Обсуждение: A cute little function

Folks,

Here's a useful one:

CREATE FUNCTION qf_year_quarter (DATETIME) RETURNS VARCHAR AS '
SELECT CAST(CAST(EXTRACT(year FROM $1) AS VARCHAR) ||    '' Q'' || CAST(EXTRACT (quarter FROM $1) AS VARCHAR) AS
VARCHAR);'
LANGUAGE 'sql';

SELECT qf_year_quarter('1999-11-01'::DATETIME);
--------------
1999 Q4
