can you help me with this issue

In the library database, how many books are with the author of "J.K. Rowling"? Alias the result as jk_book_count. The books table has the columns id, title, author, genre and first_published.

To facilitate analysis and an accurate answer, always show your complete query code, and provide a link to the course page you are working with.

But as a generic hint, people have previously had trouble with this task if they overlook the fact that there is a space between "J.K." and "Rowlling" (or if they omit either of the periods).

sorry here is my code SELECT COUNT(*) AS jk_book_count FROM books WHERE author = "J.K.Rowling";

As I hinted already, it looks like you omitted that space between "J.K." and "Rowlling"!

SELECT COUNT(*) AS jk_book_count FROM books WHERE author = "J.K.Rowling";  -- your code
SELECT COUNT(*) AS jk_book_count FROM books WHERE author = "J.K. Rowling"; -- passing code

sorry master it was not the problem

I'm pretty sure it is, I pasted your code directly into the challenge, and when I added the space it passed.
