SQL - 自动分页目录

时间：2016-02-17 14:03:23

标签： sql sql-server logic

我正在构建一个模型，用产品自动填充（分页）目录。

我有一个正在运行的订单，每个产品应该收到的空间分配（1/8 1/4 1/2 3/4 1/1页）。

我需要有关如何将产品细分到页面上的想法。没有太多的空间浪费。

E.g。第1部分需要1/8页第2部分需要整页...正常逻辑会将第2部分放在下一页上。常识会将它们放在一起。 （这个例子会有很多变化）。

无法更改正在运行的订单。

如果我理解正确，那么我认为这会给你你想要的东西：

;WITH MyCTE AS
(
SELECT
    productid,
    pages,
    SUM(pages) OVER (ORDER BY pagination_order) AS current_page_unrounded
FROM
    #tt1
)
SELECT
    productid,
    pages,
    CEILING(current_page_unrounded) AS page_number
FROM
    MyCTE

SUM的窗口使用可让您获得总计，然后您只需使用CEILING向上舍入到产品出现的页码。

请注意，这将不惜一切代价保留分页顺序，因此不会对页面进行适当的优化。
