Concatenation in SELECT

[Alex]

Hi,
is it possible to concatenate two rows (same or different data type)
into one.
like First Name, Last Name or ZIP City etc.

Thanks
Alex

If you meant to concatenate two *columns*, it goes like

SELECT firstname || ' ' || lastname AS fullname FROM ...

or for nullable columns

SELECT coalasce(firstname || ' ', '') ||
coalesce(lastname, '') AS ...

This should work for non-text datatypes as well, because most, if not
all, datatypes have implicit casts to text.
