This section provides guidelines on how to implement the body of a table function that the SELECT statement invokes with constant expression input arguments.

For example, the following statement invokes table_function_1 with a constant argument:

SELECT *
FROM TABLE (table_function_1('STRING_CONSTANT'))
AS table_1;
Although this section discusses how to implement a table function that only handles constant expression input arguments, you can design a table function that can handle constant and variable input arguments. For details on how to implement a variable mode table function, see Variable Mode Table Function Body.
