Curso 20761: Querying Data with Transact-SQL

Descripción

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

 

Objetivos

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.
