on Windows 7

    - by Omu
    I've installed SQL Server 2005 with Reporting Services on Windows 7 Ultimate x64 and when I try to configure it when clicking on "Windows Service Identity" I get this error message: There was an error while switching panels. The most likely cause is an error retrieving WMI properties. The exception details are: InvalidArgument=Value of '1' is not valid for 'SelectedIndex'. Parameter name: SelectedIndex Here is a screenshot: EDIT: This problem disappeared after I installed SP3 for SQL Server. I have problems on the next panes though.

  • Best practice for setting up SQL server on a Virtual Machine

    - by CrazyCoderz
    This is my first attempt at virtualizing SQL server on VMWare and I want to make sure I am doing things correctly. Should I have SQL server installed on the C: drive / same partition as the OS, Then add a virtual disk for the Data files, say 300GB, and then another virtual disk for the log files say 100GB? Or should I add 2 300GB vdisks, for the data files mirror them in the operating system, and then add a non mirrored vdisk of 100GB for LogFiles??

  • Managing MS SQL Server 2005/8 with third-party tools

    - by Craig
    I am trying to access a SQL Server database housed on a ISP. Normally one would simply install an express version of SQL server and use the Management Studio therein. Yeah, not me! Are there any third party tools that will allow me to manage my database? Lightweight ones would be the best but I'm not that picky. :)
