Teradata PT can be called from within an external stored procedure (XSP). An XSP is a code module, written in C or C++, which resides on the Teradata Database and is executed using the SQL CALL statement. Using Teradata PT in an XSP provides a potential performance improvement by minimizing data transfer between the client and the database server.
Calling the Teradata PT from within an XSP is only supported when using a 12.0 or later version of the Teradata Database. Using the Teradata PT in a user-defined function (UDF) is not currently supported.
