# -------------------提取查询结果有四种方式-----------------------#
    # 1.先调用fetch_row(stmt),有结果返回true否则返回false,再调用ibm_db.result(stmt, col_idx)提取结果
    # ibm_db.fetch_row(stmt)
    # result = ibm_db.result(stmt, 0)

    # 2.调用fetch_both(stmt)提取一行,返回的结果是一个字典,取值可以用列名或索引 result["MOBILE"]或 result[0]
    # result = ibm_db.fetch_both(stmt)

    # 3.调用fetch_assoc(stmt)提取一行,返回的是一个字典,取值只能用列明 result["MOBILE"]
    # result = ibm_db.fetch_assoc(stmt)

    # 4.调用fetch_tuple(stmt)提取一行,返回的是一个元组,取值只能用索引 result[0]
    # result = ibm_db.fetch_tuple(stmt)

    # 注: ibm_db没办法一次提取多行,提取多行数据,需要循环提取
