创建一个存储过程pro_4，要求使用游标，根据输入参数给定的图书价格，查看图书表中高于该图书价格的图书id、图书名称、价格。调用pro_4，查询高于50元价格的图书。

好的，以下是创建存储过程pro_4的代码：

CREATE PROCEDURE pro_4
    @price FLOAT
AS
BEGIN
    SET NOCOUNT ON;
    DECLARE @book_id INT;
    DECLARE @book_name NVARCHAR(50);
    DECLARE @book_price FLOAT;
    
    DECLARE book_cursor CURSOR FOR
        SELECT book_id, book_name, book_price
        FROM book_table
        WHERE book_price > @price;
    
    OPEN book_cursor;
    FETCH NEXT FROM book_cursor INTO @book_id, @book_name, @book_price;
    
    WHILE @@FETCH_STATUS = 0
    BEGIN
        PRINT 'Book ID: ' + CAST(@book_id AS NVARCHAR(10)) + ', Book Name: ' + @book_name + ', Book Price: ' + CAST(@book_price AS NVARCHAR(10));
        FETCH NEXT FROM book_cursor INTO @book_id, @book_name, @book_price;
    END
    
    CLOSE book_cursor;
    DEALLOCATE book_cursor;
END

然后调用存储过程pro_4，查询高于50元价格的图书：

EXEC pro_4 @price = 50.0;

注意：这里假设图书表的表名为book_table，图书id为整型，图书名称为nvarchar类型，价格为float类型。如果实际情况不同，请根据实际情况修改代码。
