There is my request to find actualities on my website, I got error in this request and I don't know what i need to do for solve this error
Error:
Column "quote_plus_normal_gr_publi.id_post_normal" must appear in the GROUP BY clause or be used in an aggregate fun
Query:
SELECT
publi.date, publi.mess, publi, publi.profil, publi.color,
publi.name, publi.search
FROM
publi
INNER JOIN
(SELECT
id_post_normal, COUNT(id_post_normal)
FROM
quote_plus_normal_gr_publi
ORDER BY
id_post_normal) q ON q.id_post_normal = publi.id_post_normal
WHERE
publi.id_personnes = 1
ORDER BY
date DESC
I think something wrong in your select statement
SELECT publi.date, publi.mess, publi, publi.profil, publi.color, publi.name, publi.search
FROM publi
INNER JOIN (
SELECT id_post_normal, COUNT(id_post_normal)
FROM quote_plus_normal_gr_publi
ORDER BY id_post_normal
) q
ON q.id_post_normal = publi.id_post_normal
WHERE publi.id_personnes = 1
ORDER BY date DESC
in first select there are just publi and don't have column to call
select publi.date, publi.mess, publi, publi.profil
so i try query and make similar to you and i don't have any error to show.
first why the error show up group by? do you try another query? not this query?

I am trying to select from one table using the select result from another table. I can run this in two queries but would like to optimize it into just one.
First query.. Select ids where matching other id
select id from lookuptable where paid = '547'
This results in something like this
6316352
6316353
6318409
6318410
6320468
6320469
6320470
6322526
6322527
6324586
6324587
6326648
I would like to then use this result to make another selection. I can do it manually like below. Note, there could be many rows with these values so I've been using a IN statement
select * from "othertable" where id in (6316352,6316353,6318409,6318410,6320468,6320469,6320470,6322526,6322527,6324586,6324587,6326648);
select
ot.*
from
"othertable" as ot
join
lookuptable as lt
on
ot.id = lt.id
where
lt.paid = '547'
The IN operator supports not just value lists but also subqueries, so you can literally write
select * from "othertable" where id in (select id from lookuptable where paid = '547');
I have this query I have written in PostgreSQL that returns an error saying:
[Err] ERROR:
LINE 3: FROM (SELECT DISTINCT (identifiant) AS made_only_recharge
This is the whole query:
SELECT COUNT (made_only_recharge) AS made_only_recharge
FROM (
SELECT DISTINCT (identifiant) AS made_only_recharge
FROM cdr_data
WHERE CALLEDNUMBER = '0130'
EXCEPT
SELECT DISTINCT (identifiant) AS made_only_recharge
FROM cdr_data
WHERE CALLEDNUMBER != '0130'
)
I have a similar query in Oracle that works fine. The only change is where I have EXCEPT in Oracle I have replaced it with the MINUS key word. I am new to Postgres and don't know what it is asking for. What's the correct way of handling this?
Add an ALIAS onto the subquery,
SELECT COUNT(made_only_recharge) AS made_only_recharge
FROM
(
SELECT DISTINCT (identifiant) AS made_only_recharge
FROM cdr_data
WHERE CALLEDNUMBER = '0130'
EXCEPT
SELECT DISTINCT (identifiant) AS made_only_recharge
FROM cdr_data
WHERE CALLEDNUMBER != '0130'
) AS derivedTable -- <<== HERE
In the case of nested tables, some DBMS require to use an alias like MySQL and Oracle but others do not have such a strict requirement, but still allow to add them to substitute the result of the inner query.
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)
INNER JOIN FORMACAOTURMAS Turma ON (Falta.FA_TURMA = Turma.FT_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 just created a temporary table as:
create temporary table userAndProductSales as
select p.p_name, u.u_name, u.s_price, u.quantity
from product p
join userAndStates u
on p.s_id = u.s_id
Now I want to select some columns with a particular order. For example, I want the select to give me an output of:
u_name1 p_name1
u_name1 p_name2
u_name1 p_name3
u_name1 p_name4
...
u_name2 p_name1
u_name2 p_name2
u_name2 p_name3
....
and so on and so forth. How do I get this ouput? I've tried something on the lines of:
select (select u_name from userandproductsales order by u_name), p_name from userandproductsales
but I'm getting an error
UPDATE: Figured out that the table I'm joining isn't giving me the correct data I want. Thanks for the help though.
Here is how to use ORDER BY :
SELECT * from userandstatesales
order by u_name , p_name
Unless there is a reason for creating a temporary table (like needing to access it later in the same session), you should avoid the expense and simply do a order by from your select. For example:
select p.p_name, u.u_name, u.s_price, u.quantity
from product p
join userAndStates u
on p.s_id = u.s_id
order by u.u_name, p.p_name;
I have two entities STOCK(name,amount) and PC_SYSTEMS(name,c_name), and i wish to update the components needed to create the PC_system "Alienware", therefore i want it to subtract 1 from the amount of the components, needed to create the alienware system, in Stock.
Here's my query:
"UPDATE stock SET amount=amount-1 WHERE name = ( SELECT p.c_name FROM pc_systems p WHERE p.name='Alienware');"
I get a weird error that says:
" more than one row returned by a subquery used as an expression"
Would be happy if someone could help.
Edit:
I SOLVED this by putting an "IN" in my query instead of "=". Final code:
UPDATE stock SET amount=amount-1 WHERE name IN ( SELECT p.c_name FROM pc_systems p WHERE p.name='Alienware');
What it means is this SQL returns more than 1 row. Make it so it returns exactly 1 row only.
SELECT p.c_name FROM pc_systems p WHERE p.name='Alienware'
Since your subquery is returning more than one record you cannot use that syntax. try something like this:
UPDATE S
SET S.amount=S.amount-1
FROM Stock S
INNER JOIN pc_systems p
ON S.name = p.c_name
WHERE p.name='Alienware'
or try this:
update stock
set s.amount=s.amount-1
from stock s
inner join pc_systems p on S.name = p.c_name
where p.name='Alienware'
