Description
The 70-761: Querying Data with Transact-SQL course is designed to provide you with the essential skills needed to write and manage SQL queries using Transact-SQL (T-SQL) for Microsoft SQL Server. This course covers a comprehensive range of topics, enabling you to effectively retrieve, manipulate, and analyze data from SQL Server databases.
Key areas covered in this course include:
- Querying Data: Learn to write and execute SELECT statements to retrieve data from single and multiple tables. Understand how to use various types of joins (INNER, LEFT, RIGHT, FULL) and implement subqueries for advanced data extraction.
- Filtering and Sorting Data: Apply filters using the WHERE clause and understand operators like BETWEEN, IN, LIKE, and wildcards. Use the ORDER BY clause to sort data and perform custom and multi-level sorting.
- Using Functions: Utilize built-in functions for performing calculations, aggregating data, and manipulating strings and dates. Explore scalar functions, aggregate functions, and window functions to enhance your queries.
- Grouping Data: Implement GROUP BY to aggregate data into summary rows and apply aggregate functions such as COUNT, SUM, AVG, MIN, and MAX. Use HAVING to filter aggregated results and manage complex grouping scenarios.
- Modifying Data: Write INSERT, UPDATE, and DELETE statements to modify data within tables. Learn about the implications of these operations on data integrity and concurrency.
- Creating and Managing Views: Create and manage views to simplify complex queries and improve data access. Understand how views can be used for data abstraction and security.
- Managing Transactions: Implement transaction management using BEGIN TRANSACTION, COMMIT, and ROLLBACK to ensure data integrity. Learn about isolation levels and concurrency control to manage concurrent data access.
- Optimizing Queries: Analyze and optimize query performance using techniques such as indexing, query plans, and performance tuning to ensure efficient data retrieval.
This course is ideal for database professionals, developers, and analysts who need to master querying techniques and enhance their SQL Server skills. By the end of the course, you will have a solid understanding of T-SQL and be equipped to handle complex querying tasks effectively.
