--Transaction confirmation
IF W_CK = 1 THEN
SELECT SUM(LINE_TOTAL) INTO W_SUBT FROM LINE
WHERE
--checking the invoice for the desired invoice number
LINE.INV_NUMBER = W_IN;
W_TAX :=W_SUBT * 0.08;
--updating the invoice
UPDATE INVOICE
--setting the new values
SET INV_SUBTOTAL = W_SUBT,
INV_TAX = W_TAX,
INV_TOTAL =W_SUBT + W_TAX
WHERE INV_NUMBER = W_IN;
--ending the if statement
END IF;
--ending the procedure
