Question

尝试将一个SQL查询放在一起，将数据分类到财务年度（我已经排序），然后根据claim_id列中的每个不同值对其进行求和

表格结构是：声明（id，claim_id，日期，金额）

到目前为止的SQL是：

 SELECT
    CASE 
       WHEN MONTH(date)>=4 THEN
            concat(YEAR(date), '-',YEAR(date)+1)
       ELSE 
            concat(YEAR(date)-1,'-', YEAR(date)) 
    END AS fyear,
    SUM(amount) AS total, claim_id
 FROM claim  
 GROUP BY fyear, claim_id 
 ORDER BY claim_id ASC, date ASC

目前我正在接受这个

Array
(
    [fyear] => 2009-2010
    [total] => 567.89
    [claim_id] => 1
)

哪个非常接近，当然因为GROUP BY claim_id我为每个不同的claim_id获取了另一个数组：

Array
(
    [fyear] => 2009-2010
    [total] => 106.76
    [claim_id] => 2
)

我真正喜欢的是：

Array
(
    [fyear] => 2009-2010
    [total1] => 567.89
    [total2] => 106.76
)

有什么建议吗？

谢谢！

会是什么......

SELECT * FROM
    SELECT (CASE 
                WHEN MONTH(date)>=4 THEN
                     concat(YEAR(date), '-',YEAR(date)+1)
                ELSE 
                     concat(YEAR(date)-1,'-', YEAR(date)) 
                END AS fyear,
                SUM(amount) AS total, claim_id
        FROM claim
        WHERE claim_id = 1
        GROUP BY fyear
        ORDER BY date ASC),
    SELECT (CASE 
                WHEN MONTH(date)>=4 THEN
                     concat(YEAR(date), '-',YEAR(date)+1)
                ELSE 
                     concat(YEAR(date)-1,'-', YEAR(date)) 
                END AS fyear,
                SUM(amount) AS total, claim_id)
        FROM claim
        WHERE claim_id = 2
        GROUP BY fyear
        ORDER BY date ASC)
    FROM dual;

有用吗？

将您现有的查询包装在另一个SELECT并使用GROUP_CONCAT可能会完成您的工作。我已经测试了SQL本身，但不确定结果是否符合您的要求 - 所有总计将以逗号分隔列表的形式显示在一列中：

SELECT fyear, GROUP_CONCAT(total) FROM (
    SELECT
        CASE 
           WHEN MONTH(date)>=4 THEN
                concat(YEAR(date), '-',YEAR(date)+1)
           ELSE 
                concat(YEAR(date)-1,'-', YEAR(date)) 
        END AS fyear,
        SUM(amount) AS total, claim_id
    FROM table1  
    GROUP BY fyear, claim_id 
    ORDER BY claim_id ASC, date ASC
) AS totals GROUP BY fyear;

不同行的SQL SUM ....我被卡住了！
