    Default 70-461: Study Notes/Information

    Hey guys,

    Currently studying for the 70-461 exam which I am due to sit end of the month. I've seen a few people asking about this exam so I thought I'd make a "Study" guide on it hoping this would be the first stop for people looking into taking it.

    Querying SQL 2012

    Skills Being MeasuredThis exam measures your ability to accomplish the technical tasks listed below.The percentages indicate the relative weight of each major topic area on the exam.The higher the percentage, the more questions you are likely to see on that content area on the exam.

    The information after “This objective may include but is not limited to” is intended to further define or scope the objective by describing the types of skills and topics that may be tested for the objective. However, it is not an exhaustive list of skills and topics that could be included on the exam for a given skill area. You may be tested on other skills and topics related to the objective that are not explicitly listed here.

    • Combine datasets.
      • May include but not limited to: difference between UNION and UNION all; case versus isnull versus coalesce; modify data by using MERGE statements
    • Work with functions.
      • May include but not limited to: understand deterministic, non-deterministic functions; scalar and table values; apply built-in scalar functions; create and alter user-defined functions (UDFs)

    Passing 70-461 Exam
    Use this blog now and then to brush up on some points I didn't really understand while reading my book.

    Sample 70-461 Exam Questions (not dumps)
    Quote from their site:
    "Brain dumps
    We take the Microsoft certification platform very serious. As a result, we do not endorse braindumps or braindump type material. You’ll get better rewards from learning the material yourself and becoming a great technical expert. Remember, you shouldn’t download exam dumps, or real exam questions because you’ll end up being a cheat"

    Katie and Emil 70-461 blog
    They list the exam out in parts have articles on each section. They also have a YOUTUBE account.

    WiseOwlTutorials
    A great place to visit if you want to be walked through some querying. He explains it clearly and tells you reasons to behind the query.

    Books

    1. Fundamentals
    2. Teach yourself SQL
    3. 70-461 Microsoft Book

    CBT NUGGETS
    You can get 24 hour access for like Ł15 worth it to cram a day before.

    As well as all this you also have MSDN blogs to go through. These are amazing and will literally write out the code for you, then you can work out how and why it's doing what it does.

    On to of this I will be adding my notes as I go by either as a word doc or by posts.

    Hello knowhero:
    Thanks for sharing your study guide with us. I was just about to post a thread to ask what are the resources used by people who plan to study on their own ans pass the 70-461 exam.

    There are 2 books written by Itzik Ben-Gan:
    Microsoft SQL Server 2012 T-SQL Fundamentals
    Querying Microsoft SQL Server 2012
    Microsoft MSDN for SQL Syntax
