A diagnostic function that tests whether the pyodbc library can be imported and displays its version information and ODBC compatibility details.

Purpose

This function serves as a health check or diagnostic tool to verify that pyodbc is properly installed and accessible in the Python environment. It's typically used during setup, testing, or troubleshooting database connectivity issues. The function attempts to import pyodbc, retrieves version information, and returns a boolean indicating success or failure.

Source Code

def test_pyodbc_import():
    """Test pyodbc import and basic functionality"""
    print("\n📦 Testing pyodbc import...")
    
    try:
        import pyodbc
        print(f"✅ pyodbc version: {pyodbc.version}")
        
        # Test basic pyodbc functionality
        print(f"✅ pyodbc compiled with ODBC version: {pyodbc.odbcversion}")
        
        return True
        
    except Exception as e:
        print(f"❌ Error importing pyodbc: {e}")
        return False

Return Value

Returns a boolean value: True if pyodbc was successfully imported and basic information was retrieved, False if any exception occurred during the import or information retrieval process. The function also prints diagnostic messages to stdout with emoji indicators for visual feedback.

Dependencies

• pyodbc

Required Imports

import pyodbc

Conditional/Optional Imports

These imports are only needed under specific conditions:

import pyodbc

Usage Example

# Simple usage to test pyodbc availability
result = test_pyodbc_import()

if result:
    print("pyodbc is ready to use")
else:
    print("pyodbc is not available, please install it")

# Example output:
# 📦 Testing pyodbc import...
# ✅ pyodbc version: 4.0.39
# ✅ pyodbc compiled with ODBC version: 03.80

Best Practices

• This function is intended for diagnostic purposes and should be used during setup or troubleshooting phases
• The function prints to stdout, so it's best used in CLI tools or testing scripts rather than production code
• Consider calling this function before attempting database connections to ensure pyodbc is available
• The function catches all exceptions broadly, which is appropriate for a diagnostic tool but may hide specific import issues
• This function does not test actual database connectivity, only the availability of the pyodbc library
