如何将Amazon Redshift连接到python

问题描述

这是我的python代码，我想将Amazon Redshift数据库连接到Python，但是在主机中显示错误.

This is my python code and I want to connect my Amazon Redshift database to Python, but it is showing error in host.

有人可以告诉我正确的语法吗?我可以正确传递所有参数吗?

Can anyone tell me the correct syntax? Am I passing all the parameters correctly?

con=psycopg2.connect("dbname = pg_table_def, host=redshifttest-icp.cooqucvshoum.us-west-2.redshift.amazonaws.com, port= 5439, user=me, password= secret")

这是错误:

推荐答案

您似乎希望从Python代码运行Amazon Redshift查询.

It appears that you wish to run Amazon Redshift queries from Python code.

您要使用的参数是:

• 数据库名称:这是创建集群时在Database name字段中输入的数据库的名称.
• 用户:创建集群时，您是在Master user name字段中输入的.
• 密码:这是您在创建集群时在Master user password字段中输入的.
• 主机:这是Redshift管理控制台中提供的端点(末尾没有端口):redshifttest-xyz.cooqucvshoum.us-west-2.redshift.amazonaws.com
• 端口: 5439

• dbname: This is the name of the database you entered in the Database name field when the cluster was created.
• user: This is you entered in the Master user name field when the cluster was created.
• password: This is you entered in the Master user password field when the cluster was created.
• host: This is the Endpoint provided in the Redshift management console (without the port at the end): redshifttest-xyz.cooqucvshoum.us-west-2.redshift.amazonaws.com
• port: 5439

例如:

con=psycopg2.connect("dbname=sales host=redshifttest-xyz.cooqucvshoum.us-west-2.redshift.amazonaws.com port=5439 user=master password=secret")
