CData Python Connector for Amazon Marketplace

Build 20.0.7745

Petl から

The 本製品 can be used to create ETL applications and pipelines for CSV data in Python using Petl.

Install Required Modules

Install the Petl modules using the pip utility.

pip install petl

Connecting

Import the modules, including the CData Python Connector for Amazon Marketplace. You can then use the 本製品's connect function to create a connection using a valid Amazon Marketplace connection string. A SQLAlchemy engine may also be used instead of a direct connection.

import petl as etl
import cdata.amazonmarketplace as mod
cnxn = mod.connect("MWSAuthToken=myMWSAuthToken;SellerId=mySellerId;Marketplace=United States;")

Extract, Transform, and Load the Amazon Marketplace Data

Create a SQL query string and store the query results in a DataFrame.

sql = "SELECT	Id, Column1 FROM SampleTable_1 "
table1 = etl.fromdb(cnxn,sql)

Loading Data

With the query results stored in a DataFrame, you can load your data into any supported Petl destination. The following example loads the data into a CSV file.

etl.tocsv(table1,'output.csv')

Modifying Data

Insert new rows into Amazon Marketplace tables using Petl's appenddb function.

table1 = [['Id','Column1'],['Jon Doe','John']]
etl.appenddb(table1,cnxn,'SampleTable_1')
