This 5-day instructor led course provides students with the technical skills required to write basic Transact-SQL queries for Microsoft SQL Server 2012. This course is the foundation for all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence. This course helps people prepare for exam 70-461.
All the labs for this course can be performed using the provided virtual machines. However, if you have a Microsoft Windows Azure account and the classroom virtual machines connect to the internet you may be able to connect to your Windows Azure server and database from the classroom. Many of the labs in this course are enabled for you to perform the lab while connected to your own Windows Azure database in the cloud. Your instructor should be able to provide a current list of Windows Azure enabled labs. To acquire a trial Windows Azure account click here.

- Filtering Data with a WHERE Clause
- Filtering with the TOP and OFFSET-FETCH Options
- Working with Unknown and Missing Values
Módulo 7 Working with SQL Server 2012 Data Types
This module explains the data types SQL Server uses to store data. It introduces the many types of numeric and special-use data types. It also explains conversions between data types, and the importance of type precedence.
- Introducing SQL Server 2012 Data Types
- Working with Character Data

- Using Conversion Functions
- Using Logical Functions
- Using Functions to Work with NULL
Módulo 9 Grouping and Aggregating Data
This module introduces methods for grouping data within a query, aggregating the grouped data and filtering groups with HAVING.

- Using Aggregate Functions
- Using the GROUP BY Clause
- Filtering Groups with HAVING
Módulo 10 Using Subqueries
This module will introduce the use of subqueries in various parts of a SELECT statement. It will include the use of scalar and multi-result subqueries, and the use of the IN and EXISTS operators.
- Writing Self-Contained Subqueries
- Writing Correlated Subqueries
- Using the EXISTS Predicate with Subqueries
