Question

I am writing an Iphone app and using sqlite as my database. I have 10 objects and I need to order them by their category id. All the id are numbers (starting from 1 to 10).

The sql statement looks like this: SELECT * FROM PACKAGE ORDER BY CATEGORYID ASC

When I query, the result shows 1,10,2,3,4….9.

How do i solve this?

Answer 1

maybe it’s because that the categoryID is TEXT

SELECT * FROM PACKAGE ORDER BY CAST(CategoryID as INTEGER) ASC;
