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

After you import the modules, including the CData Python Connector for SAP Cloud for Customer, you can use the 本製品's connect function to create a connection using a valid SAP Cloud for Customer connection string. If you prefer not to use a direct connection, you can use a SQLAlchemy engine.

import petl as etl
import cdata.saphybrisc4c as mod
cnxn = mod.connect("User=user;Password=password;")

Extract, Transform, and Load the SAP Cloud for Customer Data

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

sql = "SELECT	ObjectID, AccountName FROM AccountCollection "
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 SAP Cloud for Customer tables using Petl's appenddb function.

table1 = [['ObjectID','AccountName'],['Jon Doe','John']]
etl.appenddb(table1,cnxn,'AccountCollection')
