PLS-00306

Question

Hey All
I am using microsoft reporting services 2000, to develop a report. I am using a stored procedure to fetch data from the oracle DB and display on the report GUI.
Initially it was working when my signature was something like this:
PROCEDURE danger_cards (
          startDate IN DATE,
          endDate IN DATE,
          serviceCenter IN VARCHAR2,
dangerCards OUT staging_reports.REFERENCE_CURSOR)
but when i changed the signature to :
PROCEDURE danger_cards (
          startDate IN DATE,
          endDate IN DATE,
          serviceCenter IN VARCHAR2,
errorMessage OUT VARCHAR2,
dangerCards OUT staging_reports.REFERENCE_CURSOR)
it is giving this error:
Could not generate a list of fields for the query
Check the query syntax or click Refresh Fields on the query toolbar.
ORA-06550: Line 1, Column 7:
PLS-00306: wrong number or types of arguments in call to 'STAGING_REPORTS.DANGER_CARDS'
ORA-06550: Line 1, Column 7:
PL/SQL : Statement ignored
Since it was working before, and not now, i presume me adding the out field errorMessage in the signature as an OUT param is the reason.
Please let me know, what might be the reason for such kind of an error.
The body of the stored proc currently looks like this:
PACKAGE BODY "STAGING_REPORTS" AS
PROCEDURE danger_cards (
          startDate IN DATE,
          endDate IN DATE,
          serviceCenter IN VARCHAR2,
errorMessage OUT VARCHAR2,
dangerCards OUT staging_reports.REFERENCE_CURSOR)
IS
dangerCard AD_REPORT_DANGER_CARDS_VW%ROWTYPE;
date_range EXCEPTION;
PRAGMA EXCEPTION_INIT(date_range, -20999);
BEGIN
errorMessage := '';
IF(startDate > endDate)
THEN
raise_application_error(-20999,'Please Specify An End Date Greater Or Equal To The Start Date');
END IF;
          OPEN dangerCards
          FOR
               SELECT      *
               FROM AD_REPORT_DANGER_CARDS_VW
               WHERE COMPLETION_DTE >= TO_CHAR(startDate,'YYYYMMDD')
               AND
               COMPLETION_DTE <= TO_CHAR(endDate,'YYYYMMDD')
               AND
               (SERVICE_AREA_GEO_CD = serviceCenter);
EXCEPTION
WHEN date_range THEN
errorMessage := SQLERRM;
END staging_reports_danger_cards;
END staging_reports;

Hi,
If you have a look at the error message:PLS-00306: wrong number or types of arguments in call to 'STAGING_REPORTS.DANGER_CARDS'you'll notice that the error is when calling the procedure. You should check the whole package and other ones too for calls of the DANGER_CARDS procedure.
Just issue:SELECT NAME, TEXT
FROM DBA_SOURCE
WHERE UPPER(TEXT) LIKE '%DANGER_CARDS%';and sort the result in order to check against the proc definition. You can also paste this query output here, or the whole package code, in order for us to diagnose it more precisely.
