Solr’s JDBC driver supports Python and Jython.
Python
Python supports accessing JDBC using the JayDeBeApi library. The CLASSPATH variable must be configured to contain the solr-solrj jar and the supporting solrj-lib jars.
JayDeBeApi
run.sh
#!/usr/bin/env bash
# Java must already be installed
pip install JayDeBeApi
export CLASSPATH="$(echo $(ls /opt/solr/dist/solr-solrj* /opt/solr/dist/solrj-lib/*) | tr ' ' ':')"
python solr_jaydebeapi.pysolr_jaydebeapi.py
#!/usr/bin/env python
# https://pypi.python.org/pypi/JayDeBeApi/

jdbc_url = "jdbc:solr://localhost:9983?collection=test"
driverName = "org.apache.solr.client.solrj.io.sql.DriverImpl"
statement = "select fielda, fieldb, fieldc, fieldd_s, fielde_i from test limit 10"
conn = jaydebeapi.connect(driverName, jdbc_url)
curs = conn.cursor()
curs.execute(statement)
print(curs.fetchall())
conn.close()
sys.exit(0)Jython
Jython supports accessing JDBC natively with Java interfaces or with the zxJDBC library. The CLASSPATH variable must be configured to contain the solr-solrj jar and the supporting solrj-lib jars.

#!/usr/bin/env bash
# Java and Jython must already be installed
