The text included in the SCRIPT_COMMAND clause runs in its own shell inside a temporary working directory.

For each database named in the SEARCHUIFDBPATH, a link is added to the working directory that has the same name as that database. You must set SEARCHUIFDBPATH in order to access the user-installed files.

To access the Python interpreter with the SCRIPT table operator, you can use the Teradata In-nodes Python interpreter that is provided through the teradata-python rpm on the Advanced SQL Engine nodes.

To access files with the SCRIPT table operator, add a relative path using './', the database name, and '/' the file name.

The following is an example of SCRIPT accessing the 'mapper.py' file in the database called 'mydatabase':

SELECT * FROM SCRIPT
( ON source
SCRIPT_COMMAND('/opt/teradata/languages/Python/bin/python3 ./mydatabase/mapper.py')
);
