Passing VARCHAR table as parameter

Question

Here is the situation:
Table_procedure
(procedure name)
Table_parameter
(procedure_name,
parameter_name,
parameter_type,
parameter_value)
I need to get procedure name from Table_procedure (not a problem),
then parameters from Table_parameter (not a problem either).
Then I complie a string in form:
BEGIN procedure_name(parameter_name=>parameter_value,...,parameter_name=>parameter_value); END;
and call EXECUTE IMMEDIATE for that string. It also works.
Now where the problem is:
If parameter type is Pl/SQL VARCHAR2 TABLE declared in procedure something like:
TYPE vctable_type IS TABLE OF VARCHAR2(100) INDEX BY BINARY_INTEGER;
vctable vctable_type;
How can I use previously described logic with this kind of parameter?
Thank you in advance.

Answer 1

Well you could..........
First, I would change the procedure to a package, then I would change the parameter list to a single PL/SQL input type (see example below). Then I would build a PL/SQL table of parameters, and then pass it in.
1)  You select parameter names directly into a PL/SQL table
set echo on
DROP TABLE TEST;
CREATE TABLE TEST ( Str1    VARCHAR2 ( 100 ) );
INSERT INTO TEST VALUES ( 'A' );
INSERT INTO TEST VALUES ( 'b' );
INSERT INTO TEST VALUES ( 'c' );
INSERT INTO TEST VALUES ( 'd' );
INSERT INTO TEST VALUES ( 'e' );
COMMIT;

SQL> set serveroutput on size 1000000
SQL> DECLARE
  2      TYPE t_Varchar2 IS TABLE OF VARCHAR2 ( 2000 )
  3          INDEX BY BINARY_INTEGER;
  4      v_Table  t_Varchar2;
  5      --
  6      --
  7      PROCEDURE Show_Count ( p_Table IN t_Varchar2 )
  8      IS BEGIN
  9          DBMS_OUTPUT.Put_Line ( 'And the count is :' || p_Table.COUNT );
10      END;
11      --
12      --
13  BEGIN
14      SELECT  Str1
15      BULK COLLECT INTO v_Table
16      FROM TEST;
17      --
18      Show_Count ( v_Table );
19  END;
20  /
And the count is :5

2) You could build a comma delimited string and use DBMS_UTILITY.Comma_To_Table to build your PL/SQL table, and then pass it in.Break a leg,
