RE: Help Need

Hi,  

This statement will get you the userid and the number of times it is duplicated. Then it's just a case of inserting the value at the desired location. Although this does mean that you are either going to have a column with lots of null values or lots of repeated values...Doesn't really make a lot of sense either way.  

select userid,

         count(userid)-1
   from user
 group by user_id;  

Regards,
Kev.

Hi DBA Gurus,

I have a table called user..

It has userid, firstname, lastname, city, address, telephone, email

There are some userid which have been reentered .. I would like to insert a column called repeats and take the number of times the userid is repeated

How to I go about it

Create table usercheck as (userid, firstname, repeated,lastname, city, address, telephone, email)
As
Select userid, firstname, count(*) userid as repeated,,lastname, city, address, telephone, email)
>From user;

Something like this..

For example the userid of Deewaker is 123123 and he as been inserted 5 times in the table USER the Repeated should give a count of 4.

Please help me.

with warm regards,
