python将oracle数据库保存到excel

上代码：

import pandas  as pd
import SqlHelper.ORACLE as ORA

if __name__ == '__main__': 
    #连接数据库
    ms = ORA.ORACLE(host="localhost:1521",db="orcl",user="example",pwd="example")

    ########################################################## 方式一：先读取为二维list，再转dataframe，最后保存为Excel
    reslist = ms.ExecQuery("select * from version ")
    # list转dataframe
    df1 = pd.DataFrame(reslist, columns=['ID', 'VERSION', 'MESSAGE'])
    df1.to_excel("E:\\MyPrj\\Python\\Files\\Excel1.xlsx", index=False)

    ########################################################## 方式二：直接读取为dataframe，然后保存为Excel
    df2 = ms.ExecQueryToDataFrame("select * from version ")
    df2.to_excel("E:\\MyPrj\\Python\\Files\\Excel2.xlsx", index=False)
