Querying Data with Transact-SQL (20761B)
DescriptionThis course is designed to introduce students to Transact-SQL. It is designed in such a way that the first three days can be taught as a course to students requiring the knowledge for other courses in the SQL Server curriculum. Days 4 & 5 teach the remaining skills required to take exam 70-761.
SyllabusModule 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 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. Module 3: Writing SELECT Queries This module introduces the fundamentals of the SELECT statement, focusing on queries against a single table. Module 4: Querying Multiple Tables This module describes how to write queries that combine data from multiple sources in Microsoft SQL Server 2016. Module 5: Sorting and Filtering Data This module describes how to implement sorting and filtering. Module 6: Working with SQL Server 2016 Data Types This module introduces the data types SQL Server uses to store data. Module 7: Using DML to Modify Data This module describes how to create DML queries, and why you would want to. Module 8: Using Built-In Functions This module introduces some of the many built in functions in SQL Server 2016. Module 9: Grouping and Aggregating Data This module describes how to use aggregate functions. Module 10: Using Subqueries This module describes several types of subquery and how and when to use them. 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. Module 17: Implementing Error Handling This module introduces error handling for T-SQL. Module 18: Implementing Transactions This module describes how to implement transactions.

- 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.

Participants and RequirementsThe 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. Before attending this course, students must have: • Basic knowledge of the Microsoft Windows operating system and its core functionality. • Working knowledge of relational databases.
