With our `
SQL Querying: Fundamentals ![]()
course you learned the basics of SQL querying.
_
During this SQL Querying Advanced class you will build on that foundation, learning advanced querying techniques such as writing nested queries and using views to simplify repetitive querying tasks. You will 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.
In This Course You will:
• Construct advanced queries and apply them to data.
• Use nested queries to generate query output.
• Manipulate table data by inserting, modifying, and deleting data.
• Manipulate the structure of tables.
• Work with views to present data.
• Index data to improve querying efficiency.
• Manage database transactions.
