Course Details

Querying Data with Transact-SQL

Course Code: 20761

Duration: 5 days

Prerequisite:  

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

Course Description:

This 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.

Course Objectives:

After completing this course, students will be able to: 

  • Describe key capabilities and components of SQL Server. •
  • 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.

Intended Audience:

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.
