getting error 1418 (HY0000)

[development]

Dear all,

I've recently installed MySQL 5.0.7 in linux machine. I was testing the major feature of 5.0 stored procedure.

I've written very simple procedure for testing

delimiter //
Create procedure test (out p1 int)
begin
select count(*) into p1 from tbl_test;
end //

but it is showing
Error 1418 (HY0000) This routine is declared to be non-deterministic and to modify data and binary logging is enabled (you *might* want to use the less safe log_bin_trust_routine_creators variable)

can anyone explain me what exactly is happening? what should i do for succefully execution of the query?

Thanks in advance

Rushik.
