Running stored procedures from HTML DB

Question

Hello.
Is it possible to run stored procedures/functions from HTML DB? If yes, how to do it?

Answer 1

If the variable v_return_amount is a number, how can you assign a boolean to it? Are you sure your function is valid? I would write it slightly different:
CREATE OR REPLACE FUNCTION verify_amount (
v_invoices_pk IN NUMBER,
v_new_amount IN NUMBER
RETURN BOOLEAN
IS
CURSOR c_amount
IS
SELECT amount
FROM invoices
WHERE invoices.invoices_pk = v_invoices_pk;
CURSOR c_dist_amount
IS
SELECT SUM (cost_distribution.amount)
FROM cost_distribution
WHERE cost_distribution.invoices_pk = v_invoices_pk;
v_sum_amount NUMBER;
v_invoices_amount NUMBER;
BEGIN
OPEN c_dist_amount;
FETCH c_dist_amount
INTO v_sum_amount;
CLOSE c_dist_amount;
OPEN c_amount;
FETCH c_amount
INTO v_invoices_amount;
CLOSE c_amount;
IF (v_invoices_amount <= v_sum_amount + v_new_amount)
THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
RETURN v_return_amount;
EXCEPTION
WHEN OTHERS
THEN
RETURN FALSE;
END;
Other than that, I am not sure about your cursors but I can't judge from here. The other thing is how you use the function in the validation process. Can you try to correct and tell if it worked out?
