The following query works when executed in SequelPro:
SELECT * FROM friend_computer LEFT JOIN computer m ON computer_id = m.id LEFT JOIN computer_status ms ON m.id = ms.computer_id JOIN friend_account pa ON friend_account_id = pa.id WHERE friend_account_id = 1 ORDER BY coalesce(ms.last_connect_time < ms.last_disconnect_time, -1) asc;
But in Hibernate, I keep getting a syntax error for the below:
String sql2 = "SELECT pm FROM FriendComputer pm LEFT JOIN FETCH pm.computer m JOIN FETCH pm.friendAccount pa " +
"WHERE pm.friendAccount.id = :friendId AND pm.computer = m ORDER BY coalesce((m.computerStatus.lastDisconnectTime < m.computerStatus.lastConnectTime),-1 ) " + sortOrder;
org.hibernate.query.Query q = session().createQuery(sql2).setParameter("friendId", friendId);
The syntax error is due to the coalesce function. I can't find any online resources about how to use an expression inside coalesce.
What are you trying to do? An explicit case would at least provide clarity:
order by (case when ms.last_connect_time < ms.last_disconnect_time then 2
when ms.last_connect_time >= ms.last_disconnect_time 1
else 0
end)

I read a lot of similar questions but didn't find a solution for me. Basically I would like to have a where clause (AND PEKP.VORGANGS_ART = 'BE') only if a special condition (PFSP.EINKAUFS_KZ = 2) is true.
I tried in many ways like that:
SELECT *
FROM PFSP
LEFT OUTER JOIN PFAK on PFSP.RUECKMELDE_NR = PFAK.RUECKMELDE_NR
LEFT OUTER JOIN PEKP ON (PFSP.BESTELL_NR=PEKP.VORGANGS_NR)
AND (PFSP.BESTELL_POS_NR=PEKP.VORGANGS_POS_NR)
LEFT OUTER JOIN PMLB ON PFSP.KOMPONENTEN_ARTIKEL_NR=PMLB.ARTIKEL_NR
WHERE PFAK.KD_VORGANGS_NR = '910-001213'
AND PFSP.RUECKMELDE_STATUS = '3'
AND PFSP.BESCHAFFUNGSKENNER = 'F'
AND CASE PFSP.EINKAUFS_KZ
WHEN 2 THEN PEKP.VORGANGS_ART = 'BE'
END
but I keep getting errors:
wrong syntax near '='"
Skip the CASE, use AND/OR instead:
AND (PFSP.EINKAUFS_KZ <> 2 OR PEKP.VORGANGS_ART = 'BE')
If PFSP.EINKAUFS_KZ = 2, then PEKP.VORGANGS_ART must be equal to 'BE'.
If PFSP.EINKAUFS_KZ <> 2, it doesn't matter what PEKP.VORGANGS_ART is.
With this CASE expression:
AND 1 = CASE
WHEN PFSP.EINKAUFS_KZ = 2 AND PEKP.VORGANGS_ART = 'BE' THEN 1
WHEN PFSP.EINKAUFS_KZ = 2 THEN 0
ELSE 1
END
The order of the conditions is important.
You probably want something like:
AND (
(PFSP.EINKAUFS_KZ = 2 AND PEKP.VORGANGS_ART='BE')
OR PFSP.EINKAUFS_KZ <> 2 --You may need to catch NULL as well
)
SELECT *
FROM PFSP
LEFT OUTER JOIN PFAK on PFSP.RUECKMELDE_NR = PFAK.RUECKMELDE_NR
LEFT OUTER JOIN PEKP ON (PFSP.BESTELL_NR=PEKP.VORGANGS_NR)
AND (PFSP.BESTELL_POS_NR=PEKP.VORGANGS_POS_NR)
LEFT OUTER JOIN PMLB ON PFSP.KOMPONENTEN_ARTIKEL_NR=PMLB.ARTIKEL_NR
WHERE PFAK.KD_VORGANGS_NR = '910-001213'
AND PFSP.RUECKMELDE_STATUS = '3'
AND PFSP.BESCHAFFUNGSKENNER = 'F'
AND ((PFSP.EINKAUFS_KZ = 2 AND PEKP.VORGANGS_ART = 'BE') OR (PFSP.EINKAUFS_KZ <> 2) )
I have the following query
SELECT
dtc.coupon_type_company_name,
COUNT(*) * dtc.coupon_type_company_coupon_amount AS 'Total_Coupon_To_Be_Used',
dtc.coupon_type_company_coupon_months_combinable
FROM
[dbo].[coupon_type_Company_User] dtcu
JOIN
coupon_type_Company dtc ON dtcu.coupon_type_Company_ID = dtc.id
JOIN
person p ON dtcu.userID = p.userID
WHERE
coupon_type_company_coupon_is_combinable = 1
OR coupon_type_company_has_coupon = 1
AND dtc.companyID = 1081
AND p.is_active = 1
GROUP BY
dtc.coupon_type_company_name,dtc.coupon_type_company_coupon_amount,
dtc.coupon_type_company_coupon_months_combinable
This returns the following:
What I want to have however is just one column and one row that should take the SUM of my middle column (count(*)*dtc.coupon_type_company_coupon_amount).
