How to pass a parameters in native query for stored procedure

Question

I'm trying to pass parameters for stored procedure in native query, url is http://localhost:3025/bbr?BatteryBankID=1&fromDate=2017-01-10&toDate=2017-12-25

STORED PROCEDURE

Alter PROCEDURE [dbo].[Sample]
@BatteryBankID Int,
@fromDate DateTime,
@toDate DateTime

AS BEGIN

select 
bbr.StrVoltage,bbr.ChrgCurr
from BatteryBankReadings bbr
where bbr.BatteryBankID = @BatteryBankID 
and ReadTime between @fromDate and @toDate

END
GO

REPOSITORY

public interface SampleRepo extends CrudRepository<BatteryBankReadings, Integer> {


    @Query(value = "{call Sample :BatteryBankID, ':fromDate', ':toDate'}", nativeQuery = true)
    public List<BatteryBankReadings> samp(@Param("BatteryBankID") int BatteryBankID, @Param("fromDate") String fromDate,@Param("toDate") String toDate);
}

EXCEPTION:

java.lang.IllegalArgumentException: Parameter with that name [fromDate] did not exist

Answer 1

by keeping parameters within the parenthesis it works,

public interface SampleRepo extends CrudRepository<BatteryBankReadings, Integer> {

        @Query(value = "{call Sample (:BatteryBankID, :fromDate, :toDate)}", nativeQuery = true)
        public List<BatteryBankReadings> samp(@Param("BatteryBankID") int BatteryBankID, @Param("fromDate") String fromDate,@Param("toDate") String toDate);
    }
