Question

May be stupid topic, but…
I have a select contents a function and would like to compile it as stored procedure:

CREATE OR REPLACE PROCEDURE PDATA.FILE_PARALLEL_DUMP
IS
BEGIN

SELECT * FROM TABLE
            (parallel_dump
                (
                CURSOR(
                SELECT 
                to_clob(B1)||to_clob(B2)||to_clob(B3)||to_clob(B4) AS cvs  
FROM 
(select 
(A1...A839) as B4 from 
  PDATA.FILE_TAB) s),
                'PR',
                'TEST_FOLDER'
                )
            ) nt;


END EXT_FILE_PARALLEL_DUMP;
/

But during compilation I am reciving a mistake: PLS-00428: an INTO clause is expected in this SELECT statement.

I know than the structure of select in the stored procedure should be like "select A1, A2 into p_a1, a_A2 from...", but in case below (with using function) i have no idea how to write a correct code. May you help me?
Thank you.

In PL/SQL, the result of a SELECT needs to go somewhere. Either your create a loop:

FOR r IN (SELECT ... your query ) LOOP
   -- do something with the row r
END LOOP;

Or you use use a memory table:

SELECT * INTO mem_tab_instance FROM ....

Or then you need to approach your task in a different way.

Do you have prior experience with another database system such as SQL Server? In this aspect, these systems are very different.
