    conn = sqlite3.connect(':memory:')
    pd.read_csv(StringIO(clearing_batches_csv)).to_sql('clearing_batches', conn, index=False, if_exists='replace')
    result = pd.read_sql_query("SELECT status, COUNT(*) as count, SUM(total_amount) as total_amount FROM clearing_batches GROUP BY status ORDER BY count DESC", conn)
    print(result.to_string(index=False))
    conn.close()

示例

输入
