  • Review of the book SQL Server 2012 Reporting Services Blueprints

    Recently I had the opportunity to read the book SQL Server 2012 Reporting Services Blueprints written by Marlon Ribunal and Mickey Stuewe and published by Packt Publishing.

    First, I have to tell you that I am not a Reporting Services guy, I have much more knowledge on other topics such as Database Development, Performance Tuning, and so on. When I have heard about the opportunity to read this book I have thought it was a great opportunity to increase my knowledge on SQL Server Reporting Services, but the time is always short, so I needed a practical book that goes to the point quickly.

    If I would describe you the book with only one adjective, absolutely I could tell you that this book is concrete and easy to read. There are many pictures in the book and the authors guide the reader, step-by-step, from the Definition of the Data Source for an SSRS Project up to the Reporting Services Best Practices and Transactional Replication topics.

    The book covers all feature of SQL Server Reporting Services and provides you all information you need to start develop database reports with SSRS in a week. If you want to look inside the book you can download a sample chapter here and this is the table of contents:

    • Chapter 1: Let's Breakdown the Numbers
    • Chapter 2: Making a Good Impression
    • Chapter 3: Getting Some Actions
    • Chapter 4: Everything Looks Better with Charts
    • Chapter 5: Location, Location, Locations!
    • Chapter 6: Let's Get Analytical!
    • Chapter 7: Sir, We're Ready to Deploy!
    • Chapter 8: Beyond the Horizon!
    • Appendix A: SSRS Best Practices
    • Appendix B: Transactional Replication for Reporting Services

    My preferred chapters are the 2, 4 and 5.

    This book cannot missing in your digital or physical library!

  • Building Your T-SQL Tool Kit: Window Function Fundamentals

    The session Building Your T-SQL Tool Kit: Window Function Fundamentals by Christina E. Leo (@christinaleo) has been published on channel SQLPASS TV.

    Abstract

    Have you pulled a script to identify duplicates from a blog post but couldn't quite get it to work because you weren't sure what that ROW_NUMBER() function was doing? Maybe you heard talk about creating running totals without using subqueries, but you got frustrated when the groups weren't totaling correctly. Or maybe, you've never even heard of window functions. All are good reasons to attend this all-demo session, which demystifies this versatile T-SQL tool. First, we'll break apart the OVER clause, the key to understanding how window functions work. Then we'll expand on each group of functions that can use the OVER clause: ranking, aggregate, and analytic functions. Finally, we'll look at real scenarios where this tool works and talk about performance considerations. When you leave, you'll have the fundamentals you need to fully develop your mastery of window functions.

    Enjoy!

  • Automate Your ETL Infrastructure with SSIS and PowerShell

    SQLPASS TV channel has been published the session Automate Your ETL Infrastructure with SSIS and PowerShell that Allen White (@SQLRunr) has done during the PASS Summit 2013. 

    Abstract

    Much of your ETL process flow consists of packages that are very similar in structure, capturing data from a single source and transferring that to a single destination. Creating the individual packages can be tedious, and it’s easy to miss something in the process of generating the same basic package over and over again. BI Markup Language makes it easy to build new packages, and PowerShell makes creating the BIML scripts easy. In this session, we’ll see how you can use PowerShell to generate dozens of SSIS packages doing similar tasks from a defined set of ETL sources.

  • PASS DW/BI Virtual Chapter Upcoming Sessions (December 2013)

    Let me point out the upcoming live events scheduled for December 2013 organized by PASS Business Intelligence Virtual Chapter.

     

    Create and Load a Staging Environment from Scratch in an Hour with Biml

    Date: Thursday 12 December Noon PST / 3 PM EST / 8 PM GMT
    Speaker: Scott Currie
    URL: https://attendee.gotowebinar.com/register/7424713205660411905

    Business Intelligence Markup Language (Biml) automates your BI patterns and eliminates the manual repetition that consumes most of your SSIS development time. During this hour long presentation, Scott Currie from Varigence will use the free BIDSHelper add-in for BIDS and SSDT to introduce Biml and use to automatically generate large quantities of custom SSIS packages. The session will be largely demonstration driven, and reusable sample code will be distributed for you to use in your own projects. Using a live-typing approach, Scott will start from scratch and by the end of the session create a full-blown staging environment. This will include the creation of *hundreds* of target table creation scripts, data load packages, data scrubbing rules, logging, and more. The best part is that you can freely reuse the code in your own environment just by changing the connection strings - or make small changes to implement your own data load patterns.

     

    Inferred Dimension Members within MDS and SSIS

    Date: Monday 16 December 3 PM PST / 6 PM EST / 11 PM GMT
    Speaker: Reza Rad
    URL: https://attendee.gotowebinar.com/register/7123625140094491905

    Combining Master Data Services with Data Warehouses, will cause some challenges in ETL Scenarios. In this session we will go through a demo of Inferred Dimension Members implementation with SSIS considering the fact that MDS keeps the single version of truth for the dimension record. In this session you will learn how we will write back new record's data into MDS entity as an Inferred member. The staging structure of Master Data Services and Batch Processing will be used for this. Then you will learn what is the best practice to add the inferred record into Data Warehouse dimension. Updating the existing dimension member also would consider the Inferred member and apply SCD types only if this is not an inferred Member.

