order by in UNION clauses existing a view in left join - sql

Question

I need to order the results by one attribute: Series (for each table). There is also a view in the queries...
The original query is:
select zz.Id
,t1.Series
,t1.SeriesType
from table 1 t1
inner join another_table (...)
left join view (...)
UNION
select zz.Id
,t2.Series
,t2.SeriesType
from table 2 t2
inner join another_table (...)
left join view (...)
UNION
select zz.Id
,t3.Series
,t3.SeriesType
from table 3 t3
inner join another_table (...)
left join view (...)
order zz.Id
this works, but only gives the order for zz.Id. How to achieve order for the Series column for each table?
I have tried with:
select *
from
(
SELECT TOP 100 PERCENT zz.Id
,t1.Series
,t1.SeriesType
from table 1 t1
inner join another_table (...)
left join view (...)
order by t1.Series) as table1
UNION
select *
from
(
SELECT TOP 100 PERCENT zz.Id
,t2.Series
,t2.SeriesType
from table 2 t2
inner join another_table (...)
left join view (...)
order by t2.Series) as table2
UNION
select *
from
(
SELECT TOP 100 PERCENT zz.Id
,t3.Series
,t3.SeriesType
from table 3 t3
inner join another_table (...)
left join view (...)
order by t3.Series) as table3
.
all tables are connected by one single table and this zz.id is unique for table1, table2, table3. (I see it is not possible to sort out at same time Id and series. so I will only sort out the series by each type of series). Thanks.
for example table 1 is:
zz.Id t1.series SERIES_Type
---------------------------------
1 4545 1
2 5655 1
3 2344 1
table 2
zz.Id t2.series SERIES_Type
---------------------------------
4 4546 2
table 3
zz.Id t3.series SERIES_Type
--------------------------------
5 545 3
6 343 3
7 2344 3
final result should be:
zz.Id series SERIES_Type
--------------------------------
3 2344 1
1 4545 1
2 5655 1
4 4546 2
6 343 3
5 545 3
7 2344 3

Answer 1

Have you tried two keys in the order by?
order Id, SeriestType

Answer 2

Based on your "expected result" all you need is:
order by SeriesType, Series
Am I correct or misunderstood...

Answer 3

Whenever it occurs to you to use "top 100 percent" - stop coding. This does nothing useful EVER. A resultset (which is the only way to look at rows) has no reliable or defined order unless the query that generated it included an order by clause. If you want to order rows according to each query within the union, then you need to add a column to each query that you can include in the final sort by clause.
As an example, this adds a column named srt (because "sort" is a reserved word - pick a name meaningful to you). Each participating query in the union is assigned a value that can be used to identify the "group". Again - make it meaningful to you. That column is included in the final sort by clause as the first column and will "group" rows.
use tempdb;
go
declare #tbl table (id int not null, series varchar(10) not null, seriestype varchar(10) not null);
insert #tbl(id, series, seriestype) values (1, '4521', 1), (1, '3011', 1), (2, '9999', 2), (3, '0000', 1), (3, '1111', 1);
select id, series, seriestype, 1 as srt from #tbl where id = 1
union all
select id, series, seriestype, 2 as srt from #tbl where id = 2
union all
select id, series, seriestype, 3 as srt from #tbl where id = 3
order by srt, id, series;
Now that you have updated your post, it seems you might be able to sort by seriestype. But that might be accidental due to your query logic and the data that exists in your tables. Only you can know if that is correct. TBH, I find the use of a union (vis-a-vis your sample output) suspicious.
And one final note. If you do not want to see the srt column in the final resultset, that can be arranged.
