IF statement syntax in SQL script view

Question

I need to include a "IF" condition in the "SELECT" section of my SQL script view.
I tried the following syntax's but I get the error 'Incorrect SQL syntax near 'IF'
1.  IF(Revenue <> '0' AND Quantity <> '0', Revenue/Quantity, '0') AS Gross Price
2.  IF(Revenue != '0' AND Quantity != '0', Revenue/Quantity, '0') AS Gross Price
3.  IF(Revenue <> '0' AND Quantity <> '0' THEN Revenue/Quantity ELSE  '0' END) AS Gross Price
4.  IF(Revenue != '0' AND Quantity != '0' THEN Revenue/Quantity ELSE  '0' END) AS Gross Price
My final SQL would read like follows:
SELECT field1, field2, IF(......) AS field3
FROM table1
Can anybody please help with the correct IF statement syntax to be used in the SQL script based view?

Hi Lakshmi,
below is the syntax for IF statement.
IF <bool_expr1> THEN
<then_stmts1>
ELSEIF <bool_expr2>
THEN <then_stmts2>
[ELSE <else_stmts3>]
END IF
eg :
BEGIN
DECLARE found INT := 1;
SELECT count(*) INTO found FROM books WHERE isbn = :v_isbn;
IF :found = 0 THEN
INSERT INTO books VALUES (:v_isbn, 'In-Memory Data Management', 1, 1, '2011', 42.75, 'EUR');
ELSE
UPDATE books SET price = 42.75 WHERE isbn =:v_isbn;
END IF;
END;
