Question

SQL Server 2000. Single table has a list of users that includes a unique user ID and a non-unique user name.

I want to search the table and list out any users that share the same non-unique user name. For example, my table looks like this:

ID   User Name   Name
==   =========   ====
0    parker      Peter Parker
1    parker      Mary Jane Parker      
2    heroman     Joseph (Joey) Carter Jones
3    thehulk     Bruce Banner

What I want to do is do a SELECT and have the result set be:

ID   User Name   Name
==   =========   ====
0    parker      Peter Parker
1    parker      Mary Jane Parker   

from my table.

I’m not a T-SQL guru. I can do the basic joins and such, but I’m thinking there must be an elegant way of doing this. Barring elegance, there must be ANY way of doing this.

I appreciate any methods that you can help me with on this topic. Thanks!

One way

select t1.* from Table t1
join(
select username from Table
group by username
having count(username) >1) t2 on t1.username = t2.username
