20761 Querying Data with Transact SQL

Transcription

1 Course Overview The main purpose of this 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. Who Should Attend This course is intended for Database Administrators, Database Developers, and Business Intelligence professionals. The course will very likely be well attended by SQL power users who aren t necessarily database-focused; namely, report writers, business analysts and client application developers. Course Objectives After completing this course, students will be able to: - Describe the basic architecture and concepts of Microsoft SQL Server Understand the similarities and differences between Transact-SQL and other computer languages. - Write SELECT queries - Query multiple tables - Sort and filter data - Describe the use of data types in SQL Server - Modify data using Transact-SQL - Use builtin functions - Group and aggregate data - Use subqueries - Use table expressions - Use set operators - Use window ranking, offset and aggregate functions - Implement pivoting and grouping sets - Execute stored procedures - Program with T-SQL - Implement error handling Implement transactions Upcoming Dates This is a 5-day class Date Time Where 08/06/ :00AM - 7:00PM Online LIVE 08/13/2018 9:00AM - 5:00PM Online LIVE 08/20/2018 9:00AM - 5:00PM Online LIVE 09/10/2018 9:00AM - 5:00PM Online LIVE 09/17/2018 9:00AM - 5:00PM Online LIVE 09/24/2018 9:00AM - 5:00PM Online LIVE 10/08/ :00AM - 7:00PM Online LIVE 10/15/2018 9:00AM - 5:00PM Online LIVE View All Course Dates & Register Today Course Outline Page 1
