如何获取单独的行，如果分组，这些行将具有特定的总和

Question

我使用的数据库是 Firebird 2.5。

我只想 select 数据，如果我对列 money 求和，我会得到所有人的所有行，这些行对他们的 money > 0 求和，而且它应该包含如果该人存在 money = 0 的行。

示例：

select name, surname, country, money from person group by 1,2,3 having sum(money)>0

它给了我：

SQL Error [335544824] [42000]: Dynamic SQL Error; SQL error code = -104; Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause) [SQLState:42000, ISC error code:335544824]
  Dynamic SQL Error; SQL error code = -104; Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause) [SQLState:42000, ISC error code:335544824]
    Dynamic SQL Error
      SQL error code = -104
      Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause)

但是如果我将 money 列添加到组中，它会起作用，但它不会 return 包含 money = 0:

的行

select name, surname, country, money from person group by 1,2,3,4 having sum(money)>0

这是一个错误：

    SELECT stag, COMMESSA, MODELLO, linea, DATA_PROD, finiti
        FROM JAVA_PRODUTTIVITA 
    GROUP BY stag, commessa, MODELLO, linea, DATA_PROD 
    HAVING sum(finiti)>0;

但如果我在组中添加 finiti:

    SELECT stag, COMMESSA, MODELLO, linea, DATA_PROD, finiti
        FROM JAVA_PRODUTTIVITA 
    GROUP BY stag, commessa, MODELLO, linea, DATA_PROD, finiti 
    HAVING sum(finiti)>0;

结果：

STAG |COMMESSA |MODELLO   |LINEA |DATA_PROD           |FINITI |
-----|---------|----------|------|--------------------|-------|

两行之间的某处应该是带有 finiti = 0 的记录，但它不是。

Answer 1

使用您的示例 SQL，以下 SQL 可能有效。

您没有指定键，所以我将您组中的所有字段用于内部联接。

WITH SUMMARY
AS (SELECT NAME,
           SURNAME,
           COUNTRY
    FROM PERSON
    GROUP BY 1,
        2,
        3
    HAVING SUM(MONEY) > 0)
SELECT PERSON.NAME,
       PERSON.SURNAME,
       PERSON.COUNTRY,
       PERSON.MONEY
FROM SUMMARY
INNER JOIN PERSON ON (PERSON.NAME = SUMMARY.NAME AND PERSON.SURNAME = SUMMARY.SURNAME AND PERSON.COUNTRY = SUMMARY.COUNTRY) ;
