Question

使用FirebirdSQL 3.0.2。我试图提取一个包含固定行的报告。意思是，我希望每次都有一定数量的行。如果结果集中不存在某个行，我想显示缺少行的值为零。

为此，我有一个虚拟表RAPOR_EK，其中所有可能的行组合都包含在行中。我在主报告SQL中使用UNION选择该表。

我的问题是重复记录。如果在我的主报告SQL中选择了一条记录，我会从虚拟表中选择一条额外的记录。

下面包含表结构，虚拟表记录，报告SQL和报告SQL输出。您可以在报告SQL输出中的行号1-2,5-6,7-8中看到重复记录。

我感谢任何帮助。

Answer 1

鉴于数据的复杂性，我创建了一个简化的模式来演示解决方案：

create table report_source (
  REPORT_ID_1 VARCHAR(25) NOT NULL,
  REPORT_ID_2 VARCHAR(25) NOT NULL,
  CONSTRAINT PK_REPORT_SOURCE PRIMARY KEY (REPORT_ID_1, REPORT_ID_2)
);

create table report_data (
  REPORT_ID_1 VARCHAR(25) NOT NULL,
  REPORT_ID_2 VARCHAR(25) NOT NULL,
  VALUE_1 INT,
  VALUE_2 INT
);

insert into report_source (report_id_1, report_id_2) values ('a', 'a');
insert into report_source (report_id_1, report_id_2) values ('a', 'b');
insert into report_source (report_id_1, report_id_2) values ('b', 'a');
insert into report_source (report_id_1, report_id_2) values ('b', 'b');

insert into report_data (report_id_1, report_id_2, value_1, value_2) values ('a', 'a', 1, 2);
insert into report_data (report_id_1, report_id_2, value_1, value_2) values ('b', 'b', 3, 4);

其中report_source与rapor_ek具有相同的角色，report_data与tablo_medas的角色相同。

现在，为了获取您需要的数据，我们从report_source中选择所有行，然后将其加入report_data，将null值替换为默认值：

select src.report_id_1, src.report_id_2, 
  coalesce(dt.value_1, 0) as value_1, 
  coalesce(dt.value_2, 0) as value_2
from report_source src
left join report_data dt using (report_id_1, report_id_2)

哪个收益率：

a   a   1   2
a   b   0   0
b   a   0   0
b   b   3   4

但是你的代码并不那么简单，因为你的where子句中也有条件将左连接转换为内连接。要使用默认值获取报告数据，该查询需要取代report_data，换句话说：

select src.report_id_1, src.report_id_2, 
  coalesce(dt.value_1, 0) as value_1, 
  coalesce(dt.value_2, 0) as value_2
from report_source src
left join (
    select *
    from report_data
    where <conditions>
    <group by, etc>
) dt using (report_id_1, report_id_2)

您可能还需要将加入using (report_id_1, report_id_2)替换为on dt.report_id_1 = src.report_id_1 and dt.report_id_1 = src.report_id_2
