About this course
This course is designed to introduce students to Transact-SQL. It is designed in such a way that the first 3 days are for students requiring the knowledge for other courses in the SQL Server curriculum. Days 4 & 5 are the remaining skills required to take exam 70-761.

Audience profile
The main purpose of the course is to give students a good understanding of the Transact-SQL language which is used by all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence. As such, the primary target audience for this course is: Database Administrators, Database Developers and BI professionals.

At course completion
After completing this course, students will be able to:

  • Describe key capabilities and components of SQL Server 2016.
  • Describe T-SQL, sets, and predicate logic.
  • Write a single table SELECT statement.
  • Write a multi-table SELECT statement.
  • Write SELECT statements with filtering and sorting.
  • Describe how SQL Server uses data types.
  • Write DML statements.
  • Write queries that use built-in functions.
  • Write queries that aggregate data.
  • Write subqueries.
  • Create and implement views and table-valued functions.
  • Use set operators to combine query results.
  • Write queries that use window ranking, offset, and aggregate functions.
  • Transform data by implementing pivot, unpivot, rollup and cube.
  • Create and implement stored procedures.
  • Add programming constructs such as variables, conditions, and loops to T-SQL code.

Before attending this course, students must have:

  • Basic knowledge of the Microsoft Windows operating system and its core functionality.

Course Outline

  • Module 1: Introduction to Microsoft SQL Server 2016
    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.
  • Module 2: Introduction to T-SQL Querying
    This module introduces the elements of T-SQL and their role in writing queries, describes the use of sets in SQL Server, describes the use of predicate logic in SQL Server, and describes 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. Querying with Inner Joins, Outer Joins, 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 Predicates, Filtering with the TOP and OFFSET-FETCH Options, Working with Unknown Values.
  • 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. Numeric data types, type precedence, type conversions, Character Data, Date and Time Data.
  • 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.
  • Module 8: Using Built-In Functions
    This module introduces the use of functions that are built in to SQL Server, 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 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.
  • 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. 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 structured exception handling, Redirecting errors with TRY/CATCH, Using THROW to pass an error message back to a client.
  • Module 18: Implementing Transactions
    This module describes how to implement transactions. Transactions and the database engines, Controlling transactions with BEGIN, COMMIT, and ROLLBACK, Adding error handling to a CATCH block.
