ORDER BY
i ROW_NUMBER
klausulen garanterar inte ordningen på resultatuppsättningen.
ROW_NUMBER
använder vanligtvis sortering i frågeplanen vilket resulterar i att värdena kommer ut försorterade.
Detta är en biverkning och bör inte förlitas på.
DISTINCT
använder Hash Match (Aggregate)
vilket bryter sorteringen.
Lägg till ORDER BY
klausul till slutet av frågan:
SELECT DISTINCT (ID), State_Id, Name_Of_Trip, Date_Of_Travel, Creation_Date, Locking_Id, Applicant_Name, Reference_Number, State_Name
FROM (
SELECT app.ID, app.State_Id, app.Name_Of_Trip, app.Date_Of_Travel,
app.Creation_Date, app.Locking_Id, app.Applicant_Name, app.Reference_Number,
State.Name AS State_Name, ROW_NUMBER() OVER(ORDER BY Reference_Number DESC) as rowNum
FROM Application_Leg AS app
INNER JOIN
State AS state
ON app.State_Id = state.ID
WHERE app.State_Id IN (5, 6, 8)
AND app.Organisation_Id = 12
AND Leg_Number IN
(
SELECT Leg_Number
FROM Application_Leg as al
INNER JOIN
Organisation as org
ON al.Organisation_Id = org.ID
WHERE al.ID = app.ID
AND org.Approval_Required = 1
AND Mode_Of_Transport = 1
)
) AS pagedApplications
WHERE rowNum BETWEEN 0 AND (0 + 10)
ORDER BY
ReferenceNumber DESC
Observera också att den inte returnerar 10
distinkta resultat returnerar den DISTINCT
av de första 10
resultat.
Om du vill ha det förra, använd detta:
SELECT DISTINCT TOP 10 ID, State_Id, Name_Of_Trip, Date_Of_Travel, Creation_Date, Locking_Id, Applicant_Name, Reference_Number, State_Name
FROM (
SELECT app.ID, app.State_Id, app.Name_Of_Trip, app.Date_Of_Travel,
app.Creation_Date, app.Locking_Id, app.Applicant_Name, app.Reference_Number,
State.Name AS State_Name
FROM Application_Leg AS app
INNER JOIN
State AS state
ON app.State_Id = state.ID
WHERE app.State_Id IN (5, 6, 8)
AND app.Organisation_Id = 12
AND EXISTS
(
SELECT Leg_Number
FROM Application_Leg AS al
INNER JOIN
Organisation as org
ON al.Organisation_Id = org.ID
WHERE al.ID = app.ID
AND al.LegNumber = app.LegNumber
AND org.Approval_Required = 1
AND Mode_Of_Transport = 1
)
) AS pagedApplications
ORDER BY
ReferenceNumber DESC
