Access DB：TOP 子句和嵌套查询 + PHP Paging

Question

我正在开发一个 PHP 界面来显示来自两个不同数据库的一些结果：一个 MySQL 数据库 (.sql) 和一个 Access 数据库 (.mdb)。当我查询结果时，我让用户选择他想列出多少个，这样我就可以通过一些 PHP 乐趣来限制和分页。
这对于 MySQL 数据库来说是完美的工作，其中 LIMIT 子句以一种简洁的方式完成所有事情。 Access DB 是另一回事：Access 没有 LIMIT 子句，所以我必须使用 TOP 子句。太糟糕了，这让分页变得很痛苦。
我在this question 的已接受答案中找到了一个很好的例子，但我遇到了问题。首先，让我向您展示几个 sn-p 查询：

查询 #1

SELECT TOP 5 *                 
FROM `Table_1` INNER JOIN `Table_2`
ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID`
AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp`
WHERE `Table_1`.`Some_ID` LIKE 'ID %' AND `Table_1`.`Timestamp` LIKE '2018/03/20 %';

查询 #2

SELECT TOP 5 *                 
FROM `Table_1` INNER JOIN `Table_2`
ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID`
AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp`
WHERE `Table_1`.`Some_ID` LIKE 'ID %' AND `Table_1`.`Timestamp` LIKE '2018/03/20 %'
ORDER BY `Table_1`.`Some_ID`;

查询 #1 只向我显示了前 5 个结果。
太糟糕了，当我添加 ORDER BY 子句时，Query #2 会返回所有满足我条件的结果。

这样的 MySQL 查询不会发生同样的事情：

查询 #3

SELECT * 
FROM `Table_1` INNER JOIN `Table_2`
ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID` 
AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp` 
WHERE `Table_1`.`Some_ID` LIKE 'ID %' AND `Table_1`.`Timestamp` LIKE '2018/03/20 %'
ORDER BY `Table_1`.`Some_ID`
LIMIT 0, 5;

那么，我的 Access 查询是否有问题？
为了完成我的问题，这就是我的最终 Access 查询的样子（我稍微修改了上述主题中提出的那个）：

查询 #4

SELECT * 
FROM `Table_1` INNER JOIN `Table_2` 
ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID` 
AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp` 
WHERE EXISTS (
    SELECT TOP 5 * FROM (
        SELECT TOP 10 * 
        FROM `Table_1` INNER JOIN `Table_2` 
        ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID` 
        AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp` 
        WHERE `Table_1`.`Some_ID` LIKE 'ID %' AND `Table_1`.`Timestamp` LIKE '2018/03/20 %') 
    ORDER BY `Table_1`.`Some_ID` DESC) 
ORDER BY `Table_1`.`Some_ID` ASC;

Answer 1

我终于设法解决了我的问题。我会发布我的查询，以防其他人遇到同样的问题。

SELECT TOP 5 *
FROM `Table_1` INNER JOIN `Table_2`
ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID`
AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp`
WHERE `Table_1`.`Timestamp`
IN (
    SELECT TOP 5 `Table_1`.`Timestamp`
    FROM (
        SELECT TOP 10 *
        FROM `Table_1` INNER JOIN `Table_2`
        ON `Table_1`.`Some_ID` = `Table_2`.`Some_ID`
        AND `Table_1`.`Timestamp` = `Table_2`.`Timestamp`
        WHERE `Table_1`.`Some_ID` LIKE 'ID %'
        AND `Table_2`.`Timestamp` LIKE '2018/03/20 %'
        ORDER BY `Table_1`.`Timestamp` ASC)
    ORDER BY `Table_1`.`Timestamp` DESC)
ORDER BY `Table_1`.`Timestamp` ASC;

只需使用“ASC”和“DESC”即可获得您愿意返回的结果。
