SQL Querying: Advanced
In the course SQL Querying: Fundamentals, you learned the basics of SQL querying. Now that you have a foundation in how to query databases, you will learn in this course how to identify and use advanced querying techniques. In addition, you might find that you need to perform tasks such as modifying the structure of a table; inserting, updating, or deleting data; and indexing tables to optimize query performance. In this course, you will learn how to complete these tasks and more.
In today’s competitive environment, information is one of the most important factors in determining the success of an organization. If you are able to manage and retrieve information efficiently, you can streamline the organization’s processes and give it a competitive edge. As the organization grows, you will need to handle large amounts of data. Under such circumstances, you might need to query multiple tables simultaneously and with increasing frequency. You must step up the speed of generating query output to cope with the increasing demands of data storage, management, and retrieval.
This course is the second part of a two-course series that covers the skills needed to gain a foundational understanding of SQL.
– SQL Querying: Fundamentals
– SQL Querying: Advanced (this course)
Completion of this course will earn 0.575 CEUs.
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.
– Use subqueries to generate query output.
– Manipulate table data by inserting and updating records in a table and deleting records from a table.
– Manipulate the 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, SQL skills, and be familiar with concepts related to database structure and terminology.
