It introduces a new `procedures()` method on the `cursor` object, updates the C++ pybind layer to expose the ODBC `SQLProcedures` API, and includes a comprehensive suite of tests to ensure correct behavior across various scenarios. **New feature: Procedures metadata retrieval** * Added `procedures()` method to the `cursor` class in `mssql_python/cursor.py` to fetch information about stored procedures, handling both temporary (using direct queries) and permanent procedures (using the ODBC API). The method supports filtering by procedure name, catalog, and schema, and returns detailed metadata for each procedure. **ODBC bindings and pybind integration** * Introduced new function pointer type `SQLProceduresFunc` and related extern variable to the ODBC bindings header and implementation files (`mssql_python/pybind/ddbc_bindings.h`, `mssql_python/pybind/ddbc_bindings.cpp`). * Loaded the `SQLProceduresW` function pointer during driver initialization and included it in the required function check. * Implemented a wrapper function `SQLProcedures_wrap` and exposed it to Python as `DDBCSQLProcedures` for cross-platform use. **Testing and validation** * Added a comprehensive set of tests to `tests/test_004_cursor.py` to verify the new `procedures()` functionality, including filtering by name, schema, and catalog, handling of input/output parameters, result set reporting, and correct behavior with non-existent procedures. --------- Co-authored-by: Jahnvi Thakkar <jathakkar@microsoft.com>

Work Item / Issue Reference
Summary
This pull request adds support for retrieving ODBC data type information via a new
getTypeInfomethod on thecursorobject, exposing the underlyingSQLGetTypeInfoAPI. It includes the necessary C++/Python bindings, error handling, and comprehensive test coverage to ensure correct behavior for different data types and usage scenarios.Feature: Data type information retrieval
getTypeInfomethod to thecursorclass inmssql_python/cursor.py, allowing users to retrieve metadata about supported SQL data types via the ODBCSQLGetTypeInfoAPI. The method supports querying all types or a specific type and returns results as a list ofRowobjects with a well-defined column map.Bindings and driver integration
SQLGetTypeInfo(SQLGetTypeInfoFunc) and integrated it into the driver loading and verification process inmssql_python/pybind/ddbc_bindings.handmssql_python/pybind/ddbc_bindings.cpp. This ensures the function pointer is loaded and checked along with other ODBC APIs.SQLGetTypeInfo, exposing it asDDBCSQLGetTypeInfoin the Python module.Testing
tests/test_004_cursor.pyto validate the newgetTypeInfomethod. Tests cover retrieving all types, specific types, result structure, numeric and datetime types, binary types, multiple successive calls, and repeated identical queries for consistency and efficiency.
