GitHub Issue: #253

---

Summary

This pull request removes the _select_best_sample_value static method and updates how sample values are selected for type inference in the executemany method. Instead of using the old method, the code now relies on _compute_column_type to determine sample values and type information.

Refactoring and Type Inference Updates:

• Removed the _select_best_sample_value static method from cursor.py, consolidating the logic for type inference.
• Updated the executemany method to use _compute_column_type for determining sample values, minimum, and maximum values for each column, improving clarity and maintainability.

Pull Request Overview

This pull request addresses a type inference bug by removing the _select_best_sample_value static method and consolidating type inference logic into the existing _compute_column_type method.

• Removes redundant _select_best_sample_value method that was duplicating type inference logic
• Updates executemany method to use _compute_column_type for consistent sample value selection
• Simplifies the codebase by eliminating duplicate logic for type inference
