- Joining multiple tables in a single query
- Common errors when joining data
Advanced Queries
- Subqueries
- CTEs – Common Table Expressions
- CASE WHEN – conditions and categorizations
- Creating helper views
Practical Applications for Analysts
- Identifying missing data and duplicates
- Creating monthly and annual summaries
- Preparing data for export to Excel / Power Query
