Quick Java SQL problem

Question

My code:

String sql = "SELECT Publisher.Name, Book.Title, ShopOrder.OrderDate, SUM(OrderLine.Quantity) AS No_Books, "
 + "SUM(OrderLine.UnitSellingPrice * Orderline.Quantity) AS Total_Price"
 + "FROM Publisher, Book, OrderLine, ShopOrder"
 + "WHERE OrderLine.BookID = Book.BookID AND ShopOrder.ShopOrderID = OrderLine.ShopOrderID AND Publisher.PublisherID = Book.PublisherID AND Publisher.PublisherID = " + id
 + "GROUP BY book.title, publisher.name, ShopOrder.OrderDate"
 + "ORDER BY ShopOrder.OrderDate, Book.Title";

Resulting error:

syntax error at or near "Publisher" at char position 166 (Just after the FROM clause)

Answer 1

Theres spaces missing

Your strings is ...S Total_PriceFROM Publisher, Book, OrderLine, ShopOrderWHERE O...

You should use:

String sql = "SELECT Publisher.Name, Book.Title, ShopOrder.OrderDate, SUM(OrderLine.Quantity) AS No_Books, "
 + " SUM(OrderLine.UnitSellingPrice * Orderline.Quantity) AS Total_Price"
 + " FROM Publisher, Book, OrderLine, ShopOrder"
 + " WHERE OrderLine.BookID = Book.BookID AND ShopOrder.ShopOrderID = OrderLine.ShopOrderID AND Publisher.PublisherID = Book.PublisherID AND Publisher.PublisherID = " + id
 + " GROUP BY book.title, publisher.name, ShopOrder.OrderDate"
 + " ORDER BY ShopOrder.OrderDate, Book.Title";

Answer 2

When you concatenate those strings there is no space between Total_Price and FROM. And in other lines similarly. I always end and start a quoted SQL fragment with a space.

Answer 3

You need spaces either at the end of your lines or at the beginning. The resulting string would look like: ...AS Total_PriceFROM Publisher...
