mysql: altered function but stays old function - mysql

Question

I changed a column name in a table, and i needed to change a function for it. So i changed the function. But it still runs the old function! it gives me :
"Error Code: 1054 Unknown column 'avDoctorID' in 'where clause'"
and i'm sure i changed the function because if i see the function itself it is the new one! how can this be?
i did this in mysql workbench, and if i see the function in any other program it show the new function, but gives the same error when i try to run it.
This is the query to run it
select FNC_CreateAppointment(8,1,"2012-08-06","15:30:00","something");
And this it the function itself:
DELIMITER $$
CREATE DEFINER=`root`#`%` FUNCTION `fnc_CreateAppointment`(clid int,calid int,appdate date,apptime time,commentaar varchar(3000)) RETURNS tinyint(1)
BEGIN
declare succeeded boolean;
declare id2 int;
declare id int;
declare dagweek int;
Declare afwezig int;
set afwezig = 0;
set dagweek = Dayofweek(appdate);
set id =0;
set id2 = 0;
set succeeded = false;
select availableID into id from tbl_available where AVdays = dagweek and AVHours = apptime and avCalendarID = calid
;
if id > 0
then
select appointmentID into id2 from tbl_appointment where appointmentDate = appdate and appointmentTime = apptime and CalendarID = calid;
if id2 = 0
then
select AbsentID into afwezig from tbl_absent where abHoliday = appdate and abAbsent = apptime and abCalendarID = calid;
if afwezig = 0 then
insert into tbl_appointment(clientId,Calendarid,appointmentDate,appointmenttime,remark)
Values
(clid,calid,appdate,apptime,commentaar);
set succeeded = true;
end if;
end if;
end if;
return succeeded;
END
the error returned is:
call db_demo.FNC_CreateAppointment(8,1,"2012-08-06","15:30:00","something") Error Code: 1054 Unknown column 'avDoctorID' in 'where clause'
'avDoctorID' is the old column

Answer 1

You might need to drop the function first and then run the CREATE statement again.
DROP FUNCTION IF EXISTS `<function_name>`
