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 Zoho Books. You can then use the 本製品's connect function to create a connection using a valid Zoho Books connection string. A SQLAlchemy engine may also be used instead of a direct connection.
import petl as etl import cdata.zohobooks as mod cnxn = mod.connect("InitiateOAuth=GETANDREFRESH;OrganizationId=YourOrganizationId;AccountsServer=YourAccountServerURL")
Extract, Transform, and Load the Zoho Books Data
Create a SQL query string and store the query results in a DataFrame.
sql = "SELECT InvoiceId, InvoiceNumber FROM INVOICES " 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 Zoho Books tables using Petl's appenddb function.
table1 = [['InvoiceId','InvoiceNumber'],['Jon Doe','John']] etl.appenddb(table1,cnxn,'INVOICES')
