Here's an example of calling the table function, converting to a SQL dataset, assigning it to a cursor variable, and then returning that via the function. This function could then be invoked from a host environment, say a Java program, and the data will be consumed.
Let's start our exploration of pipelined table functions (which I will also refer to as PTFs in this tutorial) with about as simple an example as you can get. Here are explanations for the steps taken in the code section: Create a schema-level nested table type of strings. Implement the pipelined table function.
