I have to tables : mutation and ann_commune. The colums code_postal and id_commune are in ann_commune, all the other ones in mutation.
I need to get together the average for the top 3 values of several departments
WITH six as (
SELECT commune as commune_six, AVG(valeur_fonciere) as moyenne_six
FROM mutation
LEFT JOIN ann_commune on mutation.id_commune = ann_commune.id_commune
WHERE code_postal LIKE '06%'
GROUP BY commune_six
ORDER BY moyenne_six DESC
LIMIT 3
),
treize as (
SELECT commune as commune_treize, AVG(valeur_fonciere) as moyenne_treize
FROM mutation
LEFT JOIN ann_commune on mutation.id_commune = ann_commune.id_commune
WHERE code_postal LIKE '13%'
GROUP BY commune_treize
ORDER BY moyenne_treize DESC
LIMIT 3
)
select AVG(moyenne_six)::NUMERIC(7,0) as Moyenne_top3_06,
AVG(moyenne_treize)::NUMERIC(7,0) as Moyenne_top3_13
from six, treize
I am sure there is a way to create a nicer quode, because I have to do the same with 10 averages. I did not find the solutions, but I am sure it exists.
Thank you in advance :).
I have a set of data like this
The Result should look Like this
My Query
SELECT max(pi.pi_serial) AS proforma_invoice_id,
max(mo.manufacturing_order_master_id) AS manufacturing_order_master_id,
max(pi.amount_in_local_currency) AS sales_value,
FROM proforma_invoice pi
JOIN schema_order_map som ON pi.pi_serial = som.pi_id
LEFT JOIN manufacturing_order_master mo ON som.mo_id = mo.manufacturing_order_master_id
WHERE to_date(pi.proforma_invoice_date, 'DD/MM/YYYY') BETWEEN to_date('01/03/2021', 'DD/MM/YYYY') AND to_date('19/04/2021', 'DD/MM/YYYY')
AND pi.pi_serial in (9221,
9299)
GROUP BY mo.manufacturing_order_master_id,
pi.pi_serial
ORDER BY pi.pi_serial
Option 1: Create a "Running Total" field in Crystal Reports to sum up only one "sales_value" per "proforma_invoice_id".
Option 2: Add a helper column to your Postgresql query like so:
case
when row_number()
over (partition by proforma_invoice_id
order by manufacturing_order_master_id)
= 1
then sales_value
else 0
end
as sales_value
I prepared this SQLFiddle with an example for you (and would of course like to encourage you to do the same for your next db query related question on SO, too :-)
I have store procedure which return data fine and it was developed by some one else who now not in touch.
Output now looks like
Here i am attaching a part of the query which return data.

Order by ID,Ord,BM_Code,LineItem,BrokerName'
Now broker Name is not coming as alphabetical order and it is the issue.
see this line at the bottom Order by ID,Ord,BM_Code,LineItem,BrokerName
When i try to change this order by like Order by ID,Ord,BM_Code,LineItem,BrokerName IN (SELECT BrokerName FROM #Brokers ORDER BY BrokerName ASC)' then getting error like clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.
in my order by there are many columns and data is getting order by that way but i need to show broker name in alphabetical order but i am not being able. so please some one guide me how can i customize this sql.
Here i have not attached my full store procedure code because it is very large. looking for suggestion & help. Thanks
Short version
The ORDER BY is doing what is expected - ordering first by ID, then Ord, then BM_Code, then LineItem, then BrokerName.
Within ID 76187, the next field to order by is Ord - which it sorts from 30911, to 31097.
If it previously ordered by BrokerName, it was only by chance - or that Ord was ordered the same way as BrokerName.
My initial suggestion is to re-order your sort e.g., ORDER BY ID, BM_Code, LineItem, BrokerName, Ord
Longer explanation of issue
In SQL, underlying data is treated as a set and ordering doesn't matter.
For example, if you have a variable #x and you were testing IF #x IN (1,2,3,4,5) will produce the same result as IF #x in (5,4,3,2,1).
In your example, you're putting an ORDER BY into the sub-query you're checking with the IN e.g., ORDER BY ... BrokerName IN (SELECT BrokerName FROM #Brokers ORDER BY BrokerName ASC). The order of that sub-query isn't allowed, and wouldn't do anything anyway.
The only sort that matters (other than for a few things like TOP) is the final sort - when displaying the data.
That being said, even if you removed the ORDER BY in the sub-query, it wouldn't help you with your issue
The SQL is not likely to work anyway - ORDER BY needs a value - you may have needed to make it CASE WHEN BrokerName IN (...) THEN 0 ELSE 1 END
Which also won't help, as the issue is that Ord is sorted before BrokerName anyway.
UPDATE following comment
Fundamentally, the statement that provides the actual report is
SET #sql = '
Select XX.*,'''' scale,Isnull(AllowComma,''FALSE'') AllowComma,Isnull(AllowedDecimalPlace,''0'') AllowedDecimalPlace,
Isnull(AllowPercentageSign,''FALSE'') AllowPercentageSign,Isnull(CurrencySign,'''') CurrencySign,Isnull(BM_Denominator,'''') BM_Denominator
From (<a whole lot of calculations/cpode>) XX
Left Outer Join tblLiConfig ZZ
On XX.Section=ZZ.Section And XX.LineItem=ZZ.LI And ZZ.Ticker='''+#Ticker+'''
Order by ID,Ord,BM_Code,LineItem,BrokerName'
The last line on there provides the ordering of the data coming from this procedure.
To get a different order, you need to change the order of the fields shown - moving BrokerName more towards the start of the list, and Ord towards the end.
e.g.,
SET #sql = '
Select XX.*,'''' scale,Isnull(AllowComma,''FALSE'') AllowComma,Isnull(AllowedDecimalPlace,''0'') AllowedDecimalPlace,
Isnull(AllowPercentageSign,''FALSE'') AllowPercentageSign,Isnull(CurrencySign,'''') CurrencySign,Isnull(BM_Denominator,'''') BM_Denominator
From (<a whole lot of calculations/cpode>) XX
Left Outer Join tblLiConfig ZZ
On XX.Section=ZZ.Section And XX.LineItem=ZZ.LI And ZZ.Ticker='''+#Ticker+'''
Order by ID,BrokerName,BM_Code,LineItem,Ord'
The above probably sorts by BrokerName too early - but it's up to you to determine what you need.
I'm trying create a SELECT with GROUP BY in Firebird but I can't have any success. How could I do this ?
Exception
Can't format message 13:896 -- message file C:\firebird.msg not found.
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).

