  • Microsoft PowerPivot for Excel 2010 – book coming in September

    - by Marco Russo (SQLBI)
    As you might already know, I and Alberto Ferrari are writing a book about PowerPivot 2010 for Excel. The official title is Microsoft PowerPivot for Excel 2010: Give Your Data Meaning and you can already order it on Amazon ! However, it will be published in September 2010, and it is reasonable considered we are still in writing mode… Well, before buying it, consider that we are writing the book for the “real user” of PowerPivot, who doesn’t have a knowledge of MDX, multidimensional databases, ETL,...(read more)

  • Surface RT–first impressions

    - by DigiMortal
    Couple months ago I bought Surface RT because I needed some lightweight business supporting thing to take with me sometimes. Carrying ~3kg development laptop is not always fun, specially when you have long days and you need to move from one place to another often. Surface RT turned out to be pretty good investment and here are my first real-life experiences. Read more from my new blog @ gunnarpeipman.com

  • T-SQL Tuesday #13: Clarifying Requirements

    - by Alexander Kuznetsov
    When we transform initial ideas into clear requirements for databases, we typically have to make the following choices: Frequent maintenance vs doing it once. As we are clarifying the requirements, we need to determine whether we want to concinue spending considerable time maintaining the system, or if we want to finish it up and move on to other tasks. Race car maintenance vs installing electric wiring is my favorite analogy for this kind of choice. In some cases we need to sqeeze every last bit...(read more)

  • Master database Compatibility level after an In-place Upgrade

    - by Jonathan Kehayias
    Yesterday a forums member asked why sys.dm_exec_sql_text() wouldn’t work on one instance of SQL where he was a sysadmin while the same code worked correctly on another instance of SQL.  The initial thought was that it was some kind of permissions issue.  Ken Simmons ( blog / twitter ) pointed out that the compatibility level of the database would affect the ability to use this DMF and that running it from a database at 80 compatibility would fail.  It turns out the person was running...(read more)

  • Learning PostgreSql: bulk loading data

    - by Alexander Kuznetsov
    In this post we shall start loading data in bulk. For better performance of inserts, we shall load data into a table without constraints and indexes. This sounds familiar. There is a bulk copy utility, and it is very easy to invoke from C#. The following code feeds the output from a T-SQL stored procedure into a PostgreSql table: using ( var pgTableTarget = new PgTableTarget ( PgConnString , "Data.MyPgTable" , GetColumns ())) using ( var conn = new SqlConnection ( connectionString )) { conn.Open...(read more)

  • jQuery: Novice to Ninja

    <b>A Million Chimpanzees:</b> "Who should read this book?

  • How to: group by month with SQL

    - by AngelEyes
    I took this particular code from http://weblogs.sqlteam.com/jeffs/archive/2007/09/10/group-by-month-sql.aspx, a good read. Shows you what to avoid and why.   The recommended technique is the following:   GROUP BY dateadd(month, datediff(month, 0, SomeDate),0)   By the way, in the "select" clause, you can use the following:   SELECT         month(dateadd(month, datediff(month, 0, SomeDate),0)) as [month],         year(dateadd(month, datediff(month, 0, SomeDate),0)) as [year],   Just remember to also sort properly if needed:   ORDER BY dateadd(month, datediff(month, 0, SomeDate),0)

