hello... i am faced with an enigma.

SQL> select * from p_sku@shopowner_lnk where sku_cd not in
  2  (select sku_cd from p_sku);

no rows selected

SQL> delete from  p_sku@shopowner_lnk where sku_cd not in (
  2  select sku_cd from p_sku);


2 rows deleted.

there are no triggers on any of these objects. 

SQL> select * from dba_triggers where table_name like '%SKU%';

no rows selected


this 8.1.6 db lives on sun-ultra 60 (solaris).

if there are no rows returned for the select statement, how can there be a
delete? i'm trying to solve a problem for progammers. any feedback would
be most appreciated.

thanks,
kris austin
