Mysql 如何从表1中联接2个sql（sum（表1）和count（表2））并按日期分组？

第一个表和第二个表按id_进行关联

在表1中查询为“销售表”

结果1

表2中查询为“明细销售表”

结果2

我想要的是这个

这就是我尝试过的

 select bt.tanggal as date_sold, count(bt.kd_op_beli_tunai) as quantity_id_sold, sum(rbt.harga_satuan * rbt.jumlah) as total_sold
    from t_pembelian_tunai as bt, t_rinci_beli_tunai as rbt
    where bt.kd_op_beli_tunai = rbt.kd_op_beli_tunai
    GROUP by tanggal
    ORDER by tanggal DESC

结果是

---

您可以尝试此查询

SELECT  bt.tanggal as date_sold,bt.quantity_id_sold,rbt.total_sold
FROM
(
    select kd_op_beli_tunai,
           tanggal, 
           count(kd_op_beli_tunai) as quantity_id_sold
    from t_pembelian_tunai
    group by tanggal,kd_op_beli_tunai
)bt
INNER JOIN 
(
    select kd_op_beli_tunai, sum(harga_satuan * jumlah) as total_sold
    from t_rinci_beli_tunai
    group by kd_op_beli_tunai
)rbt on bt.kd_op_beli_tunai = rbt.kd_op_beli_tunai 
ORDER by bt.tanggal

使用平均值而不是计数。从计数（bt.kd_op_beli_tunai）？avg（bt.kd_op_beli_tunai）是否在1号答复前关闭？请提供

t pembelian_tunai

和

t rinci_beli_tunai

表格中的一些样本数据？

 select bt.tanggal as date_sold, count(bt.kd_op_beli_tunai) as quantity_id_sold, sum(rbt.harga_satuan * rbt.jumlah) as total_sold
    from t_pembelian_tunai as bt, t_rinci_beli_tunai as rbt
    where bt.kd_op_beli_tunai = rbt.kd_op_beli_tunai
    GROUP by tanggal
    ORDER by tanggal DESC

SELECT  bt.tanggal as date_sold,bt.quantity_id_sold,rbt.total_sold
FROM
(
    select kd_op_beli_tunai,
           tanggal, 
           count(kd_op_beli_tunai) as quantity_id_sold
    from t_pembelian_tunai
    group by tanggal,kd_op_beli_tunai
)bt
INNER JOIN 
(
    select kd_op_beli_tunai, sum(harga_satuan * jumlah) as total_sold
    from t_rinci_beli_tunai
    group by kd_op_beli_tunai
)rbt on bt.kd_op_beli_tunai = rbt.kd_op_beli_tunai 
ORDER by bt.tanggal
