【Python連接數據庫】Python連接Teradata數據庫-TD SQL Driver 方式（teradatasql包）

1.Python安裝

詳見文檔：Python連接Teradata數據庫-ODBC方式

 2.使用teradatasql連接TD數據庫

Teradata SQL驅動(Python)下載地址：teradatasql-16.20.0.42-py3-none-any.whl

（1）使用pip安裝或升級（macOS or Linux系統）

pip install teradatasql-16.20.0.42-py3-none-any.whl   #安裝
pip install --no-cache-dir -U teradatasql  #升級

安裝teradatasql時，出現錯誤Could not find a version that satisfies the requirement pycryptodome.可參考如下文檔解決：安裝teradatasql提示找不到pycryptodome模塊錯誤

（2）使用pip安裝或升級（Windows系統）

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

（3）驗證安裝成功

安裝完畢后，在Python安裝目錄/usr/local/python3/下，新增teradatasql文件夾（測試py文件）。在第三方包目錄/usr/local/python3/lib/python3.6/site-packages 下新增teradatasql文件夾即為成功。

（4）測試腳本

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

# 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 () ]

執行結果如下：
