Course outline
Module 1: Getting Started with Transact-SQL
In this module you will learn about the basics of the Transact-SQL (T-SQL) language, as well as general properties and terminology of relational databases. This module will also introduce the basic SELECT statement for retrieving data from a table.
Lessons
Introduction to Transact-SQL
Using the SELECT statement
Lab : Get started with SQL Server query tools and writing queries in T-SQL
Module 2: Sorting and Filtering Query Results
In the module you will learn how to control what data is returned, the order in which it is returned. You will use the ORDER BY clause, with and without paging. You will learn about various kinds of filters that can be used in the WHERE clause to control which data rows are returned. You will also learn how to manage the results by removing duplicates with DISTINCT.
Lessons
Sorting query results
Filtering the data
Lab : Sort and filter data returned by SELECT queries
Module 3: Using Joins and Subqueries
In this module, you will explore T-SQL queries which access data from multiple tables with various kinds of JOIN operations and simple subqueries.
Lessons
Using JOIN operations
Using subqueries
Lab : Write queries with JOIN operations
Lab : Write SELECT statements using subqueries
Module 4: Using Built-in Functions
In the module you will explore the use of built-in functions for returning computed or special values in the SELECT list or in the WHERE clause. Functions include math functions, string functions and system functions. There are other types of functions that will be mentioned, but not discussed in detail. You will also learn how to combine rows of data into a single group, providing summary information for the group such as SUM, MIN or MAX.
Lessons
Getting started with scalar functions
Grouping aggregated results
Lab : Built-in functions
Module 5: Modifying Data
In this module, you will learn the T-SQL statements for modifying table data including UPDATE, DELETE and MERGE as well as various options for INSERT including creating a new table with data from an existing table. You will also look at how to have the system automatically supply values for columns as the data is inserted.
Lessons
