Hi!

I have a MySQL table with perid (person id), CaseId (the latter two fields are 
varchar).  

The persons (perid) can be on more than one case.  They can get married and 
change caseids, or they can come of age and get their own caseid.  So a given 
perid can be associated with multiple caseids.

I'd like (using just sql) to create a list of those people (perids) who have 
changed cases.  So the list would show a perid and then a bunch of cases that 
they have been on.

My second question is, in MySql can we query a field just created in the query? 
 So can you do something like this?  sele count(*) as cnt, lastname from 
tablename where cnt>1   Here we are using a created field name in the query 
itself.  Is this possible?

Thanks heaps!

-Warren
