在MYSQL中以1-2-3-4排...

Question

我正在尝试查找一个给我行'x'的查询：1-2-3-4 ...... 不是3-4-5-6-7 ......

这是我的疑问：

SELECT f1.`week`
    ,count(f2.`week`) AS X
    ,SUM(f2.inn) AS inn
    ,SUM(f2.`out`) AS `out`
FROM (  SELECT `week`
            ,SUM(IF(`etat` = 1,1,0)) AS inn
            ,SUM(IF(`etat` = 2,1,0)) AS `out` 
        FROM fait_stock 
        WHERE `week` BETWEEN 40 AND 51 
        GROUP BY `week`) AS f1 
JOIN (  SELECT `week`
            ,SUM(IF(`etat` = 1,1,0)) AS inn
            ,SUM(IF(`etat` = 2,1,0)) AS `out` 
        FROM fait_stock 
        WHERE `week` BETWEEN 1 AND 51 
        GROUP BY `week`) AS f2
    ON f2.`week` <= f1.`week` 
GROUP BY f1.`week`

这是结果：