  • JavaOne 2012 Call for Papers

    - by Tori Wieldt
    JavaOne 2012 is happening Sept. 30-Oct 4 in San Francisco. The Call For Papers for this conference is now open. Java Evangelist Arun Gupta, who was on one of the selection committees and will be again this year, provided some great tips for submission (and a peek into the submission process): JavaOne is a technology-focused conference so any product, marketing or seemingly marketish talk are put at the bottom of the list. Oracle Open World and Oracle Develop are better options for submitting product specific talks. Make your title catchy. Remember the attendees are more likely to read the abstract if they like the title. We try our best to recategorize the talk to a different track if it needs to but please ensure that you are filing in the right track to have all the right eyeballs looking at it. Also, it does not hurt marking an alternate track if your talk meets the criteria. Make sure to coordinate within your team before the submission - multiple sessions from the same team or company does not ensure that the best speaker is picked. In such case we rely upon your "google presence" and/or review committee's prior knowledge of the speaker. The reviewers may not know you or your product at all and you get 750 characters to pitch your idea. Make sure to use all of them, to the last 750th character. Make sure to read your abstract multiple times to ensure that you are giving all the relevant information ? Think through your presentation and see if you are leaving out any important aspects. Also look if the abstract has any redundant information that will not required by the reviewers. There are additional sections that allow you to share information about the speaker and the presentation summary. Use them to blow the horn about yourself and any other relevant details. Please don't say "call me at xxx-xxx-xxxx to find out the details." :-) The tracks this year are: Core Java Platform Development Tools and Techniques Emerging Langauges on the JVM Enterprise Services Architectures and the Cloud Java EE Web Profile and Platform Technologies Java ME, Java Card, Embedded, and Devices Java FX and Rich User Experiences IMPORTANT: Submit your proposal as soon as possible, the the Call for Papers closes April 9th, a mere three weeks away!  Follow these channels to get the latest news about #JavaOne 2012.  originally posted on blogs.oracle.com/javaone

New release delivers key capabilities designed to help organizations improve customer experiences in order to increase customer acquisition and retention, while reducing total cost of ownership. Part of the Oracle Cloud, Oracle RightNow CX Cloud Service now integrates Oracle RightNow Chat Cloud Service with Oracle Engagement Engine Cloud Service, helping organizations intelligently and proactively engage with customers through the right channel at the right time.

    - by shantanu
    According to debian control file ant package's dependency list is: Depends: default-jre-headless | java2-runtime-headless | java5-runtime-headless | java6-runtime-headless, libxerces2-java That means it depends on default-jre-headless or java2-runtime-headless or java5-runtime-headless or java6-runtime-headless. But how could i determine that which package need to select as dependency? Note: I am trying to develop a package manager. I can not use provided package because they read sources.list file from a specific directory.

    I have been teaching in the past few weeks many people on how to use Entity Framework. I have decided to provide some of the samples I am using in my classes. First let’s try to define what EF is and why it is going to help us to create easily data-centric applications.Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework.EF addresses the problem of Object-relational impedance mismatch . I will not be talking about that mismatch because it is well documented in many...(read more)

  • Change CSS EMs to Percentage Automatically.

    - by Zachary Brown
    I cheated on a small site I was working on and used a site builder (Web Dwarf by Virtual Mechanics) to save time. I didn't realize it at the time, but this builder specifies the width, height and positions using CSS EMs. Is there an automated tool out there that will read through the CSS and convert each EM to a percentage so it will display correctly on wide screens as well? Any help would be great! Thanks. Here is the CSS: http://pastebin.de/14055

  • Deprecate UPDATE FROM? Not if I can help it!

    - by AaronBertrand
    Fellow MVP Hugo Kornelis ( blog ) has suggested that the proprietary UPDATE FROM and DELETE FROM syntax, which has worked for several SQL Server versions, should be deprecated in favor of MERGE. Here is the Connect item he raised: #332437 : Deprecate UPDATE FROM and DELETE FROM As you can see, the response is quite divided (more so than any other item that I can recall) - at the time of writing, it was 11 up-votes and 12 down-votes. I have no shame in admitting that I am one of the people who down-voted...(read more)

  • Time to Check Your Servers

    - by fatherjack
    Do you know how to find the time that your SQL Server started? Since SQL Server 2008 you can use: SELECT sqlserver_start_timeFROM sys.dm_os_sys_info On one of my servers this gives me: This is great, and can be used in lots of ways. I happened across the [sys].[dm_exec_requests]view the other day and out of curiosity ran the query SELECT MIN(start_time) AS [start time]FROM [sys].[dm_exec_requests] AS der And I was surprised to see the result as: Almost exactly an hour different.

    The skill set needed by a DBA can be quite diverse at times and a run in with SSRS 2005 probably illustrates the point quite well. I don't have skills in IIS although I was responsible for the design and deployment of an online mortage application site some years ago.I had to get hands on with IIS5, firewalls, intrusion systems, ISA Server, dmzs, NAT, IP and lots of other acronyms so I have an understanding of these things but never had to do anything other than set up and configure IIS - no...(read more)
