【Python连接数据库】Python连接Teradata数据库-TD SQL Driver 方式（teradatasql包）

1.Python安装

详见文档：Python连接Teradata数据库-ODBC方式

 2.使用teradatasql连接TD数据库

Teradata SQL驱动(Python)下载地址：teradatasql-16.20.0.42-py3-none-any.whl

（1）使用pip安装或升级（macOS or Linux系统）

pip install teradatasql-16.20.0.42-py3-none-any.whl   #安装
pip install --no-cache-dir -U teradatasql  #升级

安装teradatasql时，出现错误Could not find a version that satisfies the requirement pycryptodome.可参考如下文档解决：安装teradatasql提示找不到pycryptodome模块错误

（2）使用pip安装或升级（Windows系统）

py -3 -m pip install teradatasql-16.20.0.42-py3-none-any.whl #安装 
py -3 -m pip install --no-cache-dir -U teradatasql #升级

（3）验证安装成功

安装完毕后，在Python安装目录/usr/local/python3/下，新增teradatasql文件夹（测试py文件）。在第三方包目录/usr/local/python3/lib/python3.6/site-packages 下新增teradatasql文件夹即为成功。

（4）测试脚本

/usr/local/python3/teradatasql/samples/BatchInsert.py

# Copyright 2018 by Teradata Corporation. All rights reserved.

# This sample program demonstrates how to insert a batch of rows.

import teradatasql

with teradatasql.connect ('{"host":"192.168.253.131","user":"dbc","password":"dbc"}') as con:
    with con.cursor () as cur:
        cur.execute ("create volatile table voltab (c1 integer, c2 varchar(100)) on commit preserve rows")

        cur.execute ("insert into voltab (?, ?)", [
            [1, "abc"],
            [2, "def"],
            [3, "ghi"]])

        cur.execute ("select * from voltab order by 1")
        [ print (row) for row in cur.fetchall () ]

执行结果如下：
