Re: foreach in sql functions

Hi,

I have tried to run the plpgsql script supplied by Oleg but I run into an
error that I don't understand. Can anyone shed some light on it for me - it
reads

NOTICE: Line 6 at open
ERROR: Relation "prd" does not exist

Thank you

Zac

Try something along the following lines:

DROP FUNCTION crt_bsk_dtl (INTEGER);
CREATE FUNCTION crt_bsk_dtl (INTEGER) RETURNS INTEGER AS '
DECLARE curs CURSOR FOR
SELECT PrdKey FROM Prd WHERE Sts < 999;
DECLARE
rec RECORD;
BEGIN
OPEN curs;
LOOP
-- fetch next record
FETCH curs INTO rec;
EXIT WHEN NOT FOUND;

INSERT INTO BskDtl (BskKey, PrdKey) VALUES ($1,
rec.PrdKey);
END LOOP;
CLOSE curs;


RETURN 1;

END;
' language 'plpgsql';

Hi All,

I have only recently started using pgsql and would like to try some
internal functions as it appears this would be quicker than running
similar functions from php.

Is it possible to write sql functions with a foreach style loop?


CREATE FUNCTION crt_bsk_dtl(integer) RETURNS integer AS '

SELECT PrdKey FROM Prd WHERE Sts < 999;

foreach(Prd.PrdKey){

    INSERT INTO BskDtl (BskKey, PrdKey) VALUES ($1, Prd.PrdKey);

}

SELECT 1;
' LANGUAGE SQL


Any help or pointers very much appreciated.

Thanks

Zac