How could I achieve this and prevent doing this in my code backend (C#)
You can wrap your query like this:
SELECT SUM(Total_Coupon_To_Be_Used) AS the_sum
FROM (
your query
) s
Use a "Table Expression", as in:
select sum(Total_Coupon_To_Be_Used) from (
SELECT dtc.coupon_type_company_name,
count(*) * dtc.coupon_type_company_coupon_amount as 'Total_Coupon_To_Be_Used',
dtc.coupon_type_company_coupon_months_combinable
FROM [dbo].[coupon_type_Company_User] dtcu
JOIN coupon_type_Company dtc ON dtcu.coupon_type_Company_ID = dtc.id
JOIN person p ON dtcu.userID = p.userID
WHERE coupon_type_company_coupon_is_combinable = 1
or coupon_type_company_has_coupon = 1
and dtc.companyID = 1081
AND p.is_active = 1
GROUP BY
dtc.coupon_type_company_name,dtc.coupon_type_company_coupon_amount,
dtc.coupon_type_company_coupon_months_combinable
) x
I am working on Microsoft SQL Server 2014 and I have the following SQL query which works:
SELECT
h.entidade, h.datadoc, h.tipodoc, h.numdoc,
(SELECT valortotal -
(SELECT COALESCE(SUM(l.valorrec), 0)
FROM LinhasLiq as l
INNER JOIN cabliq ON l.IdCabLiq = CabLiq.id
INNER JOIN Historico ON L.IdHistorico = Historico.id
WHERE cabliq.DataDoc < '01/05/2015'
AND historico.id = h.id)) as 'valor pendente',
coalesce(documentosCCT.Descricao,'')
+' '+ CASE WHEN h.modulo<>'V' THEN coalesce(documentosVenda.Descricao,'') else'' END
+' '+ coalesce(h.descricao,'') AS descricaogeral
FROM
Historico h
LEFT JOIN
documentosCCT ON h.TipoDoc = documentosCCT.Documento
LEFT JOIN
documentosVenda ON h.Tipodoc = documentosVenda.Documento
WHERE
h.entidade = 'ta0141' AND
(h.tipoentidade = 'C' OR h.tipoentidade = 'F')
ORDER BY
datadoc ASC
and this specific expression
(select valortotal - (SELECT COALESCE(SUM(l.valorrec),0) from LinhasLiq as l
inner join cabliq on l.IdCabLiq = CabLiq.id
inner join Historico on L.IdHistorico = Historico.id
where cabliq.DataDoc < '01/05/2015' and historico.id = h.id)) as 'valor pendente'
returns a lot of 0 values, so how can I put this entire expression in a having X > 0 clause, or any other way as long as the rows with this expression = 0 doesn't show?
Many thanks.
i don't know what is your circumstances if it is feasible try to make query in single select statement instead of multiple
Don't make an alias valor pendente like that should be valorpendente
Now you can use CTE
;WITH CTE AS
(
-- YOUR QUERY
)
SELECT * FROM CTE
WHERE valorpendente > 0
I am writing a stored procedure that adds the counts to two fields. I have the following code:
SELECT Distinct DateTime1,SUM(TICKETREQ1)SUMREQ, SUM(TicketPU1)SUMPU1, (count(*))AS GRADCOUNT
FROM TABLEA
WHERE YEAR = '2015'
AND TicketReq1 > 0
group by DateTime1
Select DISTINCT(DateTime2),SUM(TicketReq2) SUMREQ,SUM(TicketPU2)SUMPU2, (count(*))AS GRADCOUNT
from TABLEA
where TicketReq2 > 0
and YEAR = '2015'
Group by DateTime2;
SELECT Distinct c.DateTime1,SUM(c.TICKETREQ1 + b.TicketReq2)SUMREQ, SUM(c.TicketPU1 + b.TicketPU2)SUMPU1, (count(b.id) + count(c.id))AS GRADCOUNT
FROM TABLEA c
LEFT JOIN TABLEA b
ON (b.DateTime2 = c.DateTime1
AND b.TicketReq2 > 0
AND b.YEAR = '2015')
WHERE c.YEAR = '2015'
AND c.TicketReq1 > 0
group by c.DateTime1
This returns:
For some ceremonies the second query does bring in results and adds them correctly. But if there are no records then it fails.
How can I get it to join the two counts together (Query 1 and 2) so that Query 3 displays both counts even when there is no match
The problem is the SUM statements on query #3. b.TicketReq2 is null, therefore SUM(c.TICKETREQ1 + b.TicketReq2) should encounter an error. Try using ISNULL(b.TicketReq2, 0) in your SUM function calls.
Try full outer join instead of left join
SELECT Distinct c.CeremonyDateTime1,SUM(c.TICKETREQ1 + b.TicketReq2)SUMREQ, SUM(c.TicketPU1 + b.TicketPU2)SUMPU1, (count(b.gid) + count(c.gid))AS GRADCOUNT
FROM ComTicket c
FULL OUTER JOIN ComTicket b
ON (b.CeremonyDateTime2 = c.CeremonyDateTime1
AND b.TicketReq2 > 0
AND b.Gradterm = '201540')
WHERE c.gradterm = '201540'
AND c.TicketReq1 > 0
group by c.CeremonyDateTime1

when executing am getting this error
ERROR: column "gtab12.acgrcode" must appear in the GROUP BY clause or
be used in an aggregate function
Note : before modifying this query the aggreagte functions are gathering from sub selects see it here
You are using aggregate functions (SUM) in some columns so you need to use aggregates functions on other ones or group by columns.
