SQL Code wont take when running in PHPmyADMIN or Navicat
I have the following code but it keeps presenting errors. The first part of the code creates the necessary table followed by - what should create stored procedures but it does not.
any ideas?
drop table if exists agent;
create table agent
(
agent_id int unsigned not null auto_increment primary key,
name varchar(32) not null,
commission_level tinyint unsigned default 0,
parent_agent_id int unsigned default null
)
engine = innodb;
insert into agent (name, commission_level, parent_agent_id) values
('I', 99, null),
('A', 7, 1),
('B', 6, 1),
('C', 5, 2),
('D', 6, 2),
('E', 5, 3),
('F', 2, 3),
('G', 5, 5),
('H', 1, 5);

create procedure agent_hier

insert into hier values (p_agent_id, p_agent_id, dpth);

if exists( select 1 from agent a inner join hier on a.parent_agent_id = hier.agent_id and hier.depth = dpth) then
insert into hier

i've made a navicrap compatible script for you here http://pastie.org/1112694 - should run fine now providing you have the relevant privileges :P
Affected rows: 0 Time: 0.001ms
I tried your SQL code, and works for me, I assume your user account doesn't have the correct privileges?
try
SHOW GRANTS;
and make sure that the user has the "Create routine" privileges
