Delete Record In Update Trigger?

May 24, 2012

the following case is successfully done with mssql databases.

Case:

Table UserGroup
Columns id, name, handshake

When the handshake is set to 'd', this record should be deleted. I know it is bad behaviour by design.

What have I done so far:

- created an after update trigger (mutual error) Caused by trying a delete action in the update action, not possible.

- created a view in combination of instead of update trigger.

This causes also mutual error, or if ignored (PRAGMA AUTONOMOUS_TRANSACTION), an deadlock.

Code so far:

create or replace procedure Delete_UserGroup_sp(p_groupId in USER_GROUP.HMIUSERGROUPID%TYPE, p_handshake in USER_GROUP.HANDSHAKE%TYPE)
is
begin
if p_handshake = 'd' then
delete USER_GROUP WHERE HMIUSERGROUPID = p_groupId;
commit;
end if;
end;

create or replace view USERGROUP_V as select * from USER_GROUP

create or replace trigger USER_GROUP_T1
instead of update on USERGROUP_V
for each row
declare
PRAGMA AUTONOMOUS_TRANSACTION;
begin
Delete_UserGroup_sp(:new.HMIUSERGROUPID, :new.HANDSHAKE);
end;
