Re: foreach in sql functions - Mailing list pgsql-general

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';

Subject: [GENERAL] foreach in sql functions


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
