Hi ,
I am new to SAP HANA script. I am learning SQL script by seeing the SQL script tutorial in the SAP HANA technical documents folder.
I was trying to run the below procedure but I am getting the error like Physical table is not allowed in OUT table variable position: OP_SALES_BOOKS. But I used physical row type table in the call statement to store the result . But for this procedure I am getting error .
CREATE PROCEDURE addDiscount( IN it_books tt_sales_books, OUT ot_books tt_sales_books)
LANGUAGE SQLSCRIPT READS SQL DATA AS
BEGIN
ot_Books = SELECT title, CASE WHEN price > 300 THEN (price - (price / 30))
ELSE CASE WHEN price > 200 THEN (price - (price / 20))
ELSE (price - (price / 10))
END
END AS price, crcy
FROM :it_books;
END;
CREATE PROCEDURE getSalesBooks( IN minPrice DECIMAL(5, 2), IN currency VARCHAR(3),
IN it_books books, OUT ot_sales tt_sales_books)
LANGUAGE SQLSCRIPT READS SQL DATA WITH RESULT VIEW addDiscount_RET AS
BEGIN
lt_expensive_books = SELECT title, price, crcy
FROM :it_books
WHERE price > :minPrice
AND crcy = :currency;
CALL addDiscount(:lt_expensive_books, lt_on_sale);
lt_cheap_books = SELECT title, price, crcy
FROM :it_books
WHERE price <= :minPrice
AND crcy = :currency;
ot_sales = CE_UNION_ALL(:lt_on_sale, :lt_cheap_books);
END;
CALL getSalesBooks(1.5, '''EUR''', books, op_sales_books);
Please help me how to resolve this issue.
Thanks & Regards,
Ramana.
