Use standard Python scripting and the development environment of your choice to access live SFTP data.
Access SFTP data with Python scripts and standard SQL on any machine where Python and Java can be installed. You can use the CData JDBC Driver for SFTP and the JayDeBeApi module to work with remote SFTP data in Python. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular Python language. This article shows how to use the driver to execute SQL queries to SFTP and visualize SFTP data with standard Python.
Use the JayDeBeApi module
JayDeBeApi is a Python library that serves as a JDBC (Java Database Connectivity) bridge, allowing Python programs to interact with Java databases, including CData JDBC Drivers. Use the pip install command to install the module:
pip install JayDeBeApi
Create the JDBC URL
Once you have JayDeBeApi installed, you are ready to work with SFTP data in Python using SQL.
SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.
Set the following connection properties to control the relational view of the file system:
- RemotePath: Set this to the current working directory.
- TableDepth: Set this to control the depth of subfolders to report as views.
- FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the SFTP JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.sftp.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a sample variable assignment, including a typical JDBC connection string:
jdbc_url = "jdbc:sftp:RemoteHost=MyFTPServer;"
Access SFTP data in Python
With the JDBC URL configured, you only need the absolute path to the JDBC driver JAR file, which is in the "lib" folder in the installation directory ("C:\Program Files\CData[product_name] 20XX\lib\cdata.jdbc.sftp.jar" on Windows).
NOTE: If you haven't already, set the JAVA_HOME environment variable to the Java installation directory.
Use code similar to the follow to read and print data from SFTP:
import jaydebeapi
#The JDBC connection string
jdbc_url = "jdbc:sftp:RemoteHost=MyFTPServer;"
username = "****"
password = "****"
#The absolute Path to the JDBC driver JAR file, typically:
jdbc_driver_jar = "C:\Program Files\CData[product_name] 20XX\lib\cdata.jdbc.sftp.jar"
conn = jaydebeapi.connect(
"cdata.jdbc.sftp.SFTPDriver",
jdbc_url,
[username, password],
jdbc_driver_jar,
)
cursor = conn.cursor()
cursor.execute("SELECT * FROM MyDirectory;")
results = cursor.fetchall()
for row in results:
print(row)
cursor.close()
conn.close()