     

    Guerrilla MDS/MDM The Road To Data Governance

    Date: Thursday 19 December Noon PST / 3 PM EST / 8 PM GMT
    Speakers: Ira Whiteside and Victoria Stasiewicz
    URL: https://attendee.gotowebinar.com/register/336644427020709122

    Ira and Vic's session "Guerrilla MDS" will be a walk-through of a real-world implementation for a master data model (MDM) and metadata mart utilizing SSIS, MDS and POWER BI EXCEL add-ins as well as applying proper data quality techniques. We will walk through in detail the processes necessary for utilizing the complete MDS functionality as follows: creating entities attribute, relating entities the domain based attributes, staging leave table, updated entity content, apply business rules, create subscription view and set up security. Source code for all samples and PowerPoint will be made available. 

  • Fundamentals of SQL Server 2012 Replication

    From Red-Gate web site you can download, for free (plus a trial of SQL Monitor), the eBook Fundamentals of SQL Server 2012 Replication written by Sebastian Meine (@sqlity).

    Data replication is traditionally considered a complex feature and generally we get discouraged easily, already during the preparation of the test environment. Why the implementation of a SQL Server Replication is considered a complex activity? Which problems could you meet? The most common problems that you could encounter are related to the database schema that it has to be thought for replication scenarios and there could be problems related to the replication agents' permissions. Finally, you may encounter problems related to the architecture of the network and the Internet bandwidth especially if you want to implement a web replication or if you have to use an ftp area for data exchange. To do a good job, we need different skills.

    This book cannot miss in your digital library! And obviously you can buy the paperback on Amazon.

    Editorial Review

    Many of my clients need to make data that lives on one server available on another server. There are many reasons for such a requirement. You might want to speed up cross-server queries by providing a local copy of the data. Or you might want to make the data available to resource intensive reporting queries without impacting the OLTP load, maybe even with an intentional delay so you're always reporting against complete days only. Finally, you might be looking to implement high availability. In all these situations, SQL Server Replication is a viable option to look at when planning for the implemen­tation of such a requirement.

    With this book, I want to introduce you into the vast world of SQL Server Replication and show you its most important strength and weaknesses. After working through the exercises, you will be able to make an informed decision whether replication is the right feature to use and which type of replication is the most advantageous in your situation. You will also know when to stay away from replication and use other features such as simple log shipping or the new "Always On" feature set.

    Fundamentals of SQL Server 2012 Replication provides a hands-on introduction to SQL Server replication. The book begins with a short overview that introduces you to the technologies that make up replication. In the following chapters, the book will walk you through setting up different replication scenarios. All hands-on exercises are designed with security best practices in mind. When you're finished working through the exercises, you will be able to implement your own multi-server replication setup while following the principle of least privilege.


    Enjoy the book!

  • Microsoft MVP Award Renewal 2013

    There is a day of the year in which an MVP is "expiring" and in that day he hopes to receive the renewal notification email for this important professional recognition. The MVP Award Program is the way used by Microsoft to say "Thanks for your commitment"... thanks for sharing your technical knowledge with others, thanks for helping others in the worldwide technical communities.

    Today is the expiration day of my MVP Award, but is also the renewal day because I have received the long awaited email "Congratulations 2013 Microsoft MVP!" I begin in this way my fourth year in the MVP Award Program for SQL Server. It is an honor for me to be part of this magic group of people that every day share their technical knowledge with others, with passion!

    In the past, someone asked me "How can I becoming an MVP?" or "What did you do for becoming an MVP?" My answer was: "Learn a technology very well and keep the pace because it will change quickly; help others about using this technology, not for money but only for a Thanks and put passion in all of this!". This is my point of view of the page Becoming an MVP.

    Thanks very much to all of you; I will do my best to bring in a responsible way this great recognition!

    Congrats to new MVPs and to all MVPs renewed:

    Therefore, this year, SQL Saturday in Italy is a certainty! From October to December in Italy there will be three SQL Saturday events!

    The first one: October 8th 2013, Milan

    The second one: November 9th 2013, Verona

    The third: 2013 December 13th, Ancona

    All the CFPs are still open, if there are one or more arguments related to SQL Server, that you take care or that you are interested in, send your session proposals! It could be a great opportunity to visit Italy.

    See you there!

  • SQL Server Backup and Restore

    From Red-Gate web site you can download, for free, the eBook SQL Server Backup and Restore written by Shawn McGehee.

    One of the most important activities under DBA responsibility is to check backups and maintain an efficient recovery plan. In this book, Shawn McGehee explains how to build an efficient recovery plan; because after you have known that your database is in "Suspect Mode" or is corrupt and some data were lost, there is no worst news of that tells you that no valid backups are available for database recovery. It is not enough to take a backup, you must ensure that it is also possible to perform the restore!

    This book cannot miss in your digital library! And obviously you can buy the paperback on Amazon.

