delete from blah b where created = (select min(created) from blah where user_id = b.user_id);

Just be aware that if there is only 1 record for a user, this statement would delete that. I say that just in case you wanted to keep at least 1 record for a particular user (just reading into what you're really doing).

Hi,

Can anyone help me with this delete statement?

I have the following table:

 Name                                      Null?    Type
 ----------------------------------------- -------- -------------
 USER_ID                                   NOT NULL NUMBER(15)
 PASSWORD                                           VARCHAR2(30)
 CREATED                                            DATE

What I need to do is delete the oldest record for a particular user_id. And its doing my head in. Any help appreciated!

Thanks,
Steve.
