Subject: SELECT syntax synopsis: column_definition?
Date: Tue, 21 Aug 2007 12:34:27 -0700 (PDT)
Message-ID: <830878.14424.qm@web31803.mail.mud.yahoo.com> (raw)

Can any one give an example of the difference between a column_alias and a column_definition when
using a function in the FROM clause?

from the manual:
http://www.postgresql.org/docs/8.2/interactive/sql-select.html

"function_name ( [ argument [, ...] ] ) [ AS ] alias [ ( column_alias [, ...] | column_definition
[, ...] ) ]"

Regards,
Richard Broersma Jr.
