pl/pgsql function problem - Mailing list pgsql-novice

I am having problems doing what seems to be a very simple thing.  All I
need is to join 2 or more variables (eg char, int, date) and return them
as a single varchar variable.

eg ret := int + char + date; or berrer still join("+", int,char,date)
return ret;

Please can anyone help.

Thanks in advance David Mulcahy.
