[jahnvi480]

Work Item / Issue Reference

AB#3806

---

Summary

This pull request enhances the Cursor class in mssql_python/cursor.py to support method chaining by modifying the execute method to return the cursor itself. It also introduces comprehensive test coverage for method chaining in tests/test_004_cursor.py.

Enhancements to the Cursor class:

• Modified the execute method in mssql_python/cursor.py to return the Cursor instance, enabling method chaining. (`[[1]]

Updates to test cases:

• Simplified the test_longwvarchar test by removing unnecessary loops and assertions, improving readability.
• Added new test cases to validate method chaining functionality, including:
  • Chaining execute with fetchone, fetchall, fetchmany, rowcount, and description.
  • Testing multiple sequential operations and parameterized queries.
  • Ensuring chaining works correctly after errors and with statement reuse for performance.

Pull Request Overview

This pull request enhances the Cursor class by adding method chaining support and iteration capabilities. The changes enable developers to chain operations like cursor.execute().fetchone() and iterate directly over cursor results using for row in cursor.execute(sql).

Key changes include:

• Modified the execute method to return the cursor object itself for method chaining
• Added __iter__ and __next__ methods to make the cursor iterable
• Comprehensive test coverage validating chaining operations, iteration, error handling, and compatibility

• The test assumes that rows have attribute access (row.user_id, row.user_name) but the cursor returns list/tuple objects. This will cause an AttributeError. Use index access instead: row[0] for user_id and row[1] for user_name.
