PrerequisiteThe file must be registered with a SQL identifier on ML Engine. In the following steps, sql_identifier is the name with which the file
file_name.txt is registered with Advanced SQL Engine.
An authorized user can install a customized version of a preinstalled model file or input file (a text file) on ML Engine in the default schema, public schema, or both. In the default schema, only the current user can access the file.
- Copy your file to /etc/opt/teradata/tdconfig/Teradata/tdbs_udf/usr on Teradata MPP-1 node.
-
Install the file in the default schema:
CALL SYSUIF.INSTALL_FILE ('sql_identifier', 'file_name.txt', 'sb!file_name.txt'); CALL PM.INSTALL_AFILE ('sql_identifier');
For example:
CALL SYSUIF.INSTALL_FILE ('default_sentiment_lexicon', 'default_sentiment_lexicon.txt', 'sb!default_sentiment_lexicon.txt'); CALL PM.INSTALL_AFILE ('default_sentiment_lexicon');
-
Install the file in the public schema:
CALL SYSUIF.INSTALL_FILE ('sql_identifier', 'file_name.txt', 'sb!file_name.txt'); CALL PM.INSTALL_AFILE_TO_PUBLIC ('sql_identifier');
For example:
CALL SYSUIF.INSTALL_FILE ('default_sentiment_lexicon', 'default_sentiment_lexicon.txt', 'sb!default_sentiment_lexicon.txt'); CALL PM.INSTALL_AFILE_TO_PUBLIC ('default_sentiment_lexicon');
