how about
select rowid,p_id,p_name
from p_answer pa
where rowid > (select min(pa2.rowid)
from p_answer pa2
where pa.p_id = pa2.p_id and pa.p_name = pa2.p_name)
This will display the p_id,p_name and rowid of all the duplicate rows that have the same p_id and p_name.
>>> Larry Taylor <ltaylor_at_iq.com> 02/20/01 11:56AM >>> Hi all,
How can I find duplicate keys and drop the duplicate? My database is 8.1.6
and I tried the following
and got this error:
CREATE UNIQUE INDEX I_SA_C_OWNERID_C_NAME ON P_ANSWER (P_ID , P_NAME ) PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 65536) LOGGING TABLESPACE USERS; ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys found
Thanks in advance.
Larry
