Introduction to SQL

Build practical skills for organizing and querying relational data with SQL and SQLite. The course introduces database tables, keys and relationships before working through table creation, record changes, filtering, missing values, aggregations and joins. Exercises also cover dates, categories, subqueries and common table expressions; time permitting, participants explore window functions and SQL within reproducible R workflows. No previous SQL or R knowledge is required, and participants receive datasets, setup instructions, code and exercise solutions.
