-> Subject: [GENERAL] finding firstname + lastname groups
->
-> I have to find the same firstname+ lastname combo in my db and see which
name appears the most so I basically need to do the following:
->
-> select name, count(name) from people group by name having count(name)>1
->
-> The problem is name is not one column but made up of firstname,
lastname...how do I do this?
->
-> Thanks!
Use string concatenation :
http://www.postgresql.org/docs/8.3/interactive/functions-string.html#FUNCTIO
NS-STRING-SQL
select firstname || ' ' || lastname as name, count(firstname || lastname)
from people
having count(firstname || lastname) > 1;
