Why take this course?
The 70-761: Querying Knowledge with Transact-SQL course is designed to offer you the important expertise wanted to put in writing and handle SQL queries utilizing Transact-SQL (T-SQL) for Microsoft SQL Server. This course covers a complete vary of subjects, enabling you to successfully retrieve, manipulate, and analyze knowledge from SQL Server databases.
Key areas coated on this course embrace:
- Querying Knowledge: Study to put in writing and execute SELECT statements to retrieve knowledge from single and a number of tables. Perceive tips on how to use varied kinds of joins (INNER, LEFT, RIGHT, FULL) and implement subqueries for superior knowledge extraction.
- Filtering and Sorting Knowledge: Apply filters utilizing the WHERE clause and perceive operators like BETWEEN, IN, LIKE, and wildcards. Use the ORDER BY clause to kind knowledge and carry out customized and multi-level sorting.
- Utilizing Features: Make the most of built-in capabilities for performing calculations, aggregating knowledge, and manipulating strings and dates. Discover scalar capabilities, mixture capabilities, and window capabilities to boost your queries.
- Grouping Knowledge: Implement GROUP BY to mixture knowledge into abstract rows and apply mixture capabilities similar to COUNT, SUM, AVG, MIN, and MAX. Use HAVING to filter aggregated outcomes and handle advanced grouping situations.
- Modifying Knowledge: Write INSERT, UPDATE, and DELETE statements to switch knowledge inside tables. Study in regards to the implications of those operations on knowledge integrity and concurrency.
- Creating and Managing Views: Create and handle views to simplify advanced queries and enhance knowledge entry. Perceive how views can be utilized for knowledge abstraction and safety.
- Managing Transactions: Implement transaction administration utilizing BEGIN TRANSACTION, COMMIT, and ROLLBACK to make sure knowledge integrity. Study isolation ranges and concurrency management to handle concurrent knowledge entry.
- Optimizing Queries: Analyze and optimize question efficiency utilizing methods similar to indexing, question plans, and efficiency tuning to make sure environment friendly knowledge retrieval.
This course is right for database professionals, builders, and analysts who have to grasp querying methods and improve their SQL Server expertise. By the top of the course, you’ll have a stable understanding of T-SQL and be outfitted to deal with advanced querying duties successfully.
