Mysql 选择成员总数和支付金额

我需要帮助为MySQL数据库生成SQL

我有三张桌子：

开办组织 成员 付款 组织表：

成员表：

付款表：

如何选择以下选项

应具有以下输出：

+------------+-------------------+--------+-----------------+---------------+--------------+ 
|  Org name  |  Revenue          |untransferred amount      | Total members | last 30 days |
+------------+-------------------+--------------------------+---------------+--------------+
| AAA        | 150               | 0                        | 3             |  2           |
|-----------------------------------------------------------+---------------+--------------+
| BBB        | 200               | 200                      | 1             |  0           |   
+------------+-------------------+--------------------------+---------------+--------------+


Org name              = organisation name
Revenue               = Total amount received
untransferred amount  = transferred_at is null (payments table)
Total members         = total members joined till today
last 30 days          = total members joined last 30 days

您需要联接表、对结果进行分组并选择所需的逻辑：

SELECT   org.name,
         SUM(pmt.amount) AS revenue,
         SUM(IF(pmt.transferred_at IS NULL, pmt.amount, 0)) AS untransferred
FROM     Organisations org
    JOIN Members       mem ON mem.organisation_id = org.id
    JOIN Payments      pmt ON pmt.member_id       = mem.id
GROUP BY org.id

谢谢您的回答。我可以用php运行这个查询吗？谢谢。sumifjoin\u date>=curdate-间隔30天，1，0为最后一个\u 30\d此行是否给出错误？对不起，我是SQL新手。我可能遗漏了什么。忘记了一个妄想，trz now错误：“on子句”中的未知列“o.organization\u id”：选择o.name，sumamount作为收入，SumIFTransfered\u at为null，amount，0作为未转换的\u ammt，sumifjoin\u date>=curdate-间隔30天，1，0作为来自组织的最后一个\u 30 \u d o内部加入成员m on o.organization\u id=m.organization\u id内部加入付款p on p.member\u id=m.member\u id按1付款金额分组，0作为未转移的sumifjoin\u日期>=curdate-间隔30天，1，0作为组织的最后一个\u 30 \u d加入mem.organization上的成员mem\u id=org.id加入pmt上的付款pmt.member\u id=mem.id按org.id分组您的查询缺少逗号，因为untransferred>comma=curdate
