Worked on enhancing the DuckDB ODBC driver by delivering robust numeric type handling in the duckdb/duckdb-odbc repository. Focused on improving DECIMAL and NUMERIC precision and scale reporting, supporting 128-bit integer mappings, and ensuring correct sign behavior for negative decimals. Refactored the numeric types codebase for maintainability and expanded test coverage to validate edge cases, including trailing zeros in fractional parts. Addressed pull request feedback and tightened metadata handling for temporal precision and column details. Leveraged C++, SQL, and CMake to increase compatibility with enterprise BI tools, reduce data ambiguity, and lay the foundation for broader ODBC feature support.

Jun 1, 2025June 2025: Focused on strengthening the DuckDB ODBC driver's numeric handling to deliver accurate, standards-conformant data interchange and improve reliability for data-intensive workloads. Delivered ODBC Numeric Types Conformance and Robustness Improvements for duckdb-odbc, including precise DECIMAL/NUMERIC precision and scale reporting, correct signs for negative decimals, support for 128-bit integer mappings, and a refactor of numeric types code to improve maintainability. Expanded test coverage to validate numeric edge cases and trailing zeros in fractional parts. Addressed PR feedback and ensured robust handling of temporal precision and column metadata. These changes reduce data ambiguity, increase compatibility with enterprise BI tools, and lay groundwork for future feature parity with wider ODBC semantics.
