  },
  driver: 'msnodesqlv8',

async function connectToDatabase() {
  try {
    console.log('Attempting to connect to SQL Server...');
    const pool = await sql.connect(config);
    console.log('Connected to SQL Server');
    return pool;
  } catch (error) {
    console.error('Database connection failed:', error.message);
    throw error;
  }
}
connectToDatabase()

export { connectToDatabase };

app.get('/model_size_shift_counts1', async (req, res) => {
  try {
    const pool = await connectToDatabase();
    const request = pool.request();
    
    
    const result = await request.execute(`GetModelSizeShiftCountsBetweenDates1`);

    
    res.json(result.recordset);

    await pool.close();

  } catch (err) {
    console.error(err);
    res.status(500).send('Internal Server Error');
