Microsoft 70-461 Exam Topics:

Objective Details

Create database objects (20–25%)

Create and alter tables using T-SQL syntax (simple statements) - Create tables without using the built in tools; ALTER; DROP; ALTER COLUMN; CREATE
Create and alter views (simple statements) - Create indexed views; create views without using the built in tools; CREATE, ALTER, DROP
Design views - Ensure code non regression by keeping consistent signature for procedure, views and function (interfaces); security implications
Create and modify constraints (simple statements) - Create constraints on tables; define constraints; unique constraints; default constraints; primary and foreign key constraints
Create and alter DML triggers - Inserted and deleted tables; nested triggers; types of triggers; update functions; handle multiple rows in a session; performance implications of triggers

Work with data (25–30%)

Query data by using SELECT statements - Use the ranking function to select top(X) rows for multiple categories in a single query; write and perform queries efficiently using the new (SQL 2005/8->) code items such as synonyms, and joins (except, intersect); implement logic which uses dynamic SQL and system metadata; write efficient, technically complex SQL queries, including all types of joins versus the use of derived tables; determine what code may or may not execute based on the tables provided; given a table with constraints, determine which statement set would load a table; use and understand different data access technologies; case versus isnull versus coalesce
Implement sub-queries - Identify problematic elements in query plans; pivot and unpivot; apply operator; cte statement; with statement
Implement data types - Use appropriate data; understand the uses and limitations of each data type; impact of GUID (newid, newsequentialid) on database performance, when to use what data type for columns
Implement aggregate queries - New analytic functions; grouping sets; spatial aggregates; apply ranking functions
Query and manage XML data - Understand XML datatypes and their schemas and interop w/, limitations and restrictions; implement XML schemas and handling of XML data; XML data: how to handle it in SQL Server and when and when not to use it, including XML namespaces; import and export XML; XML indexing

Modify data (20–25%)

Create and alter stored procedures (simple statements) - Write a stored procedure to meet a given set of requirements; branching logic; create stored procedures and other programmatic objects; techniques for developing stored procedures; different types of storeproc result; create stored procedure for data access layer; program stored procedures, triggers, functions with T-SQL
Modify data by using INSERT, UPDATE, and DELETE statements - Given a set of code with defaults, constraints, and triggers, determine the output of a set of DDL; know which SQL statements are best to solve common requirements; use output statement
Combine datasets - Difference between UNION and UNION all; case versus isnull versus coalesce; modify data by using MERGE statements
Work with functions - Understand deterministic, non-deterministic functions; scalar and table values; apply built-in scalar functions; create and alter user-defined functions (UDFs)

Troubleshoot and optimize (25–30%)

Optimize queries - Understand statistics; read query plans; plan guides; DMVs; hints; statistics IO; dynamic vs. parameterized queries; describe the different join types (HASH, MERGE, LOOP) and describe the scenarios they would be used in
Manage transactions - Mark a transaction; understand begin tran, commit, and rollback; implicit vs explicit transactions; isolation levels; scope and type of locks; trancount
Evaluate the use of row-based operations vs. set-based operations - When to use cursors; impact of scalar UDFs; combine multiple DML operations
Implement error handling - Implement try/catch/throw; use set based rather than row based logic; transaction management

The Microsoft has created this credential to assess the knowledge and understanding of a candidate in the area as above via the certification exam. The Querying Microsoft SQL Server (70-461) Certification exam contains a high value in the market being the brand value of the Microsoft attached with it. It is highly recommended to a candidate to do a thorough study and also get a hand full of the practice to clear Querying Microsoft SQL Server 2012/2014 exam without any hiccups.
