About this Course

This condensed course has been created for SQL users, who would like to focus on writing basic Select statements against the SQL server 2012-2014 database over a 3 day period.

For a more in-depth training course that covers writing Transact SQL queries, or if you are working towards certification or have Microsoft software assurance vouchers that you would like to utilise for training then the following 5 day course is recommended. 20461: Querying Microsoft SQL Server 2012-2014.

Please note we supply digital courseware with this course. If a hard copy is preferred an additional cost will apply.

Audience

This course is intended for Database Administrators, Database Developers, and Business Intelligence professionals who are responsible for writing queries

Prerequisites

Before attending this course, students must have:

• Working knowledge of relational databases.
• Basic knowledge of the Microsoft Windows operating system and its core functionality.
• Basic understanding of virtualization technology (Classroom labs utilize virtual machines)

At Course Completion

This course provides students with the technical skills required to write basic Transact-SQL queries for Microsoft SQL Server 2012-2014. This course is the foundation for all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence.

After completing this course, students will be able to:

• Write SELECT queries
• Query multiple tables
• Use built-in functions
• Use subqueries
• Use set operators
• Sort and filter data
• Use window ranking, offset and aggregate functions

Course Outline

Module 1: Introduction to Microsoft SQL Server 2012-2014

This module introduces the SQL Server platform and major tools. It discusses editions, versions, tools used to query, documentation sources, and the logical structure of databases.

• Introducing Microsoft SQL Server 2012-2014
• Getting Started with SQL Server Management Studio

Module 2: Introduction to T-SQL Querying

This module introduces Transact SQL as the primary querying language of SQL Server. It discusses the basic structure of T-SQL queries, the logical flow of a SELECT statement, and introduces concepts such as predicates and set-based operations.

• Introducing T-SQL
• Understanding Sets
• Understanding Predicate Logic
• Understanding the Logical Order of Operations in SELECT statements

Module 3: Writing SELECT Queries

This module introduces the fundamentals of the SELECT statement, focusing on queries against a single table.

• Writing Simple SELECT Statements
• Eliminating Duplicates with DISTINCT
• Using Column and Table Aliases
• Writing Simple CASE Expressions

Module 4: Querying Multiple Tables

This module explains how to write queries which combine data from multiple sources in SQL Server. The module introduces the use of JOINs in T-SQL queries as a mechanism for retrieving data from multiple tables.

• Understanding Joins
• Querying with Inner Joins
• Querying with Outer Joins
• Querying with Cross Joins and Self Joins

Module 5: Sorting and Filtering Data

This module explains how to enhance queries to limit the rows they return, and to control the order in which the rows are displayed. The module also discusses how to resolve missing and unknown results.

• Sorting Data
• Filtering Data with a WHERE Clause
• Filtering with the TOP and OFFSET-FETCH Options
• Working with Unknown and Missing Values

Module 6: Working with SQL Server 2012-2014 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 2012-2014 Data Types
• Working with Character Data
• Working with Date and Time Data

Module 7: Using Built-In Functions

This module introduces the use of functions that are built in to SQL Server Denali, and will discuss some common usages including data type conversion, testing for logical results and nullability.

• Writing Queries with Built-In Functions
• Using Conversion Functions
• Using Logical Functions
• Using Functions to Work with NULL

Module 8: Grouping and Aggregating Data

This module introduces methods for grouping data within a query, aggregating the grouped data and filtering groups with HAVING. The module is designed to help the student grasp why a SELECT clause has restrictions placed upon column naming in the GROUP BY clause as well as which columns may be listed in the SELECT clause.

• Using Aggregate Functions
• Using the GROUP BY Clause
• Filtering Groups with HAVING

Module 9: 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

Module 10: Using Set Operators

This module introduces operations involving multiple sets of data. It will cover the use of the UNION, UNION ALL, APPLY, CROSS APPLY, OUTER APPLY operators as well as the EXCEPT and INTERSECTS operators.

• Writing Queries with the UNION Operator
• Using EXCEPT and INTERSECT
• Using APPLY

Module 11: Using Window Ranking, Offset and Aggregate Functions

This module introduces window functions including ranking, aggregate and offset functions. Much of this functionality is new to SQL Server 2012. It will cover the use of T-SQL functions such as ROW_NUMBER, RANK, DENSE_RANK, NTILE, LAG, LEAD, FIRST_VALUE and LAST_VALUE to perform calculations against a set, or window, of rows.

• Creating Windows with OVER
• Exploring Window Functions

Module 12: Pivoting and Grouping Sets

This module discusses techniques for pivoting data in T-SQL as well to introduce the fundamentals of the GROUPING SETS clause. It will also cover the use of GROUP BY ROLLUP and GROUP BY CUBE syntax in SQL Server 2012-2014.

• Writing Queries with PIVOT and UNPIVOT
• Working with Grouping Sets
