It is a doubt.What do the "deterninistic" option do?
You ever gave me the follow example:
---------------------------------------------
create procedure unsafe_sp()
begin
if @@server_id=2 then
drop databaseaccounting;
enf if;
end
---------------------------------------------
This is a non-deterninistic procedure.
In your word,The procedure can work in master and slave without any warning
.But the procedure should produce different results on master and slave if
master has server_id=1 and slave has server_id=2.
If i add "deterninistic" option in the procedure.As follow:
---------------------------------------------
create procedure unsafe_sp()
DETERMINISTIC
begin
if @@server_id=2 then
drop databaseaccounting;
enf if;
end
---------------------------------------------
In your word,syntax check doesn't find the error and the procedure be executed
without warning,too.And the different result also produce in the master and
slave.
What ever "DETERMINISTIC" option do?