    Editorial Review

    The duties and responsibilities of a Database Administrator (DBA) make for a long and dynamically changing list, ranging from offering query tuning advice, to cutting stored procedures, all the way through to system process design and implementation for high availability. A DBA's tasks, from day-to-day, are rarely constant; with one exception: the need to ensure each and every day that any database in their charge can be restored and recovered, in the event of error or disaster. This means that if a database, for whatever reason, gets corrupted, dropped, or otherwise becomes unusable, then it is the DBA's responsibility to restore that database to the state it was in before the problem occurred, or as close as is possible.

    Of course, this doesn't mean that a DBA is required to restore a database each and every day, just that if disaster does strike the DBA must be prepared to deal with it, regardless of when or why it occurs. If a DBA isn't prepared, and significant data is lost, or databases become unavailable to end users for long periods of time, then that DBA probably won't be in their job for too long. This is why a good, and tested, SQL Server backup and restore plan must be on the top of every administrative DBA's list of tasks.

    In this book, you'll discover how to perform each of these backup and restore operations using SQL Server Management Studio (SSMS), basic T-SQL scripts and Red Gate's SQL Backup tool. Capturing backups using SSMS or simple scripts is perfectly fine for one-off backup operations, but any backups that form part of the recovery strategy for any given database must be automated and you'll also want to build in some checks that, for example, alert the responsible DBA immediately if a problem arises. The tool of choice in this book for backup automation is Red Gate's SQL Backup Pro. Building your own automated solution will take a lot of work, but we do offer some advice on possible options, such as PowerShell scripting, T-SQL scripts and SQL Server Agent jobs.

    Enjoy the book!

  • How to install NetFx3 on Windows Server 2012 (required by SQL Server 2012)

    In this post, we will learn how to install the NetFx3 feature (.Net Framework 3.5) on Windows Server 2012 (R2). This feature is required by SQL Server 2012.

    Scenario

    Recently I have had the opportunity to setup a new Windows Server 2012 (R2) virtual machine in which I must install a new SQL Server 2012 instance. SQL Server 2012 Service Pack 1 installation wizard requires NetFx3 Windows feature enabled, if that feature is not enable, the SQL Server 2012 setup wizard will end with the error shown in the following picture.

    Picture 1 – Error while enabling Windows feature: NetFx3

     

    How to install NetFx3 on Windows Server 2012 (R2)

    First, we have to open the Server Manager Tool of Windows Server 2012 (R2) and then we have to click on the Add Roles and Features item in the Manage menu as shown in the following picture.

    Picture 2 – Add Roles and Features item in the Manage menu

     

    If we have not already specified that we want to ignore the preliminary operations, it will show the Before you begin section of the Add Roles and Feature wizard as shown in the following picture.

    Picture 3 – Before you begin section of the Add Roles and Features wizard

     

    Click Next button, the wizard will shows the Installation Type section where we have to select the Role-based or feature-based installation option that it has used to configure this server by adding roles, role services and features. Picture number 4 shows the Installation Type section.

    Picture 4 – Installation Type section of Add Roles and Features wizard

     

    Click Next button, it will show the Server Selection section; in this section we have to select the Server on which to install NetFx3 feature, so click Select a server from the server pool and over the grid, select the server as shown in the following picture.

    Picture 5 – Server Selection section of the Add Roles and Features wizard

     

    Click Next button again, the wizard will shows the Server Roles section as you can see in the following picture.

    Picture 6 – Server Roles section of Add Roles and Feature wizard

     

    No selections are required in this section because we have to add a feature (NetFx3 is a Windows feature) and not a Server Roles. Click Next button to go to the Features section that shows all the Windows features that you can install on the selected server. As you can see, .Net Framework 3.5 Features has not installed yet; click in the related check box as shown the following picture.

    Picture 7 – Features section of the Add Roles and Feature wizard

     

    Click Next button, the wizard will shows the Confirmation section.

    Picture 8 – Confirmation section of the Add Roles and Features wizard

     

    As you can see, at the top of the window shown in the picture number 8 there is a warning message. It informs you that for one or more installation selections are missing source files on the destination server, so we have to specify an alternative source path. Click the Specify an alternative source patch link, the wizard will shows the window in the following picture.

    Picture 9 – Specify an alternative source path for NetFx3 source files

     

    The required source files for the .Net Framework 3.5 are in Windows Server 2012 (R2) DVD (or in the related ISO file); in this virtual machine, the DVD device is associated to the letter "F". Therefore, you can specify this alternative path "F:\Sources\SxS". Click OK button to return in the previous window (picture 8), so click Install button to start the installation process. The Results section will show the installation status, at the end the status will be Completed successfully as shown in the following picture.

    Picture 10 – Result section of Add Roles and Feature wizard

     

    The NetFx3 (.Net Framework 3.5) feature has been installed in your system. Now we can retry to install SQL Server 2012 Service Pack 1, the error shown in the picture 1 has been fixed.

    Summary

    By default, on Windows Server 2012 (R2) the NetFx3 (.Net Framework 3.5) feature is not installed because is already installed the .Net Framework 4.5; however some applications may require the NetFx3 feature and in this post we have learned how to install it.

    This test has been done in a VMware virtual machine. Thanks to VMware Gurus Program because it donated to MVPs a license of VMware products.
