Question

我需要查询的结果是：

Company 1 | SUM of amount_invoice
Company 2 | SUM of amount_invoice
...

我得到86,000行-每个发票金额分别显示。如果不必先将结果转换为excel即可按我的需要格式化结果，那么填充预设图表将非常方便。

我已经查看了数据透视表的帮助字段，但只是没有使它起作用。

SELECT  company,
        CAST(SUM(amount_invoice) AS DECIMAL(18,2))
FROM    invoices
        inner join debtors on debtor_id=debtors.id
WHERE   invoice_date BETWEEN '2019-07-01 00:00:00.000' AND '2019-07-31 00:00:00.000'

非常感谢任何愿意帮助我添加正确格式化所需内容的人。

Answer 1

使用分组依据

SELECT  company,
    CAST(SUM(amount_invoice) AS DECIMAL(18,2))
FROM    invoices
    inner join debtors on debtor_id=debtors.id
WHERE   invoice_date BETWEEN '2019-07-01 00:00:00.000' AND '2019-07-31 00:00:00.000'
GROUP BY company

Answer 2

一些建议：

使用表别名。
限定所有表名。
请勿将BETWEEN用于日期/时间比较。

我建议：

SELECT d.company,
       CAST(SUM(i.amount_invoice) AS DECIMAL(18,2))
FROM invoices i INNER JOIN
     debtors d
     ON i.debtor_id = d.id
WHERE i.invoice_date >= '2019-07-01' AND
      i.invoice_date < '2019-08-01';

亚伦·伯特兰（Aaron Bertrand）的blog很好，解释了为什么不想在两者之间使用。

总和，支点还是大小写？
