Обсуждение: Procedure failing after upgrade

All,

I just upgraded to the latest version from 7.2.x and now a procedure is failing.

Please tell me what I'm doing wrong!

Original Func:

SELECT generateinvoice('{123,124}');

CREATE FUNCTION "generateinvoice" (integer[]) RETURNS integer AS '
       DECLARE id_array ALIAS for $1;       temppk INT4;       count_it INT;
       BEGIN       count_it := 1;
               SELECT INTO temppk nextval(''t_invoice_invoice_id_seq'');               INSERT INTO t_invoice
(invoice_id,created_date, invoice_status_id, modified_date) VALUES (temppk, CURRENT_TIMESTAMP(2), ''1'',
CURRENT_TIMESTAMP(2));
       WHILE id_array[count_it] LOOP
                       UPDATE t_event SET invoice_id=temppk, event_status_id=''5'' WHERE event_id=id_array[count_it];
               count_it := count_it + 1;       END LOOP;
       -- TEST COUNT RETURN (count_it - 1);               RETURN temppk;       END;' LANGUAGE 'plpgsql';


My Latest Attempt:

SELECT generateinvoice('{123,124}');

CREATE FUNCTION "generateinvoice" (anyarray) RETURNS integer AS '
DECLAREid_array ALIAS for $1;temppk INT4;count_it INT;
BEGIN    count_it := 1;    SELECT INTO temppk nextval(''t_invoice_invoice_id_seq'');    INSERT INTO t_invoice
(invoice_id,created_date, invoice_status_id, modified_date) VALUES (temppk, CURRENT_TIMESTAMP(2), ''1'',
CURRENT_TIMESTAMP(2));
    WHILE id_array[count_it] LOOP
                                       UPDATE t_project SET invoice_id=temppk, project_status_id=''5'' WHERE
project_id=id_array[count_it];       count_it := count_it + 1;    END LOOP;
 
    RETURN temppk;END;
' LANGUAGE 'plpgsql';

Please include the actual error message produced. That said, I'm getting
an interesting error. It appears as if the integer array type is being
confused for a boolean.
       WHILE id_array[count_it] LOOP

It is expecting WHILE <boolean> LOOP. Make the id_array[count_it]
expression into a boolean rather than an integer. Something like:
       WHILE id_array[count_it] IS NOT NULL LOOP

Are you using 7.4.x now?
If so, I think the problem is condition:       WHILE id_array[count_it] LOOP
Change it to:       WHILE id_array[count_it] NOTNULL LOOP

Up till 7.4, plpgsql's control statements didn't actually check whether
the given expression returned boolean :-(.  They just assumed that the
resulting Datum should be interpreted as a bool.  7.4 will coerce to
bool or throw an error if it can't.
