FirebirdSQL union duplicate records

210 Views Asked by At

Using FirebirdSQL 3.0.2. I am trying to pull out a report with fixed rows in it. Meaning, I would like to have certain number of rows each time even. If certain row does not exists in result set, I would like to display that missing row having values of zeros.

For that I have a dummy table RAPOR_EK with all possible row combinations included as rows. I select that table using UNION in my main report SQL.

My problem is about duplicate records. Where there is a record selected in my main report SQL, I have one additional record selected from dummy table.

Table structures, dummy table records, report SQL and report SQL output is included below. You can see duplicate records in row numbers 1-2, 5-6, 7-8 and so on in report SQL output.

I appreciate any help.

On BEST ANSWER

Given the complexity of your data, I have created a simplified schema to demonstrate a solution:

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);

Where report_source has the same role as your rapor_ek, and report_data that of tablo_medas.

Now to get the data you need, we select all rows from report_source, and left join to report_data, replacing null values with a default value:

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)

Which yields:

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

However your code isn't that simple, because you also have conditions in your where-clause that transform the left join to an inner join. To get your report data with the defaults, that query needs to take the place of report_data, in other words:

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)

You may also need to replace the join using (report_id_1, report_id_2) with an on dt.report_id_1 = src.report_id_1 and dt.report_id_1 = src.report_id_2
