How I can debug a stored procedure with a VARRAY parameter?

Question

I have a little trouble to debug a procedure with two VARRAY parameter in TOAD. I have in my DB this VARRAY defined:

CREATE OR REPLACE TYPE BDD_ACTIVOSEPAREP.TORDEN_CAMPO as VARRAY(7) of VARCHAR2(13);

And now I want to debug a procedure that needs this varray as parameter, but when I execute the debug I have this error:

ORA-06550: line 46, column 21: PLS-00316: PL/SQL TABLEs must use a single index
ORA-06550: line 46, column 3: PL/SQL: Statement ignored

ORA-06550: line 47, column 20: PLS-00316: PL/SQL TABLEs must use a single index
ORA-06550: line 47, column 3: PL/SQL: Statement ignored

This is the code that I'm trying to execute:

Thanks for your replies!

PD: The lines 46 and 47 in the ORA ERROR are

  PIVORDEN_CAMPO := PIVORDEN_CAMPO('F_REPOR','PREF','MREF','IFGD','ID_MOVIMIENTO','ID_GRUPO','CASO');
  PIVORDEN_TIPO := PIVORDEN_CAMPO('D','D','D','A','D','D','A');

Answer 1

You have to use the implicit constructor for collections, ie instead of

PIVORDEN_CAMPO := PIVORDEN_CAMPO('F_REPOR','PREF','MREF','IFGD','ID_MOVIMIENTO','ID_GRUPO','CASO');
PIVORDEN_TIPO := PIVORDEN_CAMPO('D','D','D','A','D','D','A');

you should write

PIVORDEN_CAMPO := BDD_ACTIVOSEPAREP.TORDEN_CAMPO('F_REPOR','PREF','MREF','IFGD','ID_MOVIMIENTO','ID_GRUPO','CASO');
PIVORDEN_TIPO := BDD_ACTIVOSEPAREP.TORDEN_CAMPO('D','D','D','A','D','D','A');

because BDD_ACTIVOSEPAREP.TORDEN_CAMPO() is your BDD_ACTIVOSEPAREP.TORDEN_CAMPO -type collections' implicit constructor.
