FirebirdSQL聯盟重複記錄

Question

使用FirebirdSQL 3.0.2。我正在嘗試使用固定行來提取報告。意思是，我想每次都有一定數量的行。如果結果集中不存在某行，我想顯示缺失的行的值爲零。

爲此，我有一個虛擬表RAPOR_EK，將所有可能的行組合包含在行中。我在我的主要報告SQL中使用UNION選擇該表。

我的問題是關於重複的記錄。在我的主要報告SQL中選擇了一條記錄的情況下，我從虛擬表中選擇了一條附加記錄。

表結構，虛擬表記錄，報表SQL和報表SQL輸出包含在下面。您可以在報表SQL輸出中的行號1-2,5-6,7-8等中看到重複的記錄。

我很感激任何幫助。

Answer 1

鑑於您的數據的複雜性，我創建了一個簡單的模式來演示解決方案：

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); 

凡report_source有與您的rapor_ek和report_data相同的角色tablo_medas。

我們得到你所需要的數據，我們從report_source選擇所有的行和左連接到report_data，用默認值替換null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) 

其中產量：

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

但是，你的代碼並不那麼簡單，因爲你的where子句中也有條件將左連接轉換爲內連接。要獲得默認值的報表數據，該查詢需要採取的report_data的地方，換句話說：

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) 

您可能還需要更換與on dt.report_id_1 = src.report_id_1 and dt.report_id_1 = src.report_id_2