trying
SELECT FA_DATA, FA_CODALUNO, FA_MATERIA, FA_TURMA, FA_QTDFALTA,
ALU_CODIGO, ALU_NOME,
M_CODIGO, M_DESCRICAO,
FT_CODIGO, FT_ANOLETIVO, FT_TURMA
FROM FALTAS Falta
INNER JOIN ALUNOS Aluno ON (Falta.FA_CODALUNO = Aluno.ALU_CODIGO)
INNER JOIN MATERIAS Materia ON (Falta.FA_MATERIA = Materia.M_CODIGO)

WHERE (Falta.FA_CODALUNO = 238) AND (Turma.FT_ANOLETIVO = 2015)
GROUP BY Materia.M_CODIGO
Simple use of group by in firebird,group by all columns
select * from T1 t
where t.id in
(SELECT t.id FROM T1 t
INNER JOIN T2 j ON j.id = t.jid
WHERE t.id = 1
GROUP BY t.id)
Using GROUP BY doesn't make sense in your example code. It is only useful when using aggregate functions (+ some other minor uses). In any case, Firebird requires you to specify all columns from the SELECT column list except those with aggregate functions in the GROUP BY clause.
Note that this is more restrictive than the SQL standard, which allows you to leave out functionally dependent columns (ie if you specify a primary key or unique key, you don't need to specify the other columns of that table).
You don't specify why you want to group (because it doesn't make much sense to do it with this query). Maybe instead you want to ORDER BY, or you want the first row for each M_CODIGO.
I have the next query which does not work:
UPDATE item
SET popularity= (CASE
WHEN (select SUM(io.quantity) from item i NATURAL JOIN itemorder io GROUP BY io.item_id) > 3 THEN TRUE
ELSE FALSE
END);
Here I want to compare each line of inner SELECT SUM value with 3 and update popularity. But SQL gives error:
ERROR: more than one row returned by a subquery used as an expression
I understand that inner SELECT returns many values, but can smb help me in how to compare each line. In other words make loop.
When using a subquery you need to get a single row back, so you're effectively doing a query for each record in the item table.
UPDATE item i
SET popularity = (SELECT SUM(io.quantity) FROM itemorder io
WHERE io.item_id = i.item_id) > 3;
An alternative (which is a postgresql extension) is to use a derived table in a FROM clause.
UPDATE item i2
SET popularity = x.orders > 3
FROM (select i.item_id, SUM(io.quantity) as orders
from item i NATURAL JOIN itemorder io GROUP BY io.item_id)
as x(item_id,orders)
WHERE i2.item_id = x.item_id
Here you're doing a single group clause as you had, and we're joining the table to be updated with the results of the group.
