Question

Hi,
I'm triying to execute the SP that I describe below and the OS give me an error:
CREATE OR REPLACE PROCEDURE DWARE.P_CSCV_AGR_MONTH_REVENUE

Thanks in advance...

Hi,
Your procedure's signature is
CREATE OR REPLACE PROCEDURE DWARE.P_CSCV_AGR_MONTH_REVENUE
TBL_NAME VARCHAR2,
START_DATE DATE,
RESULT_ OUT NUMBER
) i.e. it is expecting two input parameters, TBL_NAME in VARCHAR2 format and the other START_DATE in DATE format. Also you need a variable with data type as NUMBER to hold the value of OUT parameter RESULT_
Now look at the way you are calling this procedure
BEGIN
DWARE.P_CSCV_AGR_MONTH_REVENUE(CSCV_AGR_MONTH_REVENUE,'01/01/2010');
END;
/first parameter has to be a VARCHAR2, so enclose CSCV_AGR_MONTH_REVENUE into single quotes.
second parameter should be a date, so use to_date() function.
Lastly declare a variable with data type as Number for holding value of out parameter RESULT_
Something like this :
declare
t_num number;
begin
a('CSCV_AGR_MONTH_REVENUE',to_date('01/01/2010','MM/DD/YYYY'),t_num);
dbms_output.put_line(t_num);
end;Vivek L
