After completing this module, you will be able to:

  • Describe the elements of T-SQL and their role in writing queries
  • Describe the use of sets in SQL Server
  • Describe the use of predicate logic in SQL Server

Module 3: Writing SELECT Queries 

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

Lessons

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

Lab : Writing Basic SELECT Statements 

After completing this module, you will be able to:

  • Write simple SELECT statements.
  • Eliminate duplicates using the DISTINCT clause.
  • Use column and table aliases.
  • Write 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. 

Lessons

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

Lab : Querying Multiple Tables 

After completing this module, you will be able to:

  • Describe how multiple tables may be queried in a SELECT statement using joins.
  • Write queries that use inner joins.
  • Write queries that use outer joins.
  • Write queries that use self-joins and cross 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. 

Lessons

  • Sorting Data
  • Filtering Data with Predicates
  • Filtering with the TOP and OFFSET-FETCH Options
  • Working with Unknown Values

Lab : Sorting and Filtering Data 

After completing this module, you will be able to:

  • Filter data with predicates in the WHERE clause.
  • Sort data using ORDER BY.
  • Filter data in the SELECT clause with TOP.
  • Filter data with OFFSET and FETCH.

Module 6: Working with SQL Server 2016 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. 

Lessons

  • Introducing SQL Server 2016 Data Types
  • Working with Character Data
  • Working with Date and Time Data

Lab : Working with SQL Server 2016 Data Types 

After completing this module, you will be able to:

  • Describe numeric data types, type precedence and type conversions.
  • Write queries using character data types.
  • Write queries using date and time data types.

Module 7: Using DML to Modify Data 

This module describes the use of Transact-SQL Data Manipulation Language to perform inserts, updates, and deletes to your data. 

Lessons

  • Inserting Data
  • Modifying and Deleting Data

Lab : Using DML to Modify Data 

After completing this module, you will be able to:

  • Insert new data into your tables.
  • Update and delete existing records in your tables.

Module 8: 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. 

Lessons

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

Lab : Using Built-In Functions 

After completing this module, you will be able to:

  • Write queries with built-in scalar functions.
  • Use conversion functions.
  • Use logical functions.
  • Use functions that work with NULL.

Module 9: 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. 

Lessons

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

Lab : Grouping and Aggregating Data 

After completing this module, you will be able to:

  • Write queries which summarize data using built-in aggregate functions.
  • Use the GROUP BY clause to arrange rows into groups.
  • Use the HAVING clause to filter out groups based on a search condition.

Module 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. 

Lessons

  • Writing Self-Contained Subqueries
  • Writing Correlated Subqueries
  • Using the EXISTS Predicate with Subqueries

Lab : Using Subqueries 

After completing this module, you will be able to:

  • Describe the uses of queries which are nested within other queries.
  • Write self-contained subqueries which return scalar or multi-valued results.
  • Write correlated subqueries which return scalar or multi-valued results.
  • Use the EXISTS predicate to efficiently check for the existence of rows in a subquery.

Module 11: Using Set Operators
