Querying Data with Transact-SQL (MS20761)

Module 1: Introduction to Microsoft SQL Server

This module introduces SQL Server, the versions of SQL Server, including cloud versions, and how to connect to SQL Server using SQL Server Management Studio.

• The Basic Architecture of SQL Server
• SQL Server Editions and Versions
• Getting Started with SQL Server Management Studio

Module 2: Introduction to T-SQL Querying

This module describes 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. Describe the logical order of operations in SELECT statements.

• 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 describes how to write queries that combine data from multiple sources in Microsoft SQL Server 2016.

• 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 describes how to implement sorting and filtering.

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

Module 6: Working with SQL Server 2016 Data Types

This module introduces the data types SQL Server uses to store data.

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

Module 7: Using DML to Modify Data

This module describes how to create DML queries, and why you would want to.

• Inserting Data
• Modifying and Deleting Data

Module 8: Using Built-In Functions

This module introduces some of the many built in functions in SQL Server 2016.

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

Module 9: Grouping and Aggregating Data

This module describes how to use aggregate functions.

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

Module 10: Using Subqueries

This module describes several types of subquery and how and when to use them.

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

Module 11: Using Table Expressions

Previously in this course, you learned about using subqueries as an expression that returned results to an outer calling query. Like subqueries, table expressions are query expressions, but table expressions extend this idea by allowing you to name them and to work with their results as you would work with data in any valid relational table. Microsoft SQL Server 2016 supports four types of table expressions: derived tables, common table expression (CTEs), views, and inline table-valued functions (TVFs). In this module, you will learn to work with these forms of table expressions and learn how to use them to help create a modular approach to writing queries.

• Using Views
• Using Inline Table-Valued Functions
• Using Derived Tables
• Using Common Table Expressions

Module 12: Using Set Operators

This module introduces how to use the set operators UNION, INTERSECT, and EXCEPT to compare rows between two input sets.

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

Module 13: Using Windows Ranking, Offset, and Aggregate Functions

This module describes the benefits to using window functions. Restrict window functions to rows defined in an OVER clause, including partitions and frames. Write queries that use window functions to operate on a window of rows and return ranking, aggregation, and offset comparison results.

• Creating Windows with OVER
• Exploring Window Functions

Module 14: Pivoting and Grouping Sets

This module describes write queries that pivot and unpivot result sets. Write queries that specify multiple groupings with grouping sets

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

Module 15: Executing Stored Procedures

This module describes how to return results by executing stored procedures. Pass parameters to procedures. Create simple stored procedures that encapsulate a SELECT statement. Construct and execute dynamic SQL with EXEC and sp_executesql.

• Querying Data with Stored Procedures
• Passing Parameters to Stored procedures
• Creating Simple Stored Procedures
• Working with Dynamic SQL

Module 16: Programming with T-SQL

This module describes how to enhance your T-SQL code with programming elements.

• T-SQL Programming Elements
• Controlling Program Flow

Module 17: Implementing Error Handling

This module introduces error handling for T-SQL.

• Implementing T-SQL error handling
• Implementing structured exception handling

Module 18: Implementing Transactions

This module describes how to implement transactions.

• Transactions and the database engines
• Controlling transactions
