oci8 and primary key & its speed

first of all thank all of you who helpd me up to now, to make this work now when i make SELECT c.column_name, c.position FROM user_cons_columns, c, user_constraints t WHERE t.table_name='YOURTABLENAME' AND t.constraint_type='P' AND t.constraint_name=c.constraint_name AND t.table_name=c.table_name ORDER BY c.position it is ok and i have it but what i realy need to know is the name of trigger that was fired , so i made this but this one needs minutes why ?? SELECT c.column_name, c.position, tc.trigger_name FROM user_cons_columns c, user_constraints t, all_trigger_cols tc WHERE t.table_name='TR_LOG' AND t.constraint_name=c.constraint_name AND t.table_name=c.table_name and tc.column_name=c.column_name and tc.table_name=t.table_name ORDER BY c.position; now i make one query to find out the name of column , then another one to get the name of trigger( this is fast) but i would like to write a single statement to get the name of trigger because that is the only thing i need actualy but it is to slow
