SQL Code wont take when running in PHPmyADMIN or Navicat

Question

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);


delimiter ;

drop procedure if exists agent_hier;

delimiter #

create procedure agent_hier
(
in p_agent_id int unsigned
)
proc_main:begin

declare done tinyint unsigned default 0;
declare dpth smallint unsigned default 0;


create temporary table hier(
 parent_agent_id int unsigned, 
 agent_id int unsigned, 
 depth smallint unsigned default 0
)engine = memory;

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

/* http://dev.mysql.com/doc/refman/5.0/en/temporary-table-problems.html */

create temporary table tmp engine=memory select * from hier;

while done <> 1 do

    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 
            select a.parent_agent_id, a.agent_id, dpth + 1 from agent a
            inner join tmp on a.parent_agent_id = tmp.agent_id and tmp.depth = dpth;

        set dpth = dpth + 1;            

        truncate table tmp;
        insert into tmp select * from hier where depth = dpth;

    else
        set done = 1;
    end if;

end while;


select 
 a.agent_id,
 a.name as agent_name,
 if(a.agent_id = b.agent_id, null, b.agent_id) as parent_agent_id,
 if(a.agent_id = b.agent_id, null, b.name) as parent_agent_name,
 hier.depth,
 a.commission_level
from 
 hier
inner join agent a on hier.agent_id = a.agent_id
inner join agent b on hier.parent_agent_id = b.agent_id
order by
 -- dont want to sort by depth but by commision instead - i think ??
 -- hier.depth, hier.agent_id; 
 a.commission_level desc;

drop temporary table if exists hier;
drop temporary table if exists tmp;

end proc_main #


delimiter ;


/*

select * from agent;

call agent_hier(1);
call agent_hier(2);
call agent_hier(3);
call agent_hier(5);

Answer 1

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

Answer 2

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
