Elevate your SQL expertise through this comprehensive advanced-level course that builds on foundational database query skills. Participants will develop advanced capabilities in Microsoft SQL Server, mastering sophisticated techniques for data retrieval, transformation, and manipulation through structured hands-on projects and real-world scenarios.
This course explores advanced SQL methodologies, including conditional query logic through CASE expressions, sophisticated text extraction using string functions, nested query construction for multi-level data retrieval, views-based querying when standard table access is restricted, and custom functions and stored procedures for code modularity and reusability. These capabilities prepare professionals for data analysis roles, data science positions, database administration responsibilities, and any position requiring expert-level SQL database querying and manipulation.
Primary Learning Outcomes:
- Construct subqueries to retrieve data from multiple database levels and integrate results within parent queries for complex analysis
- Leverage views as query sources when standard table permissions are unavailable or when abstraction is preferred
- Implement conditional logic within queries using CASE statements for dynamic, context-aware data processing
- Design user-defined functions and invoke stored procedures to create reusable, maintainable SQL code blocks
- Master string functions for extracting, manipulating, and formatting text data from database fields
Detailed Course Curriculum:
- Advanced Query Methodology and Techniques
- Subquery construction and nested query execution patterns
- Aggregate functions with window-based calculations for advanced analytics
- Conditional query logic using CASE statements and nested conditions
- Text and string manipulation functions for data extraction and transformation
- Self-join patterns for within-table comparisons and hierarchical data analysis
- Views, User-Defined Functions, and Stored Procedures
- View creation and query execution against view objects
- User-defined function creation with parameter passing for dynamic calculation
- Stored procedure development and execution with parameter handling
Required Prerequisites:
- SQL competency equivalent to Level 2 coursework is essential. Successful prerequisite knowledge includes proficiency with table joins and join types; aggregate functions including SUM, COUNT, AVG, and MAX; GROUP BY and HAVING clauses for result grouping and filtering; and date/time data types and CAST conversion functions.
