About
The SQL Research skill provides a rigorous, standardized framework for investigating how SQL functions and commands behave across various database dialects such as PostgreSQL, SQL Server, and BigQuery. Designed primarily for developers working on SQL-generating tools like dbplyr, it enforces a workflow that prioritizes official documentation, identifies edge cases like NULL handling and type coercion, and documents findings in a structured format. This ensures that any subsequent SQL implementation is accurate, version-compatible, and robust across different database backends.
