Multi-statement table-valued function for Oracle

I have a function that returns a table in SQL Server with the following format:

CREATE FUNCTION my_sql_function(@dummy int)
RETURNS @pseudo_temp_table TABLE (sql_server_int int)
AS
BEGIN

INSERT @pseudo_temp_table
    SELECT DISTINCT id FROM MyTable

RETURN
END

Is there a way to create a similar User-Defined Function in Oracle?  Thanks.

You would first need to create (or reuse) a user-defined TYPE:

create type int_tab is table of integer;
/

Then your function becomes:

CREATE FUNCTION my_sql_function
RETURN int_tab
AS
  it int_tab;
BEGIN
  SELECT id
  BULK COLLECT INTO it FROM MyTable;

  RETURN it;
END;
/

This can then be used in SQL like this:

SQL> select * from table( cast(my_sql_function as int_tab))
  2  /

COLUMN_VALUE
------------
           1
           2

I created the type as you stated above.

I also created my function similar to above.  My SQL statment looks like the following:

SELECT id INTO it FROM MyTable;

I recevie the following error when I compile it:

19 Error Text = PL/SQL: ORA-00932: inconsistent datatypes: expected UDT got NUMBER

id in MyTable is a NUMBER but the SQL statement will return many ids.  Any ideas?  Thanks.

Yes, use the BULK COLLECT as I showed it:

SELECT id BULK COLLECT INTO it FROM MyTable;
