我需要能够对一列(小时)求和,它与其他列中的几个条件匹配。这就是表格的样子。

payrollid, agentid, ptid, serviceid, dateincurred ,hours
209      , 284    , 580 , 1320     , '2014-05-19' ,4
209      , 284    , 569 , 1433     , '2014-45-19' ,2

209      , 284    , 580 , 1320     , '2014-05-30' ,1
209      , 284    , 569 , 1347     , '2014-05-30' ,5
209      , 284    , 580 , 1326     , '2014-05-31' ,1
209      , 284    , 580 , 1348     , '2014-06-01' ,1
209      , 284    , 580 ,   24     , '2014-06-01' ,1

查询如下所示:

SELECT
    p.agentid,
    p.ptid,
    p.dateincurred,
    p.serviceid,

    (
    SELECT 
        GROUP_CONCAT(p.hours) 
    FROM payroll_detail_temp p3
    WHERE p3.payrollid = '209'
    AND (
            p3.dateincurred BETWEEN '2014-05-19'
            AND DATE_ADD('2014-05-19', INTERVAL 6 DAY))
            AND p3.serviceid = p.serviceid
            GROUP BY
                p3.serviceid
            LIMIT 1
        ) AS week1,

        (
        SELECT
            GROUP_CONCAT(p2.hours)
        FROM
            payroll_detail_temp p2
        WHERE
            p2.payrollid = '209'
        AND (
            p2.dateincurred BETWEEN '2014-05-25'
            AND DATE_ADD('2014-05-25', INTERVAL 6 DAY))
            AND p2.serviceid = p.serviceid
        GROUP BY
            p2.serviceid,
            p2.dateincurred
        LIMIT 1
    ) AS week2,
    GROUP_CONCAT(p.serviceid) AS services,
    GROUP_CONCAT(p.dateincurred) AS dates
FROM
    payroll_detail_temp p
    INNER JOIN agent ON (p.agentid = agent.id)
    INNER JOIN service ON (p.serviceid = service.id)
    INNER JOIN payer ON (p.payerid = payer.id)
    INNER JOIN prov ON (p.provid = prov.id)
    INNER JOIN patient ON (p.ptid = patient.id)
WHERE
    p.payrollid = '209'
    AND (
        p.dateincurred BETWEEN '2014-05-19'
        AND DATE_ADD('2014-05-25', INTERVAL 14 DAY)
    )
GROUP BY
    p.serviceid,
    p.dateincurred

第1周和第2周列表示2周工作时间,在本例中为2014-05-19和2014-06-01。因此,Week1列将分组agentid,ptid,serviceid匹配和dateincurred的小时数,范围为2014-05-19到2014-05-25。同样适用于第2周,其中dateincurred在2014-05-26至2014-06-01之间。

我的查询问题是我得到了重复项,就像下面查询结果中显示的最后两个结果一样。 Week1应该有9.00和Week2需要为null;同样在第1周以下的行应为null,第2周为4.00。第5行和第5行也可以看到相同的情况。 6.在第5行,第1周应为7.00,4.00和1.00,第2周应为空。第6行不应该存在。

我知道存在重复项,因为dateincurred字段与查询重叠,但我无法想象它周围的其他任何内容。

如果您有第一张照片中显示的表格。然后,您可以通过此查询轻松实现所需内容:

SELECT
 PAYROLLID,
 AGENTID,
 PTID,
 SERVICEID,
 DATEINCURED,
 CASE WHEN (DATEINCURRED BETWEEN '2014-05-19' AND '2014-05-25') THEN SUM(HOURS) END WEEK1,
 CASE WHEN (DATEINCURRED BETWEEN '2014-05-26' AND '2014-06-01') THEN SUM(HOURS) END WEEK2
FROM
 YOUR_TABLE_NAME
GROUP BY
PAYROLLID,
AGENTID;
