Variable Mode Table Function Body | SQL External Routine Programming | Vantage - Variable Mode Table Function Body - Analytics Database - Teradata Vantage

This section provides guidelines on how to implement the body of a table function that the SELECT statement invokes using the columns from a derived table as input arguments.

For example, the following statement invokes table_function_2 using column_1 from the preceding derived table with the t1 correlation name:

SELECT *
FROM ( SELECT column_1
       FROM table_1
       WHERE column_2 > 65 ) AS t1,
     TABLE (table_function_2(t1.column_1)) AS t2 (c1, c2, c3)
WHERE t1.column_3 = t2.c3;
