Summary
SQL Querying: Advanced
In the course SQL Querying: Fundamentals (Second Edition), you learned the basics of SQL querying. In this course, you will build on this foundation, learning advanced querying techniques, such as writing nested queries, using JOINs to combine data from multiple tables, summarizing query results, using advanced filtering, and using views to simplify repetitive querying tasks. You will also learn how to perform common database administration tasks such as duplicating tables, modifying table structures, inserting, updating, or deleting data, and indexing tables to optimize query performance. You will also learn how to work with multiple tasks as a transaction.
This course is the second part of a two-course series that covers the skills needed to gain a foundational understanding of SQL Querying.

Introduction
In this course, you will work with advanced queries to manipulate and index tables. You will also create transactions so that you can choose to save or cancel the data entry process.
You will:
– Use nested queries to generate query output.
– Manipulate table data by inserting and updating records in a table and deleting records from a table.
– Manipulate table structure.
– Create views, manipulate data through views, modify the view structure, and drop views.
– Create indexes on table columns and drop inefficient indexes.
– Mark the beginning of a transaction, roll back a transaction, and commit a transaction.
Students should have basic computer skills and SQL skills, and be familiar with concepts related to database structure and terminology.
