To connect a datablock to a query - stored procedure: problem

Question

I have the following table...
CREATE TABLE I_TIPOLOGIA (
CODICE NUMBER(6),
DESCRIZIONE VARCHAR2(100),
CONSTRAINT I_TIPOLOGIA_PK PRIMARY KEY (CODICE) );
and the following package to connect a datablock to
previous table with a stored procedure...
CREATE or REPLACE PACKAGE DATABANKER_TIPOLOGIE AS
TYPE TipTableOfRec IS TABLE OF I_TIPOLOGIA%ROWTYPE;
PROCEDURE leggi(resultset IN OUT TipTableOfRec);
END DATABANKER_TIPOLOGIE;
CREATE or REPLACE PACKAGE BODY DATABANKER_TIPOLOGIE AS
PROCEDURE leggi(resultset IN OUT TipTableOfRec) AS
BEGIN
SELECT * BULK COLLECT INTO resultset
FROM I_TIPOLOGIA;
END leggi;
END DATABANKER_TIPOLOGIE;
When I compile the form I receive in QUERY-PROCEDURE trigger
en error 306: "number or type of arguments are wrong in POPULATE_BLOCK"
I post the trigger auto generated by Forms Builder 6i...
DECLARE
bk_data DATABANKER_TIPOLOGIE.TIPTABLEOFREC;
BEGIN
DATABANKER_TIPOLOGIE.leggi3(bk_data);
PLSQL_TABLE.POPULATE_BLOCK(bk_data, 'BLOCCO50'); -- <- error here
END;
How can I solve this problem? Maybe there is a bug?
P.S. I'm using Oracle Database 9i

Answer 1

CREATE or REPLACE PACKAGE DATABANKER_TIPOLOGIE AS
TYPE TipTableOfRec IS TABLE OF I_TIPOLOGIA%ROWTYPE;
PROCEDURE leggi(resultset IN OUT TipTableOfRec);
END DATABANKER_TIPOLOGIE;I have solved with this replacement 1) -> 2)
1) TYPE TipTableOfRec IS TABLE OF I_TIPOLOGIA%ROWTYPE;
2) TYPE TipTableOfRec IS TABLE OF I_TIPOLOGIA%ROWTYPE
INDEX BY BINARY_INTEGER;
with 2) now works.
Now I have stored-procedures for query, insert, delete
and update.
I have some problems with delete and update of the records
because it seems that they are locked.
I think that it is due to the absence of lock
stored-procedure... there's someone that can help me with
the lock SP implementation?
