Users belonging to a group

Question

Hello,
I want to make a (daily) job in which i send an email to application express users belonging to a certain group.
Where in the database can i find the groups a user belongs to ?
The users are in the APEX_WORKSPACE_APEX_USERS view, but where are the groups.
When i run the following procedure on a sql*plus client on my machine, it doesn't give the groups; when i run this command from apex (sql workshop), it does ? What can be the reason for that ?
declare
regel varchar2(20000);
cursor c_u is
select *
from APEX_WORKSPACE_APEX_USERS au;
begin
for l_u in c_u loop
regel := APEX_UTIL.GET_GROUPS_USER_BELONGS_TO(p_username => l_u.user_name);
dbms_output.put_line(l_u.user_name || ',' || l_u.email || ',' || regel);
end loop;
end;

Sjang,
APEX_UTIL.GET_GROUPS_USER_BELONGS_TO requires the workspace ID global package variable to be set, which is not the case in SQL*Plus, unless you set it.
Try connecting as a schema that is mapped to the workspace you're interested in and do this:
begin
wwv_flow_api.set_security_group_id;
end;
If the schema is mapped to more than one workspace, you need to do it like this:
begin
wwv_flow_api.set_security_group_id(99999999999999999);
end;
...replacing all those nines with the result of this query in SQL Workshop (connected in the appropriate workspace):
select v('WORKSPACE_ID') from dual;
Then try the query.
You should be able to do that in your job as well.
