Microsoft 70-461 Exam Topics:
| Objective | Details |
|---|---|
| Create database objects (20–25%) |
1. Create and alter tables using T-SQL syntax (simple statements)
- Create tables without using the built in tools; ALTER; DROP; ALTER COLUMN; CREATE
2. Create and alter views (simple statements)
- Create indexed views; create views without using the built in tools; CREATE, ALTER, DROP
3. Design views
- Ensure code non regression by keeping consistent signature for procedure, views and function (interfaces); security implications
4. Create and modify constraints (simple statements)
- Create constraints on tables; define constraints; unique constraints; default constraints; primary and foreign key constraints
5. 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%) |
1. 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
2. Implement sub-queries
- Identify problematic elements in query plans; pivot and unpivot; apply operator; cte statement; with statement
3. 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
4. Implement aggregate queries
- New analytic functions; grouping sets; spatial aggregates; apply ranking functions
5. 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%) |
1. 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
2. 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
3. Combine datasets
- Difference between UNION and UNION all; case versus isnull versus coalesce; modify data by using MERGE statements
4. 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%) |
1. 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
2. Manage transactions
- Mark a transaction; understand begin tran, commit, and rollback; implicit vs explicit transactions; isolation levels; scope and type of locks; trancount
3. Evaluate the use of row-based operations vs. set-based operations
- When to use cursors; impact of scalar UDFs; combine multiple DML operations
4. Implement error handling
- Implement try/catch/throw; use set based rather than row based logic; transaction management
