Question

i am trying trying to get a query from oracle table called “sys.all_objects”
into a string variable, so then i can give it to “dbms_obfuscation_toolkit.DESEncrypt” as input, after than encrypted string will go in to “utl_file” so i can write it into a txt file.

Here’s the problem, when i try to query with this code;

DECLARE
TYPE name_array is array(50) OF varchar2(100);
var_input  name_array; 

BEGIN
SELECT owner
  INTO var_input
  FROM sys.all_objects;

  FOR i IN var_input.FIRST .. var_input.LAST
    LOOP
        dbms_output.put_line(var_input(i));
    END LOOP;
END;

and the error is;

ORA-06550: line 7, column 12:
PLS-00642: local collection types not allowed in SQL statements

any idea about geting through this issue ?

for the ones who want to see the full code ;

CREATE OR REPLACE DIRECTORY data AS 'd:\folder';
GRANT read, write ON DIRECTORY data TO PUBLIC;

DECLARE
var_input  varchar2(64) := 'Rndminpt';
var_key    varchar2(16) := 'Anahtar1'; 
var_enc    varchar2(1024);
var_dec    varchar2(1024);
var_file   utl_file.file_type;

BEGIN

-- (query part)

    dbms_obfuscation_toolkit.DESEncrypt(
        input_string     =>  var_input,
        key_string       =>  var_key,
        encrypted_string =>  var_enc);
    dbms_output.put_line('Encrypted...');

var_file := utl_file.fopen('DATA','textfile.txt','W');            
    utl_file.put_line(var_file,var_enc);
    utl_file.fclose(var_file);        
dbms_output.put_line('Writen in to text... ');      
END;

Try to use cursors and BULK COLLECT instead:
http://www.dba-oracle.com/t_oracle_bulk_collect.htm

should look something like this:

DECLARE
TYPE name_array is array(50) OF varchar2(100);
var_input  name_array; 


cursor c1 is
SELECT owner
  FROM sys.all_objects;

BEGIN
    open c1;
    fetch c1 bulk collect into var_input;
    close c1;

  FOR i IN var_input.FIRST .. var_input.LAST
    LOOP
        dbms_output.put_line(var_input(i));
    END LOOP;
END;
