Introduction:

This five-day instructor-led course is intended for IT professionals who wish to use the Transact-SQL language to query and configure Microsoft SQL Server. Students are typically database developers and database administrators, but might also be Business Intelligence developers, report creators, or application developers. In this course, students learn how to query single tables, join data from multiple tables, filter and sort data, modify data, use procedures and functions, and implement error handling.

Objectives:

Create single table SELECT queries
Create multiple table SELECT queries
Filter and sort data
Insert, update, and delete data
Query data using built-in functions
Create queries that aggregate data
Create subqueries
Create queries that use table expressions
Use UNION, INTERSECT, and EXCEPT on multiple sets of data
Implement window functions in queries
Use PIVOT and GROUPING SETS in queries
Use stored procedures in queries
Add error handling to queries
Use transactions in queries
