Thank you Tom, I am up and running now. For the archives, the
following code is performing as expected:
CREATE TABLE ForecastData(type TEXT, item TEXT, descr TEXT, unit TEXT,
qty FLOAT, rate FLOAT, amt FLOAT);
CREATE OR REPLACE FUNCTION CreateDefaultForecasts(INTEGER) RETURNS
SETOF ForecastData AS '
DECLARE Answers ForecastData;
BEGIN
SELECT ''old'' as type, ''item'' as item, ''descr'' as descr,
''unit'' as unit, $1 as qty, 0 as rate, 0 as amt into answers;
RETURN NEXT Answers;
SELECT ''old'' as type, ''item'' as item, ''descr'' as descr,
''unit'' as unit, $1 + 1 as qty, 0 as rate, 0 as amt into answers;
RETURN NEXT Answers;
RETURN;
END;
' LANGUAGE 'plpgsql';
Cheers,
Coby
