I am a beginner and need help: I have to convert my SQL query into a stored procedure. this is my original query :

SELECT TM.MaintenanceID, TM.TruckNumber, TI.TruckDescription, TI.TruckCurrentMileage, LUMT.MaintenanceType, LUTT.TruckType, TM.MaintenanceStartDate, TM.MaintenanceEndDate, LUTB.TruckBodyType FROM TruckMaintenance AS TM

JOIN dbo.TruckInformation AS TI on TI.TruckNumber = TM.TruckNumber

JOIN dbo.LUTruckType AS LUTT ON LUTT.TruckTypeID = TI.TruckTypeID

JOIN dbo.LUMaintenanceType AS LUMT ON LUMT.MaintenanceTypeID = TM.MaintenanceTypeID

JOIN dbo.LUTruckBodyType AS LUTB ON LUTB.TruckBodyTypeID = TI.TruckBodyTypeID

WHERE MaintenanceStartDate BETWEEN '2018-01-01' AND '2018-12-31'

ORDER BY LUTT.TruckType ASC, TM.MaintenanceStartDate ASC.

This is my stored procedure that when i execute results in nothing

CREATE PROCEDURE [dbo].[TruckMaintenanceDates] (@MaintenanceStartDate date, @MaintenanceEndDate date)

AS

BEGIN

SELECT TM.MaintenanceID,

TM.TruckNumber,

TI.TruckDescription,

TI.TruckCurrentMileage,

LUMT.MaintenanceType,

LUTT.TruckType,

TM.MaintenanceStartDate,

TM.MaintenanceEndDate,

LUTB.TruckBodyType

FROM TruckMaintenance AS TM

JOIN dbo.TruckInformation AS TI

on TI.TruckNumber = TM.TruckNumber

JOIN dbo.LUTruckType AS LUTT

ON LUTT.TruckTypeID = TI.TruckTypeID

JOIN dbo.LUMaintenanceType AS LUMT

ON LUMT.MaintenanceTypeID = TM.MaintenanceID

JOIN dbo.LUTruckBodyType AS LUTB

ON LUTB.TruckBodyTypeID = TI.TruckBodyTypeID

WHERE

MaintenanceStartDate BETWEEN @MaintenanceStartDate AND @MaintenanceEndDate

ORDER BY LUTT.TruckType ASC,

TM.MaintenanceStartDate ASC

SET NOCOUNT ON;

END
